Abstract


A field experiment was conducted during kharif season of 2017 to evaluate the effect of nutrient management inpigeonpea and foxtail millet intercropping system under rainfed condition of northern transition zone of Karnataka. Two solecrops (pigeonpea and foxtail millet) with seven combinations of pigeonpea intercropping with foxtail millet and greengram werecompared under different nutrient levels. Results revealed that, sole pigeonpea recorded higher total dry matter production(318.5 g plant-1), leaf area (29.5 dm2 plant-1), leaf area index (1.23), primary branches (8.80) and higher grain yield of 1638 kg ha-1 wasrecorded, which was 2.5 % more than that of intercropping system. Among intercropping systems, pigeonpea (100 % RDF)+ foxtail millet (50 % RDF) recorded higher growth and yield parameters. Grain yield of 1598 kg ha-1 was recorded inpigeonpea, which was 23 per cent higher over other intercropping systems. Sole foxtail millet recorded higher number of tillersper meter row length (74.3), total dry matter production (36.2 g plant-1), grain yield (2744 kg ha-1), straw yield (2911 kg ha-1) andharvest index (0.49). Among intercropping systems, pigeonpea (125 % RDF) + foxtail millet (100 % RDF) recorded highergrowth and yield parameters of foxtail millet and grain yield (2301 kg ha-1), straw yield (2452 kg ha-1) and harvest index (0.48).Optimum pigeonpea equivalent yield (2423 kg ha-1), net returns (` 98,100 ha-1) and BC ratio (3.40) was obtained in pigeonpeawith 100 % RDF and foxtail millet with 50 % RDF.
