ABSTRACT
A field experiment was conducted at agronomy experimental unit, University of Agricultural Sciences, Bangalore during Kharif 2001 to evaluate fingermillet and castor intercropping. The experimental design followed was split plot repeated thrice. Intercropping systems were in main plots and fertility levels as sub plots. There are four intercropping systems fingermillet + pigeonpea (8:2), fingermillet + Akkadi (unproportion mixture of cowpea, sorghum, niger, avare) (5:1), fingermillet + castor (4:1) and 8:1 compared with sole fingermillet and castor. Sub plots nutrition levels includes recommended fertilizers (50:40:25 kg NPK/ha), recommended fertilizers + poultry compost (@ 5 t/ha) and 50% recommended nitrogen through compost and rest of NPK through fertilizers. Biomass production, yield and economic advantage assessment indicated that intercropping systems superior over sole crops. Pigeonpea or castor as intercrops after every eight rows of fingermillet found to be advantageous than traditional Akkadi intercrops (5:1). Combined application of fertilizers and compost (@ 5t/ha) resulted in higher yield and economic returns.
