Abstract

Sole and intercrop rice had almost similar leaf, stem, and total dry matter, indicating that planting pattern did not affect the biomass production of the crop. The sole soybean and the sole pigeonpea produced higher dry matter than that of their respective intercrops because of a higher LAI and consequently higher light interception. Yield of the rice was relatively poor. The sole rice gave slightly higher yield than the intercrop. The sole soybean and sole pigeonpea also gave higher yields than their respective intercrops. Intercropped pigeonpea in the (3:1) ratio gave highest partial LER (0.98). The intercrop of rice with pigeonpea in the (5:1) ratio gave highest total LER (1.53) indicating a yield advantage of (53%) over the sole crop. When comparing root length of the crops, the intercropped rice with soybean gave highest partial LER (0.98). The intercrop of rice and soybean gave a total LER of (1.88), indicating 88% of root growth advantage over the sole crop.
