INTRODUCTION Cherries are highly sensitive fruit trees that require a balanced supply of nutrients to maintain yield, fruit quality, and tree vigor. Among essential macronutrients, potassium plays a critical role in carbohydrate transport, fruit development, and stress resistance. Potassium deficiency in cherries negatively affects both vegetative growth and fruit quality, leading to significant economic losses. […]

INTRODUCTION Manganese deficiency in cherries is an important micronutrient disorder that negatively affects tree growth, leaf function, and fruit productivity. Manganese plays a vital role in photosynthesis, enzyme activation, and nitrogen metabolism within cherry trees. When manganese availability is limited, essential physiological processes are disrupted, leading to visible deficiency symptoms and reduced yield potential. In […]
