Yield and economics of maize- sunflower cowpea cropping system as influenced by phosphorus management practices

Abstract

Field experiments were carried out during 1997-98 and 1998-99 at Tamil Nadu Agricultural University, Coimbatore, to study the effect of phosphorus sources and levels in a maize sunflower- fodder cowpea croppmg system. The maize grain equivalent yield MGE increased when SSP was applied with microbial inoculants with 75 % recommended level of P2O2 when applied to all the three crops in the system. The economics of the system revealed that SSP with microbial inoculants, P2O2 at 75% recommended level, P2O2 for maize and sunflower and skipping P2O2 for fodder cowpea was found to be economical.

Keywords: Phosphorus, Maize Grain Equivalent, Cropping system, Economics.
