Efectiveness of Huminatrin application on grain crops in the foreststeppe of Novosibirsk Priobye region

Abstract

At present, it is of particular importance to further increase the yield and quality of grain crops under experimental conditions in Western Siberia. Of special meaning is finding new effective growth regulators and bio-fertilizers that promote ecological plasticity, resistance to environmental stressors and pests. The work aims to study the influence of the new biofertilizer Huminatrin on growth and development features, yield and quality of grain crops under conditions of increasing crop productivity in the northern forest-steppe of the Novosibirsk Priobye region. Experimental field was on the fields of JSC “Irmen” livestock breeding farm in Ordynsky district of Novosibirsk region. The authors determined that Huminatrin (a mixture of micronutrients and bacteria) provides an increase in leaf surface parameters in two varieties of wheat by 23% and in spring barley by 34%. The authors treated soil with Huminatrin before sowing in a dose of 2 l/t at operating-liquid flow rate of 10 l/t and during the growing season in the phases of tillering and earing in a dose of 1.5 l/ha (300 l/ha). It was shown that both wheat varieties and spring barley variety “Biom” significantly increased the yield on the background of Huminatrin. On average, the yield increased by 22%. When using Huminatrin, the authors observed an increase in the number of productive stems (up to 408 mg/m2), the number of grains in the ear (up to 32 pcs), weight of 1000 grains (up to 40.86 g). There was also an increase in gluten content - up to 34%; gluten deformation index was about 96. In addition, the authors note the reduction of plant infestation by brown rust to 28% against 47% in the control (water). Indicators such as weight of 1000 grains, weight of grains per plant, the number of grains in the ear form the quality of the crop. Application of Huminatrin allows to achieve high yield quality of two varieties: spring soft wheat and spring barley
