In recent years, taro has become increasingly popular in food processing and the catering industry due to its rich nutritional value and versatile culinary uses. As market demand continues to rise, taro cultivation in China has steadily expanded, with continuous improvements in cultivation techniques leading to higher yield and quality.

In Beipo Town, Leizhou City, Guangdong Province, taro farming is a key local industry. The region contributes over 50% of the total taro planting area in Zhanjiang, which spans about 150,000 mu. Taro is typically planted in October and harvested the following May, with yields reaching 1,500–2,000 kg per mu. At a current purchase price of 6 yuan/kg, this equates to a gross income of 9,000–12,000 yuan per mu, offering significant economic returns.

This article explores the application performance of Nitrophoska® compound fertilizer in taro cultivation.

Fertilization Plan

Taro is typically fertilized by broadcasting or trench application, which is well-suited to the granule design of Nitrophoska® compound fertilizer. Below is the fertilization plan tested in Beipo Town, Leizhou City.

(Note: Fertilizer quantities are measured in kg per mu)

Significant Field Performance Advantages

🌱 Promotes Root Development

Field comparisons showed that taro fertilized with Nitrophoska® developed much more robust root systems than those with conventional fertilization. The roots were denser, with more white roots observed. A strong root system acts as the "mouth" of the plant, improving nutrient and water uptake — the foundation of healthy taro growth.

🌿 Increases Stem Thickness

Nitrophoska® fertilizer significantly increased stem diameter. Measurements from 10 randomly harvested plants showed an average stem diameter of 9.1 cm with Youken®, compared to 8.4 cm with traditional fertilization — an 8% increase. Thicker stems support stronger above-ground growth and improve the plant’s resistance to lodging (falling over).

🍃 Improves Leaf Area & Increases Yield

Nitrophoska® fertilizer also improved leaf area, which in turn led to higher yields. Based on weight measurements from 10 randomly harvested taro bulbs, the Nitrophoska® treatment achieved an 11.7% yield increase and net income improvement of 1,356 yuan per mu.

Conclusion

Overall, Nitrophoska® compound fertilizer performs excellently in taro cultivation. It:

• Promotes strong root development, enabling deeper rooting and improved nutrient uptake.
• Increases stem thickness, enhancing plant strength and lodging resistance.
• Expands leaf area, leading to significantly higher yields and increased income for growers.

If you're involved in taro farming, trying out Nitrophoska® compound fertilizer could bring you unexpected and rewarding results.
