Feasibility of soybean cultivation technology in rainfed area with acidic soil in Lampung

Abstract

In 2017, Indonesian Legumes and Tuber Crops Research Institute (Iletri) introduced a package of soybean cultivation technology in rainfed area with non-acidic soil in Maros, South Sulawesi named Biodetas which was able to produce the yield of 2.1-3.2 t/ha. In 2018, Biodetas was developed to East Lampung, Lampung which has specific rainfed area with acidic soil. Therefore, the technology has been modified by the addition of dolomite and named as “specific Biodetas”. To finding out the results of “specific Biodetas” application in improving soybean productivity and farmers’ income, there are three treatments involved: P1 = Doing tillage and planting with manual dibbling tool, P2 = Doing tillage and planting with simple planting tool, and P3 = No tillage and planting with simple planting tool. P2 and P3 were specific Biodetas adjusting to the existing farmers’ cultivation. The yield of specific Biodetas were 1.362-1.727 t/ha. P3 produced the highest yield and the highest total benefit of IDR 6,670,500/ha. The specific Biodetas adjusting to the existing farmers’ cultivation could provide additional benefit of IDR 640,000 for P2 and IDR 3,706,000 for P3. MBCR values of P2 and P3 were 3.64 and 4.92, respectively, reflected that the technologies were feasible to be applied.
