英文摘要	Estimates of the soil and nutrient losses are essential for design and planning of soil conservation measures in Indian arid region. This study aims at estimating rainfall-runoff, soil and nutrient losses from different cover crops, and to identify the best cover for checking soil loss. The study is conducted for 2013-2015 in research farm of the Central Arid Zone Research Institute, Regional Station, Bhuj, Gujarat, India. Ten treatments comprising four sole-crop, that is, sorghum (Sorghum bicolor), pearl millet (Pennisetum glaucum), green gram (Vigna radiata), and cluster bean (Cyamopsis tetragonoloba) and four cereal-legume intercropping with two controls (cultivated and unplowed fallows) are undertaken in randomized block design with three replications. Multi-slot divisors are fabricated and installed. Analysis of variance (ANOVA) is performed, and their interrelationships are explored. The highest soil loss is recorded from cultivated fallow (108.03 +/- 49.95 kg.ha(-1).yr(-1)) and unplowed fallow (78.95 +/- 28.42 kg.ha(-1). yr(-1)). Green gram is found effective in controlling soil loss as sole-crop (event-wise soil loss similar to 0.54-33.94 kg.ha(-1)) as well as intercropping with sorghum (event-wise soil loss similar to 0.60-23.37 kg.ha(-1)) and pearl millet (eventwise soil loss similar to 2.45-31.11 kg.ha(-1)). ANOVA revealed significance (p < .05) of runoff-generating rainfall, crop cover, and their sole- and intercropping practices. Values of coefficient of determination (R-2) indicated highly corre- lated (R-2 >= 0.75) relationships of rainfall-runoff for all treatments, rainfall-soil loss for sole cereals and cultivated fallow, and runoff-soil loss for pearl millet and intercropping with green gram. This study concludes that cereal-legume intercropping diminishes the adverse impact of raindrops on soil erosion and crop production.
