Effect of Different N Management Practices and Planting Geometries in Cotton-mungbean Intercropping System

Abstract: The study was undertaken to determine the performance of cotton and mungbean, when grown simultaneously in different geometric proportions and fertilized by various methods. Compared to sole cropping, the yield of interplanted cotton was reduced significantly by increasing the density of recessive component of intercropping system. The reduction in seed cotton yield was accounted to be 30% in 1:1 and 40% in 1:2 cotton-mungbean planting geometry. However, statistically similar seed cotton yield to that of sole cotton was recorded from the system following 2:1 row arrangements of cotton and mungbean. Fertilizer N applied by banding alongside the rows of cotton produced significantly higher seed cotton yield as compared to broadcast applications, whereas, N applied through broadcast method over entire plot led to higher mungbean harvest when compared with the treatment receiving fertilizer N by banding technique. Cotton and mungbean interplanted according to 2:1 row arrangements surfaced as the most compatible system by producing combined yield of 4465 kg ha -1, which was 18.7% higher than monoculture cotton.
