摘要

Cotton (Gossypium sp.) yield found varied from upper toposequence to bottom toposequence and it also found got affected due to low soil moisture availability in upper toposequences and excess soil moisture conditions in lower to bottom toposequences. Result showed that degree and extent of soil degradation among the toposequences are evaluated as the main barrier in successful crop production. Our results suggest that cotton arboreum being short duration performed better on upper to middle toposequences, while cotton hirsutum on lower to bottom toposequences under similar level of management. Moisture conservation practices, such as ridges and furrows found beneficial in improving soil moisture and finally seed cotton as well as intercrops yield as compared to flat bed (Farmer practices) sowing. Further, result showed that cotton (arboreum) + sorghum on ridges and furrows in upper plain; cotton (liirsutum) on contour + supplemental irrigation (through harvested rainwater) on middle plain, and cotton + soybean on ridges and furrows in lower plain found beneficial in increasing not only the yield of cotton-based cropping system but also found effective in reducing excess runoff and soil loss, improving water percolation and developing better environmental conditions for proper root proliferation and improved water use efficiency per unit area. However, moisture conservation measures increased significantly number of bolls, boll weight and yield per plant of cotton in all the toposequences and finally gross yield (q ha~(-1)) and gross return (Rs. ha~(-1)). Among the toposequences, crop cultivation on lower to bottom toposequences was evaluated as economically suitable, environmentally sound and socially acceptable; while on the upper toposequences, cover crop such as greengram and soybean should be grown or be put under permanent pasture to reduce further soil degradation.
