Abstract:
The preliminary research study was carried out in D block, Department of Agronomy, Tamil Nadu Agricultural University, Agricultural College and Research Institute, Madurai, to evaluate the role of surface area of crop residues through chopping and its impact on soil biological and chemical properties through decomposition. Four different crop residue such as paddy straw, maize stalk, cotton stalk and blackgram stalk along with absolute control was taken for the study. The experiment was laid out in randomized block design with three replications. The data computed during 0th, 15th and 30th days were statistically scrutinised and expressed here as percentage increase in 30 days interval. The study revealed that blackgram stalk incorporation with chopping recorded higher percentage values on microbial load in soil, soil available N, P, K and organic carbon (OC) and also the dehydrogenase enzymatic activity followed by without chopping treatment. This was also followed by cotton stalk, paddy straw and maize stalk with chopping. The least activity was found with paddy straw and maize stalk treatment without chopping and no residue incorporation.
