Samanhudi, B. Pujiasmanto, A. Yunus, Supyani, Suntoro, H. Widijanto and S. M. Prabowo, 2017. The effect of manure and mycorrhiza application to the soil microbes biodiversity in terms of increasing soybean yield in marginal land in Indonesia. Bulg. J. Agric. Sci., 23 (6): 994–1003

The extensive of marginal land in Indonesia continues to increase for every year. These is can be solved using an alternative technology such as the utilization of microorganisms and organic matter. This research aimed to study the effect of various types of manure (cow, goat, quail) and mycorrhiza in soil microbial biodiversity in terms of soybean yield in marginal lands. The research used Randomized Complete Block Design (RCBD) which consists of two factors, the mycorrhiza treatment with two levels and types of manure treatment with five levels. So we got 10 treatment combinations, each of which was repeated three times. The results showed that there was significant differences between without and with mycorrhiza treatment as biodiversity of microbial populations were higher in the treatment with mycorrhiza than without mycorrhiza. There were 22 types of bacteria in all samples, while fungi were identified in four genera which are Aspergillus sp, Penicillium sp, Rhizopus sp, and Mucor sp. Treatments with mycorrhiza provide higher yields than without mycorrhiza but the result did not show significant result.

Key words: marginal land; mycorrhiza; soil microbial biodiversity; soybean
