Abstract

An experiment was conducted during September to December 1986 (rabi season) and February to May 1987 (summer season) on sandy loam and clay loam soils respectively under irrigation at the Tamil Nadu Agricultural University, Coimbatore, to find out the effect of N and Rhizobium inoculations in sorghum-soybean intercropping. It was inferred that the sorghum Co26 in double paired row intercropped with soybean Col at 50 per cent of the recommended level of N (45 kg N ha') in combination with the indigenous Rhizobial strain, Rhizobium japonicum soybean 53 gave the highest grain yield of sorghum and soybean with a saving of 45 kg N ha¹.
