As global food security faces increasing challenges, innovation in agriculture is becoming ever more critical. Haifa's Poly-Feed™ Stim, which provides a unique combination of mineral nutrition and biostimulants, helps improve yields and enhances plant resilience, offering a practical approach to increasing the efficiency of rice farming.
Rice is a staple food for over half of the world's population, yet production struggles to keep pace with growing demand. Recent geopolitical and climatic events have exacerbated this challenge. With food security under increasing strain, finding ways to enhance rice production has become essential.
Poly-Feed™ Stim: A Targeted Nutritional Solution
Poly-Feed™ Stim combines essential mineral nutrients with biostimulants to improve rice crop performance. Designed to address the specific nutritional needs of rice, this solution enhances plant strength, increases yield potential, and improves overall crop resilience.
Silicon: A Key Ingredient in Plant Strength
By improving plant cell structure, silicon helps rice plants maintain sturdier stalks, leading to better growth and increased productivity. Silicon also enhances the rice plant’s resilience to various abiotic stresses and facilitates the uptake of essential nutrients.
A crucial aspect of Poly-Feed™ Stim Armor is the inclusion of fully soluble stabilized silicic acid, which ensures high availability for plant uptake. Unlike other silicon products that may contain sodium or have an unsuitable pH for crops, Poly-Feed™ Stim Armor features a neutral pH and is sodium-free, ensuring high efficiency with minimal quantities required to deliver measurable benefits.
Proven Results
In a field trial conducted by Haifa agronomist Red Zhang , the foliar application of Poly-Feed™ Stim Armor led to a 14.2% increase in rice grain yield and a 19.3% increase in grain weight. These results demonstrate the potential of targeted fertilization to enhance crop performance and provide a more resilient yield.

Practical Benefits for Rice Farmers
By incorporating advanced formulations like Poly-Feed™ Stim into rice farming practices, growers can achieve both higher yields and enhanced crop resilience. The use of fully soluble silicic acid ensures that plants receive silicon in its most effective form, contributing to improved structural integrity and overall health.
While the trial results are encouraging, it’s important to note that the benefits of Poly-Feed™ Stim Armor extend beyond yield increases. The improved mechanical strength of the plants and enhanced resilience to environmental challenges provide valuable support to farmers in regions facing unpredictable weather and other stress factors.
