Abstract

A field experiment was conducted during the winter (rabi) season of 1998–99 and 1999–2000 at Hisar, to determine the impact of N fertilizer applied at different growth stages, with and without vermicompost on yield components, grain yield and malting quality of barley (Hordeum vulgare L., s.l.) in the first trial and to study the effect of different levels of nitrogen and phosphorus with and without vermicompost on yield and nutrient uptake by barley in the second. Nitrogen application significantly enhanced the grain and straw yields up to 90 kg N/ha. All the yield components, grain yield and nutrient uptake attained their maximum value with 10 tonnes/ha vermicompost. The grain and malt quality of barley was also influenced significantly with the application of vermicompost and nitrogen levels. The result indicated that N fertilizer strategies for malting barley should ensure relatively small amount of available one-third N at sowing for crop establishment and initial tiller development. Additional one-third N would then be applied at first irrigation (35 days after sowing) and one-third N at flowering (70 days). The highest grain yield and nutrient uptake were recorded with N90P30 level of fertility.
