RESEARCH ON GARLIC FERTILIZATION TECHNOLOGIES

Abstract

Trading, in addition to other agrotechnical measures – crop rotation, tillage, sowing, crop care, etc. – is considered the most effective means of improving the yield of plants and the quality of the harvest. However, the effectiveness of fertilizers is determined by many factors: the physicochemical properties of the soil, the level of fertilization, the ratio of food elements, the time of fertilization, weather conditions, methods of fertilizing, the quality of work, etc. Therefore, one of the most important and difficult tasks of farmers is the rational provision of plant nutrition. To increase the efficiency of fertilizers, fertilizing technologies are constantly being improved, and the quality of fertilizers is being improved. The article presents the results of studies on the application of granular organic and mineral fertilizers when fertilizing garlic. The study was carried out on 2 ha of garlic field at selected driving speeds of 8, 10, 12 and 14 km h^-1 by centrifugal single-disc fertilizer spreader. According to the results of the study, it was found that when fertilizing garlic at the rate of 1000 kg ha^-1 with organic granular fertilizers and at the rate of 300 kg ha^-1 ammonium nitrate, the unevenness of fertilizer scattering was the same on both sides of the spreader. However, the transverse application distance of organic granulated fertilizers was less than that of mineral ones. Organic fertilizer was more damaged in the form of granules, especially at driving speeds of 12–14 km h^-1.
