Abstract
Soybean plant development can be implemented through the utilization of palm oil plantations. Peat soils have many constraints such as low pH, and poor-nutrient. On peat soil nutrient deficiencies can be overcome by the provision of organic and inorganic fertilizers, such as TKKS compost. These organic materials affect plants indirectly through the changes in physical, chemical and biological soil. Study aims to determine the best fertilizer composition for growth and production of soybean palm oil plantations on peatland. The study was conducted in Rimbo Panjang, Tambang District, Kampar regency, in October 2011 to February 2012. Research used Completely Randomized Design (CRD), 5 treatments and 4 replications. Treatment A (without fertilizer), B (TKKS 0 tons/ha and Urea, TSP, KCl 100% recommended dose, 2 tons/ha ash bunch and 1 week of incubation), C (TKKS 5 tons/ha and urea, TSP, KCl 75% of the dose, 5 tons/ha ash bunch and 4 weeks of incubation), D (TKKS 10 tons/ha and Urea, TSP, KCl 50% of the dose, 4 ton/ha ash bunch and 3 weeks of incubation), E (TKKS 15 tons/ha and Urea, TSP, KCl 25% of the dose, 3 tons/ha ash bunch and 2 weeks of incubation). The results showed treatment E, (TKKS 15 tons/ha and Urea, TSP, KCl 25% of the dose, 3 tons/ha bunch of ash and 2 weeks of incubation, a composition of the best treatments for crop growth rate (0.37 g), the number of pithy pods per plant (71.15 units), production per plot (603.04 g) and production efficiency (1466.22%).
