Abstract

Crop productivity loss due to soil erosion by water plays an important role in degrading soil health and economic loss to the farmers. The multiple regression methodology used for determination of soil erosion-productivity relationship is quite reliable and may be utilized to find out erosion – productivity relationship. The results indicated that maize and wheat yield is declined due to soil erosion not only below the soil loss tolerance level but also below the lower limit (very slight) of potential erosion rates. For moderate to severe erosion class, the predicted potential erosion rate overestimated compared to observed productivity loss. The results of this study are useful in estimating the economic loss of crop productivity due to soil erosion and would be helpful in determining crop productivity loss due to soil erosion for other crops of this region.
