| Abstract | Objective. To determine the formation of productivity of different varieties of parsnip in the conditions of the Right-Bank Forest-Steppe under conditions without irrigation. Methods. Field, measurement, calculation-comparative, analysis, statistical. Results. As a result of the conducted studies, it was found that the yield of root crops varied significantly depending on the variety of parsnip. Thus, the highest yield was obtained when growing the variety of parsnip Gurman – 58.0 t/ha with a stability index of 0.90. In the variety of White Stone, this indicator was 35 % lower – 42.9 t/ha. The lowest yield was obtained when growing the Kamo variety – 26.3 t/ha or 2.2 times compared to the Gurman variety with a stability index of 0.66. When growing the Guernsey, Krugly and Kulinar varieties, the yield was within 31.3–37.5 t/ha. Studies show that the weight of the root crop varied from 167.7 to 230.8 g depending on the parsnip variety. The highest weight was obtained when growing the Gurman variety – 230.8 cm with a shape index of 8.2. Root crops with a round shape were obtained when growing the Krugly variety of parsnip, since the shape index was 2.9 with a root crop weight of 191.3 g. In the variety Kulinar, this indicator was at the level of 5.2, and in the varieties Bily Kamin, Guernsey and Kamo the shape index was the highest – 8.8–9.8, which indicates a large length of the root crop. Conclusions. In the conditions of the Right Bank Forest Steppe, the highest yield was obtained when growing the parsnip variety Gurman – 55.1–60.9 t/ha with a stability index of 0.90. At the same time, the shape index was at the level of 8.2. The water content in the root crops is 84.1 %, carbohydrates – 9.0, dietary fiber – 4.5, protein – 1.5, ash – 1.4 and fat – 0.5 %. In the varieties Kulinar and Krugly, the shape index is 5.2 and 2.9, respectively, with a yield of 33.7–39.4 t/ha. Therefore, it is advisable to use these parsnip varieties in breeding to obtain forms with round root crops. | ||
