Field experiment for studying the specific response of Deana Durum wheat variety to the stand density 350, 450 and 550 germinable seeds/m2 and to the rate of nitrogenous fertilizer N60, N120 и N180 kg/ha applied has been carried out during the 2006-2009 period in the Experimental Field of the Plant Growing Department of the Agricultural University in Plovdiv with the purpose of establishing optimum values for these factors in the process of studied variety growing. The following inferences have been drawn from this study. The Deana Durum wheat variety on the average for the period, manifested most fully its productive capacities when grown with 350 germinable seeds/m2 and applying 120 kg/ha nitrogenous fertilizer in active substance. It was established that Deana variety produced the highest average grain yield of 356 kg/ha 15,2% due to the higher number of the grains and weight of the grains per spike.
