INFLUENCE OF MICROELEMENTS ON INCREASING OF THE RED CLOVER SEEDS YIELD IN THE CONDITIONS OF THE REPUBLIC OF THE NORTH OSSETIA-ALANIA

Abstract

In the last years of our century, new non-traditional farming systems have become widely popular in our region, and therefore various methods of feeding crops are widely used that can increase both seed yields. This paper presents some aspects of the study of various types of trace elements and their combination, which can also increase the yield of meadow clover seeds. In 2021-2024, studies on the use of micro fertilizers on meadow clover crops were conducted in the forest-steppe zone of the Republic of North Ossetia-Alania. The purpose of the work is to improve an element of the technology of cultivation of meadow clover, aimed at improving the productivity of the seed harvest through the use of trace elements. It has been established that the use of micronutrients (boron, molybdenum). Boron has also been found to increase plant resistance to drought and elevated temperatures. Boron plays a particularly significant role in liming acidic podzolic soils. The use of lime to reduce soil acidity improves conditions for the development of plants, but at the same time, under the influence of calcium carbonate, boron becomes less accessible to plants. The use of boric fertilizer in the year of clover seed production resulted in an increase in yield over an average of 3 years by 21.6 kg/ha, or by 20.3%. At the same time, in the arid year of 2022, the increase in the yield of clover seeds from the use of boric fertilizer in the medium-cultivated area was minimal – 9.2 kg/ha, and in the wet year of 2024, the highest was 37.0 kg/ha in the less cultivated area. The use of boron against the background of phosphorus-potassium fertilizers resulted in an average yield increase of 34.6 kg/ha, or 32.6%, over the years of the experiments.
