Influence of sowing dates on the phytosanitary condition and yield of rye and triticale in organic farming
Keywords:
organic farming; rye; triticale; time of sowing; yieldAbstract
During the period 2012-2014, in the Institute of Agriculture – Karnobat, in а certified organic farming was conducted field experience with rye and triticale. The aim of the experiment was to investigate the impact of sowing dates on crop productivity and to compare the level of weed infestation, diseases and pests. The crops were sowed in three terms: 1st - in late September, 2nd - in mid-October and 3rd - in early November. For organic rye, the best sowing date was in October. The yield was the highest and the weeds and the density of the pests were lower. For organic triticale, productivity was highest when the crop was sown in September and phytosanitary conditions were better when sowing in October.
