SOIL MULCHING AS AN AGRICULTURAL METHOD FOR GROWING ZUCCHINI IN CONDITIONS OF RIGHT BANK FOREST-STEPPE

Abstract

It has been established that the mulching materials was carried out by influence on the biometric parameters of plants and the production of zucchini yield in the years of research. According to research results, the greatest length of stem in the flowering stage was observed in plants mulching soil with black agro-textile and plastic film, black perforated, varieties Zolotynka – and 63,6 – 61,3 cm, varieties Chaklun and 62,4 – 61,0 cm, where the increase relative to the control was 3,3–5,6 cm. The greatest number of leaves at flowering stage was observed in varieties Zolotynka for soil mulching with black agro-textile – 22,5 PCs/plant, black perforated polyethylene film – 24,0 PCs./plant, which is 4,8 – 6,3 PCs/plant more of the variant without mulch. The variety Chaklun, a significant difference was on the options for soil mulching with black agro-textile – 23,0 PCs/plant and black polyethylene film perforated to 23,5 PCs/plant, 5,4 and 5,9 PCs/plant more control. An important indicator in evaluating biometric parameters of the zucchini is leaf area. The highest it has been for mulching the soil with black agrotextile and plastic film, black perforated, varieties Zolotynka to 6,8 and 7,1 thousand m2/ha, varieties the Sorcerer – 8,2 and 8,5 thousand m2/ha, of 0,7–1,0 and 0,8–1,1 thousand m2/ha more control. Large productivity on average was noted for mulching the soil with black agro-textile and plastic film, black perforated, varieties Zolotynka – of 49,7 and 53,3 t/ha, 7,3 and 10,9 t/ha more control. The variety Chaklun all the studied variants had significantly higher yields, but the highest it has been for mulching the soil with black Agro-textile and plastic film, black perforated – between 90,0 and 97,8 t/ha, respectively, and 20,2 to 28,0 t/ha more in comparison with the control. The greatest number of fruits was noted for mulching the soil with black agro-textile and plastic film black perforated : y grade Zolotynka – 14,7–14,6 PCs/plant, varieties the Chaklun of 26,6–29,8 per PCs/plant. The highest fruit weight was observed in varieties Zolotynka for soil mulching with black agro-textile – 303 g, a polyethylene film, black perforated – 314 g sawdust and – 302 g, which is 15,0–27,0 g more control. The variety Chaklun large mass of the fetus had options for mulching the soil with black agro-textile – 305 g and black perforated polyethylene film – 319 g, which exceeded the control at 14-28 g. The diameter of the fruit greatly from the use of mulching materials did not change, but their use was noted a positive trend. So, for the sorts Zolotynka the diameter of the fruit for soil mulching with different materials grew by 0,1–0,3 cm, for a variety of Chaklun – 0,1-0,2 see. Key words: zucchini, variety, multi-valley material, biometrics, productivity.
