Abstract

The growth and yield of EM treatment of seed, seedling nursery bed, field and all above combinations in paddy rice and maize were investigated. EM cultures were applied 2 to 6 times at dose of 20 l per ha. The yield of rice and maize increased by 7.2 to 7.4% in seed treatment, 7.1 to 7.4% in seedling nursery bed treatment, 4.2 to 13% in field treatment, 9.5 to 14.9% in combination treatment, and 9.0 to 30% on continuous application of EM than each control. Application of EM increases the number of beneficial microorganisms, available nutrients and content of organic matter in soil, and it enhanced the neutralization of soil.
