Use suitability maps as a guide, such as Saskatchewan Crop Insurance Corporation maps and varietal information. Field Peas Field peas can be grown across Saskatchewan, but do not like excess moisture or salt-affected soils. Choose fields that drain well. Peas and lentils are more susceptible to Aphanomyces root rot compared to faba beans and chickpeas. Lentils Lentils are better adapted to the southern and west central part of the province in the Brown and Dark Brown soil zones. The introduction of new market classes and breeding of more determinate varieties (red and small green), has extended lentil production into the Thin Black and Black soil zones. In the moist Black and Grey soil zones, it is often too wet for consistent production of high quality lentils. Excess moisture aggravates disease problems and greatly delays maturity. Chickpeas Soil Zones in Southern Saskatchewan Brown Dark Brown Black Dark Grey Source: Saskatchewan Ministry of Agriculture 02 Grey Chickpeas are best adapted to Brown and Dark Brown soil zones in Saskatchewan. They are not well adapted to saline soils, high moisture areas, soils with high clay content, or soils that are slow to warm in the spring. Chickpeas grow best on well-drained soils and with about 15 to 25 centimetres of seasonal rainfall. The long growing season and indeterminate growth habit of Kabuli-type chickpeas limits production in other areas of the province. Desi chickpea varieties have a shorter growing season and mature earlier than Kabuli varieties, and can be extended into the moist Dark Brown soil zones if grown on stubble or lighter textured soils. Chickpeas are deep rooted and can access water from a greater depth than other pulse crops. Disease resistance, specifically to ascochyta blight, is an important factor in variety selection. Faba Beans Faba beans do best on medium textured soils that are well drained, but able to maintain soil moisture. They are best adapted to the Black soil zones and the northern portions of the Dark Brown soil zones of Saskatchewan. Faba bean responds well to irrigation and can tolerate flooding more than peas, lentils, or chickpeas. The crop is highly resistant to lodging, can provide stubble over the winter months, and can provide more reliable production than field peas in regions that are too moist for peas. Dry Bean Dry bean production in Saskatchewan occurs primarily in irrigated areas near Lake Diefenbaker. Beans are best suited to medium-textured loams in regions that are not prone to late-spring or early-fall frosts. Because the crop has no frost tolerance, areas that are prone to spring frost should be avoided. Beans require warm, moist soil conditions for germination and emergence, and are very sensitive to salinity, soil structure problems, and saturated soils. Choose level fields with good drainage and low levels of soil salinity. Soybean Soybeans are grown mainly in the Dark Brown and Black soil zones in southeastern Saskatchewan on mediumtextured loam soils. They can be grown on clay soils under favourable conditions for emergence. Soybeans do not perform well under dry conditions so sandy soils are not ideal. Moisture during pod set in August is important for maximizing yield. Soybeans are susceptible to spring frost and require warm moist soils for quick germination and emergence.

With regrowth, expect delays in crop staging and maturity, and avoid herbicide applications until plants have had a chance to regrow. Lentil and pea seedlings have survived temperatures of -4°C to -6°C. Dry beans and soybeans have main growing points aboveground and can be severely damaged or killed by spring frosts. Chickpea does have growing points below soil surface during early growth similar to pea and lentil. However, chickpea requires warmer soil which means seeding dates are later than pea and lentil which reduces the risk of spring frosts. Saskatchewan Pulse Crop Seeding and Variety Guide 2016 03 CALCULATING SEED RATES FOR PULSES Plant populations set the stage for the yield potential of a crop. Research has shown that each crop has an optimum plant density that producers should target when seeding their crop. Rates can be adjusted higher or lower depending on the conditions in the field, date of seeding, weed pressure, seed placed fertilizer, and other pressures that may affect emergence or plant stand. In order to calculate your seeding rate, you must know the seed size and germination rate. Pulses vary tremendously in seed size and not knowing your thousand kernel weights (TKW) could mean seeding too heavy and spending more on seed than you need to, or seeding too light and limiting yield potential. Both TKW and germination rate can be obtained with a seed test or measured at home. Emergence rates are more difficult to estimate as it depends not only on germination but also on environmental factors and other factors that can affect establishment such as damage during handling. For pulses, the emergence rates are typically 5–15 per cent lower than the germination rates. The following formula will assist you in determining the target seeding rate for pulse crops: Seeding rate kilograms per hectare (kg/ha) = % field emergence or survival (in whole number, i.e. 85) To convert to pounds per acre (lbs/ac) multiply the seeding rate (in kg/ha) by 0.89.

