Influence of the period of sowing and the period of fertilizing on the elements of yield of durum wheat in the region of Pazardzhik
Ana Samodova
Abstract: Under the conditions of the years 2011-2013 on the cinnamon-brown forest soil (field of Experimental Facility of Irrigation Agriculture – Pazardzhik) three sorts of durum wheat were tested in two sowing periods (optimum and late one) and two periods of introduction of the nitrogen fertilizer (one time and two times). The purpose is to establish the influence of the sowing period and the nitrogen fertilizer introduction period on the yield elements (number of grain bearing stems, length of the grain part, number of grains per stem and mass of the grain per stem) with durum wheat varieties (Progress, Predel and Victoria). The influence of meteorological conditions on the sown crop density throughout the years of testing is wellknown. With the optimum period of sowing the plants form longer grain and a larger number of grains per stem with all three tested varieties. The mass of the grains in one stem of grains is higher with the optimum sowing period. Predel variety has the highest mass of the grain per stem of grains, followed by Progress variety and then by Victoria variety
