Abstract

An experiment was conducted during Rabi season of 2003-04 to study the effect of phosphorus, PSB and zinc on growth and quality of isabgol. The results showed that application of phosphorus up to 20 kg P₂O₅ ha^-1 significantly increased the plant height, number of tillers per plant; dry matter accumulation at harvest, protein concentration is seed and husk recovery. The inoculation of seed with PSB significantly enhanced the plant height, number of tiller per plant, dry matter accumulation at harvest, protein concentration in seed and husk recovery over uninoculated control. Also significant improvement in growth parameter viz., the plant height, number of tillers per plant, dry matter accumulation at harvest, protein concentration in seed and husk recovery were also observed with the application of zinc up to 5.0 kg ha-1.

Abstract

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 I^st irrigation + 1/3 at II^nd 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.

Abstract

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 I^st irrigation +1/3 at II^nd 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 I^st irrigation, 2/3 at basal +1/3 at I^st irrigation, 3/4 at basal +1/4 at I^st 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.

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 yield and economics of blond psyllium (Plantago ovata Forsk). The results showed that application of phosphorus significantly increased the spikes per plant, seed and biological yields of blond psyllium up to 30 kg P₂O₅ ha^-1, however, spike length, grains per spike, test weight and straw yield were significantly increased up to 20 kg P₂O₅ ha^-1. Application of sulphur significantly increased the grains per spike, seed, straw and biological yields up to 20 kg S ha-1, however, spikes per plant significantly increased up to 30 kg S ha^-1 and spike length up to 10 kg S ha^-1.

Abstract

An experiment conducted during Rabi season of 2002-03 to study the effect of phosphorus and sulphur on content and uptake of blond psyllium. Result revealed that all the phosphorus levels remained at par with each other in respect to nitrogen content in grain and straw. Application of phosphorus significantly increased phosphorus and sulphur content in grain and straw and nitrogen uptake by straw up to 20 kg P₂O₅ ha^-1 whereas, nitrogen uptake by grain, phosphorus and sulphur uptake by grain and straw and total nitrogen, phosphorus and sulphur uptake up to 30 kg P₂O₅ ha^-1. Application of sulphur significantly increased phosphorus and sulphur content in grain and straw and nitrogen and phosphorus uptake by grain and straw, total nitrogen uptake and sulphur uptake by straw up to 20 kg S ha^-1, whereas, total phosphorus and sulphur uptake by grain up to 30 kg P₂O₅ ha^-1.
