Abstract :Nitrogen insert ignore into journalissuearticles values(N); is necessary sustenance for healthy plant growth and its yield. Urea is a primary source of N in solid fertilizers. The hydrolysis rate of urea accelerates as it stays in surface application. However, Controlled-Release Fertilizers insert ignore into journalissuearticles values(CRF); has proven to reduce N losses, thereby increasing fertilizer efficiency. Wheat is the leading food grain of Pakistan occupying the largest area under single crop. It accounts for 9.6 percent of the value added in agriculture and 1.9 percent GDP. However, the production is recorded less as compared to previous years due to imbalance fertilizer application practices. The recommended doses of fertilizers may vary time to time for wheat. This study is therefore, planned to evaluate the method and appropriate rate of N for wheat, based on these specific objectives: 1); to evaluate an appropriate method and dose of N application for wheat and 2); to find out the effect of different N applications on growth and yield of wheat. In this regard, a field experiment was conducted at Wheat Section, Agriculture Research Institute Tandojam. There were 5 treatments examined on one variety insert ignore into journalissuearticles values(TD1); of wheat with three replications. The encapsulated urea was prepared manually in the laboratory of Department of Soil Science, Sindh Agriculture University Tandojam. Results revealed that wheat yield was markedly influenced by encapsulated urea as compared to surface applied urea. Maximum yield insert ignore into journalissuearticles values(40.5 % increment over control); was observed from encapsulated urea insert ignore into journalissuearticles values(N 140 kg ha -1 );. However, the difference between the rates of N was non-significant insert ignore into journalissuearticles values(p > 0.05);.