They are also good scavengers of soil phosphorus. However, pulses do require phosphorus for proper growth, yield potential, and maturity, and application of phosphorus fertilizer may be recommended. Application of phosphorus at seeding time is a great way to manage phosphorus fertility but some pulses are more sensitive to seed placement of phosphorus fertilizer. Dr. Jeff Schoenau at the University of Saskatchewan has identified safe levels of fertilizer that can be seed-placed with pulses in narrow row systems with 15 per cent seedbed utilization (calculate seedbed utilization by dividing width of seed spread from the opener by row spacing). Peas are most sensitive with 15 pounds per acre (lbs/ac) of phosphate (P205) being the maximum that can be put in the seed row before you might end up with significant reduction in emergence. Some starter phosphorus (P) in the seed row below these limits is fine. Chickpea, lentil, and soybean are somewhat more tolerant and can take up to 20 lbs/ac of P205 seed placed under good moisture conditions. Faba bean is the most tolerant of seed-placed P, with a maximum safe seed‑placed rate of 40 lbs/ac of P2O5. For potassium (K2O), use the P2O5 guidelines, making sure the total amount of K2O plus P2O5 does not exceed the minimum safe rate for seed placement. For more information on seed placed fertilizer, see Guidelines for Safe Rates of Fertilizer Placed with the Seed from the Saskatchewan Ministry of Agriculture.

The CDC collaborates with researchers at several locations, including Agriculture and Agri-Food Canada research stations, provincial Agriculture-Applied Research Management sites, and the CanadaSaskatchewan Irrigation Diversification Centre, in order to conduct the trials. The project collects data on varieties from the CDC program, as well as those arising from other public or private pulse breeding programs. Regional Variety Trials in 2015 included 14 pea, 11 lentil, eight dry bean, five chickpea, five white flowered faba bean, and four coloured faba bean sites across Saskatchewan covering the Brown, Dark Brown, Thin Black, and Thick Black soil zones. The soybean regional trials are coordinated by Manitoba Agriculture, Food and Rural Development and occurred at 12 sites across Saskatchewan in 2015. Plant Breeders’ Rights Plant Breeders’ Rights (PBR) are intended to encourage investment in development and promotion of new, improved, and innovative plant varieties for the benefit of growers. Protection of intellectual property rights is important for organizations that are investing in variety development so that they are able to keep reasonable control of the varieties and secure fair compensation for their efforts. Varieties previously protected by PBR remain under the previous rules. Varieties protected since February 27, 2015 will be protected under the new PBR Act and will carry the PBR 91 symbol. The new PBR Act aligns with the UPOV 1991 convention. It extends the right of the breeder to further protect their variety as well as ensuring breeders receive compensation from the use of their technology. With the new PBR Act, the seller and the buyer can both be liable if the seed sale is not approved. The new PBR Act also takes into account the interest of growers. Growers will be able to produce PBR protected varieties for use on their own farm if the original seed was obtained legitimately. Purchasing certified seed is a good way to ensure compliance. Proper documentation, such as retaining the blue seed tags, will be important. For more information, visit pbrfacts.ca. WHAT TO CONSIDER WHEN SELECTING NEW VARIETIES There are various factors to consider when selecting a new variety and it all depends on what your main priority is. Some factors to consider include: • Market – Identify your target market and make sure the variety selected matches the specifications and quality expected by your buyers, such as seed size, colour, functionality, and other attributes. • Herbicide tolerance – Consider the weeds or volunteers that may be present in the field to determine if herbicide tolerant options are a good choice. • Maturity – Identify realistic expectations on maturity needed to achieve optimum yield and quality in your region. • Seed size – If seed size does not affect the market choice, then consider the seeding costs of the variety. Smaller seeded varieties are usually cheaper to seed and have fewer production issues with plugging seeding equipment and other operations. Faba beans are a good example where seed size may be more important. • Disease resistance – Select varieties with better resistance for high risk areas or fields. Resistance is a tool that helps with disease management, but may or may not reduce the reliance on fungicide application. 