PRESOWING SEED TREATMENT AND SEED RATES OF RED BEET
Researches were carried out to study the effect of soaking of beet seeds with hydroperitum solution and of grading combined with a seed rate on productivity of beet plants. It has been established that soaking of seeds with 0.4% hydroperitum solution improves their sowing qualities, positively affects the growth rates of beet plants, increases beet productivity by 10.4 t/ha, increases dry matter and sugar contents in roots by 1.2% and 1.0%, respectively, and reduces the content of nitrates by 169 mg/kg. It has been revealed that beet productivity depends on not density of planting but the weight of seeding material. Sown at 9 kg/ha seed rate in various fractions, beet productivity was within an experimental error, 40.9 - 43.4 t/ha. Sown at seed rate of 700 ths viable seeds per ha, productivity without grading made up 39.1, small fraction 35.2, average 41.7 and large 44.0 t/ha.
