Effect of liquid fertilizers and growth stages of application on growth

Foliar application of liquid fertilizer 1% 13:0:45 + PDKV Grade-2 (L4) recorded significantly higher grain yield ha-1 (3830 kg) and straw yield ha-1 (5002 kg) of paddy over rest of the liquid fertilizers.

Nutrient Management :: Methods of Fertilizers Application

It is the placement of ammoniacal nitrogenous fertilizers in the reduction zone of soil particularly in paddy fields, where ammoniacal nitrogen remains available to the crop. This method ensures better distribution of fertilizer in the root zone soil and prevents loss of nutrients by run-off.

Paddy Crop Cultivation, Best Fertilizer for Paddy Cultivation

There are various scientific data to show that the application of Nitrogen, phosphorus & potassium fertilizers can produce higher yields in comparison to either applying only nitrogen or Nitrogen & phosphorus.

II. Organic Fertilizers: These substances made up of one or more unprocessed material (s) of a biological nature (plant animal) and may include unprocessed mineral material that have been altered through microbiological decomposition process.

The cultivation of vegetables in paddy fields is a critical component of agriculture, providing not only abundant nutrition but also substantial income for farmers. To ensure healthy growth and high yields of paddy field vegetables, selecting appropriate foliar fertilizers is essential. Below is a detailed introduction to the types and application methods of foliar fertilizers suitable for paddy field vegetable cultivation, aiming to offer practical fertilization advice for farmers.

I. Types and Selection of Foliar Fertilizers

1. Nitrogen-Based Foliar Fertilizers

• Urea: A commonly used nitrogenous foliar fertilizer, urea rapidly replenishes nitrogen, promoting leaf growth and differentiation. excessive use can disrupt protein synthesis in plants, hindering normal development. Control dosage to avoid overapplication.
• Potassium Nitrate: A compound nitrogen fertilizer containing nitrogen, phosphorus, and potassium. It supports comprehensive plant growth but requires careful dosing to prevent nutrient imbalance or damage.

2. Phosphorus-Based Foliar Fertilizers

• Potassium Dihydrogen Phosphate (PDP): An efficient phosphorus fertilizer that enhances root development, strengthens stems, improves photosynthesis, and boosts disease resistance.
• Superphosphate: A traditional phosphorus source suitable for various crops and soils. Adjust usage based on soil conditions and crop needs.

3. Potassium-Based Foliar Fertilizers

• Potassium Sulfate: A fast-acting potassium fertilizer that promotes root and stem health, enhances disease resistance, and improves overall plant vigor.
• Potassium Chloride: A stable potassium source for diverse crops and soils. Adjust according to soil type and crop requirements.

4. Micronutrient-Based Foliar Fertilizers

• Borax: Crucial for boron supplementation, it strengthens roots, stems, and improves disease resistance, flower bud differentiation, and fruit development.
• Zinc Sulfate: A versatile micronutrient source that enhances growth and yield. Dosage should align with soil and crop demands.

5. Organic Foliar Fertilizers

• Composted Chicken Manure: Rich in organic matter and nutrients, it improves soil structure, boosts microbial activity, and provides balanced nutrition. Avoid overapplication to prevent damage.
• Green Manure: A natural nutrient source (nitrogen, phosphorus, potassium) that improves soil texture and aeration. Adjust based on soil and crop needs.

II. Application Methods of Foliar Fertilizers

1. Dilution Ratios

• Urea: 0.2%–0.3% (2–3g urea per 100mL water). Adjust based on crop requirements.
• Potassium Nitrate: 0.3%–0.5% (3–5g per 100mL water). Modify ratios for optimal results.

2. Spray Timing

• Urea/Potassium Nitrate: Apply in early morning or evening to avoid high temperatures. Limit spray duration to <2 hours to prevent damage.

3. Spray Techniques

• Use sprayers or manual tools to evenly cover leaves. Ensure full leaf coverage for maximum absorption.

4. Precautions

• Maintain proper distance to avoid direct contact with tender leaves or flowers.
• Reduce watering after application to prevent nutrient runoff. Monitor plants for abnormal reactions.

III. Application Tips for Foliar Fertilizers

1. Fertilizer Selection

• Choose based on crop needs and soil conditions (e.g., nitrogen, phosphorus, potassium, micronutrients, or organics). Prioritize water-soluble and stable formulations.

2. Dilution and Mixing

• Follow recommended concentrations to avoid damage. Observe crop responses (leaf color, growth) to adjust dosages. Avoid incompatible mixtures of different fertilizers.

3. Timing and Frequency

• Apply during critical growth stages (e.g., rapid growth phases) for best results. Avoid excessive frequency to prevent nutrient imbalance.

4. Storage and Transport

• Store in cool, dry, ventilated areas away from sunlight. Transport in dedicated containers to prevent contamination. Discard变质 or compromised products.

IV. Practical Examples

1. Rice

• Case: Combining nitrogen, phosphorus, potassium, and micronutrient foliar fertilizers (e.g., urea, PDP, potassium chloride, borax, zinc sulfate) enhanced tillering, stem strength, disease resistance, and grain quality.
• Result: Faster growth, increased tillers, sturdier stems, and higher yields.

2. Corn

• Case: Nitrogen, phosphorus, potassium, and micronutrient foliar fertilizers (e.g., urea, PDP, potassium sulfate, borax) promoted leaf expansion, root development, and kernel quality.
• Result: Taller plants, larger ears, and improved grain plumpness.

3. Vegetables

• Case: Balanced use of nitrogen, phosphorus, potassium, and micronutrient foliar fertilizers (e.g., composted chicken manure, green manure) supported healthy growth and reduced diseases.
• Result: Enhanced leaf size, stem thickness, and marketable yield.
