Intercropping is a farming practice involving two or more crop species, or genotypes, growing together and coexisting for a time. On the fringes of modern intensive agriculture, intercropping is important in many subsistence or low-input/resource-limited agricultural systems. Intercropping in order to improve land use efficiency, take advantage of intercropping facilitation and improve economic benefits. Also, linked with the higher yield, the associated higher amount of vegetables-legume by-product is preferred for animal feed or human consumption. The objective of this study is to find out the suitable groundnut – chilli intercropping system and increase productivity, economic and nutritional development of charland farmers of Bangladesh. In the experiment, intercropping system such as One row of chilli in between two normal rows of groundnut, two rows of chilli in between two normal rows of groundnut which was compared with sole groundnut and sole chilli production. Total yields of chilli /groundnut intercropping were higher than that of sole chilli and groundnut. chilli /groundnut intercropping is the efficient use of light because of complementary use of space between the chilli plants and the groundnut plants. Chilli /groundnut intercrop gross return and BCR per hectare were found higher than from sole crop system. The total yield of intercropped crops was greater than sole cropping shown by LER>1. The overall advantage of intercropping ranged from 71 to 81%. The highest land equivalent value of 81% was recorded from paired row chilli in between four normal rows of groundnut sowing arrangements indicated a yield advantage of 81% over sole crop. |
