Abstract

An investigation was taken up during rabi (November-May ) season (2001-2002) to study
the effect of nursery fertilization with phosphorus sown at different dates on growth of nursery
and on the crop in the main field. At low temperatures, application of 2.0 kg P2O5/100m2 resulted
in significantly higher root length, shoot length, dry matter, NPK uptake and establishment
percentage in the main field which ultimately resulted in higher NPK uptake and increased
grain and straw yields over 0.5 kg P2O5/100m2
