Effect of various nitrogen levels and mulches on barley under rainfed condition

摘要

Experiment was conducted during rabi season of 2001 -02 on sandy loam soil of Iglas, Aligarh. The treatment comprised three levels of nitrogen (N_25, N_50 and N_75) and four types of mulches (no mulch, grass, straw and plastic mulch). The results revealed that the growth and yield attributing characters as well as grain, straw, total biomass and nitrogen harvest of barley crop increased significantly with increasing nitrogen application rates except number of filled grains/earhcad and 1000-grain weight. Marked improvement in growth, yield attributes and yields as well as nitrogen uptake was recorded with application of mulches. The plastic mulch proved superior over others'.
