Abstract:
A Field experiment was conducted at Kallampuli village, Kadayanallur block, Tenkasi District during Kharif season (May to October) 2020 to evaluate the effect of different intercropping systems on yield attributes of cotton. The intercrops included in the investigation were T₁-Cotton alone, T₂-Cotton+Blackgram, T₃-Cotton+Greengram, T₄-Cotton+Cowpea, T₅-Cotton+Tomato, T₆-Cotton+Brinjal, T₇-Cotton+Coriander, T₈-Cotton+Sunflower, T₉-Cotton+Sesame. Among the various intercrops evaluated, the higher yield components of cotton viz., number of monopodial branches plant^-1, number of sympodial branches plant^-1, number of squares plant^-1, number of bolls plant^-1, boll weight of cotton were noticed in Cotton+Blackgram, and these parameters significantly increase the seed cotton yield of cotton. This was followed by Cotton+Greengram. This was statistically on par with Cotton+Cowpea intercropping system. The least values for all the yield parameters were registered with cotton+sunflower intercropping system.
