 ABSTRACT

The experiment was conducted during kharif season of 2019 at All India Co-ordinated Research Project on Sorghum, Krishi Vigyan Kendra, Chamarajanagar District, Karnataka. To evaluate the sorghum based legume intercropping system. The experiment consists of fourteen treatment combination with different legumes viz.,Redgram, Greengram, Blackgram, Cowpea and Field bean in different row ratio of 2:1, 4:1 and 4:2. It was laidout in Randomized Complete  Block Design and replicated thrice. The results revealed that there was significant increase in sorghum grain yield (1593 kg/ha), Land equivalent ratio (1.35) and Area Time Equivalent ratio(1.32) with sorghum+blackgram(4:2). While higher gross returns (Rs. 44,213 ha), net returns(Rs. 27,434 ha) and Benefit: Cost ratio (2.64) was found with sorghum + green gram(4:2). Increase in Sorghum Equivalent Yield (2,544 kg/ha) was recorded with sorghum+redgram(2:1). From the results it was confirmed that sorghum+ blackgram or sorghum+green gram in 4: 2 row proportion was better in terms of yield and economics compared to the other treatments.

Keywords: Legume, Blackgram, Yield, LER, B:C ratio and SEY
