It is a presumption that the study could generate philanthropy in Asia that supports paddy science and innovations for the benefit of the entire region. Transplanting of paddy in puddled fields is generally preferred over dry sowing of seeds due to severe problem of weeds. The raising of nursery and manual transplanting are both labour intensive and costly prepositions. The results of the study showed that the cost of operation for sowing paddy using drum seeder was 800 Indian rupee (INR) per ha as compared to INR 30000 per ha in conventional method. The cost of weeding and cost of irrigation in the field of drum seeded paddy and transplanted paddy were INR 700, 1500 and INR 5600, 4800 per ha respectively. Grain yield was 60 Q/ha for drum seeded paddy and 58 Q/ha for transplanted paddy which was not showing a wide difference but yes it was a measurable parameter. Gross return for drum seeded paddy was 90000 INR/ha leading to a net profit of 73900 INR/ha and benefit cost ratio of 4.59 whereas, gross return for transplanted paddy was 87000 INR/ha preceding a net profit of 69200 INR/ha and benefit cost (B:C) ratio of 3.89. Data on drudgery aspects victuals that direct sowing of seed resulting in expected outcome of the technology as low draft requirement, labor saving, natural resource conservation, better output/profits and less occupational health hazards.

NTRODUCTION Paddy is one of the important crops of the world and is grown between latitudes 450 N and 400 S (Mohanty et al., 2008). Paddy as a major staple food is vital for the nutrition of much of the population in Asia, as well as in Latin America and the Caribbean and in Africa; it is central to the food security of over half the world population. Developing countries account for 95 percent of the total production, with China and India alone responsible for nearly half of the world output (Crawford et al., 1998; FAO, 2001). Indeed, paddy availability and food security have long been synonymous in Asia. The India who had to beg with food bowl in the 1950-60’s to feed her teeming millions, has become the world’s second largest producer of paddy preceded only by China (Mohanty et al., 2008; http ref. retrieved on Nov. 2011). For about 65% of the people living in India, paddy is a staple food for them; therefore, paddy is essential to life in India. It is a part of nearly every meal, and it is grown on a majority of the rural farms. In India, paddy occupies about 41.85 million hectares, which is nearly 40 percent of the total cereals (FAOSTATS, 2010). Paddy fields are a common sight throughout India, be they be northern gangetic plains or southern peninsular plateaus. Paddy is cultivated at least twice a year in most parts of India, the two seasons being known as Rabi and Kharif respectively. The former cultivation is dependent on irrigation, while the latter depends on Monsoon. Uttarakhand is one of the states exporting Basmati paddy in the country. The success story is a vivid example of the contribution of science and technology advances in cropping systems, fertilizer responsive high yielding crops, expanding irrigation, land reclamation and selective mechanization (Vajpayee, 2004). In agriculture sector women play an important role by contributing as active labour workforce. According to FAOSTATS (2010) gender in the agricultural labour force suggests that women constitute over 32 percent of the total agricultural labour force in the world. The world wide food production contributed by women is 43.88 percent. In India women carry out as much as 80 percent of the work in paddy production (Singh and Tiwari, 2009). They are involved right from seeding, Intl. J. Agric: Res & Rev. Vol., 2 (4), 0000, 2012 transplanting, weeding, harvesting and processing to marketing of produce and buying the necessities of life. Women labour is exclusively used for transplanting, harvesting, stubble collection, threshing and winnowing. Sowing of paddy involves cleaning seeds for sowing, nursery sowing, nursery aftercare, seedling uprooting and transplanting solely performed by women. Transplanting of paddy in puddled fields is generally preferred over dry sowing of seeds due to severe problem of weeds. The raising of nursery and manual transplanting are both labour intensive and costly prepositions (Das, 2003). Conventional paddy cultivation involves transplanting of seedlings in puddled fields performed by labours predominantly by women labours. The activity of the transplanting seedlings in puddled fields carried out consists of bending and static posture for long duration of time leading to many occupational hazards (Singh and Tiwari, 2009). The adverse conditions of the process are adhered to higher labour requirement in peak season. Celebration dinner as ethnic social system involves money putting an economical and sociological burden on the farmer. As the activity is predominantly carried out by women, it results in physiological, economical and sociological overburden of