Abstract
Suboptimal land area in Indonesia is increasing along with inadequate land management, including in agricultural centres. Improvement soil management in accordance with the cultivated commodity and the soil conditions is urgently required. Suboptimal soil in the research location at Cikeusal District, Serang Regency, Banten Province is characterized by acidic soil reactions, very low organic matter and low N, P, and Ca, Mg, K bases. Increased productivity is carried out through various levels of lime and organic matter along with basic fertilizers (urea, compound fertilizer N-P-K and dolomite). Overall, there were nine treatments, namely, 1) P1 (Petroganic level 1, lime level 1, basic fertilizer)- 2) P2 (Petroganik level 1, lime level 2, basic fertilizer)- 3) P3 (Petroganik level 2, lime level 1, basic fertilizer)- 4) P4 (Petroganik level 2, lime level 2, basic fertilizer), 5) P5 (lime level 1, basic fertilizer)- 6) P 6 (lime level 2, basic fertilizer)- 7) P7 (basic fertilizer)- P8 (urea and N-P-K fertilizers)- and 9) P9 (control, without basic fertilizers, lime and petroganik). P4 treatment resulted in the best growth and production of peanuts. The combination of the largest petroganic and lime levels to acid and very low organic matter soil provided the highest productivity increased.
