FEATURES OF SUNFLOWER OF STRAWBERRY DEPENDING ON ADAPTIVE GROWING TECHNOLOGIES

Abstract

When growing strawberries, we must pay special attention and make the transition to less harmful technologies in order to obtain environmentally friendly products. This position minimizes the possibility of using mineral fertilizers or inorganic protection in favor of organic methods or substances of biological nature that do not have a harmful aftereffect. This is of particular importance when mulching the soil with various materials, as the most advanced method of increasing the productivity of strawberry stands. Therefore, the selection of the most adapted and improved technologies for growing environmentally friendly strawberries determines the purpose of our research. The highest results were achieved in the growth productivity of strawberries when it was grown using environmental technology with mulching the soil together with black agrofibre and straw. Moreover, the average results of the assimilation surface of strawberries amounted to 28.4 thousand m2 / ha for the Dukat variety, and 29.1 thousand m2 / ha for the Malvina variety. Such results practically exceeded the data of the control variant twice. A significant increase in the number of tendrils on the strawberry bushes was about 30%. At the same time, the number of peduncles in the bushes increased by 15%. On the whole, according to the experiment, the results for strawberry varieties varied within 6.7–7.3 pcs / bush. A significant difference compared with the control option was 1.4–1.8 pcs / bush. We have achieved a 35% increase in strawberry berries when mulching the soil with black agrofibre together with straw as part of environmental cultivation technology. On average, over the years of research, the strawberry yield for the Dukat variety was 21.5 t / ha, and for the Malvina variety - 15.5 t / ha. At the same time, commodity quality of berries increased to 93.4%. The use of intensive (traditional) and biological technologies for growing strawberries, in terms of productivity, was significantly inferior to environmental technology, like other mulching materials inferior to black agrofibre.
