The Effect of Seed Coating with Trichoderma sp. and Application of Bokashi Fertilizer to the Quality of Soybean (Glycine max. L) Seed

Abstract

The decrease of soybean productivity was caused by low quality of seed. To improve the quality of seed, soybean seed were coated with Trichoderma sp. and adding bokashi organic fertilizer. This research aimed at finding the best dose combination of Trichoderma sp. and bokashi fertilizer to improve the quality of soybeans. The research was conducted in the experiment field and Laboratory of Seed Technology at Padjadjaran University in April - August 2017. The experimental design in this research was Randomized Block Design (RBD). The treatments were the combination of four dose values of coating the seed by Trichoderma sp. (0g/100 seeds, 1g/100 seeds, 2g/100 seeds, and 3g/100 seeds) and three dose of bokashi (0g/polybag, 300g/polybag, and 600g/polybag) and each treatment was replicated three times. The experiment result showed that all treatments on soybean seeds did not affect the germination percentange, vigor index, and conductivity value, but affected the seed quantityof 600g/polybag of bokashi and without seed coating with Trichoderma sp. on 100 seed mass and seed weight per plant.

Improving germination and quality of soybean seeds by using natural compounds

“…As a result, the rise in shoot fresh weight following IBA treatment may be attributable to increases in shoot length, leaf area, and leaf fresh weight. These results are consistent with previous studies which observed that the application of IBA promoted plant and shoot length, plant height, and dry weight of both branches and leaves (Umadi et al, 2018). The findings of the current study demonstrated that IBA treatment increased the length, weight, and number of shoots on soybean plants.…”

Study of Production and Distribution of Soybean Seeds In Central Java

“…According to [23], seed yield does not depend on the number of prospective seeds processed into clean seeds but is determined by the quality of the processed seeds. Umadi et al [24] state that observation on the weight of 100 seeds, the treatment combination generally had more significant results than the weight of 100 grain in the description of Anjasmoro varieties of soybean plants (14.8-15.3g/100 seeds). The importance of 100 seeds sources in their experiment range from 14.53 to 17.23 g/100 roots, which meant that the size of the seed was large (>14 g/100 seeds).…”
