dc.description.abstractTransplanted rice is the traditional rice cultivation consumes more water, which threatens the sustainability of rice production. Thus, there is a need to find out the alternate means of rice cultivation to save water and other inputs. A field experiment was conducted during the summer seasons of 2019 and 2020 in the West Central Table Zone of Odisha to evaluate the efficacy of medium-duration rice varieties under varying irrigation regimes in aerobic conditions. The experiment followed a split-plot design with four irrigation regimes ( IW/CPE ratios of 1.0, 1.5, 2.0, and 2.5) as main plots and four rice varieties (Naveen, MTU-1010, CR Dhan-201, and CR Dhan-204) as subplots. The irrigation regime at IW/CPE = 2.5 recorded the maximum grain yield of 4.07 t/ha, which was significantly superior to the other irrigation regimes, but statistically at par with IW/CPE = 2.0 (3.90 t/ha). Among the cultivars, the variety CR Dhan-201 produced the higher grain yield (3.54 t/ha), which was significantly higher than the other varieties, but at par with Naveen (3.30 t/ha). Maximum nutrient uptake was observed at the IW/CPE = 2.5 irrigation level, with uptake values of 80.07 kg N/ha, 36.70 kg P/ha, and 124.4 kg K/ha, all of which were significantly superior to other irrigation regimes. Similarly, the variety CR Dhan-201 exhibited the higher nutrient uptake, recording 65.41 kg N/ha, 30.49 kg P/ha, and 104.8 kg K/ha, significantly superior than the other cultivars/varieties. The maximum FWUE was observed under IW/CPE = 1.5, with a value of 40.71 kg/ha-cm, which was at par with other irrigation regimes except IW/CPE 2.5 whereas, B: C ratio (1.74) was observed with irrigation at IW/CPE 2.0 which was at par with IW/CPE 2.5 (1.73)and significantly superior to other irrigation regimes. Among the varieties, CR Dhan-201 recorded the higher B:C ratio of 1.62 & higher FWUE of 41.60 kg/ha-cm which was significantly superior to the rest other cultivars.en_US
