Abstract
This scientific study aimed to determine the optimal nitrogen concentration within a hydroponic solution for the Rosa variety of cherry tomato plants cultivated in a controlled greenhouse environment. The study was conducted over a period of October 2019 to April 2021. Various treatments were administered, each with distinct nitrogen concentrations, to evaluate their effects on plant growth, yield, and yield-attributing characteristics. The results unequivocally demonstrated that the application of 8 mmol/L of nitrogen (T3) emerged as the most efficacious treatment for optimizing the growth, yield, and yield-attributing characteristics of the cherry tomato plants. These findings hold significant implications for refining nitrogen management practices in horticultural crop production, particularly for the Rosa variety of cherry tomatoes, within controlled greenhouse settings.