work in season on women. Therefore, this equation of grain production and drudgery involved in work is confounded be the need for pragmatic approach to afford technologies for the farmers involved in transplanting of paddy. On-farm studies are cost effective, foster mutual learning between researchers and producers (Spaner et al., 2000; Wuest et al., 1999), and allow for inference of treatment effect without extrapolation (GotwayCrawford et al., 1997; Rzewnicki et al., 1988). The present study was carried out as On Farm Research (OFR) on manual drum seeder for seeding paddy versus conventional method of transplanting of paddy to afford a technology for drudgery reduction in transplanting paddy the area. It is a presumption that the study could generate philanthropy in Asia that supports paddy science and innovations for the benefit of the entire region. Figure 1. Seedlings of 45 days ready for transplanting MATERIALS AND METHODS Methodology The OFR is an indispensable tool for developing and validating farming technology (Atta-Krah, 1992) which is a research carried out on farmer's fields and in a farmer's environment which identifies four key elements: the farmer, the farmer's land, the farmer's involvement, and the farmer's environment. The study herein is in exploratory phase with a demonstrative objective which is the stage where a new system or concept such as drum seeder is introduced into a community. This allows the farmers to gain an accurate image and a practical understanding of the system. It begins with the identification of individual farmers within the community with whom the researchers work closely to put the system on the ground. During this phase, researchers' involvement is very high as the farmers’ perception of the system is almost negligible. Therefore, a single farmer was selected for the present study. Seeding Technique of paddy in Conventional method The fields are prepared by ploughing either by typically with simple plow drawn by buffalo/bullocks or tractor drawn mechanized equipments depending upon the geographical situations and availability of resources. Fertilizing (usually with dung or sewage), and smoothing (by dragging a log over them). The seedlings are started in seedling beds and, after 30 to 50 days (fig. 1), are transplanted by hand to the fields, which have been flooded by rain, river water or any other irrigation source. The seed rate of up to 55 kg/ha is used in this method but, it significantly varies with the area, variety and farmers’ practice of growing paddy in the locality. Ravishankar et al., (2006) also reported that under conventional method of planting, the seed rate ranged from 44 to 55 kg/ha with mean of 48 kg. The posture required is a bending posture throughout the transplanting carried out in the fields. The process is dominantly performed by women farmers or paid labourers in the area as depicted in the figure-2. Figure 2. Conventional method of transplanting paddy Intl. J. Agric: Res & Rev. Vol., 2 (4), 0000, 2012 Time line of drum seeders available in India There are many paddy seeders are available. Das, 2003 reported that advancement in paddy seeder has been evolved since 60’s, the era of the Green Revolution in India. Central Paddy Research Institute (CRRI), Cuttuck, India developed a two row cup feed type manually operated pregerminated paddy seed drill in 1968. A manually operated five row single drum seeder for sowing pregerminated paddy seeder was developed at CRRI in 1977-78. Indian Agriculture Research Institute (IARI), New Delhi, India developed a manually drawn pregerminated seed drill with roller metering system in the year 1984. A three row puddled seeder was developed at CRRI during 1996-97. Manually pulled eight row drum seeder for sowing pregerminated paddy seeder have also been developed at International Paddy Research Institute (IRRI) Phillipines, DRR, Hyderabad, India, Tamilnadu Agricultural University, Coimbatore, India, Andhra Pradesh Agricultural University, Hyderabad and Indian Institute of Technology, Kharagpur, India. A six row improved low cost manual drum seeder for sowing pregerminated paddy seeder has been developed at CRRI during the year 2000. Central Institute of Agriculture Engineering (CIAE) Bhopal, India developed a four row drum seeder for sowing pregerminated seeds under puddled conditions. We have selected the four row drum seeder developed by CIAE for the present study to enhance the paddy productivity and make its production process less tedious. Specifications of the drum seeder used are as following in Table 1: Table 1. Salient Specifications of the Drum Seeder S. No. Particulars Values 1 Overall dimension (lxwxh), mm 1555x880x605 2 Weight, kg 7.7 Seeding technique of paddy by the selected drum seeder For seeding by drum seeder the process of growing seedling is not required. The seeds are soaked in water for 24 hours followed by incubation in gunny bags and straw for 24-48 hours depending upon the weather temperature. The