Assessment of yield advantages in intercropping system

Assessment of yield advantages in intercropping system

Journal of Maharashtra Agricultural Universities 13(1): 56-58

An intercropping of sorghum (CSH-6), red gram (UPAS-120), green gram (S-9) and soybean (Bragg) with two plant populations for each component crop (50 and 100% of their normal plant population) in a paired row system was studied during kharif 1979 and 1980. The highest land equivalent ratio (LER) was obtained by red gram + green gram (1.55) followed by sorghum + red gram (1.45) during 1979 and again during 1980, red gram + green gram showed the highest LER (1.54). Effective LER curves indicated that higher yield advantages were obtained in better rainfall year (1979) with greater proportion of base crops like sorghum and red gram and comparatively with their lesser proportion in relatively dry year.
