Effect of Biological Preparations on the Growth, Development, and Productivity of the Ranemo Potato Variety

This study investigates the effects of biological preparations on the growth, development, and yield productivity of the potato variety Ranemo. The research demonstrates that the application of biological products - Biodux, Zerebra Agro, and Biogrand - during pre-planting treatment and throughout the growing season, particularly at the early budding and flowering stages, contributes to obtaining high and high-quality marketable yields. The highest efficiency was observed with the use of the biological product Biogrand. When potato tubers were treated before planting at a rate of 200 ml/t, the yield reached 32.3 t/ha. Furthermore, foliar application during the growing season at a rate of 1000-1200 ml/ha resulted in yields of 37.6-37.8 t/ha. These results exceeded the control treatment (without biological preparations) by 10.5-10.7 t/ha, and surpassed the yields obtained with other biological products by 1.4-2.3 t/ha. The application of the biologically active preparation Biogrand under early planting conditions - combined with pre-planting treatment at 200 ml/t and foliar application during the growing season at the budding and early flowering stages at 1000-1200 ml/ha - ensures optimal plant growth and development, as well as significantly enhances productivity and overall yield.
