Abstract

In order to evaluation of different SOWING AND HARVESTING DATEs effect on yield and quality of monogerm SUGAR BEET seeds, an experiment was conducted in the form of split plot based on completely randomized block design with four replications in Ardabil Agriculture Reaserch Station in 2003. Four sowing dates(10 and 25 of March, 9 and 24 of April) were located in main plots and harvesting dates including 15, 30, 45 and 60 days after 50% flowering were located in sub-plots.The experiment results showed that germination percent, normal seedlings percent, seed effective filling period and seed filling rate were affected significantly(p<0.05) by sowing date. In this study, all of the traits were affected significantly by the harvesting date. According to the results, seed effective filling period decreased significantly with delayed sowing and early harvesting. Saleable seed yield and shattering rate was increased above 2th harvest (30 days after flowering).There was significant positive relationship (r=0.623**) between saleable seed yield and seed filling period. The highest germination rate and normal seedlings were obtained similarly at first sowing date with 55.833 and 80.277 percentage, respectively, and the lowest of them were obtained in second and third sowing dates. Electrical conductivity of SUGAR BEET seed extraction and germination rate was diminished and increased significantly, as harvesting date was delayed, respectivly. Germination percent, germination rate and normal seedlings showed positive and significant correlation with maximum seed weight.
