Abstract

Aim. To establish the influence of the non-transplant method of growing carrot seeds on overwintering and development of carrot plants, seed yield and its quality. Methods. Field, laboratory, computational and statistical. Results. The results of the effectiveness of the introduction of a direct method of growing certified seeds of carrots of the Yaskrava variety in the Forest Steppe of Ukraine were presented. Data on overwintering of seed plants of carrots, biometric parters of seedlings, seed yield, its varietal purity and conditional indicators depending on the timing and rate of sowing, the introduction of pre-winter hilling of plants with soil were presented. The highest density of plants after overwintering is formed during sowing in the first decade of August with pre-winter wrapping at a density of 600 ths. seeds/ha (73.8 ths. plants/ha). The introduction of a direct method of growing carrot seeds causes the formation of seedlings with higher biometric parameters (plant height, number of shoots of the first order, umbrella diameter), but there is a reduced varietal purity to 97.4-97.9%. When sowing carrot seeds with a norm of 600 ths. seeds/ha in the first decade of August and conducting pre-winter shelter, the maximum level of seed yield (440 kg/ha) is formed. Conclusions. The maximum overwintering of carrot plants was obtained by sowing seeds in the first decade of August with pre-winter soil wrapping (64.9–73.8 ths. plants/ha depending on the sowing rate). For sowing carrot seeds with a sowing rate of 600 thousand plants / ha in the first decade of August, more developed carrot seeds with a height of 94.3 cm were formed; the number of shoots of the first order is 9.5 pcs./plant, the diameter of the central umbrella is 12.3 cm. Conducting a field inspection showed that the varietal purity of carrots was at the level of 97%, and the obtained carrot seeds were in good condition and complied with DSTU 7160: 2010.
