Optimizing Consumption Management Nitrogenized Fertilizers to Increase Nitrogen Efficiency in Wheat

Nitrogen is one of the most important macro nutrients in agricultural crops. This experiment was conducted in a randomize complete block design with 7 treatments in 3 replications in 2 area (first with loam texture, and second with clay loam texture). Treatments were: control (without N), 150 Kg.ha -1 N– Urea in 3 split, N based on farmers method, 150 Kg.ha -1 N– Urea in 2 split, Total N from S.C.U, 1/3 N from S.C.U fertilizer 1/3 Urea 1/3 Urea, 1/3 Urea from complex fertilizer 1/3 Urea 1/3 Urea. In this research characteristics that studied were: yield of grain, field efficiency and N efficiency. Maximum of yield relate to the treatment 1/3 Urea from complex fertilizer 1/3 Urea 1/3 Urea with 5039 and 5112 kg.ha-1 of loam and clay loam locations respectively. Maximum of field efficiency belongs to treatment 1/3 Urea from complex fertilizer 1/3 Urea 1/3 Urea with 13.4 and 12.17 (kg.kg-1 N) of loam and clay loam locations respectively.