08 • Crop growth habit and other physiological factors – Factors such as growth habit (determinate or indeterminate), plant height, standability, harvest management, and quality parametres such as resistance to seed coat breakage, bleaching, or others are important. • Yield – This is often the highest priority as it directly relates to the ultimate goal of net returns. In some cases, the advantages and higher performance of new varieties may not necessarily translate into higher yields, due to environment or management practices. If all other factors have been considered, then use yield potential as the deciding factor. UNDERSTANDING MATURITY IN PULSES Days to Maturity Maturity is affected by growing conditions and is only a guide developed under average conditions. It provides a relative comparison for crops and varieties that are grown under similar conditions and planted at the same time. As maturity is delayed into the fall, differences in maturity can be heightened as the days are shorter and temperatures cooler. Under warm, dry years maturity can be shortened and under cool, wet years expect longer maturity. Understanding Soybean Maturity Ratings Soybean maturity ratings are based on three approaches: corn heat units, maturity groupings, and days to maturity. Corn heat units (CHU) are a measure of the heat accumulated over the growing season specific to the physiological needs of a corn plant. The rate of growth of the plant increases with increasing temperatures. CHU accumulation begins on May 15 and ends on the date of the first fall killing frost with temperatures below -3°C. The CHU calculation assumes that no growth occurs when night temperatures are below 4.4°C or day temperatures below 10°C. The calculation also assumes that maximum growth occurs at 30°C and decreases with higher temperatures (Manitoba Agriculture, Food and Rural Development, 2012). The CHU accumulation for an area can be determined by referring to the Saskatchewan Ministry of Agriculture’s Saskatchewan Accumulated Corn Heat Unit Maps for silage and grain production. CHU ratings are assigned by companies and are designed to assist growers in selecting suitable varieties. However, CHU ratings do not always reflect the actual maturity in Saskatchewan, and companies are now also providing an additional maturity rating, based on a United States-based maturity group rating system. The maturity group (MG) rating system classifies soybean varieties MG from 000 in northern areas to IX in southern areas of North America, based on latitude ranges and photoperiod sensitivity. Each maturity group region covers one or two degrees of latitude, or about 200 to 300 kilometres from north to south. For Saskatchewan, soybeans are most suited with 00 and 000 MG. Each MG can have subgroupings with a 0 to 9 decimal number following the group (or zone) number and these decimal places equate to slight increases in maturity. In the 00 maturity ratings, a subgroup of 00.1 would be earlier maturing than 00.9. Note that these maturity group ratings are not entirely standardized between companies. Check with your seed supplier to better understand maturity group ratings. Days to maturity is a direct measure of the days each variety takes to reach physiological maturity and is averaged across locations. The lower the number the earlier maturing the variety was across the sites tested. This value is obtained through the Regional Variety Testing program and is an independent rating. Growers are advised to use all maturity ratings available to choose appropriate varieties for their area. Average Days from Seeding to Swathing Ripeness Peas Medium (M) = 90 days Add three to four days for each rating beyond medium Lentils Early (E) = 100 days Very Late (VL) = 110 days based on May 1 seeding Chickpeas Kabuli 110–120 days Desi 110 days Faba Beans 104–107 days Dry Beans E = 100 days Late (L) = 110 days based on May 20 seeding Soybeans 118 to 128 days Source: Saskatchewan Variety of Grain Crops 2016, Saskatchewan Advisory Council on Grain Crops Saskatchewan Pulse Crop Seeding and Variety Guide 2016 09 DISEASE RESISTANCE Understanding the ratings and how to use them for selecting varieties Disease resistance is an important trait to consider when selecting varieties. Ratings may be obtained