The fertilization with potassium and zinc rates influences the growth and development of ‘Taquara’ bamboo plants (B. tuldoides), promoting increases in most of the analyzed variables.

3、Agronomic Biofortification Increases Concentrations of Zinc and Storage

Zinc (Zn) is crucial for both plant metabolism and human nutrition, with its deficiency being a global health concern. Strategies to increase its availability in food, such as agronomic biofortification, have gained prominence.

Fertilization Techniques for Cowpea (Vigna radiata) During Flowering Stage

Proper fertilization during its growth cycle is critical to ensuring healthy development and boosting yields. Below are specific guidelines for fertilizing cowpea during the flowering stage:

Effect of Zinc Fertilization on Nutritional Quality of Cowpea Cultivars

Cowpea varieties responded differently in uptake of zinc under different level of zinc (Mfeka, 2017). Proximate composition differs among genotypes in term of protein, dietary fibre contents and various other quality parameters (Carvalho et al., 2012).

ABSTRACT Zinc (Zn) is an essential micronutrient for plants, due to its role as a functional, structural, or regulatory cofactor in a large number of enzymes. The element is necessary for the synthesis of tryptophan, which is a precursor of indoleacetic acid.

Effect of sulphur and zinc fertilization on growth and yield of cowpea

A field experiment was conducted at Research Farm of Suresh Gyan Vihar University, Jaipur (Rajasthan) during kharif 2023 on loamy sand soil, which consisted ten treatments viz. control (T 0), Sulphur @ 15 kg ha -1 (T 1), Sulphur @ 30 kg ha -1 (T 2), Sulphur @ 15 kg ha -1 (T 3), Sulphur @ 45 kg ha -1 (T 4), Sulphur @ 15 kg ha -1 + Zn @ 0.1% (T 5)...

Zinc deficiency decreases plant growing by increasing the concentration of boron in the young leaves and tips of the branches, which helps to prevent of transfer of Fe from root to shoot in zinc deficiency conditions.

Cowpeas, also known as Vigna radiata or asparagus beans, are a popular vegetable prized for their crisp texture and nutritional value. Zinc, an essential micronutrient for plant growth, plays a critical role in development and stress resistance. Proper zinc fertilization can significantly enhance both the quality and yield of cowpeas. Below is a detailed guide on the best timing, methods, and precautions for applying zinc fertilizer.

1. Optimal Zinc Application Period

1. Early Growth Stage

From seedling to early flowering, cowpeas are highly sensitive to zinc deficiency. Applying zinc fertilizer during this phase promotes root development, strengthens pest/disease resistance, and ensures healthy growth and future productivity.

2. Post-Flowering to Pod-Setting Stage

This period is critical for pod formation and seed development. Zinc application here supports efficient pod setting and improves grain quality.

3. One Month Before Harvest

Applying zinc fertilizer during this stage increases protein content, enhances nutritional value, and prolongs post-harvest storage life.

2. Fertilization Methods

1. Soil Treatment

• Dissolve zinc sulfate in water and evenly spray it over the planting area.
• Plow the soil to ensure thorough absorption by roots.
• Note: Avoid overapplication to prevent soil contamination.

2. Foliar Spraying

• Dilute zinc sulfate to the recommended concentration.
• Apply the solution directly onto cowpea leaves using a sprayer.
• Note: Monitor concentration and frequency to avoid foliage damage.

3. Root-Targeted Topdressing

• Mix zinc sulfate with water and pour it near the root zone.
• Suitable for large-scale farms but requires precise dosage control to prevent waste or soil salinization.

3. Key Precautions

1. Select the Right Zinc Product

Choose appropriate zinc formulations (e.g., zinc sulfate, zinc oxide) based on growth stages and soil conditions.

2. Control Dosage

Excessive zinc raises soil ion concentrations, harming plants. Adjust amounts according to soil fertility and crop needs.

3. Avoid Mixing with Other Fertilizers

Zinc may react with nitrogen, phosphorus, or potassium fertilizers, reducing effectiveness. Apply zinc separately.

4. Environmental Protection

• Prevent runoff into water sources to avoid pollution.
• Follow local regulations for safe agricultural practices.

Strategic zinc fertilization boosts cowpea quality and yield. By timing applications to key growth stages, using proper methods, and adhering to environmental guidelines, farmers can maximize results while minimizing risks.
