Abstract:
This experiment aims to determine the best dose of rock phosphate for growth and yield of mungbean (Vigna radiata L.) varieties No. 129 in medium peat. The experiment was conducted in the Kutilang Sakti street, Panam, Pekanbaru which started from August to October 2011. This study is conducted experimentally using Completely Randomized Design (CRD), which consists of 5 treatments and 3 replications. The treatment given is without rock phosphate fertilizer , 50% of rock phosphate fertilizer dosage recommendation, 100% of the rock phosphate fertilizer dosage recommendation, 150% of the dose of phosphate rock and fertilizer recommendations 200% of the dose of rock phosphate fertilizer recommendations. The data obtained were statistically analyzed by analysis of variance (ANOVA). When F count showed significant effect, then performed further tests Least Significant Difference (LSD) at the 5% level. The results obtained are rock phosphate fertilizer in peat soils affect the growth and yield of green beans. Rock phosphate fertilizer in peat medium gives a real difference on plant height, plant canopy dry weight, root dry weight of plants, the percentage of pithy pods and seed weight per plant. Best rock phosphate dosing in this study was 100% of the dosing recommendation is 0.372 g/polybag with a production of 3.88 g/plant.