germination length Figure 3. Filling of pregerminated paddy seeds in drum seeder The machine is pulled by one farmer on well levelled puddled field after draining the standing water because standing water more than one cm depth disturbs the seeds sown in straight lines. The pregerminated paddy seeds are sown with the help of drum seeder in well levelled puddled field after draining the standing water. If there is more water than 1 cm then seed will float. Therefore, of seeds should not be more than 1-2 mm to avoid any mechanical injury of pregerminated seeds and also to ensure free flow of seeds in the drum seeder. The pregerminated free flowing clean paddy seeds are filled upto 50 percent depth in each seed box by opening the hinge cover (fig. 3). Then the covers are closed. Figure 4. Sowing of pregerminated paddy seeds using drum seeder if there is more standing water in the fields it is better to leave the fields for 1-2 days for settling of puddled soil. Covering the seeds below wet soil surface is not desirable as anaerobic condition gives less germination percent. The posture required is a standing posture throughout the seeding of pregerminated paddy seeds carried out in the fields as depicted in the figure-4. After sowing Intl. J. Agric: Res & Rev. Vol., 2 (4), 0000, 2012 the seeds bird watching should be done for one week to check damage by birds. A thin layer of irrigation water is maintained till the seeds germinate. Once the paddy plants grow up water depth of 5-8 cms is maintained to avoid weed growth (Das, 2003). RESULTS AND DISCUSSION The OFR was carried out on farmer's fields and in a farmer's environment which identifies four key elements: the farmer, the farmer's land, the farmer's involvement, and the farmer's environment. Therefore, the results are discussed here from the perspective of all the four elements of the research as following: The Farmer In OFR, it is essential to specify the type of farmer for which a particular intervention is aimed, whether for development or for testing. Here, we were tackling a problem of smallholder and medium farmers who could afford the essential inputs for the technology. The "type of farmer" issue is not linked only to resource base, but may also be linked to the production system. The study was carried out in a farmer community where crop production of paddy is important, so that the technology will be relevant. The central issue, therefore, was to define and select the type of farmer for which the technology to be tested was appropriate and relevant. The study was carried out on a farmer’s field who owns land and cultivates mainly paddy-wheat-sugarcane. The farmer selected for the study was having a problem of labour in peak season and also the women farmers who perform the transplanting of paddy complaint many health hazards and related problems viz, back pain, boils on legs, feet, hands, sun burn, snake bites, etc. related to their posture during transplanting paddy in the puddled fields. The Farmer's Land Any experiment carried out on a plot of land outside the experimental station could be described as off-station research, but not all such research qualifies as on-farm research. For research to be classified as on-farm, it should be carried out on a plot of land belonging to the farmer and within the farm environment of the farmer (Atta-Krah, 1992). The area of plot taken for the study was 0.25 ha at the farmer’s field and also a plot size of 0.25 was taken at the station to take care of the any errors and make the study comparable (table-3). The Farmer's Involvement The nature of farmers' involvement in any OFR activity is very important as it influences the interpretation of output and results obtained. The exact nature and degree of farmer involvement is determined by the objective of the OFR and the nature of the research in terms of components, systems, or technologies being assessed. The degree of farmer involvement also has an effect on the design of the experiment and the interpretation of results obtained. Here, in the present study the farmer’ involvement was · “active involvement - researcher controlled” so that farmer has close experience of the technology on the one hand and also the researcher could have demonstration of the technology on a best possible way. Therefore, all the farming operations were carried out by the farmer and his resources at his farm with the close monitoring of the researcher. The Farmer's Environment A field day at the time of crop at full bloom was organized to demonstrate the technology with in farmer’s community and also to compare the results with the results of plot at the station. The field day was a gathering of all the stakeholders involved in crop production of paddy viz., farmers, community members, scientists and policy makers. It was done because the farmer does not live as an independent entity. He lives within a family structure, which in itself is embedded within a community structure. Thus, the