| Summary: | There is a great shortage of trace elements in the soils of our country, which does not justify the biological potential of the productive indicators of the main crops.
The research objective is the scientific substantiation of the choice of the most effective way of applying complex liquid fertilizers with microelements in chelated form to form the density of agrocenosis, seedlings qualities and biochemical composition of spring wheat seeds.
It was established that, on average, over two years of research, the field germination of spring wheat against the background of natural fertility was in the range of 73.8-78.4%, and against the background of the application of nitrogen-phosphorus-potassium fertilizer it amounted to 73.6-79.3%. The largest number of plants remained for harvesting was noted both against the background without fertilizer application and against the background of mineral nutrition in the variants with seed treatment with Megamix-seeds and Megamix-Profi in the tillering and heading stages – 386 and 388 plants per 1 m2.
Micronutrient fertilizers influenced the weight of 1000 seeds, germination energy, laboratory germination and growth power. When growing this crop against the background of N16P16K16 application, the weight of 1000 seeds increased by 10.1% according to the experimental variants, germination energy – 9.4%, laboratory germination by 6.9%, weight of 100 sprouts – by 17%, and sprout length – 18.9%.
The biochemical composition of the grain shows a supply of the following nutrients: protein, nitrogen, phosphorus and potassium, the largest amount of which was accumulated in spring wheat grain grown during the treatment of seeds and crops with fertilizers Megamix-seeds and Megamix-Profi. |
