 ABSTRACT

An experiment was conducted during rabi 2014-2015 on clay loam soil at irrigated upland farms of Eastern block, Tamil Nadu Agricultural University, Coimbatore to study the effect of integrated nitrogen management of sweet corn hybrid on certain soil biological properties. The experiment was replicated thrice, with 12 treatments comprising integration of organic manures viz., FYM, vermicompost, poultry manure, goat manure and biogas slurry at 2 levels (25 and 50 percent) with inorganic N at 75 and 50 per cent. The remaining two treatments were 100 per cent N as inorganic fertilizer and 100 per cent N as inorganic fertilizers with 12.5 t ha-1 of FYM. The microbial population and Urease, Dehydrogenase and Phosphatase activity in the soil at different growth stages of sweet corn hybrid by adopting standard procedure. The soil micro flora and enzymatic activity were found greater due to application of 50 per cent N as biogas slurry with 50 per cent N as inorganic. However, it was comparable with 50 per cent N as vermicompost + 50 per cent N as inorganic and 50 per cent N as FYM + 50 per cent N as inorganic. The 100 per cent N applied plot as inorganic registered lesser microbial load and soil enzymatic activity.

Keywords: Soil microbial population, Urease, Dehydrogenase and Phosphatase activity.