farmer's input, assessment, and eventual adoption of a system will have to be viewed and assessed within the framework of the community in which the farmer operates. It also catered on the aspect of the farmer's environment that farmers' fields may have many more problems associated with soil fertility and drainage than the research station fields where on-station experiments have been conducted. Farmers may also be practicing a much more complex cropping system than is used in on-station trials. Performance data of drum seeder used for seeding of pregerminated paddy Table 2 victuals performance data of drum seeder developed by CIAE Bhopal, India similar to a study reported by Singh et al., (2007). The amount of pregerminated seed required to fill the drum seeder is about 2.5 kg and of approximately 4.6 cm length. The drum seeder is 80 cm wide as per the ergonomic parameters suitable to the worker. Sinkage of the filled drum seeder in puddled fields Intl. J. Agric: Res & Rev. Vol., 2 (4), 0000, 2012 reported is 4.6 cm. The seed rate reported by Singh et al., 2007 for the seeder is 51.6 kg per hectare but the seed rate used in the study is 40 kg per hectare for a hybrid variety PSD-3 (table-3). When the worker return from the last end of the field to the next row a loss of 11 seconds of duration is reported in each consecutive row and it was found to be the same for the study, too. The optimum output of the drum seeder is reported is 917 m2/h. Table 2. Performance data of drum seeder used for seeding of pregerminated paddy S. No. Particulars Mean values A The Drum seeder 1 Sprouted seed fed per drum, kg 2.5 2 Sprout length, cm 4.6 3 Working width of machine, cm 80.0 4 Sinkage of machine in field, cm 4.6 5 Seed rate, kg/ha 51.6 6 Time loss/turn, s 11.0 2 7 Output, m / h 917 B The Man Power 1 Number of workers required 2 2 Sinkage of feet of subject in field, cm 7.5 3 Walking speed of subject, km/h 1.4 4 Heart rate during work, beats/min 144 5 Work pulse, beats/min 61 6 2 Cardiac cost, beats/m C The Crop 1 Row to row spacing, cm 20.0 2 Number of seeds/m length 39 3 Number of hills/m length 6.2 4 Number of seeds/ length 2 to 7 (4.8) 5 Distance between hills, cm 6.9 It is evident from the table 2 that two workers are required to operate the drum seeder while using the drum seeder for filling the pregerminated seeds in the seeder (fig. 3). Whereas, single worker can pull the drum seeder for seeding the pregerminated paddy in puddled fields (fig. 4). Sinkage of the feet of the worker while performing the activity in puddled fields reported is 7.5 cm. An average walking speed of subject by using the drum seeder is 1.4 km/h which is mandatory to maintain the appropriate distance between the rows or plant to plant distance. The data on physiological cost of the worker shows that while using the drum seeder heart rate is 144 beats/min as comparable to permissible heart rate of 148 beats/min, work pulse rate is 61 beats/min and cardiac cost is 8 beats/m2 which 8 is within the acceptable limits for performing the activity. In the table 2 it is reported that the crop grown after seeding the paddy by using drum seeder have row to row spacing of 20 cm. Whereas, on an average 39 seeds seeds/m in length are found. The average number of hills/m length and number of seeds/ m length were 6.2 and 2 to 7 (4.8), respectively. The mean value of distance between hills was 6.9 cm. Comparison on various parameters for conventional method of transplanting paddy Vs seeding of pregerminated seeds using drum seeder The data in table 3 depicts that the OFR was conducted at two different locations, the one was at the research station and another Intl. J. Agric: Res & Rev. Vol., 2 (4), 0000, 2012 was at the farmer’s field to get over any error due to economical, sociological, anthropological, geographical parameter. The soil type of both the location was loam or the same. The variety of paddy was a hybrid variety namely, Pant Sankar Dhan (PSD) 3 developed and recommended for the area by G.B. Pant University of Agriculture & Technology Pantnagar, India. Fertilizer dose of NPK was also the same for both the locations and both the methods of paddy production methods i.e. the conventional method and the drum seeded paddy production which was 150:60:40 collectively as basal and further doses. Date of sowing the paddy in conventional method elucidates that nursery has to be sown about one month in advance than the crop to be sown using drum seeder which results in more consumption of resources. The seed placement in the drum seeder is at the surface which is performed by the machine but, the placement of seedling in the conventional method is under the mud with the help of fingers and in bending position which stimulates the stress and several occupational health hazards related to the transplanting paddy. The labour requirement in sowing by drum seeder is reduced by 90 percent as compared to manual transplanting in the conventional method. Table 3.

