Effects of Bed and Furrow Irrigation System on the Growth, Production and Water use Efficiency of Lowland Rice Machungo C, Wanjogu R.K, Owilla, B , Njoka, J.J Anzwa, M. NIB RESEARCH WORKSHOP 13th & 14th June INTRODUCTION Water shortage in has necessitated the development of efficient water use methods for growing major crops. In traditional agronomic and water use practices (Irrigated puddled paddy fields), the farmers apply much more water for paddy crop than the actual requirements. INTRODUCTION Growing paddy on beds and furrows is an alternate, which utilizes much less water. In Pakistan water efficiency of rice under bed and furrow systems increased to 0.39 kg/m3 of water compared to 0.20 kg/m3commonly obtained under the traditional flood irrigation method Rice seedlings transplanted on beds and furrows Rice paddy growing on beds and furrows OBJECTIVE Determine the effects of bed and furrow irrigation system on growth, production and water use efficiency of lowland rice. Specific Objectives Determine the effect of bed and furrow irrigation system on growth and yield of lowland rice Determine the WUE of the bed and furrow irrigation system for lowland rice Optimize the design of bed and furrow method of irrigation to maximize, water saving and crop yield Treatments Description (Bed & Furrow Number of rows Configuration) T1 Bed 75cm and furrow 75 cm with Four rows on bed depth of 20 cm T2 Bed 75 cm and furrow of 38 cm with Four rows on bed depth of 20 cm T3 T4 Bed 75cm and furrow 38 cm with Two rows on bed depth of 20 cm Two rows on middle furrows Rice: Flooded Basin: Traditional transplanting on puddled soil (Control) 8 METHODOLOGY Varieties NERICA 4, Bas 370 and IR 2793 Factorial Split Experiment plot RCBD Design Main plot Variety – Sub plot Spacing – Sub- sub plot Factor Crop Management- As per recommended practice 9 Data Collection Growth Plant height Tiller counts Yield 28, 42, 56 , 70 & 84DAS parameters Tiller counts at harvest – PT, NPT & TT Panicle data- FG, SG, TG & Sterility 1000 grain weight Yield Kg/Ha Data Collection Weeds Total, Grass, Broadleaf, Sedges Volume of water delivered to each plot/irrigation Rate of infiltration Rainfall Depth data of water RESULTS Bed (75)furrow(75) Bed (75)furrow(38) Bed (75)furrow(38)- 2 rows Basin Plant Height (cm) 140 120 NERICA 4 100 80 60 40 20 0 28 42 56 Days After Sowing 70 84 Number of tillers/plant Bed (75)furrow(75) Bed (75)furrow(38) Bed (75)furrow(38)- 2 rows Basin 40 35 30 NERICA 4 25 20 15 10 5 0 28 42 56 Days After Sowing 70 84 Bed (75)furrow(75) Bed (75)furrow(38)- 2 rows Bed (75)furrow(38) Basin Plant Height (cm) 140 120 BASMATI 370 100 80 60 40 20 0 28 42 56 70 Days After Sowing 84 Bed (75)furrow(75) Bed (75)furrow(38)- 2 rows Bed (75)furrow(38) Basin Number of tillers/Plant 50 BASMATI 370 40 30 20 10 0 28 42 56 70 Days After Sowing 84 Bed (75)furrow(75) Bed (75)furrow(38) Bed (75)furrow(38)- 2 rows Basin Plant Height (cm) 70 60 IR 2793 50 40 30 20 10 0 28 42 56 70 Days After Sowing 84 Number of tillers/plant Bed (75)furrow(75) Bed (75)furrow(38) Bed (75)furrow(38)- 2 rows Basin 60 50 IR 2793 40 30 20 10 0 28 42 56 Days After Sowing 70 