Effect of Irrigation, Varieties and Nutrient Management for Improving the Productivity of Rice Fallo

Field experiments were administered at Tamil Nadu Rice Research Institute, Aduthurai during edible grain fallow season 2013 and 2014 to judge the effect of irrigation, types and nutrient administration for maximizing yield in rice fallow dark gram. The experiments were planned in split plot design with three replications. The main plot situations comprised of watering (one additional irrigation at 25 DAS and no watering) and black grandam varieties (ADT 3 and LBG 752) and food management practices (Foliar spray of 2% DAP on 30 and 45 DAS, Pulse question 5 kg/ha on 35 DAS and 1% 19:19:19 complex on 25 DAS fb 2% urea on 35 DAS, 2% urea phosphate on 35-40 DAS, soil application of DAP at 50 kg/ha to the standing paddy concurrently with an activity of last irrigation and control) were assigned to substitute plots. The results revealed that the edible grain fallow dirty gram likely with individual supplemental watering at 25 DAS recorded taller growth, yield attributes, yield, net return and BC percentage than no irrigation. Black grandam variety LBG 752 recorded higher plant height distinguished to ADT 3. However, yield attributes and yield were higher accompanying ADT 3 whereas it was corresponding with LBG 752. ADT 3 recorded the highest net return and BC percentage than LBG 752. Foliar application of differing nutrient beginnings performed likewise with respect to tumor, yield attributes and yield of black grandam. However, soil application of DAP 50 kg /ha during last watering to the standing paddy recorded larger net return and BC ratio trailed by foliar application of 2% DAP on 30 and 45 DAS. Hence, angry gram assortment ADT 3 or LBG 752 given accompanying one additional irrigation at 25 DAS trailed by foliar application of 2% DAP at 30 and 45 DAS or soil use of DAP at 50 kg/ha to the standing paddy at the time of last watering could be recommended for seizing higher output under rice inactive condition.
