Boosting Rice Yields with Nutri Haitech™ Fertilizer Products & Solutions
Rice, a staple food for over half the global population, requires precise nutrient management to ensure optimal yields and grain quality. Haifa Group offers a complete range of nutritional solutions tailored to the needs of rice crops, helping farmers increase productivity and sustainability.
Haifa’s rice fertilizer programs emphasize strategic, crop-specific fertilization—particularly nitrogen, potassium, zinc, and silicon—combined with foliar applications at critical growth stages. These practices are brought together under Haifa’s pioneering Nutri Haitech™ approach, which delivers complete nutritional solutions for precision agriculture. Designed to enhance both sustainability and efficiency, Nutri Haitech™ minimizes waste and environmental impact—while significantly improving rice yields.

Understanding Rice Nutritional Needs
Nitrogen
Nitrogen (N) s fundamental to rice development, influencing plant height, leaf size, panicle formation, and grain filling. Rice exhibits an S-shaped (sigmoidal) nitrogen uptake curve: uptake is slow during early growth, then becomes steady and rapid from tillering to the milky stage—critical phases for yield determination—before gradually declining as the crop approaches maturity.
In flooded paddies, nitrogen is highly susceptible to losses through ammonia volatilization, denitrification, leaching, and runoff. With conventional granular fertilizers, nitrogen recovery rarely exceeds 30–40%. Haifa’s controlled-release fertilizers, such as CoteN™, align nitrogen release with crop demand, significantly enhancing nitrogen use efficiency and reducing environmental losses.
To optimize nitrogen management throughout the season, it is recommended to use the Croptune™ mobile app, which provides real-time nitrogen status assessments and actionable fertilization recommendations.

Potassium
Potassium (K) plays a vital role in rice physiology, supporting enzymatic activity, photosynthesis, water regulation, and sugar transport. Adequate potassium nutrition strengthens the plant’s resilience to drought, salinity, and disease, while significantly improving grain filling, size, and weight—all crucial for achieving high yields and marketable quality.
Like nitrogen, potassium uptake in rice follows an S-shaped pattern, with most absorption occurring between tillering and panicle initiation (30–60 days after sowing). Under common commercial practices, considerable amounts of potassium are removed from the field through harvest, making K fertilization essential. Field trials have demonstrated that proper potassium application can boost yields by up to 20%.
To meet the plant’s dynamic potassium demands, foliar applications of Haifa Bonus™ are highly recommended, especially during key reproductive stages.
Zinc
Zinc (Zn) is the most widely required micronutrient, playing key roles in photosynthesis, protein synthesis, growth regulation, and reproduction. Rice is particularly susceptible to Zn deficiency, as it grows in waterlogged soils which are conducive to zinc deficiency. Flooding the soil reduces Zn availability to the crop and increases the concentrations of soluble P and bicarbonate ions, which can exacerbate problems of Zn deficiency.
Zinc deficiency is also common in lowland rice, especially in high-pH, silt, and sandy loam soils, leading to stunted growth, leaf bronzing, and reduced tillering.
Haifa’s zinc-enriched products ensure this vital element is available in the right form, at the right time.

Silicon: A Key Ingredient in Plant Strength
Though not considered essential, silicon greatly enhances rice plant performance. It fortifies cell walls, improves structural integrity, and increases tolerance to pests, diseases, and abiotic stresses. Haifa’s Poly-Feed™ Stim Armor and Haifa Stim Wall-up provides a highly efficient source of silicon alongside mineral nutrition, promoting stronger, healthier plants.

Technical Challenges in Rice Crop Fertilization
Flooded rice fields present unique challenges in nutrient management. Nutrient leaching, volatilization, and reduced soil oxygenation can limit nutrient uptake and reduce efficiency. Haifa offers advanced solutions tailored to these conditions:
- Controlled-release fertilizers, like CoteN™, ensure continuous nitrogen supply throughout the season, significantly improving nitrogen use efficiency even in flooded fields.
- Foliar nutrition is the most effective way to deliver essential nutrients precisely when the plant needs them most—particularly under conditions where root uptake is compromised.
It is recommended to apply foliar fertilizers such as Haifa Bonus™ and Poly-Feed™ Stim during critical growth stages, e.g. tillering and panicle initiation
Conclusion
A carefully managed fertilization approach—integrating nitrogen management, potassium support, zinc supplementation, silicon enrichment, and strategic foliar feeding—is essential to achieve high rice yields and quality. Backed by agronomic expertise and innovative products, Haifa Group’s Nutri Haitech™ solutions provide the tools growers need for efficient, sustainable rice production.
