Abstract :This research investigates an artificial neural network for predicting the chlorophyll concentration index and the effect of different nitrogen doses on the yield, yield components of Bread Wheat insert ignore into journalissuearticles values(Triticum aestivum L.);. Plants were fertilized with 5, 10, 15, 20, and 25 kg da-1 nitrogen doses. The chlorophyll concentration index of each leaf was measured using a SPAD meter. The coefficient of determination values was found to be 0.99. In artificial neural network modeling, chlorophyll concentration values were estimated with SPAD readings. Artificial neural network modeling successfully described the relationship between actual chlorophyll concentration index values and predicted chlorophyll concentration index values. Agronomic parameters plant height insert ignore into journalissuearticles values(110.66-92.73 cm);, the number of spikes per square meter insert ignore into journalissuearticles values(461.01-355.50);, the number of seeds per spike insert ignore into journalissuearticles values(43.88-23.83);, the weight of seed per spike insert ignore into journalissuearticles values(2.07-0.91 g);, hectoliter weight, thousand-grain weight insert ignore into journalissuearticles values(43.10-35.89 g);, grain yield insert ignore into journalissuearticles values(638.76-343.06 kg.da-1);, protein contents insert ignore into journalissuearticles values(11.16-8.34 %);, the value of sedimentation insert ignore into journalissuearticles values(19.40-11.94); were found statistically important.
