Abstract

Field experiments were conducted in kharif and rabi, 1991-93 on a sandy loam soil at Vridhachalam, Tamil Nadu to test the effect of intercropping of green gram, black gram and sesamum at 4:1 in groundnut sown at 33, 42, 50 plants/m2. It was inferred that pod yield varied at different plant population of sole and intercropped groundnut. Economic analysis of the treatment. combinations indicated the possibility of obtaining higher monetary benefit by adoption of the groundnut + green gram intercropping. For this system, groundnut population is to be increased to 42 plants/m² than recommended population of 33 plants/m².
