Abstract

                                Two field experiments were conducted at Tamil Nadu Agricultural University, Coimbatore during rabi. 1994 and Kharif, 1995 to investigate the weed suppressing effect of green manures grown with maize as dual crop. The results revealed that raising cowpea as a dual crop with maize at a spacing of 60 x 20 cm not only suppresses the weed growth but also supplies nutrient to the crop, resulting in highest grain yield, (62 q/ha) net return (Rs. 12,006/ha) and BC ratio (2.06) compared to 43.6 q/ha, Rs. 6376/- and 1.55 respectively under sole cropping of maize.

Key words : Green manure, Dual cropping
