STUDY OF TECHNOLOGICAL METHODS OF GROWING CARROTS GROWING IN THE CONDITIONS OF THE RIGHT BANK

The studied variety and hybrid, as well as sowing dates influenced the duration of interphase periods of table carrot plants. The interphase period "sowing – mass seedlings" was the longest during the sowing period of the third decade 03: in the variety Shantаne KL – 36 days, which is 3 days longer than the control and 12 days – from the sowing period of the third decade 04, in the hybrid Bolivar F1 – 34 days, which is 3 days longer than the control and 12 days longer than the sowing period III decade 04. The period of root formation – technical maturity lasted from 80 to 92 days. It was shorter during the sowing period of the third decade 04: in the variety Shantane KL it is 12 days shorter than the control, in the hybrid Bolivar F1 it is 8 days shorter than the control. The longest this interphase period was in table carrot plants sown during the sowing period of the third decade 03, in the variety Shantane KL – 92 days, in the hybrid Bolivar F1 – 89 days. Plants had the longest vegetation period during the sowing period of the third decade 03: in the cultivar Shantane KL – 126 days, in the hybrid Bolivar F1 – 124 days, which is 4 and 3 days longer than the control variants. The highest yield of table carrots was obtained during the sowing period of the third decade of March: in the variety Shantane KL – 41.4 t / ha, in the hybrid Bolivar F1 – 47.1 t / ha, where the increase relative to controls was 4.9 and 5.2 t / ha, respectively. The significance of this difference was confirmed by the results of analysis of variance. The studied variety and hybrid were characterized by high marketability. In general, the marketability in the experiment was influenced by varietal characteristics, as well as the timing of sowing of carrot seeds. The marketability of table carrots, depending on the variant of the experiment was 77.2 - 88.0%. The highest marketability indicator was characterized by the roots of the Bolivar F1 hybrid during the sowing period of the third decade of March – 88.0%, which is 2.7% higher than the control. According to the results of biometric measurements, the influence of sowing dates on the biometric parameters of table carrot roots was revealed. The main indicator that affects the size of the crop is the weight of the root crop. The highest mass of root crops was recorded in plants sown during the sowing period of the third decade of March: in the variety Shantane KL – 122 g in the hybrid Bolivar F1 – 128 g, which is more than the control variants by 23.7 and 25.5 g, respectively. In terms of root diameter, this indicator was the largest during the sowing period of the third decade of March: in the cultivar Shantane KL – 6.2 cm in the hybrid Bolivar F1 – 6.6 cm, which is 0.4 cm higher than the control variants, respectively. According to average data, the greatest length of root crops was observed during the sowing period of the third decade of March, where the increase relative to control was 0.2 - 0.4 cm, respectively.
