Abstract:

A field experiment was conducted on aerobic rice (Oryza sativa) during summer seasons of 2013 and 2014 at Regional Research and Technology Transfer Station, Chiplima, Sambalpur, Odisha in order to determine the effect of irrigation and nitrogen levels on yield, field water use efficiency and economics of aerobic rice (cv:Apo). The treatments consisted of four irrigations (irrigations at 3, 5, 7 and 9days interval) in the main-plots and four levels of nitrogen (0, 40, 60 and 80 kg N ha-1) in the sub-plots. The results revealed that interaction of irrigation at 3 day interval with 80 kgN ha-1 gave the higher grain yield (4.23t/ha))which was at par with 5 day interval with 80 kgN ha-1 and significantly superior to other interaction of irrigation intervals with nitrogen levels. The interaction of irrigation regime at 5 days interval with application of nitrogen at 80 kg ha-1 produced the highest field water use efficiency (45.26 kg ha-cm-1). It was at par with irrigation regime at 7 days interval with crop receiving nitrogen at 80 kg ha-1 and significantly superior to other interaction between irrigation regimes with nitrogen levels. Thus, irrigation at 5 days interval with 80 kg N ha-1 produced economically higher grain yield(4.23t/ha) and field water use efficiency(45.26kg ha-cm-1) under aerobic rice.
