Abstract

This research aimed to study effect of dolomite and compound fertilizer on N and P uptake, growth and production of soybean in riparian lowland. This research was conducted at the experimental garden of PT Pupuk Sriwidjaja Palembang by testing nine treatment levels repeated three times, using a Randomized Group Design (RAK). The treatment levels in this study were, N0 = control; N1 = NPK 15-15-15 100% dose; N2 = dolomite + NPK 15-15-15 100% dose; N3 = NPK 16-12-16 100% dose; N4 = dolomite + NPK 16-12-16 100% dose; N5 = NPK 15-15-15 100% dose + MgO, Zn, DAP 100% dose; N6 = dolomite + NPK 15-15-15 dosage 100% + MgO, Zn, DAP dosage 100%; N7 = NPK 16-12-16 dosage 100% + MgO, Zn, DAP dosage 100%; N8 = dolomite + NPK 16-12-16 dosage 100% + MgO, Zn, DAP dosage 100%. The results showed that dolomite and compound fertilizer gave a significant effect on the parameters of plant height 4 weeks after planting, number of leaves 2 weeks after planting, and weight of soybean. The combined treatment of dolomite at a dose of 2.7 kg plot-1 + NPK 15-15-15 fertilizer at a dose of 225 g ha-1 + MgO, Zn, DAP at a dose of 44.9 g ha-1 gave better results on the highest uptake of N (294,0 mg tanaman-1) and P (20,7 mg tanaman-1), then produced the highest plant height at 4 weeks after planting (26,43 cm) and the highest soybean weight of (1393.07 g plot-1) or (1.4 kg plot-1), compared to other treatments.
