PEMBERIAN BERBAGAI DOSIS KOMPOS TERHADAP PERTUMBUHAN DAN PRODUKSI TANAMAN KEDELAI PADA TANAH YANG TELAH DIINOKULASI DENGAN MIKORIZA

Abstract

The need for soybeans is increasing from year to year, while domestic soybean production is still very low. Therefore it is necessary to improve cultivation techniques in order to increase soybean production. One of the efforts that can be done is to improve fertility by providing compost and mycorrhizal bio-fertilizers. Mycorrhizae play a role in increasing plant growth by increasing the ability of the roots to absorb the nutrients needed and increasing plant resistance to other extreme conditions. The research was conducted in the greenhouse of the Faculty of Agriculture and Microbiology Laboratory of LITBANG Forestry Makassar. The experiment was designed in a randomized block design consisting of four treatments, namely: without compost (control), compost 2 tons / ha (8 g / plant), compost 4 tons / ha (16 g / plant) and compost 6 tons / ha (24 g / plant). The results showed that the application of compost as much as 8-16 g / plant on the mycorrhizal inoculated soil resulted in significantly higher soybean plant production. The application of compost 8-16 g / plant using soybean host plants obtained the percentage of mycorrhizal infections up to 100% and increased the availability of available-P nutrients.
