The cotton plant is a perennial with an indeterminate growth habit, and reputed to have the most complex growth habit of all major row crops. Cotton, which is grown for using fiber and oil is one of the most important and strategic crops through the world especially in Tamilnadu (India). Exogenous applications of biological and chemical substances have a many potential to promote the plant growth in different way, and the application of different chemicals may reduce stress induced inhibition of plant growth. In these experiments foliar spray of Neem oil was increased the Chlorophyll content (93.24%), humic acid (86.30%), and Trichodermaviride(73.50%) compared with others. In plants the Phyllosphere and Rhizosphere both the region was very important. The microbial load in above region was calculated in every treatment in that abundant microbial load was observed in 2A, 3A, 4A, 5A cotton seedling of Phyllosphere area after II treatment. In Rhizosphere region the III and IVth treatments were showed abundant microbial load. And also increased the plant shoot, root length, and Leaf lets number, Leaf size. The activity of these substances on cotton seedlings in every treatment was evaluated by using qualitative and quantitative methods. Spraying the aqueous solution of biological suspension on cotton plants has resulted in enhanced the growth and yield of cotton crops, and chemical spraying decreased the soil fertility. So, this study was carried out to find out the impact of foliar application of biological and chemical substances on cotton seedling was monitored and compared.
