The Government of India introduced neem coated urea prills as an alternative to traditional urea prills with a view to improve the nitrogen usage efficiency by inhibiting nitrification. Neem was chosen because it contains Azadarachtin, which acts as a nitrification inhibitor in addition to its insecticidal properties. A laboratory experiment was set up for a study period of 18 days to compare the efficiency of neem coated urea as an effective nitrification inhibitor in comparison with normal urea. Results revealed that the neem coated urea was able to retard nitrate formation by 60 % at its maximum concentration and 52.5% on an average when compared with normal urea.