from greenhouse or field evaluations and are based on a five-point scale that is used for registration trials: Susceptible (S), Moderately susceptible (MS), Intermediate (I), Moderately Resistant (MR), and Resistant (R). These ratings are now applied across all crops and replace the old ratings of very poor, poor, fair, good, and very good. The ratings are relative as each new variety is compared to existing varieties and ratings for the new variety are based on whether they show lower or high incidence of disease as compared to the existing varieties. Disease pathogens can overcome resistance and variety selection should be combined with agronomic and integrated pest management practices to preserve effectiveness. Rotation of crops and varieties are examples of good management strategies. With diseases, environmental conditions can impact severity. Varieties rated as intermediate (I) can show disease symptoms under favourable conditions, however a variety rated as susceptible (S) would have much more disease under the same conditions. Some diseases are very aggressive and plant resistance to the disease can change over time. Root Rots: Aphanomyces Root rots can include a complex of pathogens such as Fusarium spp., Rhizoctonia solani, or Pythium spp. and more recently Aphanomyces euteiches. There is no indication of differences in susceptibility 10 between varieties or pulse crops for most of the root rot pathogens with the exception of Aphanomyces. Current pea and lentil varieties are all susceptible to Aphanomyces root rot. Faba bean and chickpea varieties have partial resistance to this devastating disease and should be considered for fields where Aphanomyces has been identified as long as the crop is suited for that region. Soybeans are also a nitrogen fixing crop that has resistance to Aphanomyces. However, soybeans are susceptible to Phytopthora root rot which is a disease that has not been much of an issue in Saskatchewan, but is on the radar as soybean acres increase. Ascochyta Blight Management in Chickpea Growers are strongly advised that an initial fungicide application is needed for all chickpea cultivars at the seedling to pre-flowering stage in order to limit early ascochyta spore development and spread. Growers are required to monitor their fields diligently for disease and spray if necessary. Within the Crop Development Centre chickpea breeding program, disease has been managed with a maximum of two fungicide applications in all of their nurseries. Timing for the first spray is very critical, routinely recommended at the 7-10 node stage. It is recommended that chickpea is planted on lighter soil, so avoid heavy clay soil that retains moisture, and avoid lower lying or poorly drained fields. It is also recommended that chickpea is planted on stubble, especially in wet years. Seed Treatments Seed treatments are registered for use with pulses and should be considered if seeding early into cool, wet soils or when the seedborne disease levels are over the threshold. The degree of disease control with seed treatments depends on five factors: 1) fungicide active ingredients, 2) rate of application, 3) seed- and soil-borne fungal diseases present, 4) environmental conditions, and 5) quality of seed coverage. Check individual product labels for specifics. Adequate coverage is important to ensure each seed is protected and the seeds are completely covered (especially important with contact type seed treatments). NITROGEN FIXATION Inoculation Inoculants contain the nitrogen fixing rhizobium species necessary to ensure nodulation and nitrogen fixation. Rhizobium species are specific to each pulse crop as outlined in the table. Pea, lentil and faba bean inoculants contain the same rhizobium species but the individual strain of that species (similar to varieties of crops) may be more effective on one crop or another. Check with the manufacturer if considering using an inoculant on a crop that is not on the label. Rhizobium Species Required for Effective Nodulation Pulse Crops CROP RHIZOBIUM SPECIES REQUIRED FOR EFFECTIVE NODULATION Peas, Lentils, Faba Beans Rhizobium leguminosarum Chickpeas Rhizobium ciceri Dry Beans Rhizobium phaseoli Soybeans Bradyrhizobium japonicum Source: Inoculation of Pulse Crops, Saskatchewan Ministry of Agriculture Pulse crops differ in their ability to fix nitrogen and can be ranked accordingly: Faba bean > pea > chickpea > lentil > soybean > dry bean. Nitrogen fixation is the process by which rhizobia take nitrogen gas from the air