INFLUENCE OF ORGANIC, MACRO, MICROFERTILIZERS AND GROWTH REGULATOR ON PHOTOSYNTHETIC ACTIVITY OF CROPS, YIELD AND QUALITY OF CORN WHILE CULTIVATED FOR SILOS ON SOD-PODZOLIC LIGHT LOAMY SOIL

Abstract

Corn is the main silage crop in the agriculture of the Republic of Belarus. The main technique aimed at achieving this goal is the use of mineral and organic fertilizers. To form high yields, corn plants require a significant amount of nutrients throughout the growing season. Thus, these studies are relevant. The use of fertilizers significantly influenced the increase in the yield of green mass of corn, and the content of necessary macro- and micro-elements in it. Promoted a positive photosynthetic activity of crops. The improvement of all these indicators is affected not only by the correctly selected doses of organic and macronutrient fertilizers, but also by micronutrient fertilizers and growth regulators. The best fertilizer system to obtain a high and high-quality corn silage crop during the experiments was organomineral with foliar top dressing with zinc-containing micronutrient fertilizers.
