Abstract
Guava (Psidium guajava L.) is an economically significant fruit crop with diverse applications in the food industry. The foliar application of Zinc Sulphate and Brassinosteroids has a significant impact on the overall growth of guava plants, as it greatly affect the plant productive efficiency by changing various parameters of horticultural features such as fruiting potential, and quality of fruit. Major role of zinc sulphate is proper nitrogen metabolism, helps in cell division, and hormonal regulation for maintain proper quality of fruit with increased number of fruit set and reduced fruit drop. Brassinosteroids play a vital role in making plant tolerant against biotic and abiotic stresses. Furthermore, the combined treatment exhibited a positive influence on fruit yield, with an observable increase in the number and size of harvested fruits. Quality parameters, including fruit size, weight, and nutritional content, were also assessed. The foliar spray with Zinc Sulphate and Brassinosteroids contributed to improved fruit quality, as evidenced by enhanced sugar content, vitamin levels, and overall taste.
