Efficiency of joint application of microfertilizers and plant protection products on bread winter wheat crops

Abstract

Aim. To determine yielding capacity and economic efficiency of joint application of microfertilizers and plant protection products on winter wheat crops in the Right-bank Forest-Steppe of Ukraine.Materials and methods. The researches (2012-2014) were conducted on the fields of the V.M. Remeslo Myronivka Institute of Wheat of the National Academy of Agrarian Sciences of Ukraine on commodity crops of bread winter wheat with varieties Kolos Myronivshchyny, Myronivska storichna, Natalka and Yuviliar Myronivsky treated with microfertilizers together with plant protection products in the IV, VIII and X stages of organogenesis. The treatment was carried out with microfertilizers Tseovit Micro Grain and Tseovit the Ovary Plus (1 l/ha) together with fungicide Falcon 460 EC (0.5 l/ha) and insecticide Karate Zeon 050 CS (0.2 l/ha). The accounting area of plots treated with fertilizers was 10 m2 in four replications. Agrotechnics in the experiments was common in the Right-bank Forest-Steppe of Ukraine. The crop was harvested by “Sampo-130” combine and recalculated to standard (14%) grain moisture.Results. Resulted from the studies conducted in 2012-2014 it was found that at joint application of microfertilizers and plant protection products during spring-summer vegetation of bread winter wheat the highest yield was obtained when processing crops in the VIII stage of organogenesis. During the years of research, yielding capacity of the varieties in average increased by 1.07–1.15 t/ha as compared with the control.Calculations show that the level of profit for the varieties during years of the research increased in average by 1257-1958 UAH/ha in comparison with the control. The highest profit level (9736–10041 UAH/ha) was obtained from the application of microfertilizers Tseovit the Ovary Plus (1.0 l/ha) and Tseovit Micro Grain (1.0 l/ha) together with plant protection products in the VIII stage of organogenesis, thus exceeding the control by 1653–1958 UAH/ha.When using microfertilizers on elite winter wheat crops, the profit would increase by 3500-4700 UAH/ha in comparison with the control.Conclusions. The use of microfertilizers together with plant protection products on winter wheat crops during the spring and summer vegetation makes it possible to increase yielding capacity of 1.07 to 1.15 t/ha and to increase the net profit from the additional grain by 20–24%.
