Influence of Cultivation Technology on the Growth and Development of Sweet Corn Plants of Hybrid Moreland F1

Abstract

The results of research on the influence of plant standing density and level of mineral fertilization on growth and development of sweet corn plants of hybrid Moreland F1 on sod–podzolic soils have been presented. The change in influence degree of technological factors on the height of sweet corn plants in different periods of the crop growth and development has been established. It was determined that the longest vegetation period had the crops of sweet corn grown under conditions of full mineral fertilization and maximum plant density of 80.000/ha – 80.3 days, and the shortest one was on the variant with unfertilized background and plant density of 60.000/ha – 73.2 days. Increase of mineral fertilizer dose contributed to better growth of sweet corn than in variants without mineral fertilizers. Increase of plant density up to 80.000/ha led to unnatural stretching of plants (over 190 cm). It was determined that the optimal plant height of the crops was at the density of 60 thousand/ha on the background of nutrition N135P90K125 + N60 + N30. The maximum average daily growth was characterized by sweet corn plants on the background of nutrition N135P90K125 + N60 + N30 with plant density 80.000/ha – 2.93 cm.
