Potassium spraying during the growth stage of melons can significantly boost the levels of β-carotene, a vital nutrient that serves as a precursor to vitamin A. Known for its strong antioxidant properties, β-carotene plays a crucial role in supporting immune function, eye health, and overall well-being in humans. Applying potassium externally, through foliar sprays, not only enhances the nutritional value of the fruit but also stimulates photosynthesis, increases sugar content, and improves vitamin C levels in melons. As a result, it is common practice to spray potassium once a week during the later stages of growth, sometimes up to three to five times, which leads to sweeter, higher-quality melons that are more appealing to consumers.
Potash available on the market is safe, cost-effective, and can be easily combined with pesticides without causing harm. Additionally, when calcium is applied alongside potassium fertilizer, it helps extend the shelf life of the melons and strengthens their resistance to diseases. This combination not only improves the fruit's storage potential but also contributes to better overall plant health. By using these fertilizers strategically, farmers can enhance both the yield and quality of their crops, making it a valuable practice in modern agricultural production.
