Description A field experiment entitled “Studies on clusterbean based intercropping system under rainfed conditions” was conducted during kharif 2011 at Dry land Agriculture Research Farm of CCS Haryana Agricultural University, Hisar. The experiment comprised of 11 treatments viz; sole crops of clusterbean, pearl millet and greengram and intercropping of pearl millet and greengram in 2:1 to 8:4 row ratios, was laid out in randomised block design with three replications. Based on the research investigation it was found that the intercropping of pearl millet and greengram significantly decreased plant height, dry matter, leaf area, number of pods per plant, grain, stover, and biological yields as well as gum yield of clusterbean. LAI except 60 DAS, LAD at 30-60 and 60-90 DAS, CGR and RGR at all the stages, number of grains per pod, test weight, harvest index and gum content in intercropping treatments and sole clusterbean were statistically similar. Leaf area, LAI and LAD of clusterbean increased appreciably up to 60 DAS and thereafter decreased whereas, peak values of CGR and RGR were obtained during 30-60 days period of growth.
Among intercrop row ratios, 2:1 and 4:2 intercropping of clusterbean - pearl millet produces taller plants of clusterbean, whereas, dry matter at all the stages, leaf area at 60 and 90 DAS, LAI at 60 DAS, LAD at 30-60 and 60-90 DAS was significantly more in 6:3 and 8:4 row ratio intercropping of clusterbean - greengram and 8:4 row ratio of clusterbean - pearl millet as compared to 2:1 and 4:2 row ratio intercropping of clusterbean - greengram. Dry matter, grain, stover and biological yields of both the intercrops decreased significantly as compared to their sole crops. Intercropping of pearl millet in clusterbean in 2:1 and 4:2 row ratios has higher transmission coefficient in clusterbean crop than other intercropping treatments. Whereas, intercropping of pearl millet and greengram in 8:4 and 6:3 row ratios has absorption coefficient similar to sole clusterbean. Intercropping of clusterbean - greengram and clusterbean – pearl millet in 8:4 row ratio was superior in respect of land equivalent yield, area x time equivalent ratio, crowding coefficient, aggressivity and competition ratio. Clusterbean equivalent yield, monetary advantage index, income equivalent ratio, gross returns, net returns and benefit-cost ratio were highest in 8:4 row ratio intercropping of clusterbean - greengram.
