1、Foliar selenate application enhance physiological, organic compounds

Herein, in this study, we selected sweet potato as the plant to test, and the foliar application of liquid organic Se fertilizer as exogenous Se addition.

2、What Foliar Fertilizers Are Effective for Sweet Potatoes in the Later

The choice of effective foliar fertilizers in the later stages depends on factors such as the growth phase, soil conditions, climate, and varietal characteristics of sweet potatoes.

3、Enhancing yield and nutritional quality of sweet potato through

Our study demonstrates that exogenous Se application, particularly through foliar or combined soil and foliar methods, significantly enhance Se content, yield, and nutritional quality in sweet potato tubers.

4、Effects of Bio and water

To verify an effective approach for alleviating problems associated with the consecutive monoculture of sweet potato, five fertilizer treatments were designed under plastic film-mulched,...

5、Glycine

Whether chelated Zn fertilizers can improve Zn concentration in edible roots of sweet potato while concomitantly avoiding apparent adverse effects deserves detailed study.

Growing Sweet Potatoes

Recommendation: applying a biostimulant or enhanced nutrient fertilizer like BIOZ, X-tra with Agrolution pHlow or Polysulphate as an early season program can improve nutrient uptake.

Foliar Fertilizer Applications on Sweet Potato

All foliar fertilizer treatments resulted in higher sweet potato yield than the no foliar check. Ferti-Rain and ferti-Rain + Pro-Germinator provided the best yields, indicating that the crop needed both phosphorus and potassium, as well as some nitrogen and sulfur.

12 Best Fertilizer For Sweet Potato [Organic & Inorganic]

In this article, we have compiled a list of the 12 best fertilizers for sweet potatoes that can help you achieve optimal growth and yield.

Effects of foliar Fe and Zn fertilizers on storage root Fe, Zn, and

Foliar sprays of iron (Fe) and zinc (Zn) fertilizers are effective in improving Fe and Zn concentrations in sweet potato.

Foliar selenate application enhance physiological, organic compounds

Se, and application of 10 mg L−1 Se significantly increased photosynthesis (Pn) while slightly decreasing leaf chlorophyll content. The contents of polysaccharides and proteins increased with certain Se application.

The seedling stage of sweet potatoes is a critical period for growth, during which the plants have high nutritional demands. Foliar fertilization is an efficient method of applying nutrients directly to plant leaves, enhancing nutrient uptake efficiency. Applying suitable foliar fertilizers during this stage can promote plant growth and development, while improving yield and quality.

1. Selection of Foliar Fertilizers

When choosing foliar fertilizers, consider the following factors:

(1) Nutrient Composition

Sweet potato seedlings primarily require macroelements such as nitrogen (N), phosphorus (P), and potassium (K). Select formulations and concentrations based on the growth stage of the plants and soil conditions.

(2) Solubility

Foliar fertilizers must be highly soluble to ensure easy application and absorption. Some products contain organic acids or surfactants to improve solubility.

(3) Stability

The fertilizer should remain stable under environmental conditions to avoid degradation. Certain formulations include preservatives or antioxidants to enhance stability.

(4) Safety

Prioritize fertilizers that are safe for humans and the environment, avoiding phytotoxicity or pollution. Products containing natural ingredients, such as seaweed extracts or bio-enzymes, often offer better safety profiles.

2. Application of Foliar Fertilizers

(1) Dilution Ratio

Mix the foliar fertilizer with water according to the recommended concentration. Typically, a dilution ratio of 1:1000 (fertilizer:water) is standard.

(2) Timing

Apply foliar fertilizers in the morning or evening to avoid direct sunlight. Timing should align with the crop’s growth stage and weather conditions.

(3) Method

Use a sprayer to evenly apply the solution, maintaining an appropriate distance from the plants. Ensure thorough coverage without overapplication or uneven distribution.

(4) Dosage

Adjust the dosage based on the crop’s growth stage and soil conditions. For sweet potato seedlings, a typical application rate is 2–5 liters per mu (0.066 hectares).

3. Effects of Foliar Fertilizers

(1) Promotes Growth

Nutrients in foliar fertilizers are rapidly absorbed, accelerating plant growth and development.

(2) Increases Yield

By enhancing photosynthetic efficiency and accumulating more photosynthates, foliar fertilizers boost overall yield.

(3) Improves Quality

These fertilizers elevate starch content and quality while reducing sugar levels, enhancing market value.

(4) Strengthens Disease Resistance

Certain ingredients in foliar fertilizers possess antibacterial or antiviral properties, strengthening the plant’s immune response.

Foliar fertilization during the sweet potato seedling stage is an effective strategy to optimize growth, yield, and quality. When selecting and applying foliar fertilizers, prioritize nutrient composition, solubility, stability, and safety to ensure optimal results.
