Abstract
Soybeans inter cropping with the potential of palm oil on peatland done, although there are constraints soil acidity and the availability of phosphorus and potassium. The study aims to determine the effect and find the best treatment of some fertilizers and ameliorant soil composition of the components of soybean production. The study was conducted with a completely randomized design, 5 treatments 4 times repetition. Treatment A (without fertilizer and ameliorant soil), B (compost TKKS 0 tons / ha and 50 kg Urea / ha, TSP 150 kg / ha, KCl 100 kg / ha, 2 tons / ha ash bunch and 1 week of incubation), C (TKKS compost 5 tons / ha and Urea, TSP, KCl 75% of the dose, 5 tons / ha ash bunch and 4 weeks of incubation), D (TKKS compost 10 tons / ha and Urea, TSP, KCl 50% of the dose, 4 ton / ha ash bunch and 3 weeks of incubation), E (TKKS compost 15 tons / ha and Urea, TSP, KCl 25% of the dose, 3 tons / ha ash bunch and 2 weeks of incubation). Parameters: plant height (cm), weight of root nodules and effective nodule weight (g), harvest (HST), the percentage of pithy pods, dry seed weight per plot (g), dry weight of 100 seeds (g). The results showed the provision of fertilizer and ameliorant soil composition enhances growth and production of soybean in inter cropping pattern with palm oil. The conclusion that E treatment (compost TKKS 15 tons / ha and Urea, TSP, KCl 25% of the dose, 3 tons / ha ash bunch and 2 weeks of incubation) is the best treatment because it can provide the highest production.
