Abstract :Appropriate nitrogen and optimum irrigation scheduling ensure economic yield. To access the behavior of development, growth and yield of wheat in response to nitrogen rates insert ignore into journalissuearticles values(80, 120 and 160 kg ha-1 ); and irrigation scheduling, an experiment was conducted at Agronomy Research Area, University of Agriculture, Faisalabad using Randomized Complete Block Design in split plot arrangement. It was observed that accumulated thermal time and photo-thermal time derive the crop phenology. Calendar time of growth stages may vary depending upon the prevailing climatic conditions particularly minimum and maximum temperatures. Application of 120 kg ha-1 nitrogen insert ignore into journalissuearticles values(F2); resulted in maximum LAI insert ignore into journalissuearticles values(4.21 & 4.73);, mean crop growth rate insert ignore into journalissuearticles values(9.38 & 9.14 g m-2 d -1 );, and grain yield insert ignore into journalissuearticles values(3100 & 3265 kg ha-1 );. Full irrigation performed better in terms of maximum LAI insert ignore into journalissuearticles values(4.97 & 5.46);, mean CGR insert ignore into journalissuearticles values(10.89 & 12.66 g m-2 d -1 ); and grain yield insert ignore into journalissuearticles values(3735 & 4603 kg ha-1 );. Application of 120 kg Nitrogen ha-1 and full irrigation were found to be the best management practices for better growth and to attain maximum grain yield.
