Abstract


Application of vegetative conservation which is highly effective in erosion control is the Agroforestry systems, especially in seasonal crop patternthat are directly related to the productivity of annual crops. The different plantingpattern of seasonal crophasa direct impact on the amount of erosion which occurs perrain eventmeasured with a scale of small plots method. The seasonal crops provide economic benefits based on costs and benefits, which can be seen from the net benefit/cost, net present value (NPV), and the return on investment which depends on the value of the interest rate, and is indicated as the internal
rate of return (IRR). Results showed that the agroforestry systems economically on forest trees of white teak with planting patterns of seasonal crop: inter-cropping plants, such as turmeric-corn- red bean – local cayenne pepper. This planting pattern gives the benefits; B/C ratio(1.44; 1.29; 1.59), NPV (Rp. 31.695.473; Rp. 21.009.395; Rp. 39.788.284) and IRR (0.22; 0.17; 0.15)respectively
