Efficiency of liquid humic fertilizer and herbicidal treatment in spring soft wheat (Triticum aestivum L.) cultivation technology

Abstract

One of the ways to increase the yield and quality of crop production is the development and use of agricultural technologies with minimal environmental impact on the environment. An effective method of such technologies is pre-sowing seed treatment and foliar fertilization of plants with humic substances. Therefore, the effect of the liquid complex humic fertilizer “Healthy Harvest” (LCHF) was conducted on the basis of the SEC “Vishnevsky” in the Belovsky district of the Kemerovo region during 2019–20 with an application rate of 0.5 L/ha and 1 L/ha in tank mixtures with the herbicide Magnum Super, VDG (application rate 10 L/ha). It was found that in field conditions the LCHF provided a significant decrease in the phytotoxicity of the herbicide Magnum Super, VDG (tribenuron-methyl + metsulfuron-methyl). Under the influence of the LCHF with the application rate of 0.5 L/ha and 1 L/ha, the yield increase was 2.38 t/ha and 2.61 t/ha, respectively; the antidote effect with the application rate of 0.5 L/ha gives an increase in yield in 1.26 times. LCHF were able to reduce the phytotoxic effect of the herbicide Magnum Super, VDG on wheat plants, increase the resistance of the crop and, thereby, preserve the yield. The use of the LCHF in a tank mixture with the herbicide Magnum Super, VDG made it possible to remove the of herbicide negative effect, which had a positive impact on the mass fraction of protein, raw gluten, glassiness and grain nature.
