Effect of row ratios and integrated nitrogen management on the productivity and economics of Cenchrus ciliaris and moth bean (Phaseolus aconitifolius) intercropping system in semi-arid conditions of Rajasthan

A field experiment was conducted during kharif season of 2005 and 2006 at farmer's field to assess the production potential and economics of intercropping of Anjan grass (Cenchrus ciliaris) and moth bean (Phaseolus aconitifolius) under semi-arid conditions of Rajasthan. Intercropping of C. ciliaris and moth bean in 2:1 row ratio during 2005 and 2006 recorded the highest yield for dry fodder (33.17 and 38.42 q/ha) and seed of C. ciliaris (1.39 and 1.42 q/ha), whereas produced highest crude protein yield (393.29 and 418.04 kg/ha) with 1:2 row ratio of C. ciliaris and moth bean respectively. Maximum net return during 2005 and 2006 (Rs 24,764 and 25,798 /ha) and benefit: cost ratio (1.85 and 1.90) was observed in 2:1 row ratio. Among nitrogen (N) sources during 2005 and 2006, maximum dry fodder (34.40 and 39.44 q/ ha), seed production in C. ciliaris (1.43 and 1.47 q/ha) and moth bean (6.68 and 7.04 q/ha), crude protein yield (423.40 and 446.02 kg /ha), maximum net return (Rs 25755 and 27654 /ha) and benefit: cost ratio (1.83 and 1.99) were recorded with the application of 50% N through inorganic source + 25% through sheep manure + 25% vermicompost as compared to other treatment combinations. The productivity of C. ciliaris and moth bean intercropping row ratio in 2:1 increased remarkably with judicious use of organic and inorganic fertilizers under semi-arid conditions of Rajasthan.
