Abstract

                                Field experiments were conducted to study the impact of integrated approach on weed flora, weed dry matter production and the yield of pigeonpea + black gram intercropping systems at the National Pulses Research Centre, Vamban during the rainy seasons (kharif) of 1994 and 1995. Pre-emergence application of fluchloralin 1 kg/ha followed by hand weeding on 25 days after sowing offered good scope for significant reduction in weed density and weed dry matter production and registered significantly higher yield in main crop as well as inter crops.

Key words : Fluchloralin, pigeonpea, black gram, weed, intercrop
