Abstract:
Nitrogen is an important macronutrient for plant function and key component of amino acids, which form the building blocks of plant proteins and enzymes. The field experiment to determine “Effect of neem coated urea under different nitrogen application schedule on physio chemical properties of soil in transplanted rice” was conducted at the Crop Research Centre of Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut (U.P.) the Kharif season of 2016. The experiment was carried out with eleven treatments and three replication comprising T1-control (No N), T2-50:25:25 N, T3-33:33:33 N, T4-25:25:50 N, T5-25:50:25 N, T6-00:50:50 N, T7-00:75:25 N, T8-00:25:75 N, T9-50:50:00 N, T10- 50:00:50 N through neem coated urea as basal, at maximum tillering and panicle initiation stage and T11- LCC based (≤ 4 critical value) and estimated in a randomized block design. The result revealed that the application of nitrogen through neem coated urea under different nitrogen application schedule did not show significant effect on soil physical (bulk density, moisture content, water holding capacity and infiltration rate) properties. The application of nitrogen through neem coated urea 25% at basal, 50% at tillering stage and 25% at panicle initial stage, respectively improve soil nutrient status like available nitrogen, phosphorus and potassium in soil.
