The quality of spring wheat and barley grain under the influence of protective-stimulating preparations in the conditions of the forest-steppe zone of the Trans-Urals

Abstract

The purpose of the research is to study the effect of the fungicide Lamador and the humic preparation Rostok on the quality of spring wheat and spring barley in the conditions of the northern forest-steppe of the Tyumen region. According to the yield, we found that pre-sowing seeds treatment with Lamador protectant and joint treatment with Rostock contributed to an increase in yield by 0.70 t/ha of spring wheat and 0.15 t/ha of spring barley, in the option with the pre-sowing seeds treatment with Lamador protectant and Rostock preparation by 0.90 t/ha and 0.10 t/ha. The highest yield of spring wheat was noted in the third option – 4.10 t/ha, of spring barley in the second option – 3.52 t/ha. An increase in the thousand kernel weight was noted in the crops under study. The highest thousand kernel weight was observed for spring wheat and spring barley in the third option – 30.2 g and 54.3 g, respectively. The maximum protein content in the spring wheat grain was noted in the third option –13.3%, which is higher than the control option by 1.3%, for spring barley we also noted protein increase by 0.4-0.5%. Thus, the experimental application of the fungicide Lamador together with the preparation Rostok for wheat seeds treatment demonstrated a positive effect of the protectants on plants in the agro-climatic conditions of the forest-steppe zone of the Tyumen region and contributed to an increase in crop yield by 28% for spring wheat and 4% for spring barley, which proved the need for their use in the plant protection system, to increase the productivity and quality of the grain obtained.

Comparative analysis of segetal vegetation in different climatic zones of the Northern Trans-Urals

“…Weeds cause significant and diverse damage to spring wheat crops, which is the main food crop [7]. They absorb moisture and nutrients from the soil, inhibit the processes of photosynthesis, shading cultivated plants, reduce soil temperature, and have a negative allelopathic effect [8].…”

Biological treatment of plant waste water

“…Agriculture as an economic activity is based on meeting the needs of the population for fresh and nutritious food, but is also one of the sources of pollution of the components of the environment [1][2][3][4][5][6][7]. At present, the negative impact of agricultural production on the environment, one of which is untreated wastewater [8][9][10][11][12][13][14][15][16][17], is advancing.…”

Species and quantitative composition of weeds in wheat agrophytocenosis in the conditions of the forest-steppe zone of the Trans-Urals

“…The competitive ability of agricultural crops depends on many factors, which include, first of all, the biology of cultivated plants, the speed of their development, layering, stem density, and the power of the aboveground mass. The agricultural technique of cultivation is also important: the predecessor, the timing and methods of sowing, the system of fertilizers and chemical protection [10][11][12][13][14][15]. The purpose of the research: to analyze the species and quantitative composition of weeds in wheat agrophytocenosis.…”
