STUDIES ON THE INTERCROPPING OF SORGHUM (Sorghum bicolor) REDGRAM (Cajanus cajan), GREENGRAM (Vigna radiata) AND SOYBEAN (Glycine max) WITH REFERENCE TO PLANT POPULATION

Abstract

Intercropping of greengram (S-9), sorghum (CSH 6). redgram (UPAS 120) and soybean (Bragg) with two plant populations for each component crop (50 and 100% of their normal population) in a paried row system was studied at Dryland Research area of Haryana Agricultural University, Hissar, during kharif 1979 and 1980. Intercropping, especially with sorghum reduced the grain yield of greegram. During normal year of rainfall (1979) there was no yield difference between 50 and 100 per cent plant population; In compartively dry year (1980), 100 per cent plant in intercropping gave higher yield. Sorghum as an intercrop reduced total dry matter production in greengram.
