INFLUENCE OF VARIOUS FEATURES ON PRODUCTIVITY AND QUALITY OF FOOD PRODUCTS IN THE CONDITIONS OF FOREST-STEPPE OF RIGHT-BANK UKRAINE

The results of studies of the study of yield and quality of zucchini production are presented depending on the variety and hybrid. It was established that the yield and quality of the products depended on the variety and hybrid and varied according to the weather conditions for the years of research. Among the studied varieties, the highest yield was formed by Chaklun – 77.5 t/ha, and Gribovsky 37 (control) – 58.7 t/ha, which is 18.8 t/ha less. Variety Zolotinka was characterized by a significantly lower yield, it was lower compared to the control of 10 t/ha. Among the hybrids, the Iskander F1 hybrid yielded the highest yield – 53.8 t/ha, which is 6.1 t/ha more compared to the control. The greatest number of fruits characterized plants of the Chaklun variety – 21.2 pieces/plant, which is 4.5 pieces/plant more control (Gribovsky sort 37). Among the hybrids this indicator was greater in the Iskander F1 hybrid – 16.0 p/plant, which is 2.2 pcs/plant more control. The greatest weight was formed by the fruits of the Zolotinka variety – 303 g and Chaklun – 308 g, which is higher than the controls by 9.0 and 14.0 g. Among the hybrids studied, the largest indicator was on control – 291 g. The highest content of dry matter was noted in the Zolotinka variety – 5.6 %, which is 0.1 % more control. In other studied varieties, the dry matter content was at the level of 5.4-5.5%. Among the hybrids, the highest content of dry matter contained the fetuses of the Iskander F1 hybrid – 5.6%, which is 0.3% more than the control variant. Variety Zolotinka and Aliya F1 hybrid were characterized by the highest sugar content, respectively, 2.3 and 2.1%. The lowest indicator was in Gribovsky 37 (control) – 1.2%. The content of nitrates in the fruits of varieties and hybrids was within the maximum permissible level and amounted to 54.0-181 mg/kg. The smallest content of nitrates among the varieties was characterized by a control variant (Gribovskii grade 37) – 54.0 mg/kg. The highest content of nitrates was found in fruits in the cultivar Koldun – 181 mg/kg. Among the hybrids, the Alii F1 and Kavili F1 hybrids were the smallest and the largest nitrate content, 87.5 and 157 mg/kg, respectively
