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.

Abstract

A field experiment was conducted to study the effect of phosphorus levels (0, 10, 20 30 and 40 kg P₂O₅ ha^-1) and sulphur levels (0, 10, 20 and 30 kg S ha^-1) on economics of blond psyllium (Plantago ovata Forsk) and optimum doses of fertilizers. The results showed that application of phosphorus significantly increased the net returns and seed yield of blond psyllium up to 30 kg P₂O₅ ha^-1. Whereas, B:C ratio significantly increased up to 20 kg P₂O₅ ha^-1. Application of sulphur significantly increased the net returns, B:C ratio and seed yield up to 20 kg S ha^-1. A level of 37.17 kg P₂O₅ ha^-1 and 28.824 kg S ha^-1 were found optimum doses for grain yields of 1288.54 kg ha^-1 and 1260.115 kg ha^-1, respectively.

Abstract

An experiment was conducted during Rabi season of 2002-03 to study the effect of phosphorus and sulphur fertilization on growth and quality of blond psyllium. The results showed that application of phosphorus up to 20 kg P₂O₅ ha^-1 wassignificantly increased the number of tillers per plant, plant height and leaf area index, whereas, dry matter at harvest and husk recovery significantly increased up to 30 kg P₂O₅ ha^-1 and all the levels of phosphorus, remained at par with each other in respect to protein concentration in blond psyllium grain. Also significant improvement in growth parameter viz., the number of tillers per plant, plant height, dry matter at harvest leaf area index and husk recovery of blond psyllium were also observed with the application of sulphur up to 20 kg S ha^-1.
