| dc.description.abstract | The study was conducted to evaluate different irrigation scheduling techniques interims of yield and water productivity for pea crops by drip irrigation methods. The irrigation scheduling techniques were FAO CROPWAT model, Wetting Front Detector and Tensiometer. Field set up of the experiment was arranged by using RCBD statistical method. It had three treatments and three replications for each treatment to increase confidence and decrease error. After installation of the field using drip irrigation method, irrigation was done on the basis of daily evapotranspiration (ETO) for FAO, WFD and tensiometer techniques. The amount of water irrigated to the field in each irrigation scheduling was different. Pesticide and insecticide managements were performed throughout crop growth stages. During harvest (mid and late stages) yield were measured for each technique separately. Statistical analysis was performed using SPSS 16.0. The total water consumption during the irrigation season for FAO, WFD and TM were 467, 249 and 203 mm respectively. Here 47% of water was saved by WFD and 57 % by TM compared to FAO. The total irrigation water consumed by three techniques had a significant difference (p<0.05) with each other. The total yield obtained from FAO,WFD and TM were 3575kgha-1,4075kgha-1 and 2817kgha-1 respectively. This means that 31% and 12% yield difference were observed at WFD compared to TM and FAO respectively. The analysis showed that there were a significant difference (p<0.05) between WFD with TM but not at WFD with FAO and TM with FAO for crop yield obtained. The pea crop irrigation productivity was 0.77, 1.64 and 1.39 kgm-3 for FAO, WFD and TM irrigation scheduling techniques. In general the finding indicated that WFD irrigation scheduling technique was the best way for crop and water productivity for pea crop under drip irrigation method. | en_US |
