Abstract (English) :
Critical land has continously increased, on the other hand, farmers use the critical land for intensive cultivation. Based on this condition, land rehabilitation should be done in order to improve soil properties as well as to increase crop production. To support the condition, a study was conducted in order to get information effect of limimg and manuring on soil properties and crop production. The applied treatments were additional 6 ton lime/ha, manure 6 ton/ha to the local farming system. The plot control was the local farming system. Erosion control was done by planting gliricidae and annual plant including jenetri, Parcia speciosa and Teak. The study results showed that application of lime 6 ton/ha and mannure 6 tonlha increased chili production 25 % and 20 % and 40 % and 36 % of cassava. The annual plant growth during 10 months for diameter and height of jenetri ( 1. 4 Cm and 157,1 Cm), (1.2 Cm and 76.3 Cm) and teak (1.8 Cm and 139.8 Cm). Comparing to soil properties in the plot control, lime and manure application had improved little bit soil properties, especially in soil pH, soil organic matter, total nitrogen, cation exchange capacity and bulk density. Meanwhile, phosphor and potassium availability decreased. Financial analysis showed that with an average chili price Rp.2.500,-lkg, application of 6 ton lime/ha caused profit Rp.2.661.250,-IHa and application of manure 6 ton/ha the profit was Rp.2.698.750,-IHa. The study showed that local farmers have not applied the introduced technologies as a whole, only some of them have planted annual plant.
