The use of protein hydrolysate obtained by deep processing of meat raw materials for foliar feeding of soft wheat and reducing the intensity of disease development

Annotation

On 25 varieties of soft wheat, the effectiveness of the use of protein hydrolysate obtained from by-products of meat raw materials by deep processing using microconcentrations of chemical reagents was determined for foliar feeding and reducing the intensity of diseases. In field conditions, an increase in wheat yield was found in 72% of wheat varieties, in relation to control samples. A significant increase in the indicator was detected in samples Siberian 21, k-66269 ‒ by 143.1% (2017); Tulaykovskaya 108, k-65452 ‒ by 103.0% (2017); Ural cuckoo, k-66267 ‒ by 87.9% (2017); Amur krasnokoloska, k-32095 ‒ by 69.9% (2018–2019); Krasnoufimskaya 110, k-65478 ‒ by 59.2% (2018–2019). A significant increase in the increase in the vegetative mass of soft wheat was detected in varieties Leningradskaya 97, k-62935 – by 41.9% and k-32666 – by 39.1%. The increase in yield and disease resistance of wheat varieties was different. The increase in thevalues of the studied parameters after treatment with protein hydrolysate was associated with a change in the morphological characteristics of plants and the structure of the crop. Treatment with protein hydrolysate, which stimulates plant growth, helped to reduce the development of wheat diseases. The tendency of a statistically significant decrease in the intensity of root rot development at P <0.05 was revealed in the maximum number of wheat varieties (44%). In the Ural Cuckoo variety, k-66267, the development of root rot was not detected (in the control – 50%) and symptoms of the pathogenesis of powdery mildew in the Tyumenochka variety, k-66271 (in the control 11%). The Tulaykovskaya 108, k-65452 variety showed a decrease in the development of septoria-pyrenophorous spotting by 36.0% and an increase in total nitrogen in wheat leaves by 199.8% in relation to control samples. Foliar spraying of plants with a protein growth stimulator caused an increase in total nitrogen in wheat leaves in 92% of samples by an average of 84.6%.
