Keywords: zucchini, growth, development, stages of development, yield

Abstract

The aim of the research. Study of growth, development and productivity of zucchini varieties depending on the variety and mulching material on the background of water-retaining Akvod granules in the conditions of the Right-Bank Forest-Steppe of Ukraine. Methods. Field, laboratory, statistical. Methods. Field,  laboratory, statistical. Results. According to the results of research in 2016 – 2018, zucchini varieties, depending
on the type of mulching material, on the background of water-retaining granules, formed different biometric parameters of plants, which varied depending on the phase of growth and development of plants and affected the yield of zucchini. Mulching materials influenced the onset of plant development phases and their duration. Findings. The influence of soil mulching on the duration of interphase periods of zucchini was revealed. The longest period of fruiting was characterized by the option of mulching the soil with a black perforated polyethylene film for 89–90 days. Mulching of the soil with black polyethylene film contributed to the formation of the best biometric parameters, in particular, the increase in leaf area in the phase of technical maturity was 3.9–7.2 thousand m2 / ha. For both varieties, the use of agrofiber and polyethylene film as mulching material increases the stem length by 2–19 cm, stem thickness – by 1.6-6.2 mm, the number of leaves – by 3.5–8.7 pcs / plant, leaf area – by 0.4-2.2 thousand m2 / ha. The combined use of water-retaining Akvod granules and mulching the soil provides a higher yield of zucchini. The largest increase in yield relative to control was provided by options for mulching the soil with black agrofiber and black perforated polyethylene film, the yield of marketable products increased by 12.3–21.9 t / ha for the variety Zolotinka and 26.1–35.0 t / ha for the variety Chaclun. The largest number of fruits is provided by mulching the soil with a perforated black polyethylene film (20.6–31.9 pieces / plant).
