Phosphorus and Boron Application on Growth, Yield, and Quality of Soybean Seeds (Glycine max [L.] Merril)

The increased of growth, yield and quality of soybean seeds are expected to occur by applyingP (phosphorus) and B (boron). This research was to investigate the effect of P and application of B their response on growth, yield and quality of soybean seeds. This research was conducted at fieldland and the Laboratory of Seeds and Plant Breeding, Faculty of Agriculture, University of Lampung from November 2016 to April 2017. This treatment was arranged in a 6 × 2 factorial consisting of six doses of P2O5 (0; 50; 100; 150; 200; 250 kg/ha) and two concentration of B (0 and 5 ppm). This study was designed in Randomized Complete Block Design (RCBD) with three blocks. Homogeneity of variance was tested by Barlett’s test and non-aditivity model using Tukey’s test and continued by orthogonal polynomials at α 0.05. The results showed that applying P to dose 250 kg/ha increase the growth, yield and quality of soybean seeds in all variables. Whereas the applications 5 ppm of Boron increased growth, yield and quality of soybean plant seeds higher than without Boron on avariable number of unfallleaf, dry weight of plant, 100 grain weight, germination, dry weight of normal seedling, and vigor index. Response of growth, yield and quality of soybean seeds to increased doses of P did not depend on the granting of B.
