CROP GEOMETRY-INTERCROPPING WITH WIDER INTER-ROW SPACING The technology of successful raising of inter-crops like wheat, potatoes, Brassica crops, Toria, Raya, Gobhi Sarson (vernacular names of Indian vegetable crops) in autumn cane and Sunflower, Spring maize, summer pulses like green gram and black gram in spring cane has been developed, greatly improving the economics of sugarcane crop grown alone in comparison to the major rice-wheat cropping system in Northern India. This technology consists of planting sugarcane at wider inter-row spacing of 135-150 cm without reduction in cane yield as compared to closer inter-row spacing of 75-90 cm.
SUNFLOWER INTERCROP WITH WIDER INTER-ROW SPACING However, the seed rate per unit area has to be 50000 three budded seed setts per hectare both in close and wider inter-row spacing. This technology minimizes competition between the companion crops viz. the sugarcane and inter-crops. The cane quality of wider row spaced crop is better and less prone to insects like stalk borer. Moreover the yield of ratoon crop of wider row spaced crop is higher than the plant crop.
SUNFLOWER INTER-CROP
SPRING MAIZE INTER-CROP IN PAIRED ROW PLANTING This technology can help in multi-cropping and diversification of agriculture greatly in Northern India and improve the economics of sugarcane crop. The production of sunflower which otherwise affects the cane crop adversely when sown as inter-crop in closer cane inter-row spacing of 75-90 cm would increase considerably with wider inter-row spacing as there is no adverse effect of sunflower on cane. Similarly the potential of spring maize production would also increase vastly with this technology. This crop geometry of wider inter-row spacing of 135-150 cm and paired row planting can be adopted on a large scale to improve cane yield, sugar recovery and also obtain additional intercrops, which will help in popularizing multiple cropping and diversification of agriculture to fetch more income to the farmers. |
