Management of Agrophysical Soil Properties, Plant Growth and the Formation of a Potato Yield with Early and Double-yielding Culture by Optimizing Row Spacing and Maintenance Measures in Southern UZBEKISTAN

Abstract

This article presents the results of effect of different row spacing and planting care methods on the water-physical properties of the soil, on plant growth and development, on the formation of aboveground and underground parts, and on potato productivity. It was revealed that when cultivating medium-early potato varieties in early and double-yielding crops in southern Uzbekistan, to obtain 25-30 t/ha and higher marketable yield, it is advisable to plant tubers according to a 90x15 cm scheme and to care for planting during the growing season, performing loosening and hilling once to a depth of 18 cm and 2 times at 23 cm with a protective zone of 8-10 cm with an “Amak” milling cultivator or a “KRN-2.8A” cultivator with additional devices installed.
