Abstract
A field experiment was conducted on early dry season of April to July 2014 to evaluate the effect of applying biocompost and biochar on the growth and yield of soybean and soil fertility status. The experiment was set up using a Randomized Block Design. Two factors tested were biocompost and biochar. Biocompost consistist of four rates : 0, 5. 10, and 15 ton ha-1 and biochar consist of five rates: 0, 10, 20, 30 and 40 ton ha-1. The results of the study showed that : plant height only increased significantly at plots treated with biocompostwhile no significant effect was recorded at all biochar treated plots. Biocompost increased yield of soybean up to 2.25 ton ha-1while biochar at 10 ton ha-1 increased the yield reached to 2.09 ton ha-1. Combination both of biocompost and biochar improved soybean nodulation by 67.22% resulted in increased of nitrogen uptake by plants. At control,no added organic amendements, the concentration of N in plant tissues was 4.4% which was much lower compared to plots treated with biocompost and biochar.Application of biocompost and biochar improved soil fertility (i.e. organic-C and CEC).