within the soil pores and convert it to ammonium (NH4), which is available for use by plants. Although nitrogen fixation is usually sufficient to meet crop needs, soils that are very low in nitrogen, less than 15 pounds per acre (lbs/ac) in the top 12 inches, may benefit from 10 to 20 lbs/ac of nitrogen (N) fertilizer. As a rule of thumb, if soil tests indicate more than 20 lbs/ac of nitrate nitrogen, then no additional N is needed with most pulse crops. However, dry bean is a relatively poor nodulator and benefits from higher applications (50 lbs/ac) of starter nitrogen. Inoculants are products that contain living organisms and should be handled accordingly. Avoid exposure to direct sunlight, heat, or repeated freeze-thaw conditions. Consider application method when using in combination with seed treatments as fungicides can impact rhizobia survival. For best results, apply seed treatments first, allow the seed to dry, then apply the inoculant if using seed applied products (sequential application). Read inoculant and seed treatment labels for more information on seed compatability. Inoculant formulations consists of seed applied technologies such as liquids, peat, and powders, as well as granular formulations. Single inoculant applications are effective for peas, lentils, chickpeas, and faba beans. For soybeans, it is recommended to use dual inoculants such as a seed applied product in combination with granular formulation on land where soybeans are being grown for the first time. Dual inoculation on other pulses has not identified any benefits to date. Saskatchewan Pulse Crop Seeding and Variety Guide 2016 11 PEA VARIETY UPDATE Yellow peas are the most widely grown peas in Saskatchewan followed by green peas and then specialty types such as dun, maple, marrowfat, and forage peas. Most varieties have white flowers and are suitable for human consumption or livestock feed markets. Nearly all varieties are semi-leafless leaf type with tendrils instead of leaflets which help provide better standability. Yellow Peas Dun Peas Marrowfat Peas CDC Meadow has been the most widely grown field pea cultivar in Saskatchewan since 2012 with CDC Golden in second place, according to data from the Saskatchewan Crop Insurance Corporation (SCIC). Newer varieties are gaining ground as growers take advantage of improved genetics including CDC Saffron and CDC Amarillo. AAC Ardill is a new variety with high yield potential. Seed of AAC Ardill may be limited in 2016. CDC Inca is the next step in improved yields but seed will not be available until at least 2017 or 2018. CDC Dakota is the top yielder. Dun peas have purple flowers, pigmented seed coats, and yellow cotyledons. They are dehulled and sold in human consumption markets similar to yellow pea varieties. The pigmented seed coats provide natural protection to various root rot fungi, so typically dun (and maple) pea varieties are quick to emerge with good stands. Marrowfat types are blocky, very large-seeded green cotyledon peas used in specialty snack food markets in Asia. They have white flowers and non-pigmented seed coats. Green Peas CDC Striker was the most widely grown green pea variety in Saskatchewan for the past eight years. The next most widely grown green pea varieties in Saskatchewan in 2015 were CDC Patrick, CDC Raezer, CDC Sage, and CDC Limerick based on SCIC data. CDC Tetris is a newer green variety that has blocky seed shape suitable for specialty markets. CDC Greenwater is the latest green variety with exceptionally high yield potential but seed supply will be limited for 2016. 12 Maple Peas Maple pea varieties available in Western Canada include CDC Acer, CDC Rocket, and CDC Mosaic. CDC Acer and CDC Mosaic have small seed size, with CDC Mosaic having better lodging resistance. CDC Rocket has medium seed size and earlier maturity than CDC Acer and CDC Mosaic. CDC Blazer is the newest maple pea variety with high yield potential and a lighter seed coat. Seed for CDC Blazer will not be available for a few years. Forage Peas CDC Tucker, CDC Leroy, and CDC Horizon are forage pea varieties with high biomass yield, powdery mildew resistance, good lodging resistance, and semi-leafless leaf type. These varieties produce on average four to five tonnes per acre of forage dry matter, similar to that of forage barley, but with greater protein concentration. Certified seed of all varieties is available. Red Peas A new class of red cotyledon peas has emerged and markets are being developed. Redbat 8 is the current variety available.

