Dry matter production and nutrient uptake of succeeding groundnut (Arachis hypogea L.) as effected by cumulative residual effect of crop residue incorporation and nitrogen management practices.

摘要

Field experiment was conducted in the wetland farm of for during 2002-2003 and 2003-2004 to investigate the cumulative residual effect of incorporated crop residues and different nitrogen management practices applied to preceding lowland rice on the performance of succeeding groundnut. Incorporation of fieldbean crop residues and supply of 100 per cent N through FYM to rice was superior to any other crop residue incorporation and nitrogen management practices adopted. Similar magnitude of performance of groundnut was noticed with the combination of fieldbean crop residue incorporation and supply of 50 per cent nitrogen each through fertilizer and FYM to preceding rice.
