Effect of micronutrients on the peculiarities of growth and development of maize plants

Abstract

At the present stage of development of agriculture in Azerbaijan, when small farms are created everywhere in the country, differentiated approach to solving many problems of farming is of special importance. In the republic, natural fodder lands are unproductive, and in many farms pastures and hayfields are absent at all, so the main share of fodder is produced through field fodder production. Here a special role is given to high-yielding promising crops, such as corn. In grain and fodder production, corn in Azerbaijan occupies one of the first places among spring grain, leguminous and fodder crops. In increasing the production of grain and green mass of corn, as well as improving the quality of the harvest, mineral nutrition is of great importance. In the physiology of mineral nutrition an important role belongs to trace elements. For conditions of Mugani soils characterized by low content of mobile forms of microelements, it is of special interest to determine the influence of optimal norms, combinations and methods of using microfertilizers on maize productivity. For normal growth, development and formation of high yield of green mass and corn grain, a vital condition is a sufficient supply of plants with nutrients on ameliorated soils. In soils usually gross content of nutrient elements exceeds the needs of plants, but only a small part of them is soluble in soil moisture and available to cultivated crops in a certain period of their development. Therefore, it is necessary to know the content of macro- and microelements in the soils of the experimental plot. Soil analysis plays a major role in determining the level of plant nutrient availability.
