1、Optimum Timing of Foliar Nutrient Sprays

Intensively grown crops like cereals are routine sprayed several times during the season for different purposes, like pesticide treatment and growth regulation.

2、Calcium and Potassium Foliar Sprays Affect Fruit Skin Color, Quality Attributes, and Mineral Nutrient Concentrations of ‘Red Delicious’ Apples

This study was conducted to evaluate the influences of foliar spray of potassium (K), calcium (Ca), and their combination on the fruit red skin color and quality attributes of ‘Red Delicious’ apple under conditions of south central Iran with warm and dry summer, where low and high temperature differences are low.

3、The effects of potassium fertilization on water‐use efficiency in crop plants

By using this method, it was possible to demonstrate the extent of several crop (winter wheat, spring triticale, maize, sugar beet) responses to the K supply. Yield increases resulting from K application mostly appeared under conditions of mild water deficit.

ROLE OF POTASSIUM IN FRUIT CROPS

With the changing cropping pattern, need for potassium nutrition has become pertinent to obtain high yield of quality fruits. In this review paper role of potassium on various physiological processes in improving the yield and quality of major fruit crops has been discussed.

In China, the current priority for agricultural policy is high crop yields to meet the food demands of a large and growing population. Long-term sustainable high crop yields require integrated management practices including the application of K fertilizers.

Effectiveness of the rootless fertilization of mineral fertilizers on the productivity of citrus gardens

The purpose of our research is to study the effectiveness of root feeding and leaf feeding of mineral fertilizers, or the effects of rootless feeding on the yield of citrus fruits of young garden and quality of the fruit, as well as the agrochemical composition of the soil.

Interactions of Nitrogen, Phosphorus, and Potassium supplied in Leaf Sprays or in Fertilizer added to the Soil

Potassic fertilizer did not affect leaf area or the estimated volume of spray solution retained on the leaves, but it appeared to reduce uptake of potassium from the spray.

Impact of potassium nutrition on postharvest fruit quality: Melon (Cucumis melo L) case study

Numerous studies have consistently demonstrated that specific K fertilizer forms, in combination with specific application regimes, can improve fruit quality attributes.

The main objective of this conceptual review is to confirm that adequate K management can be used as an important tool to alleviate the negative effects of water deficit on plant growth, yield-component formation, and yield.

Roles of nitrogen, phosphorus, and potassium fertilizers in carbon sequestration in a Chinese agricultural ecosystem

In this study, a meta-analysis was conducted to synthesize 84 long-term trials with 385 paired comparisons to quantify the variance of soil C storage in response to synthetic fertilizer addition.

The young fruit stage of litchi is a critical period for its growth, during which nutrient management significantly impacts fruit quality and yield. Spraying high-potassium fertilizer is a common practice in this phase, but its appropriateness depends on specific conditions.

I. Growth Characteristics of Litchi During the Young Fruit Stage

The young fruit stage of litchi typically occurs from late spring to early summer. During this period, new shoots begin to grow, flower buds differentiate, and fruits gradually form. At this stage, litchi trees have higher nutrient demands, especially for potassium. Potassium fertilization promotes fruit development, increases sugar content, and enhances taste and quality.

II. Functions of Spraying High-Potassium Fertilizer

1. Promotes Flower Bud Differentiation: Moderate potassium application during the young fruit stage can improve flower bud quality, increasing flower quantity and fruit setting rates, which is vital for enhancing yield.

2. Enhances Fruit Quality: High-potassium fertilizers strengthen fruit firmness and sweetness, improving overall quality. They also facilitate starch synthesis, making fruits fuller.

3. Supports Leaf Growth: Proper potassium levels promote leaf expansion and photosynthetic efficiency, providing more nutrients for the tree and supporting fruit development.

III. Precautions for Spraying High-Potassium Fertilizer

1. Appropriate Application Rates: Excessive potassium can cause root burn and harm the root system. It is crucial to apply appropriate amounts to avoid over-fertilization.

2. Timing Is Critical: Apply high-potassium fertilizers during the early to mid stages of the young fruit period when nutrient demands are highest for optimal results.

3. Soil Conditions Matter: Before applying, assess soil fertility. Poor soil may require amendments to improve nutrient availability before fertilization.

4. Balance with Other Nutrients: Coordinate potassium applications with other essential nutrients like nitrogen and phosphorus to ensure comprehensive nutritional support for the tree.

spraying high-potassium fertilizer during the young fruit stage of litchi is beneficial but must be tailored to specific circumstances. Consider factors such as dosage, timing, soil conditions, and balanced nutrition to maximize efficacy. Monitor plant responses and adjust strategies if adverse effects occur. With proper nutrient management, litchi farmers can achieve improved yields and superior fruit quality, leading to better economic returns.