84 300 Total Grass Broadleaf Sedges No. of weeds/M2 250 NERICA 4 200 150 100 50 0 Bed (75)furrow(75) Bed (75)furrow(38) Bed (75)furrow(38)- 2 rows Irrigation Method Basin 300 Total Grass Broadleaf Sedges 250 Number of weeds/M2 BASMATI 370 200 150 100 50 0 Bed (75)furrow(75) Bed Bed (75)furrow(38) (75)furrow(38)- 2 rows Irrigation Method Basin 300 Total Grass Broadleaf Number of weeds/M2 250 Sedges IR 2793 200 150 100 50 0 Bed (75)furrow(75) Bed Bed (75)furrow(38) (75)furrow(38)- 2 rows Irrigation Method Basin 80 NERICA 4 % Crop Water Use Efficiency 70 60 50 40 30 20 10 0 Bed (75)furrow(75) Bed Bed (75)furrow(38) (75)furrow(38)- 2 rows Irrigation Method Basin % Crop Water Use Efficiency 80 BASMAI 370 70 60 50 40 30 20 10 0 Bed (75)furrow(75) Bed (75)furrow(38) Bed (75)furrow(38)- 2 rows Irrigation Method Basin 70 IR 2793 60 % CWUE 50 40 30 20 10 0 Bed (75)furrow(75) Bed (75)furrow(38) Bed (75)furrow(38)- 2 rows Irrigation Method Basin 20 PT NPT NERICA 4 Number of tillers 16 12 8 4 0 Bed (75)furrow(75) Bed (75)furrow(38) Bed (75)furrow(38)- 2 rows Irrigation Method Basin 40 PT 35 NPT Basmati 370 Number of tillers 30 25 20 15 10 5 0 Bed (75)furrow(75) Bed Bed (75)furrow(38) (75)furrow(38)2 rows Irrigation Method Basin 35 PT Number of Tillers 30 NPT IR 2793 25 20 15 10 5 0 Bed (75)furrow(75) Bed Bed (75)furrow(38) (75)furrow(38)- 2 rows Irrigation Method Basin 16 14 NERICA 4 12 % Sterility 10 8 6 4 2 0 Bed (75)furrow(75) Bed Bed (75)furrow(38) (75)furrow(38)- 2 rows Irrigation method Basin 20 BASMATI 370 % Sterility 16 12 8 4 0 Bed (75)furrow(75) Bed (75)furrow(38) Bed (75)furrow(38)- 2 rows Irrigation Method Basin IR 2793 16 14 % Sterillty 12 10 8 6 4 2 0 Bed (75)furrow(75) Bed (75)furrow(38) Bed (75)furrow(38)- 2 rows Irrigation Method Basin 3500 3000 NERICA 4 Yield Kg/Ha 2500 2000 1500 1000 500 0 Bed (75)furrow(75) Bed Bed (75)furrow(38) (75)furrow(38)- 2 rows Irrigation Method Basin 1750 1700 BASMATI 370 1650 Yield Kg/Ha 1600 1550 1500 1450 1400 1350 1300 Bed (75)furrow(75) Bed Bed (75)furrow(38) (75)furrow(38)- 2 rows Irrigation Method Basin 2500 IR 2793 Yield Kg/Ha 2000 1500 1000 500 0 Bed (75)furrow(75) Bed (75)furrow(38) Bed (75)furrow(38)- 2 rows Irrigation Method Basin CONCLUSION The irrigation method did not have a significant effect on growth measured height and number of tillers over time. Weed density was significantly higher in the bed and furrow systems compared to the basin Crop water use efficiency higher in the bed furrow system vs. the basin. CONCLUSION The yields did not differ significantly between the f bed furrow system and the basin for the lowland varieties (Basmati 370 & IR2793. The bed furrow systems evaluated did not show significant differences for most parameters evaluated. CONCLUSION To overcome the scarcity of irrigation water and generate higher crop yield, the bed and furrow method could be recommended for paddy cultivation CONCLUSION However, more field investigations are required To refine to the configurations of bed and furrows and rice planting system To quantify amount of water saved Cost benefit analysis – Establish benefits of Bed and furrow system vs Basin.