Lodging can be different than what is stated in the guide as different varieties can respond differently under certain environments. Lodging scores are based on a visual rating with a 9-point scale where 1 = completely upright and 9 = completely lodged. Ratings are developed for each variety at a time of year when differences in standability are noticeable, such as at physiological maturity or close to harvest. The numbers are based on relative comparisons to other varieties in the variety testing program. Lodging ratings overall are done at all stages of variety evaluations and overall years so variety ratings may change over time. Seed Coat Breakage Seed coat breakage ratings are done on varieties during the co-op testing phase. It is an abrasive test where seed coat damage is measured using a specific piece of equipment. This rating is a test of durability of the seed coat and is not a measure of seed coat thickness. Greenness in Yellow Peas Seed samples from variety evaluations of yellow peas are visually rated for green colouring after harvest by an experienced person. Ratings are expressed as a percentage of the seeds in a sample that have obvious green tinge to the whole seed. The green colouring may be contained within the seed coat and/or cotyledons. A rating of Fair (F) means the variety averaged 16–40 per cent seeds with green colour whereas a rating of Good (G) would have 0–15 per cent green tinged seeds. Greenness may be impacted by genetics, environmental conditions, and harvest dates. A later maturing variety may show more greenness in the seed sample due to less mature seed if harvested on the same date as an earlier maturity variety. The impact of greenness is visual and does not affect germination but could affect grade. The Canadian Grain Commission has colour as one of the factors for peas with “good natural colour” required for top grades. Too much green colouring could downgrade the sample due to a “fair colour” rating. Seed Coat Dimpling Seed coat dimpling refers to tiny depressions that give the seed a golfball-like appearance. Seed coat dimpling is a result of genetics and environment. Some varieties are more prone to dimpling than others and dimpling can be found in many other pulse crops. It appears to be more prevalent when cool temperatures occur during seed fill. Seed coat dimpling is a measure of the percentage of seed from a harvested sample that shows dimpling. Very good (VG) ratings have between 0–5 per cent of seeds dimpled, Good (G) between 6–20 per cent, and Fair (F) between 21–50 per cent. Buyers prefer a smooth surface to peas and grading may be impacted. Shrivelled seed is a grading factor under the Canadian Grain Commission and includes seeds that have a severely dimpled surface. Bleaching in Green Peas Green peas are recognized and marketed for their uniform green cotyledon colour. The main pigment responsible for the green colour is chlorophyll. Under certain conditions the chlorophyll is degraded by enzymes and results in a lightening of the green colour which is considered bleaching. Under complete degradation of chlorophyll, the seed becomes yellow. Dr. Tom Warkentin with the University of Saskatchewan’s Crop Development Centre (CDC) suggests growers can minimize bleaching by choosing varieties that have better tolerance to bleaching. As bleaching tolerance is a high priority in the breeding program objectives, most new varieties have good tolerance to bleaching. Saskatchewan Pulse Crop Seeding and Variety Guide 2016 15 LENTIL VARIETY UPDATE Lentil types are classified by seed size and colour. Some varieties have been developed with tolerance to imidazolinone herbicides called Clearfield® and are designated as CL. Red Lentils Small red lentils are the most popular class grown in Saskatchewan. Higher yielding varieties are in pedigreed seed production and may have seed available in 2016 in limited quantities. This includes Clearfield® varieties CDC Impulse and CDC Proclaim (IBC 550) for small reds, and non-Clearfield® variety CDC Roxy for extra small reds. Small red varieties such as CDC Cherie and CDC Scarlet are newer non-Clearfield® varieties that are commercially available. CDC Redmoon (3646-4) is the newest small red variety with further improved yield potential, but will not be commercially available until 2018. Large Red lentils have red cotyledons with a much larger seed size compared to small red lentils. CDC KR-1 (not imidazolinone tolerant) and CDC KR-2 (CL) are higher yielding than CDC Maxim in lentil growing areas and are grown exclusively under contract with AGT Food and Ingredients, through Saskatchewan Pulse Growers’ Tender Release Program. Green Lentils Green lentils are classified by seed size with the small greens sometimes referred to as Eston-type and the large greens referred to as Laird-type. They have green seed coats with a yellow cotyledon. CDC Greenstar (large green) and CDC Asterix (extra small green) are the newest green lentil varieties. They have high yield potential but are not imidazolinone tolerant. 16 CDC Imvincible (small green), CDC Imigreen (medium green), and CDC Impower (large green) are the newest greens with the Clearfield® trait, which offers herbicide tolerance to imidazolinone herbicides. Seed of CDC Greenstar may be limited for 2016. Specialty Lentils French Green lentils have a green marbled seed coat with yellow cotyledons. Seed size is small, most similar to small reds. These lentils retain their shape better than small reds or greens upon cooking. CDC Peridot is the only Clearfield® variety available, which is imidazolinone tolerant, but it is a lower yielding variety than conventional variety of CDC Marble. Green Cotyledon lentils have green cotyledons with small-to-medium seed size. CDC QG-2 is the highest yielding variety with earliest maturity. Green cotyledon lentils are grown exclusively under contract with AGT Food and Ingredients, through Saskatchewan Pulse Growers’ Tender Release Program. Spanish Brown lentils have a gray dotted seed coat with yellow cotyledons. This class is sold primarily into Spain. Seed size is small, most similar to small reds. CDC SB-2 is the latest variety with higher yield and improved disease resistance. Spanish Brown varieties are grown exclusively under contract with Simpson Seeds, through Saskatchewan Pulse Growers’ Tender Release Program.

