Effectiveness of foliar feeding puffiness of sugar beets on dark gray podzolic soils of Western Forest-steppe

Abstract

It is determined that under western Forest-Steppe of Ukraine conditions methods of soil tillage did not have a significant influence on the dynamics of the mass increase of sugar beets plants on dark grey podzolic light loamy soils. The processes of forming the mass of root crops and leaves during the growing season depended more heavily on the phases of growth and development of sugar beet and almost did not depend on the methods of cultivating the soil such as traditional deep plowing on 28–30 cm and shallow no-plow tillage on 14–16 cm. On July 15 we marked intensive growth of the mass of the leaves. Depending on the method of the main cultivation of soil and leaf feeding, the weight of the leaves was 1.6 times greater than the weight of the root crops. On August 15, the weight of the leaves reached its maximum, the ratio of the leaves to the root, depending on the method of soil cultivation and foliar feeding was within the range of 1.0–1.1. The record keeping of September 15 shows that the ratio between the leaves and the root crop, depending on the method of soil cultivation and leaf feeding, was within the range of 0.7. Significant differences in indicators, depending on the cultivation of the soil, were not recorded, the plants developed approximately at the same level. The foliar feeding is a measure that promotes the mass increase of root crops and assimilation leaf surface. The optimum is the use of a mixture of carbamide N4.62 kg a.i. + magnesium sulfate 1,67 кg. a.i. + microelements Crystallon, which provided the largest mass of root crops: on July 15 — 133–126 g, on August 15 — 239–233 g, on September 15 — 291–299 g, while harvesting — 312–303 g and joints respectively: 221–205 g, 258–240 g, 204–203 g, 178–176 g.
