PERTUMBUHAN DAN PRODUKSI KEDELAI AKIBAT INOKULASI Rhizobium sp. DAN BAKTERI PELARUT FOSFAT TAHAN SALIN SERTA BATUAN FOSFAT DI TANAH SALIN

Abstract

<p>The purpose of this study was to examine the effect of <em>Rhizobium sp.</em> and phosphate solubilizing bacteria saline-resistant and the application of phosphate rock to the growth and production of soybean plants in saline soils. The study was carried out using a 3 x 4 factorial design on the basis of a Completely Randomized Design with 3 replications. The first factor is the treatment of <em>Rhizobium sp.</em> and phosphate solubilizing bacteria saline-resistant (CFU 109 cells/g) at 4 levels, namely F0 : 0 mg/pot, F1 : 10 mg/pot, F2 : 20 mg/pot, and F3 : 30 mg/pot. The second factor is the doses of phosphate rock with 3 levels, namely B0: 0 kg/ha, B1: 50 kg/ha, and B2: 100 kg/ha. The results showed that the inoculation treatment of <em>Rhizobium sp.</em> and phosphate solubilizing bacteria saline-resistant were not significantly different on the N uptake parameters of seeds. Treatment with different doses of rock phosphate had no significant effect on all parameters. There was no interaction between <em>Rhizobium sp.</em> and phosphate solubilizing bacteria saline-resistant with a dose of rock phosphate on all observed parameters. Inoculation of <em>Rhizobium sp.</em> and phosphate solubilizing bacteria saline-resistant and rock phosphate have not been able to significantly increase the growth and production of soybean varieties Anjasmoro in highly saline growing media with EC 6,26 dS/m, although there is a tendency to increase soybean production.</p>
