Optimization of potassium fertilization in early and mid-early production of tomato for sustainable yields and economic profitability
Veselina Vasileva
Abstract: Split potassium fertilization is emerging as an effective technique for the prolonged assimilation of significant amounts of accessible potassium during the vegetation, with the aim of establishing a positive potassium balance in the soil and achieving increased yields of quality produce. The aim of this study was to determine the economic efficiency of the partitioning and split application of potassium doses in the cultivation of tomatoes, both in the early and mid-early production. The results showed that tomato plants demonstrate improved potassium utilization through split application, resulting in increased yields and total production revenues. Split fertilization alternatives proved to be economically viable, with N24Р12К8+8+8 approach being particularly beneficial in early tomato production. This study underlines the importance of optimizing fertilization practices in agriculture, highlighting the potential to increase economic efficiency and profitability for farmers and to ensure the sustainable use of soil resources.
