aref2 Results of zonal sowing dates of barley affecting the development of root rot are researched. If you delay the timing of sowing root rot strongly stroked all the organs of the plant. Moderately wet weather aggravates the development of dark-brown spotting (DBS) in late sowing. The highest degree of development of the disease is marked on the coleoptile at all sowing. Epicotyl less often was affected by root rot. Progression of the disease in this variant does not exceed 10.3%. Progression of the disease in the primary roots in the tillering stage was higher at late planting dates and was 26.2%. Reduction of disease development on epicotyl by 3.6%was observed at a medial sowing date. In sufficiently wet and the optimum years planting date had little influence on the development of DBS. In dry conditions at slightly later time of sowing manifestation of the disease has a significant influence on the development of DBS in barley. The greatest increase was obtained and the yield of barley at sowing it in the early stages due to the increase of productive stems and grains made. Decrease in weight of 1000 grains at late planting dates was due, above all, a strong manifestation of root rot in a period of growth and development of barley. The highest increase in yield, which was 12% and 7% compared with the control, has been obtained in the early and medium sowing terms respectively. It is concluded that all barley organs most severely affected at late planting dates.
