Abstract

A field experiment was conducted at the Regional Research Technology and Transfer Station (RRTTS), Chiplima, Sambalpur, Odisha during summer season of 2019 & 2020 to evaluate performance of medium duration rice varieties with varying irrigation schedules under aerobic condition. The experiment was laid out in split-plot design with 3 replications and consisted of four irrigation schedules i.e. I1 = Irrigation at IW/CPE = 1.0, I2 = Irrigation at IW/CPE = 1.5, I3 = Irrigation at IW/CPE = 2.0, and I4 = Irrigation at IW/CPE = 2.5 in main plot treatments and four varieties i.e. V1 = Naveen, V2 = MTU-1010, V3= CR Dhan-201 and V4 = CR Dhan-204 in subplot treatments.

The result of pooled mean of both the years showed that higher grain yield was recorded at IW/CPE = 2.5 i.e. 4.07 t/ha , which was at par with IW/CPE = 2.0 (3.90 t/ha) and significantly superior to rest of other irrigation schedules. But in case of cultivars, higher grain yield was obtained with variety CR-Dhan 201(3.54 t/ha) which was at par with variety Naveen (3.30t/ha) and significantly superior to rest of other cultivars. The interaction of irrigation at IW/CPE 2.0 with variety CR Dhan 201 gave the highest grain yield (4.39t/ha) which was at par with irrigation at IW/CPE 2.5 with variety CR Dhan 201 (4.30 t/ha) and significantly superior to rest of other interactions. The interaction of irrigation schedules at IW/CPE 1.5 with Naveen variety produced the highest field water use efficiency (44.05 kg ha-cm-1) but it was at par with all irrigation schedules except at IW/CPE 2.5 with variety CR Dhan 201. Hence, it may be concluded that variety like CR Dhan 201 needs to be irrigated at IW/CPE 2.0 produced economically optimum yield and field water use efficiency on sandy loam soils of western region of Odisha under aerobic condition.
