Abstract: PERFORMANCE OF CASTOR (Ricinus communis L.) BASED INTERCROPPING SYSTEMS IN NORTH EASTERN DRY ZONE OF KARNATAKA Mahantesh Chougule 2014 B. M. Chittapur Major advisor ABSTRACT A field experiment was conducted to investigate the ‘Performance of castor (Ricinus communis L.) based intercropping systems in North Eastern dry Zone of Karnataka’ during 2013 at the Agricultural College Farm, Raichur using Randomized Complete Block Design with 11 treatments replicated thrice. Treatments consisted of a sole crop and castor + intercrops [(two oilseeds viz., groundnut and sesame; two minor millets-pearlmillet and foxtailmillet and a grain legume- clusterbean at two row proportions (1:1 and 1:2)]. Castor + groundnut (1:1) intercropping system produced significantly higher castor seed yield (1100 kg ha-1) which was closely followed by castor + groundnut (1:2) and sole castor compared to other intercropping systems where in castor seed was significantly reduced. Further, castor + groundnut (1:2) also recorded significantly higher castor equivalent yield (1964 kg ha-1) and production efficiency (16.36 kg ha-1 day-1) besides higher protein (517 kg ha-1) and fat (915 kg ha-1) in seed followed by castor + groundnut (1:1). While, the maximum carbohydrate yield (943 kg ha-1) was observed with castor + pearlmillet (1:2) followed by castor + pearlmillet (1:1). Total output energy (96,300 MJ ha-1) and net energy (82,370 MJ ha-1) were maximum with castor + groundnut intercropping system in 1:2 row proportion followed by castor + groundnut (1:1) intercropping system while, output : input (7.86) and energy use efficiency (159.85 kg 1000 MJ-1) were maximum with castor + groundnut (1:1) closely followed by castor + groundnut (1:2). Better utilization of light, soil moisture and rain water use efficiency (3.79 kg m-3) were recorded castor + groundnut (1:2) followed by castor + groundnut (1:1). Significantly higher gross returns (` 81,050 ha-1), net returns (` 42,081 ha-1), B:C (1.08) and economic efficiency (` 350 ha-1 day-1) were obtained with castor + groundnut (1:2); castor + groundnut (1:1) was distant second yet superior to sole castor.
