Aspects of using interspecific hybridization of goats

Abstract

Relevance. One way to increase the productivity and quality of potatoes is to use biological products. They have the ability to influence the immune potential of plants, disease resistance, which in turn affects the yield and quality of tubers.

Methods. We have studied the effect of two biological preparations Flavobacterin and Mizorin, as well as their combined effect on the growth and development of potato plants.

Results. Treatment with biological products at different stages of development increased the rate of development of potato plants during seedlings by 10-20%, but in the phase of budding and flowering, these differences were smoothed out. The highest yield increase of 1.3 t/ha was noted in the variant with joint processing (Flavobacterin + Mizorin), where the yield was 17.8 t/ha. The quality indicators of tubers treated with drugs did not have a significant impact, however, they significantly affected the prevalence of diseases. So, pre-planting treatment of potato tubers and treatment of potato plants during the growing season with biological preparations increases disease resistance during storage: mushroom from 0.7 to 4.0%. The safety share of healthy potato tubers was 80-95%, and 75% without treatment.
