PENGARUH KOMPOS PUPUK KANDANG SAPI DAN MIKROBA PELARUT FOSFAT TERHADAP PERTUMBUHAN DAN PRODUKSI TOMAT (Lycopersicum esculentum Mill.) PADA TANAH ULTISOL

Abstract

This study aims to (1) compare the effect of application with and without phosphate solubilizing microbes in the growth and yield of tomato in Ultisol (2) to compare the effect of multiple doses of cow manure composts in the growth of tomatoes in Ultisol (3) to determine the dose of compost with or without microbial solubilizing for the best yield of tomato plants. The treatment was applied in 2 x 5 factorial design with three replications. The first factor was the solubilizing microbes, with doses of 0 g / l of water (P0) and 20 g / l of water (P1) and the second factor was the dose of organic materials, namely 0 tons / ha (B0), 10 tons / ha (B1), 20 tons / ha (B2), 30 tons / ha (B3), and 40 tons / ha (B4). Each unit of the experiment applied to the experimental plots according to the randomized group design. The results showed that (1) Leaf Area Index analyses showed a similar pattern, namely a quadratic pattern. (2) Application with and without phosphate solubilizing microbes did not give a real difference to the growth and production of tomatoes unless the tomatoes sugar level. (3) Application of compost 40 tons / ha and 30 tons / ha without MPF scheme (P0B4) gave the best result in the production of the observed variables. However,in the treatment of compost wich is accompanied MPF scheme (P1B0, P1B1, PIB2, P1B3, and P1B4) , it showed that the presence of MPF scheme in the compost doses of 10 ton and 20 tons (P1B1, and P1B2) provided products that were not significantly different with the application of compost 30 tons and 40 tons (P1B3 and P1B4).
