Abstract
Increasing potato productivity on suboptimal land is needed since potato is widely consumed by people in various food types. Research was conducted at the BB Biogen Segunung, Pacet District, Cianjur Regency, West Java Province that is characterized by soil with acidic reactions, medium organic matter content and low total organic-N and exchangeable-Mg, very high available-P, high exchangeable-Ca and K. Increased productivity is designed through providing various levels of lime, Biobos, and manure fertilizer along with basic fertilizers (ZA, SP 36, and KCl). Overall, there were ten treatments, namely, 1) P1 (lime level1, manure fertilizer level1, basic fertilizer)- 2) P2 (lime level1, Biobos level1, basic fertilizer)- 3) P3 (lime level2, manure fertilizer level1, basic fertilizer)- 4) P4 (lime level2, Biobos level1, basic fertilizer), 5) P5 (lime level1, manure fertilizer level2, basic fertilizer)- 6) P 6 (lime level 1, Biobos level2, basic fertilizer)- 7) P7 (lime level2, manure fertilizer level2, basic fertilizer)- P8 (lime level2, Biobos level2, basic fertilizers)- and 9) P9 (basic fertilizers), 10) P10 (control, without lime, Biobos, manure fertilizer and organic fertilizer). P5 treatment resulted in the best growth and production of potato. The combination of the largest manure fertilizers and low level lime provided the highest productivity increased.
