Influence of the use of liquid fertilizers on the quality indicators of grain of the spring wheat variety DalGAU 1

Abstract

Relevance. Recently, liquid fertilizers have been increasingly used in the technology of cultivating spring wheat. They are ideal for spraying on the surface of a field with cereals and other plants. Compared to solid fertilizers, the advantages of automated control of their distribution over the field, the possibility of joint application of herbicides, insecticides, microelements.Methods. Field experiments to study the influence of methods of using liquid fertilizers were conducted at the experimental field of the Far Eastern State Agricultural University in the southern agricultural district of the Amur region (Blagoveshchensk district, village of Gribskoye). The laying of the field experience was carried out according to the method of B.A. Dospekhov in fourfold repetition. The registered area of the plot is 16 m², the placement is randomized, the previous crop is soy. The studies included field and laboratory observations.Results. It was found that when using liquid fertilizers, the weight of 1000 seeds changed according to the variants of the experiment with the use of fertilizers relative to the control without the use of fertilizers from 1.5 to 4.9 g. Сombined use of Nertus Start and Photosynthesis — 696.6 g/l, which is higher than the control by 48.7 g/l and the background by 19.2 g/l. The maximum value of the natural grain weight for an average of four years was in the variant with the combined use of Nertus Start and Photosynthesis — 696.6 g/l, which is higher than the control (by 48.7 g/l) and background (by 19.2 g/l).
