摘要

A field experiment was conducted during 2003-04 to 2005-06 at the Central Soil Salinity Research Institute, Regional Research Station, Lucknow to find alternate options to the rice-wheat cropping system in partially reclaimed sodic soils. Four cropping systems, viz. rice-wheat (cereal-based), sorghum-berseem (fodder-based), sweet basil (tulsi)-matricaria (medicinal and aromatic crop-based) and chilli-garlic (spices-based) were evaluated in the light of sustainability, potentiality and profitability. Maximum rice equivalent yield (14.21 t ha(-1)) was recorded with sweet basil-matricaria cropping system, whereas the highest production efficiency (61.25 kg ha(-1) day(-1)) was recorded with sweet basil-matricaria cropping system. Sorghum-berseem cropping system gave maximum (78.35%) land-use efficiency. Chilli-garlic cropping system recorded the highest water expense efficiency (150.72 kg ha(-1) cm) followed by sweet basil-matricaria, but the total amount of water used was more (125.65 cm) in the rice-wheat system. The water requirement of sorghum-berseem, sweet basil-matricaria and chilli-garlic cropping systems was 8.0, 19.8 and 31.8% respectively, less than the rice-wheat cropping system. Among the cropping systems evaluated, energy input (27.50MJ ha(-1)) and output (314.46 MJ ha(-1)) were maximum in the rice-wheat system. Energy use efficiency was maximum (11.99) with sweet basil-matricaria followed by sorghum-berseem (11.91). Reclaiming effect of sweet basil-matricaria cropping system on soilproperties was higher than the rest of the cropping systems. Sweet basil-matricaria cropping system gave the highest net return (Rs 50,222 ha(-1) and benefit: cost ratio (2.74).
