1、Optimal Timing for Applying Boron Fertilizer in Peanut Cultivation

The optimal timing for foliar fertilization in peanuts is during key growth stages, where it rapidly replenishes nutrients, boosts yields, and improves quality.

2、Irrigation and Fertilization Scheduling for Peanut Cultivation under

The aim of this study was to investigate the impact of water and nitrogen regulation on the characteristics of water and fertilizer demands and the yield, quality, and efficiencies of the water and nitrogen utilization of peanuts cultivated under mulched drip irrigation in a desert–oasis region.

3、Irrigation and Fertilization Scheduling for Peanut Cultivation

Peanut cultivation in Xinjiang is in the initial stage of devel-opment; the soil in the area is barren, and there is a large demand for water and nitrogen fertilizer in actual production.

4、Optimum topdressing timing and frequency for peanut yield under drip

In order to establish a high efficiency peanut cultivation technology system for water and fertilizer saving, this paper studied the effect of different topdressing timings and frequencies on peanut growth and yield under underneath film mulched drip fertigation.

Can Foliar Application of Nutrients Increase the Productive

In peanut crops, foliar fertilization can be used during periods of greatest nutritional need, such as during early reproductive growth and production of leaves, flowers, roots and gynophores, penetration of gynophores in the soil and development of pods.

Foliar Fertilization as a Strategy to Increase the Proportion of Mature

To address these questions regarding foliar fertilization effects on peanut maturity, a multi-year and location test was conducted, with the hypothesis that foliar fertilization would amplify pod maturation and increase the proportion of mature pods compared to non-foliar fertilized peanut.

Foliar Mg increases peanut yield by ∼10% under P-limited conditions. Mg boosts photosynthesis via higher stomatal conductance (18%) and photoprotection. A strategy combining foliar Mg with P-efficient cultivars is proposed for sustainable production.

Optimal Timing for Foliar Fertilization of Spring Peanuts

In addition to soil application, foliar fertilization can be beneficial for peanut plants, especially during periods of nutrient deficiency or stress. Foliar fertilizers are sprayed directly onto the leaves, allowing for rapid nutrient absorption by the plant.

Peanut is one of the most important oil crops, and its leaf nutrient status directly impacts growth and yield. proper foliar fertilization is critical for peanut development. Below is a detailed guide on the optimal timing and methods for applying foliar fertilizers to peanuts:

I. Importance of Foliar Fertilization in Peanuts

1. Promotes Nutrient Absorption: Foliar fertilization delivers nutrients directly to young leaves and shoots, increasing nutrient concentration in these tissues and accelerating absorption.
2. Enhances Photosynthetic Efficiency: By boosting leaf nutrient content, foliar fertilization improves photosynthesis, providing sufficient energy and nutrients for peanut growth.
3. Strengthens Stress Resistance: Supplementing microelements and vitamins through foliar applications enhances disease and pest resistance, reducing the incidence of pathogens.

II. Optimal Timing for Foliar Fertilization

1. Early Growth Stage: From seeding to emergence, foliar fertilization quickly addresses soil nutrient deficiencies, promoting root development. Use fast-acting fertilizers like urea or diammonium phosphate to support rapid growth.
2. Flowering Period: During flowering, foliar applications of phosphorus, potassium, boron, and zinc improve pollination and fruit set. These micronutrients enhance pollination rates and pod formation.
3. Pod-Filling Stage: A critical phase, foliar fertilization during pod filling ensures adequate nitrogen, phosphorus, and potassium supply, which affects pod development and quality. Use compound fertilizers containing N, P, K, and microelements to meet diverse nutritional needs.

III. Methods and Techniques for Foliar Fertilization

1. Select Appropriate Fertilizers: Choose formulations based on growth stages and soil conditions. Organic and microelement fertilizers are ideal for early growth and flowering.
2. Dilution: Dissolve or dilute fertilizers thoroughly in water before application to ensure efficient uptake.
3. Even Spraying: Apply uniformly to avoid over-concentration, which can burn leaves. Avoid direct spraying on leaf surfaces to prevent scorching.
4. Weather Considerations: Apply under clear, mild conditions. Avoid extreme heat, drought, or heavy rain, as these reduce effectiveness.
5. Regular Monitoring: Test soil and leaf nutrient levels periodically to adjust fertilization plans.
6. Integrated Management: Combine foliar fertilization with irrigation, drainage, and pest control for holistic crop health.

IV. Cautions and Recommendations

1. Avoid Overapplication: Excessive foliar fertilization can lead to nutrient toxicity. Follow recommended dosages strictly.
2. Quality Control: Use reputable brands. Check labels for nutrient composition and application guidelines.
3. Scientific Application: Tailor fertilizers to growth stages. Prioritize N, P, K in early and flowering stages; focus on N, P, K, and microelements during pod filling.
4. Comprehensive Management: Integrate foliar fertilization with irrigation, pest control, and other practices for optimal yields and quality.

foliar fertilization is a vital technique for improving peanut yield, quality, and stress resistance. Farmers are encouraged to adopt scientific approaches, combine management strategies, and create favorable conditions for healthy peanut cultivation.
