Response of Rice Varieties to Different Levels of Irrigation Under Aerobic Condition

Résumé

The field experiment was conducted West Central Table Zone, Odisha during summer season of 2019 & 2020 to evaluate the effect of medium duration rice varieties with varying irrigation regimes under aerobic condition. The experiment was laid out in split plot design having four irrigation regimes (Irrigation at IW/CPE = 1.0, 1.5, 2.0, 2.5) in main plot treatments and four varieties (Naveen, MTU-1010, CR Dhan-201 and CR Dhan-204) in subplot treatments. The result showed that higher grain yield was recorded at IW/CPE = 2.5 (4.07 t/ha) ,which was significantly superior to rest of other irrigation regimes except IW/CPE = 2.0 ( 3.90 t/ha) that was at par with IW/CPE = 2.5 .Whereas, in case of cultivars, higher grain yield was obtained with CR-Dhan 201( 3.54 t/ha) which was significantly to rest of other cultivars except Naveen (3.30t/ha) which was at par with CR-Dhan 201.The FWUE at IW/CPE 1.5 ( 40.71kg/ ha-cm) was recorded higher which was at par with other irrigation regimes except IW/CPE 2.5. The higer B: C ratio (1.74) was observed at IW/CPE 2.0 and at par with IW/CPE 2.5 (1.73) and significantly to rest other irrigation regimes. Whereas in cultivars, FWUE of 41.60kg/ ha-cm and B:C ratio (1.62) were observed with CR Dhan 201 but it was significantly to rest of other cultivars. It may be concluded that rice grown under aerobic culture, variety ‘CR Dhan 201’ was found optimum as it has resulted in highest growth of aerobic rice and realizing higher productivity besides enhancing economically profitability at irrigation regimes at IW/CPE 2.0 in West Central Table Land Zone of Odisha under aerobic condition.
