The main objective of the experiment was to determine the effect of slope gradient on the plant cover index C of small bean crops. The impact of two slope gradients (9 and 16 percent level of surface soil losses was studied, as was, in the experiment, the amount of surface soils exported from fallowed plots and from the plots grown with faba beans. The experiment on the impacted 22.13 x 1.87 m plots was four times repeated in each gradient zone. It was stated that the plant cover index C was 0.187 in the case of faba beans grown and cropped on the slopes showing a 16 percent gradient, and, it was 0.154 on the slopes with a 9 percent gradient. The impact of the total area of plant top ends expressed by an index called LAI (Leaf Area Index) on the value of index C is described by exponential functions
