The-most important work in loquat production is to maintain the balance between vegetative and reproductive growth of plants, Nitrogen played significant roles in vegetative growth especially for shoot and leave growth. Phosphorous raised fruit acidity and potash could increase fruit size. For better understanding the most appropriate sampling stage and the optimun range of the nutrients, it is necessary to sample leave and shoot monthly for diagnosis and fertilizer recommandation. It is also important to find the relationships between plant nutrients, carbohydrate content on the fruit yield and quality.
