Nitrogen fertilizer and potassium fertilizer, which one is the best choice for fruit swelling?

Which one between nitrogen and potassium fertilizer promotes fruit swelling faster? What are the roles of nutritional elements during the fruit swelling period? It is understood that nitrogen and potassium fertilizers are sources of nutrient supplementation in plant growth processes, and their proper application can enhance plant growth. So, between nitrogen and potassium fertilizers, which one promotes fruit swelling faster?

Nitrogen and Potassium Fertilizers for Fruit Swelling

Currently, there isn’t a direct comparison between the two because plant growth requires a variety of micronutrients. It’s not solely dependent on a single element for growth.

Comparatively, potassium fertilizer promotes fruit swelling faster than nitrogen fertilizer. During the initial stages of fruit enlargement, nitrogen fertilizer is needed to promote growth and provide nutrients. However, potassium fertilizer is essential after fruit setting. Both types of fertilizers play crucial roles at different stages of plant growth, complementing each other.

Roles of Nutritional Elements During the Fruit Swelling Period

1.For fruits undergoing secondary swelling, they generally have lower sweetness initially and develop sweetness after changing color. Nitrogen is needed during the early stages of fruit enlargement to promote growth and provide amino acids and protein components. Insufficient nitrogen inhibits protein synthesis in fruit cells during enlargement, and cell division is also restricted. Nitrogen is also a fundamental element of plant growth hormones. Excessive nitrogen can lead to excessive fruit growth and decreased sweetness. During the first phase of fruit enlargement, especially before color change, moderate nitrogen application is crucial.

2. Potassium regulates metabolic sources and photosynthetic products within the plant. It’s an essential element for promoting fruit enlargement and color change, facilitating the accumulation of photosynthetic products in fruits and increasing sugar content.
3. Calcium stabilizes cell wall structures, participates in the formation of intercellular substances, enhances adhesion between fruit cells, reduces the likelihood of fruit cracking, and improves fruit surface glossiness. This also reduces the occurrence of diseases like bitter pit and has a significant impact on increasing fruit yield.
4. Boron not only promotes calcium metabolism but also aids in the transfer of organic matter from the wood to the phloem. If boron is deficient, photosynthetic products cannot be transported to fruits or root systems, resulting in a lack of dry matter in the fruits.
5. Magnesium is a primary component of chlorophyll. Adequate magnesium promotes photosynthesis, accelerates the accumulation of organic substances, and thus promotes fruit swelling.

Difference Between Nitrogen and Potassium Fertilizers

• Nitrogen Fertilizer: Main types include ammonium nitrate, ammonium sulfate, urea, calcium nitrate, etc. They provide nitrogen elements to promote vigorous tree growth and increased chlorophyll production.
• Potassium Fertilizer: Main types include potassium chloride, potassium sulfate, potassium dihydrogen phosphate, etc. They provide potassium elements to strengthen stems and branches, promote bud formation, and accelerate fruit ripening.
