A field experiment was conducted at Coimbatore in South West monsoon 1978 to identify the shade tolerant soybean varieties under the sorghum based cropping systems Performance of sorghum (Co. 21) was found better in paired row system. Maximum sorghum grain yield of 4304 kg per he was recorded when grown with soybean, Application of 80 ko N per ha resulted in higher sorghum orain vield of 4356 ko per ha over 60 kg N per ha. Of the five soyhaan varistias tested viz UGM Ma. Ma. Cul 27/8 and Punjah-1 as intercrop, the last one was highly tolerant to different shade levels and performed well both in uniform row system and paired row system and was followed by UGM Intercrup yield of 335 and 202 kg per he was recorded by Punjab 1 and UGMse respectively. Leb lab Co 9 recorded a highest green pod yield of 1241 kg per ha at 80 kg N in uniform tow system Maximum net return of Rs. 2939/- and Rs. 2841/- per ha were realised when sorghum was grown with lab-lab and soybean Punjab-1.