Tannin type varieties have coloured flowers and are usually larger seeded. Tannin types are targeted for human consumption but can also be fed to livestock or processed. CDC SSNS-1 is a small seeded tannin type that is grown in Saskatchewan and is well-suited for green manure or use in silage mixtures. Zero-tannin type varieties have white flowers and are grown mainly for use in livestock feed industry, but can also be sold into other markets. The smaller seeded zero-tannin varieties Snowbird and CDC Snowdrop are the most widely grown varieties in Saskatchewan.

If outcrossing occurs, the seed from the field may appear uniform but upon replanting the following year a high number of off types will result and marketing the crop will be an issue. The Canadian Seed Growers Association recommends a minimum of 100 metres between different varieties of faba beans, however Dr. Bert Vandenberg with University of Saskatchewan’s Crop Development Centre suggests even further distances should be used, up to 500 metres, to minimize the risk of cross pollination. Faba beans have a high requirement for phosphorus (P). Uptake of P is approximately two kilograms per hectare (kg/ha) for every bushel (bu) produced (89 to 108 kg/ha for 50 bu/ac crop), and about 1.2 kg/ha removed from the field with every bushel produced (55–67 kg/ha for 50 bu/ac crop). Phosphorus response of faba bean is currently under investigation. It is recommended to apply P at removal rates to balance fertility programs for future crops. Faba beans are tolerant to 40 lbs/ac of seed placed fertilizer. Slow down at seeding time to prevent plugging. Faba beans are a larger seed and plugging can occur during seeding time. Reducing seed speed can help slow down the amount of material needing to go through the equipment. Equipment manufacturers have recommendations for alternations or adaptations for seeding large seed crops such as faba beans. 20 DRY BEAN VARIETY UPDATE Dry bean production in Saskatchewan occurs primarily in the irrigation area near Lake Diefenbaker but there are limited acres of dryland production. The majority of the dry beans produced are pinto beans followed by navy, black, and small red beans. Dry bean acreage has been fairly stable around 10,000 acres annually.

Trash management to encourage some blackening of the soil can be advantageous to speed soil warming. They are sensitive to spring frosts as growing point is aboveground. Delay seeding until at least May 10 or later if conditions remain cool. Soybeans are susceptible to several seed and seedling diseases so seed treatment should be considered. Soybeans are prone to iron chlorosis particularly when grown on saturated soils, soils high in calcium carbonates, or on soils with salinity problems. Choose your fields carefully. The maximum amount of phosphate plus potassium fertilizer that can be safely placed with the seed is 20 lbs/ac. Amounts higher than 20 lbs/ac should be banded. Volunteer Roundup Ready® canola is a problem weed. Preemergence herbicides should be considered as part of the weed control program. Additional Information The soybean variety trial is coordinated by Manitoba Agriculture Food and Rural Development. Mean yield of the check variety 23-10RY was 45 bu/ac in the south, and 42 bu/ac in the north. Typical on-farm yields are 25–30 bu/ac. Soybean is not native to the Canadian Prairies and so must be inoculated with soybean inoculant that contains Bradyrhizobium japonicum bacteria.
