Abstract

Field investigations conducted at CCS Haryana Agricultural University, Hisar, India during 2007–08 and 2008–09 revealed that both the doses and sources of nutrients increased weed emergence in pearl millet-wheat cropping system. The increase in fertilizer dose decreased weed emergence and manures as source of nutrients increased weed emergence during both the crops. The increase in fertilizer dose increased pearl millet, wheat and wheat equivalent yield and highest yield was recorded with the application of 50% recommended NPK dose through fertilizers+50% N through farm yard manure in kharif and 100% recommended NPK dose through fertilizers in rabi season during both the years and it was closely followed by the treatment where recommended dose during both the years was applied through chemical fertilizers. Among the organic sources, the increase in yield was highest with farm yard manure (FYM) and it was followed by green manure and wheat straw in descending order of magnitude.
