Effects of Effective Microorganism on Corn Growth and Yield

Abstract

Pot experiment was carried out to examine the effects of Effective Microorganism (EM) on growth, dry weight and yield of corn at Nakhonsawan Field Crops Research Center in 1994 rainy season. The treatments were a) treated with or without EM on steriled or non steriles soil. b) treated with or without EM on steriled or non steriled sand. The results showed that most treatments with EM gave slightly higher plant than treatments without EM except on non steriled soil which gave reverse result. For plant dry weight, the result were almost the same as for plant height except on steriled sand which showed reverse result, but no statistical difference were found on all soil treatments, very low grain yield were recorded and the difference on yield between treatments with or without EM could not be detected, But, on all sand treatments, no any grain yield could be hasvested.
