1、Foliar fertilization of high

In the first year, there was a tendency toward increased yields of pods (up to 13%) and of hay (up to 16%) when four foliar fertilizer applications (10 kg N, 1 kg P, 3 kg K and 0.5 kg S/ha/application) were given, at one-week intervals.

Soil applications of fertilizers are mainly done on the basis of soil tests, whereas foliar nutrient applications are mainly done on the basis of visual foliar symptoms or plant tissue tests. Hence, correct diagnosis of nutrient deficiency is fundamental for successful foliar fertilization.

In hydroponics experiments, foliar applications of FeSO4, Fe-EDTA, sequestrene and ferric chloride were applied to check their effect on Fe deficiency chlorosis in two varieties of peanut already screened as BARI-2000 (Fe deficiency tolerant) and BARD-699 (Fe deficiency sensitive).

The micronutrients are essential to physiological functions in plant metabolism, and leaf uptake has been extensively studied as a biological process, however, the mediating factors are still unsolved.

Foliar Fertilization for Sustainable Crop Production

Here I review the extensive work that has been carried out on the effectiveness of foliar-applied nutrients, the mechanisms of foliar absorption, and transport.

Iron fertilizers applied to calcareous soil on the growth of peanut in a pot experiment

A greenhouse pot experiment was conducted with peanuts (Arachis hypogaea L., Fabceae) to evaluate iron compound fertilizers for improving within-plant iron content and correcting chlorosis caused by iron deficiency.

Foliar Fertilization

Foliar fertilization has an increasing role in crop nutrition, but years of research and development work are still needed. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.

Application of Manures and Fertilizers

The benefits of liquid fertilizer injection include increased fertilizer use efficiency throughout the crop cycle, protection of the environment (by preventing volatilization of ammonia and leaching of nitrates), prevention of fertilizer injury to plants, and an economical practice for the farmers.

COMPARISON OF DIFFERENT FOLIAR

Foliar fertilization is a rapid, efficient way to improve crop nutrient status during periods of high nutrient demand or when soil conditions (low tempera-ture, salinity, pH) render soil nutrients and soil-applied fertilizers less available to the plant’s roots.

Peanuts are one of the world’s most important oil crops, valued for their high yields of oil and protein. their long growth cycle and sensitivity to environmental conditions necessitate careful management to ensure healthy development and optimal productivity. Foliar fertilization is a critical supplementary practice in peanut cultivation, enhancing growth rates and yield. Below is a detailed explanation of why foliar fertilizers are essential for peanuts, along with application methods and precautions:

I. The Importance of Foliar Fertilization for Peanuts

1. Promotes Growth Foliar fertilizers, applied directly onto the leaf surface, are rapidly absorbed and utilized by the plant. This method effectively addresses nutrient deficiencies or imbalances in the soil. For example, microelements like iron (Fe) and manganese (Mn), which are crucial for peanut growth but poorly soluble in soil, can be quickly absorbed through foliar spraying, accelerating development.

2. Increases Yield Foliar fertilization improves peanut quality, increasing pod count per plant and pod weight, thereby boosting total yield. Phosphate and potassium foliar sprays, for instance, enhance disease resistance and drought tolerance, resulting in sturdier plants and higher productivity.

3. Cost-Effective Compared to traditional soil fertilization, foliar spraying saves time, labor, and costs. Farmers can apply fertilizers efficiently without disrupting other agricultural tasks.

II. Types and Selection of Peanut Foliar Fertilizers

1. Nitrogen (N) Fertilizers Nitrogen promotes stem and leaf growth and photosynthesis. excessive nitrogen can cause excessive vegetative growth, hindering fruit development. Apply in "small, frequent doses" to avoid over-fertilization.

2. Phosphate (P) Fertilizers Phosphorus strengthens roots, improves drought resistance, and supports flower bud differentiation. Adjust P application based on soil tests and crop needs.

3. Potassium (K) Fertilizers Potassium enhances disease resistance, root development, and lodging resistance. Ensure adequate K intake to meet peanut requirements.

4. Microelements

   • Boron (B): Critical for flower and pollen tube development.
   • Zinc (Zn): Strengthens disease resistance. Supplement B, Zn, and other microelements as needed.

5. Water-Soluble Fertilizers These efficient, eco-friendly formulations dissolve quickly and are ideal for nutrient-deficient or water-intensive crops. They offer high efficacy, low environmental impact, and cost savings.

6. Organic Fertilizers Animal manure, compost, and other organic matter improve soil structure, water retention, and microbial activity. Use cautiously to avoid overapplication, which may lead to soil acidification or pest issues.

III. Application Methods for Peanut Foliar Fertilizers

1. Dilution Ratio Mix 10 milliliters of foliar fertilizer per liter of water. Adjust concentrations carefully to avoid overdosing.

2. Timing Apply in early morning or late afternoon when temperatures are cool, reducing evaporation and sun damage. Avoid windy or rainy conditions.

3. Uniform Coverage Use sprayers or brushes to ensure even distribution across leaves. Avoid damaging foliage during application.

IV. Precautions for Foliar Fertilization

1. Avoid Overapplication Stick to "small, frequent doses" to prevent nutrient excess, which can harm peanut growth.

2. Weather Conditions Apply on calm, sunny days. Wind or rain reduces absorption and effectiveness.

3. Avoid Mixing with Pesticides Do not combine foliar fertilizers with pesticides, as chemical reactions may reduce efficacy. If multiple treatments are needed, follow separate application guidelines.

4. Monitor Plant Response Observe plants after application. Discontinue use if leaves yellow, wilt, or show abnormalities, and consult experts.

foliar fertilization boosts peanut growth, yield, and cost-efficiency. To maximize benefits, select appropriate fertilizers, follow correct application methods, and adhere to precautions. Proper use of foliar fertilizers ensures healthy peanut crops and high-quality yields.
