Abstract

A field experiment was conducted at instructional farm of College of Agriculture, Bikaner, Rajasthan to study the effect of levels and scheduling of nitrogen application on N content and uptake of malt barley (Hordeum vulgare L.) as affected by sowing dates during winter seasons of 2005-06 and 2006-07. The experiment was laid out in the split plot design with four replications on loamy sand soil. The growing environments and nitrogen levels were in main plot and nitrogen scheduling in the sub-plots. The results showed that significantly higher nitrogen content at pre-anthesis, in grain and straw, nitrogen uptake by grain and straw and total uptake of malt barley was observed under normal sown condition compared to late sown condition on two years pooled basis. Further, application of increasing levels of nitrogen from 60 to 90 kg ha^-1 significantly enhanced nitrogen content at pre-anthesis, in grain and straw, nitrogen uptake by grain and straw and total uptake of malt barley. Scheduling of nitrogen at 1/3 as basal + 1/3 at I^st irrigation + 1/3 at II^nd irrigation brought a substantial improvement in nitrogen content at pre-anthesis, in grain and straw, nitrogen uptake by grain and straw and total uptake of malt barley.

Abstract

The field experiment was conducted to find out the effect of nitrogen levels and its split application on yield attributes, yield and economics of malt barley (Hordeum vulgare L.) under normal and late sown conditions during winter seasons of 2005-06 and 2006-07. The results showed that significantly higher effective tillers / m row, spike length, grains / spike, test weight, grain, straw and biological yield, harvest index and net returns of malt barley were observed under normal sown condition compared to late sown condition. Further, application of increasing levels of nitrogen from 60 to 90 kg ha^-1 significantly enhanced effective tillers / m row, spike length, grains / spike, test weight, grain, straw and biological yield, harvest index and net returns of malt barley. Scheduling of nitrogen at 1/3 as basal + 1/3 at I^st irrigation + 1/3 at II^nd irrigation brought a substantial improvement in above yield attributing characters and yields, harvest index and net returns of malt barley.