No. 1 2 3 4 5 6 7 8 9 Particulars Location Soil type Variety Fertilizer (N:P:K) Date of sowing Seed rate, Kg/ha Plot size, ha Seed placement Labour requirement, man-hr/ha The table 4 delineates that the cost of operation for sowing paddy using drum seeder was INR 800 per ha as compared to INR 30000 per ha in conventional method. The cost of weeding and cost of irrigation in the field of drum seeded paddy and transplanted paddy were INR 700, 1500 and INR 5600, 4800 per ha respectively. Grain yield was 60 Q/ha for drum seeded paddy and 58 Q/ha for transplanted paddy which was not showing a wide difference but yes it was a measurable parameter. Gross return for drum seeded paddy was 90000 INR/ha leading to a net profit of Drum seeder Conventional method On farmer’s field and research farm Loam Loam PSD-3 PSD-3 150:60:40 150:60:40 18.06.09 09.07.09 40 55 0.25 0.25 seeds on the surface seedlings under the soil 8 30 73900 INR/ha and benefit cost ratio of 4.59 whereas, gross return for transplanted paddy was 87000 INR/ha preceding a net profit of 69200 INR/ha and benefit cost ratio of 3.89. Direct seeded paddy with drum seeder under puddled conditions gives increased grain yield by 38 percent as compared to line transplanting and also it furnishes highest net return and benefit cost ratio (Halder and Patra, 2007; Jagadeesha et al., 2009). The data renders a remarkable difference on economic parameters and pays back to the farmer economically. Table 4.

J. Agric: Res & Rev. Vol., 2 (4), 0000, 2012 CONCLUSIONS OFR has proved its value as a methodology to afford a technology for the farmers. The present study resulted in demonstration and extension of drum seeder as a drudgery reducing tool or technology in local farming communities. Following conclusions can be ascertained from the above study: Use of drum seeder helps in timely sowing of crop resulting in more yield Sowing by drum seeder saves costly seeds The drum seeder reduces labour requirement and cost of sowing Line sowing by drum seeder reduces weeding cost due to use of mechanical weeders with transplanting The crop matures one week early in drum seeded plots The net profit obtained by use of drum seeder is more than transplanting Expected outcome of the study are: Shift of work of women to men which reduces a work load of women in peak season Labour saving in transplanting paddy optimizes the economic as well as human resources Better economy and future can be predicted through the replacement of conventional method of transplanting paddy into the seeding of paddy by using drum seeder. Natural resource conservation is there because irrigation is completely deleted in the crop production process and also the technology of drum seeder avoids the utilization of natural resources for growing seedlings required in the conventional method. Instead of bending for longer hours during the whole process of transplanting paddy have its own health hazards on the human body and aggression of the health hazards increases by puddled fields and higher temperature of water in the fields. Use of drum seeder involves standing rather walking posture which is ergonomically better that static posture which leads to less occupational health hazard involved in seeding process of paddy. The On Farm Research thus undoubtedly resulted in reducing arduous work load of the work regardless of the fact that who is performing the activity whether male or female worker. In the study, however it was performed predominantly by female workers in conventional method but, when the new technology was introduced it was performed by male workers. The complete transition of the activity from one to another counterpart needs to be taken care of in other researches as it is a matter of debate and further research that why the new technology is adopted/ initiated by male members and not the female.
