The first seedlings were observed in the Valencia Ukrainian variety on the 8th day. The studies established a positive effect of foliar feeding of peanut plants with the studied preparations Gumifield Forte and Stim Pure AA Liquid with seaweed extract on the formation of the main elements of peanut variety productivity. In the Local variety, the stem length when using Gumifield Forte for seed treatment and foliar feeding was 36.3% greater than in the control, and in the Valencia Ukrainian and Spanish varieties, the increase was 7.3% and 4.2%, respectively. When Stim Pure AA Liquid was applied during vegetation, the stem length of the Local variety was 25.3% greater than the control, while the increase in the Valencia Ukrainian and Spanish varieties was 1.8% and 12.7%, respectively. The seed yield from beans ranged from 77.3% to 93.9%. The highest seed yield was observed in the Valencia Ukrainian variety when using Gumifield Forte for seed treatment and during vegetation, and amounted to 93.9%. For the Spanish and Local varieties, this indicator was 86.8% and 91.5%, respectively, when using this preparation. When using Stim Pure AA Liquid for foliar feeding, the highest yield was Product Description popup.authors popup.nrat_date 2025-12-26 Close
