Abstract

The aims of this study were to find out the effects of runoff control techniques and cropping patterns on the runoff rate of sloping upland farming. A series of factorial experiments were conducted on a Lithic Dystrudepts located at three different sloping uplands in Malang, East Java. The area belongs to the C type of Oldeman climatic zone. The three runoff control techniques were soil pit with vertical mulch (T1), soil pit with ridge and vertical mulch (T2), and soil pit with a ridge (T3). The two sequential cropping patterns were maize (Zea mays L.) - soybean (Glycine max (L.) Merr.) - maize (P1), and peanut (Arachis hypogaea) - maize - soybean (P2). The result indicates that runoff control techniques decrease rate of runoff by 88%, for soil pit with ridge technique, 86% for soil pit with ridge and vertical mulch technique, and 84% for soil pit with vertical mulch technique. The relationship ofrainfallJx) with run off(y) can be expressed by y = 0.05x; r = 0.92 in cropped plot andy = 0.30x; r = 0.90 in bare plot. Keywords: ridge, soil pit, vertical mulch
