The present research was carried out at the Experimental Center of Pampa del Arco of the Faculty of Agrarian Sciences of the National University of San Cristóbal de Huamanga during the months of January to May of 2016. The experiment was installed within an experimental design of divided plot, where the plots were located in the methods of mechanized tillage: a) disc plow and heavy dredge, b) heavy dredge and another heavy dredge pass and c) only heavy dredge for the seed cover. In the subplots nitrogen fertilization: a) 0 N, b) 40 N, c) 80 N and d) 120 N. The combination of factor levels was installed in three blocks. Where it was evaluated the agronomic parameters important for the yield of the wheat crop, among them: The length of stems, number of spikes per m2, precocity of the crop, weight of 1000 seeds, number of grain per ear and the weight hectolitrito; with a high statistical significance in the soil tillage factors and the nitrogen fertilization dose for the agronomic parameters under study. The influence of mechanized tillage methods and different levels of nitrogen fertilization on the yield and yield of the wheat crop under rainfed conditions were evaluated. The good soil tillage and a high level of nitrogen fertilization offer good development conditions to the plant and a better quality of the grain; in the preparation of the disc-plowed soil and with a heavy trawling course in the seed cover and dosing 120 kg.ha-1 of Nitrogen, had the highest wheat yield with 3860.3 kg.ha-1 and an economical yield of 187%; while in the zero-tillage treatment (without primary tillage) and without applying nitrogen fertilization the yield of wheat was 1257.8 kg.ha-1 and a yield of 23%.
