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 Ist irrigation + 1/3 at IInd 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.Keywords

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 Ist irrigation + 1/3 at IInd irrigation brought a substantial improvement in above yield attributing characters and yields, harvest index and net returns of malt barley.Keywords

The field experiment was conducted to find out the effect of levels and scheduling of nitrogen application on growth parameters of malt barley (Hordeum vulgare L.) as affected by sowing dates during winter seasons of 2005-06 and 2006-07. The results showed that significantly higher growth attributing characters viz., leaf weight, stem weight, dry matter accumulation and heat unit efficiency of malt barley at 60 DAS, anthesis, 10 days after anthesis and at physiological maturity and spike weight only at anthesis, 10 days after anthesis and at physiological maturity of malt barley was 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 plant height, total number of tillers, leaf weight, stem weight, dry matter accumulation and heat unit efficiency of malt barley at 60 DAS, anthesis, 10 days after anthesis and at physiological maturity and spike weight only at anthesis, 10 days after anthesis and at physiological maturity of malt barley. Scheduling of nitrogen at 1/3 as basal + 1/3 at Ist irrigation + 1/3 at IInd irrigation brought a substantial improvement in growth attributing characters viz., leaf weight, stem weight, spike weight, dry matter accumulation and heat unit efficiency at anthesis, 10 days after anthesis and at physiological maturity of malt barley.Keywords

A field experiment was conducted to evaluate the effect of nitrogen levels and its split application on growth, yield and quality of malt barley (Hordeum vulgare L.) under normal and late sown conditions during winter seasons of 2005-06 and 2006-07 at Agronomy Farm, College of Agriculture,Bikaner. The results showed that significantly higher different quality parameters like as screening percentage, grain protein concentration and husk content of malt barley was observed under late sown condition compared to normal sown condition.While, plumpness and average grain weight was significantly higher under normal sown. Further, application of increasing levels of nitrogen from 60 to 90 kg ha-1 significantly enhanced grain protein concentration, average grain weight and alpha amylase activity of malt barley. While, starch concentration and husk content was significantly higher under 60 kg N ha-1. Scheduling of nitrogen at 1/3 as basal +1/3 at Ist irrigation +1/3 at IInd irrigation brought a substantial improvement in grain protein concentration, plumpness and alpha amylase activity while starch concentration and husk content was decreased as compared to two splits viz.,½ at basal + ½ at Ist irrigation, 2/3 at basal +1/3 at Ist irrigation, 3/4 at basal +1/4 at Ist irrigation and full basal. Scheduling of N in three equal splits affect the quality of malt barley grains. The prescribed limit as per Indian standards in North-Western Rajasthan conditions.Keywords
