Frontiers

The strategy of foliar Zn spraying was more effective than soil fertilizer N application to biofortify wheat with Zn, especially for foliar Zn supply combined with sucrose.

Foliar Spray VS Soil Application: Which is Better for Your Crops?

Foliar spray is ideal for quick correction of deficiencies, while soil application ensures long-term nutrient availability. A combination of both methods can provide the best results for healthy and productive crops.

Effects of Irrigation and Foliar Nitrogen Application on Yield, Quality

In response to the problem of delayed sowing date affecting the growth of wheat in production, spring irrigation and foliar nitrogen application were used as the main cultivation measures to study the effects on the yield and quality of late sowing wheat.

Effects of irrigation and nitrogen application on NO

Irrigation and nitrogen application can not only increase wheat yield, but also cause nitrogen loss and soil nitrate accumulation.

Optimizing Nitrogen and Phosphorus Fertilizer Application for Wheat

Enhancing crop productivity on alkali soils is essential for food security; however, excessive fertilizer use can lead to soil salinization. Wheat, as a key staple crop, requires an appropriate nitrogen-to-phosphorus fertilization ratio to optimize its yield, yet the ideal ratio remains unclear.

Mode of Application (Foliar, Soil

Nanofertilizers (NFs) are nano-sized chemical substances capable of delivering nutrients to plants for extended periods and with considerably higher efficiency as compared to conventional fertilizers.

Wheat is one of the world's most important food crops, and proper irrigation and fertilization management during its cultivation are critical to improving yield and quality. The question of whether to irrigate the soil first or apply foliar fertilizer initially requires comprehensive consideration of multiple factors. The following analysis explores this issue in detail.

I. Soil Preparation Stage

Before wheat sowing, soil preparation is a crucial step. This includes deep plowing, weed removal, and land leveling. Deep plowing improves soil structure, enhances aeration and water retention, and promotes root growth. Additionally, it distributes soil nutrients more evenly, facilitating nutrient uptake by wheat.

During this stage, it is generally recommended to water the soil first, then apply fertilizers. Watering moisturizes the soil, aiding seed germination and root development. It also reduces soil temperature, minimizing the risk of pests and diseases.

II. Sowing Stage

Sowing marks the start of wheat growth, and correct sowing methods significantly impact yield. Before sowing, soil disinfection is essential to prevent pathogen and pest spread. Controlling sowing density and depth ensures each seed receives adequate nutrients and moisture.

After sowing, light irrigation is typically required to maintain soil moisture. excessive watering should be avoided to prevent waterlogging, which could hinder seed germination and growth. Irrigation decisions should consider weather conditions and soil humidity to avoid overwatering and root hypoxia.

III. Fertilization Stage

Fertilization is vital for wheat growth and yield optimization. Different fertilizer types are needed at various growth stages. Generally, nitrogen fertilizer is applied during the seedling and tillering stages to promote plant growth; phosphate and potassium fertilizers are used during jointing and booting stages to strengthen stems and enrich grains; and compound fertilizers are applied during maturity to meet overall nutritional demands.

For fertilization, it is advisable to water first, then apply fertilizers. Watering ensures soil moisture, aiding fertilizer dissolution and absorption. It also reduces direct soil contact with fertilizers, minimizing potential soil corrosion.

IV. Foliar Fertilizer Application

Foliar fertilization, a modern technique, involves spraying nutrient solutions directly onto leaves. This method is simple, fast-acting, and suitable for various crops.

When applying foliar fertilizers, timing and concentration must align with crop growth stages and soil conditions. Spraying is best done on sunny mornings or late afternoons to avoid leaf scorch from direct sunlight. Concentrations should be adjusted based on crop needs, as excessive levels may damage leaves.

V. Conclusion and Recommendations

wheat cultivation involves soil preparation, sowing, fertilization, and foliar applications. Each step requires tailored practices: prioritize irrigation before fertilization during soil preparation; control sowing density and depth; apply fertilizers after irrigation; and use foliar sprays at optimal times and concentrations.

To ensure healthy wheat growth and high-quality yields, farmers should continuously experiment, adapt, and flexibly apply agricultural techniques. This approach will elevate agricultural productivity and contribute to national food security.
