Uptake Pattern in Relation to Form and Time of Application of Nitrogen for Rice

Abstract

A study was made to find out the uptake pattern of rice IR.20 under moderate level of nitrogen in relation to the time of application as well as form of fertilizers. The result shows that the nitrogen content increased after each split application and there was a general drop in the nitrogen content at around 67 days after transplanting due to transition phase from vegetative to reproductive phase. The nitrogen uptake followed the trend of dry matter production and nitrogen content.
