Effect of split doses and time of nitrogen application on growth, yield attributes and yield of direct sown rice in puddled soil

Abstract

The result showed that at harvest there was no significant difference between treatments suggesting that the plant height was made up by the nitrogen supplied at larer stages. The treatment receiving half nitrogen at active tillering and the other half at panicle initiation stage recorded the maximum panicles/m2. Nitrogen application at later stages especially giving half at panicle initiation has resulted in maximum panicle weight and 1000 grain weight. Skipping basal application of nitrogen and applying half at active tillering and the other half at panicle initiation stage has given the maximum grain yield of 4874 kg/ha.
