Experiment on “Effect of seed rate and nutrition on water use efficiency and yield of hydroponics maize fodder” was carried out at AICRP on Dry Land Agriculture, University of Agricultural Science, GKVK, Bengaluru during 2017-18. The experiment was laid with Completely Randomized Design having five repetitions with six seed rate treatments viz., 1.50, 1.75, 2.00, 2.25, 2.50 and 2.75 kg m-2. Seed rate with 2.75 kg m-2recorded significantly higher water use efficiency (612.22 kg m-3) as compared to 1.50 kg m-2 (379.01kg m-3) and it was on par with 2.50 kg m-2(599.63 kg m-3). Nutritional experiment was laid in Completely Randomized Design with factorial concept with three repetitions each using four different nutrient sources(urea @ 1 %, MOP @ 1 %, urea and MOP each @ 1 % and 19:19:19 @ 1 %) and two levels of spray schedules (one spray at 6 DAS and two sprays at 3 and 10 DAS) and no spray was taken as control. In nutrient study 2.50 kg m-2 was taken as standard seed rate and Significantly higher water use efficiency was recorded with two sprays of urea and MOP each @ 1 per cent at 3 and 10 DAS (744.46kg m-3) as compared to control (598.96kg m-3).
A field experiment was conducted at Zonal Agricultural Research Station, V. C. Farm, Mandya, to study the effect of irrigation management practices and rice establishment methods on growth and yield of rice (Oryza sativa L.) during Kharif 2018. The experiment was laid out in split plot design with three main plot irrigation methods and five sub plot rice establishment methods. The combination of 15 treatments was replicated thrice. The results revealed significantly higher leaf area (920.61 cm2 hill-1), dry matter production (70.82 g hill-1) at harvest, net returns (42,495 Rs. ha-1) and B:C ratio (2.00) in alternate wetting and drying up to PI followed by flooding 3 ± 2 cm after PI method of irrigation. While among establishment methods, manual transplanting recorded significantly higher grain yield (5253 kg ha-1). Interaction between alternate wetting and drying up to PI followed by flooding 3 ± 2 cm after PI and mechanical transplanting recorded higher gross returns (99,377 Rs. ha-1), net returns (55,112 Rs. ha-1) and B:C ratio (2.25).
