Abstract

To determine the effect of farm slopes on yield and some agronomic traits of wheat under different fertilizer treatments, an experiment was performed as split plot based on randomized complete block design with three replications in Piranshahr in 2011-2012. Treatments consisted of farm slope at four levels: (zero, 3, 6 and 10 %) as the main plots and combination of different fertilizer at five levels: (control, application of biofertiliozer (Nitroxin), manure, chemicals (N and P) and integration of biological, manure and chemical as sub plots. Results showed that the highest (7.67 t/ha) and lowest (3.68 t/ha) seed yield obtained from farm slope 0 and 10%, respectively. In fact, with increasing of the farm slope, the yield components decreased which lead to 52% and 38% reduction in grain yield and total biomass of plants located on a slope of 10 percent than the control plants. Also, the applications of integrated fertilizer treatments had the most effect on morphological traits and yield components of wheat that increased 12.58 and 13.58 percent the seed yield and total biomass compared to the control plants.
