Паламарчук І.І. Вплив сорту та стимулятора росту рослин на врожайність і якісні показники продукції кабачка в умовах Правобережного Лісостепу. Наведено результати досліджень щодо реакції досліджуваних сортів кабачка на дію стимуляторів росту – біометричні показники рослин, врожайність та хімічний склад продукції в умовах Правобережного Лісостепу.

И.И. Паламарчук. Влияние сорта и стимулятора роста растений на урожайность и качественные показатели продукции кабачка в условиях Правобережной Лесостепи. В условиях Правобережной Лесостепи проведены исследования по изучению влияния сорта и стимулятора роста растений на урожайность и качественные показатели продукции кабачка. Установлено, что такие агроприемы способствуют улучшению биометрических параметров растений и продукции кабачка. Наибольшую урожайность получили при использовании стимулятора роста растений Фитоцид: у сорта Золотинка – 58,6 т/га, у сорта Чаклун – 89,6 т/га, что на 10,0 и 12,2 т/га больше в сравнении с контролем.

I.I. Palamarchuk. Effect of variety and plant growth stimulator on yield and quality indicators of zucchini production in the conditions of Right Bank Forest-Steppe zone. Zucchini is a valuable vegetable plant, in recent years, attracts attention due to its earliness, high yield, diet qualities and cold-resistance. In Ukraine, zucchini are grown annually on the area of about 24 to 28 thousand hectares, while the gross harvest of fruits is about 450 - 500 thousand tones. Increase of productivity and product quality improvement can be achieved through the introduction of new agronomic measures including the use of stimulants of plant growth, which can affect the yield formation of crop plants. Therefore, in conditions of right Bank Forest-steppe zones was conducted the experimental work, the purpose of which was to study the influence of variety and plant growth stimulator on yield and the quality of zucchini production. In the studies it has been established that biometric indicators of plants, particularly the length and thickness of stem, number and leaf area, the amount and quality of the harvest depended on the varietal characteristics of the squash and plant growth stimulator. Favorable conditions for plant growth developed during the application of growth stimulator Phytocide. So, the area of leaves and their number in the phase of technical maturity was at the level: variety Zolotinka – 31,8 PCs./plant, and 17.2 thousand m2/ha, variety Chaklun – 30,5 PCs/plant and 17.0 thousand m2/ha, in accordance. The yields indicate that the best conditions for its formation was created with the use of a growth stimulant Phytocide: variety Zolotinka - it was 58.6 t/ha, variety Chaklun up to 89.6 tons/ha, which is 10,0 t/ha and 12.2 t/ha more than control variant. The greatest number of fruit in both of the studied cultivars were characterized by a variant with application of growth stimulator Phytocide – 14,7-22,4 PCs./plant, which is 2.0-2.5 PCs./plant more plants from the control variant. As a result of researches it is established that biometric indicators of plants, the period of admission and the amount of harvest of zucchini was influenced by varietal characteristics, plant growth stimulants. On average over the three years of studies in variety Zolotinka variety Chaklun and the highest yield was with the application of growth promoters Vitasim and Phytocide, which provided the increase in yield of 7.9- 12.2 t/ha, in accordance.
