Abstract

                                ABSTRACT Field investigations were carried out at the Agricultural Research Station, Kovilpatti during 1990-91 and 1991-92 to find out the effect of intercropping of black gram genotypes on the yields of Gossypium hirsutum and G.arboreum cotton varieties viz. MCU 10 and K 10 under rainfed vertisols. It was observed that cotton intercropped with black gram genotypes KBG 512 recorded a mean seed cotton yield of 602 kg/ha with MCU 10 and 1073 kg with K 10, respectively. Net monetary returns and LER were also higher when cotton was intercropped with black gram genotype KBG 512. The other black gram genotypes tested reduced the cotton yield in both the species of cotton varieties.

Key words : Black gram, Intercropping, Effect, Seed Cotton Yield
