1、Foliar feeding of corn / maize – the way to achieve better crops

Haifa Bonus 13-2-44 with the special sticking agent, sprayed in 2-3 weeks interval during this stage, will enhance growth, plant development, and future grain and corncob formation.

2、Corn is Tasseling! Points to Ponder to Determine Fungicide Applications

There are numerous options to select from to manage foliar diseases. In 2014, Dr. Collins and I conducted a test of 5 different fungicides on corn and applied the product at the V6 and Tassel stage, as well as two applications, one at V5 and followed by a R2 stage of various fungicides.

3、Effect of Foliar Nutrition on Yield and Economics of Sweet Corn

In general, foliar spray of vermiwash would be recommended as a better technique of supplying nutrients to plants at a more rapid rate than methods involving soil application. Hence, there is a need to evaluate the effective best foliar nutrition treatment to realize higher productivity of sweet corn.

4、The Complete Guide to Fertilizing Corn for Optimal Growth and High

Granular Fertilizers: These are slow-release fertilizers that provide a steady supply of nutrients over time. They are easy to apply and are commonly used for corn. Liquid Fertilizers: Liquid fertilizers can be applied as a foliar spray or directly to the soil.

Boron applications for increased yields of high

• Corn requires an adequate supply of available boron, especially during tasseling and silking. Where needed, a preplant application of Granubor®or a foliar spray of Solubor®prior to these stages of growth generally will ensure an adequate supply of boron.

Experts discuss the potential benefits and methods of applying nitrogen to corn at tasseling stage, offering insights on timing, amount and application techniques.

Foliar nutrition: Potential and challenges under multifaceted

The potential of foliar fertilization in improving crop yield and quality under environmental stresses has been evaluated based on a meta-analysis. Foliar-applied fertilizers showed higher crop plants yield and quality traits by 15–19% and 9–29%, respectively, under different environmental stresses.

Optimum Timing of Foliar Nutrient Sprays

For an optimum yield response to foliar fertilization it is possible that the optimum growth stage of the plant for the timing of foliar nutrient sprays does not necessarily fall within the recommended time interval as dictated by pesticide spraying.

The tasseling stage of corn is a critical period for its growth and development. During this phase, the nutrient absorption and assimilation of corn leaves significantly impact yield and quality. Foliar fertilization is an efficient method for nutrient supplementation, enabling rapid delivery of nutrients to various parts of the plant and promoting healthy growth. Below are recommendations for foliar fertilizers suitable for application during the tasseling stage of corn:

1. High-Nitrogen Fertilizers

• Mechanism: Nitrogen is essential for protein synthesis and critical for corn growth. Nitrogen fertilizers strengthen stems, promote lush foliage, and enhance photosynthetic efficiency.
• Recommendation: Use urea, ammonium nitrate, or other high-nitrogen formulas. Avoid overapplication, as excess nitrogen may cause excessive vegetative growth, reducing kernel weight and grain filling.

2. Compound Fertilizers

• Mechanism: Compound fertilizers contain multiple nutrients (e.g., phosphorus, potassium, microelements), addressing diverse needs during different growth stages.
• Recommendation: Select formulations with balanced phosphorus and potassium to support root development and stress resistance. Adjust micronutrient ratios based on soil tests to ensure comprehensive nutrition.

3. Bio-Fertilizers

• Mechanism: Bio-fertilizers enriched with beneficial microorganisms improve soil structure, enhance fertility, and convert organic matter into plant-available nutrients.
• Recommendation: Choose reputable brands and verify product labels for active microbial ingredients (e.g., Azospirillum, Bacillus species).

4. Water-Soluble Fertilizers

• Mechanism: These fertilizers dissolve quickly in water, allowing rapid absorption—ideal for dry regions or water-scarce conditions.
• Recommendation: Use fast-dissolving formulas with moderate nutrient concentrations. Avoid products containing heavy metals or harmful chemicals.

5. Micronutrient Fertilizers

• Mechanism: Micronutrient fertilizers address deficiencies in elements like zinc, iron, or manganese, which are vital during specific growth stages.
• Recommendation: Apply based on soil test results to target deficiencies (e.g., zinc for pollination, iron for chlorosis prevention).

6. Key Considerations

• Timing: Apply during the tasseling stage (from jointing to tasselling) in early morning or evening to minimize leaf damage from sunlight.
• Concentration: Follow dilution ratios on product labels; excessive concentrations may burn leaves.
• Application Method: Spray uniformly using a fog nozzle, avoiding direct contact with ears to prevent contamination.
• Rotation: Avoid prolonged use of a single fertilizer. Combine with soil amendments and other agronomic practices.
• Soil Conditions: Soil pH, organic matter, and nutrient levels affect efficacy. Conduct soil tests before application.
• Monitoring: Observe crop response post-application and adjust strategies if abnormalities occur.

strategic use of foliar fertilizers during the tasseling stage can optimize corn health, yield, and quality.
