MONITORING THE USE OF AgroZAR MICROFERTILIZERS IN SOYBEAN CULTIVATION

Abstract

The aim of the work was to study the effectiveness of AgroZar microfertilizers in soybean cultivation. To achieve the goal, the following tasks were solved: - evaluate the impact of AgroZar microfertilizers on the formation of crop density and the survival rate of soybean plants; - establish the dynamics of the height of soybean plants under the influence of AgroZar microfertilizers; - to investigate the effect of AgroZar microfertilizers on the photosynthetic productivity of soybean crops; - evaluate the impact of AgroZar microfertilizers on the structure of soybean productivity elements; - establish the effect of AgroZar microfertilizers on soybean seed productivity; - to investigate the quality of soybean seeds under the influence of AgroZar microfertilizers; - conduct an economic assessment of the feasibility of using AgroZar microfertilizers in soybean cultivation. The use of AgroZar microfertilizers had a positive effect on both the field germination of soybean seeds and the pre-harvest density of soybean crops. The highest field germination – 80.56% was provided by the variant with the use of potassium humate at the rate of 1 l/t of seeds for pre-sowing treatment of soybean seeds, and the highest density of soybean plants before harvesting (501.3 thousand/ha) – the variant using AgroZar microfertilizer Soy is normally 1 l/ha. AgroZar microfertilizers have a positive effect on the formation of the height of soybean plants. In particular, the highest height of soybean plants was in the version where AgroZar Soya microfertilizer was applied at the rate of 1 l/ha, and was 47.8 cm, which is 4.6 cm more than in the control. The best indicators of the structure of elements of soybean productivity were provided by the variant where AgroZar Soya microfertilizer was applied. In this variant, the height of the attachment of the lower bean was 10.9 cm, the number of beans on one plant – 15.9 pcs., the number of seeds in a bean – 1.91 pcs., the number of seeds from one plant – 30.9 pcs., the mass of seeds from one plant – 5.56 g, and the weight of 1000 seeds – 184 g. The highest yield of soybean seeds was obtained in the variant where AgroZar Soya microfertilizer was used at the rate of 1 l/ha. In this option, the yield of soybean seeds was 2.63 t/ha, which is 27% higher than in the option where microfertilizers were not applied. The best indicators of economic efficiency were provided by the variant where AgroZar Soya microfertilizer was applied at the rate of 1 l/ha. In this option, the cost of gross production was UAH 31,560/ha, conditional net income was UAH 21,860/ha, the cost of grown products was UAH 3,688/t, and the profitability level was 69.3%.
