Optimal spatial arrangement and population levels in corn (Zea mays L.) and mungbean (Vigna radiata (L.) Wilczek) strip intercropping

Joshi, M.
The best LER [land equivalent ratio] value over seasons (1.39) suggests that 2:4 spatial arrangement permitted the exploitation of high population density of corn (33,000 plants/ha of total intercropped area or equivalent to 66,000 plants/ha in full stand) intercropped with a low population density of mungbean (132,000 plants/ha of total intercropped area or 200,000 plants/ha in full stand). The yield of corn per ha increased with increasing plant population and were more favored by the 2:4 spatial arrangement. An adverse shading effect due to corn was observed in all the intercropped mungbean. Yield reduction per ha and per plant of the intercropped mungbean was 57% and 29%, respectively. Leaf area index (LAI) and total dry matter increased with increasing population levels in both crops, with the greater increase in the intercropped corn. Harvest index in both crops was much influenced by seasons
