1、Application of the full nitrogen dose at decreasing rates by foliar

These findings demonstrate that foliar fertilization can maintain wheat productivity while reducing nitrogen input by up to 40 %, enhancing NUE and grain quality. This strategy also provides fertilizer savings and environmental benefits, with potential applications in drought-prone areas.

2、Optimal Timing for Foliar Fertilization in Wheat

The appropriate timing for applying foliar fertilizer to wheat varies depending on regional climate, local conditions, and wheat varieties. the most suitable period generally falls between the jointing and heading stages.

3、The Timing of Application and Inclusion of a Surfactant Are Important

The aims of this study were to investigate the influence of adjuvant choice and application timing of foliar applied phosphoric acid on leaf wettability, foliar uptake, translocation, and grain yield of wheat plants.

4、Enhancing Wheat Yield and Quality Through Late

Late-season foliar nitrogen (N) application is widely employed to improve wheat grain yield and protein concentration, particularly during later growth stages when root activity declines and N uptake becomes less efficient.

5、Timing of nitrogen fertilization and shading affect the transition of

To characterize the biochemical processes of the transition, we here analyzed the interactions among greenness, soluble protein, amino acid and protease activity in the flag and second leaves of ripening wheat plants.

The Timing of Application and Inclusion of a Surfactant Are Important

Past studies have suggested the optimal timing of foliar P application is from canopy closure to anthesis (reviewed in Noack et al., 2011). The adhesion of foliar fertilizers is particularly important for wheat leaves compared to some other broadacre crops.

Foliar Nitrogen Application Timing Influence on Grain Yield

The objectives were (i) determine the optimal timing of foliar N for increased grain protein of hard red winter wheat (HRWW) and spring wheat (HRSW), (ii) evaluate effect of foliar N on grain yield, and (iii) determine relationship of grain protein to foliar N application and grain yield.

TITLE OF THE PAPER

Among application timings, foliar application of sulphur at two equal splits (50% each at tillering and booting) was a better time for improving growth, yield and yield components of wheat.

Effect of Foliar Fertilization on the Physiological Parameters

Foliar fertilizers play a crucial role in calibrating and forming active growth intervals correlated with productivity factors. The research was conducted over a two-year period using the Andrada winter wheat variety.

Optimal nitrogen management to achieve high wheat grain yield, grain

Furthermore, adopting common N fertilization practices alongside irrigation and implementing pre-anthesis N addition in medium soil texture and humid climate conditions also contributed to achieving optimal wheat performance.

Foliar fertilization is a common practice in modern agriculture, whereby nutrients are directly applied to plant leaves to promote growth and enhance yields. Selecting the appropriate timing for this process can significantly improve fertilizer efficiency. Below is a detailed guide on the optimal periods and methods for applying foliar fertilizer to wheat:

I. Optimal Timing for Foliar Fertilization in Wheat

1. Jointing Stage The jointing stage is a critical period for wheat development, characterized by high nutrient demand. Applying foliar fertilizer during this phase supplements essential nutrients, strengthens stems, and enhances stress resistance. The best time for application is at the early jointing stage (after the emergence of the first compound leaf).

2. Heading Stage During heading, when wheat begins to form grain, foliar fertilization boosts photosynthesis, increases dry matter accumulation, and improves grain yield. Apply the fertilizer when wheat enters the heading phase to support growth and development.

3. Maturing Stage In the final week before harvest, foliar fertilization promotes grain filling and improves quality. Applying fertilizer at this stage ensures optimal maturation and readiness for harvest.

II. Application Methods and Precautions

1. Application Methods

   • Dilution Ratio: Mix fertilizer with water according to specified concentrations (e.g., 10 mL of fertilizer per liter of water).
   • Timing: Apply on calm or mild wind days to avoid drift. Ideal times are early morning or evening when temperatures are cooler, facilitating absorption.
   • Target Areas: Spray evenly on both sides of leaves using a nozzle. Avoid focusing solely on stems to prevent disease risk.
   • Dosage: Apply 20–50 kg of diluted fertilizer per mu (~0.067 hectares). Excessive use may lead to waste or soil salinization.

2. Precautions

   • Fertilizer Type: Choose formulations suited to wheat needs, such as diammonium phosphate or urea.
   • Environmental Conditions: Ensure suitable temperature and humidity. Avoid extreme weather during application.
   • Soil Fertility: Adjust dosage based on soil conditions. Increase fertilizer in low-fertility soils.
   • Pest Management: Monitor for diseases or pests and address issues promptly during application.

III. Benefits of Foliar Fertilization in Wheat

1. Yield and Income Growth: Foliar fertilization increases wheat yield and quality, directly boosting farmer income.
2. Quality Improvement: Enhances photosynthesis, nutrient balance, and marketability of grain.
3. Resource Conservation: Reduces synthetic fertilizer and pesticide use, lowering costs and environmental impact.
4. Stress Resistance: Strengthens defense against pests, diseases, and adverse weather, supporting food security and sustainable agriculture.

The optimal periods for foliar fertilization in wheat are the jointing, heading, and maturing stages. Effective application requires attention to fertilizer type, dilution, timing, and environmental factors. By following scientific guidelines, farmers can maximize yield, improve grain quality, and achieve economic and ecological benefits.
