The effects of interval irrigation and nutrient management on rice yield

In order to study the effect of irrigation interval and different levels of N application on paddy soils a study was carrired out in a CRBD in 2005-7 with 3 replications. Irrigation managements with 3 levels were the main plots and 4 levels of N application were the sub-plots. The result showed that...

Summary:In order to study the effect of irrigation interval and different levels of N application on paddy soils a study was carrired out in a CRBD in 2005-7 with 3 replications. Irrigation managements with 3 levels were the main plots and 4 levels of N application were the sub-plots. The result showed that differences between yields in 8-day irrigation interval and control was not significant . The differences between yield in treatments of 60 and 75 kg ha -1 of N were not siginificant. Over all, the irrigation wiyh 8 day interval and application of 60 kg N gave the hieghest water productivity .
