1、Rice Fertilizer & Crop Guide

Haifa’s rice fertilizer programs emphasize strategic, crop-specific fertilization—particularly nitrogen, potassium, zinc, and silicon—combined with foliar applications at critical growth stages.

2、Precise delivery of nitrogen at tillering stage enhances grain yield

To assess the effects of precise application of nitrogen fertilizer at tillering stage as ‘tillering-fertilizer’ on grain yield and nitrogen use efficiency, field trials were conducted in the late season of 2019 and 2020, in addition to a radioisotope 15N tracer experiment.

3、Synergistic Effects of Combined Foliar Fertilizers on Growth, Stress

Studies have shown that nitrogen (N) and potassium (K) are key nutrients for rice growth. By providing sufficient nitrogen and potassium, nutrient-enhanced foliar fertilizers can significantly improve rice tiller numbers and leaf photosynthetic efficiency (Mahmoodi et al., 2020).

4、Synergistic Effects of Nitrogen and Zinc Foliar Application on Yield

This study addresses this knowledge gap by examining the physiological and molecular responses of rice to foliar application of nitrogen (N) and zinc (Zn) individually and in combination at different growth stages.

5、Which Foliar Fertilizers Promote Rapid Growth and High Yields in Rice?

Studies have shown that nitrogen (N) and potassium (K) are key nutrients for rice growth. By providing sufficient nitrogen and potassium, nutrient-enhanced foliar fertilizers can significantly improve rice tiller numbers and leaf photosynthetic efficiency (Mahmoodi et al., 2020).

Synergistic Effects of Nitrogen and Zinc Foliar Application on Yield

Foliar application of N+Zn+ at the tillering stage resulted in a 62.01% increase in grain yield compared to the control. Additionally, Zn concentrations in brown rice were increased by 26.04% and 34.20% when N0Zn+ and N+Zn+ treatments, respectively, were applied at panicle initiation.

Recent advances demonstrate significant improvements in growth, yield, and physiological responses through foliar application of conventional fertilizers, nano-formulations, and organic liquid manures.

Which Foliar Fertilizer is More Effective for Rice?

In rice cultivation in Northeast China, foliar fertilization is one of the effective measures to improve crop yield and quality. Selecting the appropriate foliar fertilizer is crucial for promoting healthy rice growth, enhancing stress resistance, and increasing productivity.

Foliar fertilization during rice tillering is a critical practice for improving yield and grain quality. Selecting appropriate foliar fertilizers is essential to promote healthy growth, enhance stress resistance, increase productivity, and improve crop quality. Below is an analysis of recommended foliar fertilizers and their application effects:

1. Potassium Dihydrogen Phosphate (KH₂PO₄)

• Mechanism: A common plant nutrient regulator providing phosphorus (P) and potassium (K). It promotes root development and strengthens disease resistance.
• Application: Spray during tillering or booting stages to support tiller formation and panicle development.
• Effectiveness: Enhances tillering, increases tiller count, and boosts per-plant productivity. Potassium supplementation improves stress tolerance and disease resistance.

2. Borax (B₄O₃·10H₂O)

• Mechanism: A micronutrient fertilizer critical for rice development. Boron promotes pollen tube elongation and improves seed setting.
• Application: Spray from heading to maturity stages to ensure grain fill.
• Effectiveness: Significantly reduces empty grains, increases seed setting rate, and enhances grain plumpness, thereby improving economic value.

3. Ammonium Molybdate (NH₄MoO₄)

• Mechanism: Molybdenum (Mo) is essential for photosynthesis and respiration. It optimizes nutrient metabolism in rice.
• Application: Spray during tillering or booting stages to support panicle and tiller development.
• Effectiveness: Boosts photosynthetic efficiency, strengthens stress resistance, and promotes root development, enhancing nutrient uptake capacity.

4. Zinc Sulfate (ZnSO₄)

• Mechanism: Zinc (Zn) is vital for rice growth. It regulates pollen tube elongation and improves seed setting.
• Application: Spray during heading to maturity stages for optimal grain development.
• Effectiveness: Reduces sterility, increases seed setting rate, and improves grain quality, enhancing crop marketability.

5. Compound Foliar Fertilizers

• Characteristics: Contain balanced macro- and micronutrients (e.g., N, P, K, Ca, Mg) tailored to rice growth stages.
• Application: Apply regularly based on phenological stages and soil conditions.
• Effectiveness: Comprehensive nutrient supply supports healthy growth, increases yield, and improves grain quality.

Selecting suitable foliar fertilizers is crucial for maximizing rice yield and quality. Decisions should consider growth stage, soil properties, and target yields. Combining diverse formulations and concentrations ensures optimal results. Scientific fertilization practices promote sustainable agricultural development by enhancing crop resilience and resource efficiency.
