Abstract
Abstract Soil erosion, a serious problem in Submontane Punjab, India, has been intensively studied by a number of investigators. Various soil management practices, such as the use of diverse crops, strip cropping, increasing crop cover, multiple cropping, agroforestry, mulching, conservation tillage, ridging, and furrowing have decreased erosion. Maize at a spacing of 60 cm x 22.5 cm showed minimum soil loss by runoff. Crops with erect growth and limited tilling allowed for high runoff and soil loss. The intercropping of groundnut with maize gave the highest net return with the least amount of soil loss by erosion; maize with urd (Vigna mungo L.) gave the second highest net return with the least amount of soil loss by erosion. Maize and guar (Cyamopsis tetragonoloba L.) in alternating strips of 9‐m width showed minimal runoff (9%) and soil loss (3.3 Mg ha‐1). The agroforestry practice of growing Leucaena leucocephala Lam. intercropped with maize, guar, or urd also was effective in reducing runoff and soil...
