Changes in the Yield and Quality Grain of Soybean When Using Liquid Fertilizers

Abstract

On meadow chernozem-like medium-thick soils of the southern agricultural zone of the Amur region, the influence of the methods of using liquid fertilizers from the Berluga company (Hungary): Nertus Start, Fotosintez and Bor on the productivity and quality grain of soybeans was studied. The research was conducted in 2018–2020 on the experimental field of Far Eastern State Agrarian University in the village of Gribskoie in Blagoveshchensk district. The object of research was a soybean variety of an early ripe group Umka breeding by the FRC All-Russian Scientific Research Institute of Soybean. In the experiment, liquid fertilizers were used in two ways: Nertus Start when pre-sowing seed treatment and Nertus Fotosintez and Bor when treatment vegetative soybean plants in the budding phase. The positive effect of liquid fertilizer Nertus Bor in the treatment of vegetative plants of soybeans and Nertus Start in the pre-sowing treatment of seeds on the yield of soybean has been established. In these variants, the maximum productivity was obtained over the years of research. Results of field studies in the conditions of 2018–2020 on meadow chernozem-like soil of the southern agricultural zone of the Amur region show that feeding with liquid fertilizer Nertus Bor in the budding phase of soybeans contributes to an increase in the protein content in seeds for all years of the experiment. The greatest effect was shown by spraying vegetative soybean plants in the budding phase with liquid fertilizer Nertus Bor.
