Agricultural Wastes based-Organic Fertilizers (Bokashi) Improve the Growth and Yield of Soybean (Glycine max (L.) Merrill)

Abstract: , International Journal of Agricultural Science, 2016

This research was conducted at the field research station and in the Laboratory of Agrotechnology, Faculty of Agriculture, University of Halu Oleo, Kendari, Indonesia in 2016. This study aimed to determine the effect of using a variety of Bokashi (compost) fertilizers made from agricultural wastes on the growth and yield of soybean. The study was arranged in a randomized block design (RBD, which consisted of 5 treatments, namely: without Bokashi fertilizer (M0), Bokashi “komba-komba” (Chromolaena odorata)(M1), Bokashi “water hyacinth” (Eichornia crassipes)(M2), Bokashi sago dregs (M3), and Bokashi burned-rice husk (M4). Research data were analyzed using ANOVA and treatment means were compared using Honestly Significant Difference (HSD). The results showed that the application of Bokashi gave a significant effect on almost all variables observed on growth and yield of soybean. Bokashi burned-rice husk (M4) and sago dregs (M3) give the best effect on the growth and yield of soybean, which reached about 3.1 tonnes per hectare, an increase of approximately 30% compared to the treatment of without Bokashi which only reached 2.4 tons per hectare.
