Study of Humic Acid and Multiantagonis of Streptomyces Sp, Trichoderma Sp Application Techniques for Horticulture Plant on Marginal Soil

摘要

Tomato, red pepper and melon are high-value horticultural crops. Crop production will be decrese couse of pathogenic microorganism and Pest. Some soil saprophytic microorganisms are natural enemies of soil-borne pathogenic microorganisms and pests. Streptomyces sp., Trichoderma sp. is a biological agent, decomposer, and a growth hormone producer. The purpose of the experiment to study humic acid and multiantagonis of Streptomyces sp, Trichoderma sp application techniques for horticulture plant on marginal soil. The study was carried out in Pare (regusol soil) and Gresik (vertisol soil), prepared in Completely Randomized Design with different treatment factors for application technic of multiantagonis doses of 100 ml, 200 ml and 300 ml every plant treatment. Horticulture plants were tomato, chili and melon. The results showed that the Application of humic acid and multiantagonic could more increase the production of chilli tomatoes and melons than the production of controls. The average production of tomatoes, melons and peppers in Pare (regusol) is higher than the average production in Gresik (vertisol).
