Unlocking High Potato Yields: Miftahul Huda’s Proven Fertilization Strategy
Miftahul Huda, a seasoned potato farmer from Desa Dieng Kulon, Batur, Banjarnegara, Central Java, has demonstrated remarkable success in potato cultivation, achieving a yield of 30 tons per hectare during the 2023 dry season. This surpasses the national average of 19.63 tons per hectare, showcasing the effectiveness of his strategic approach to fertilization.
Key Insights and Practices
Fertilization Techniques
Huda’s success is largely attributed to his precise use of fertilizers. He employs a combination of NPK Phonska Plus and NPK Petro Ningrat, adjusting the ratios based on seasonal conditions:
- Dry Season: 70% NPK Phonska Plus and 30% NPK Petro Ningrat (700 kg and 300 kg per hectare, respectively).
- Wet Season: 60% NPK Petro Ningrat and 40% NPK Phonska Plus (600 kg and 400 kg per hectare).
He also applies fertilizers in two stages: a base application of 600 kg and a follow-up application of 300-400 kg 30 days after planting. Additionally, Huda uses NPK Phonska Plus in a liquid form, mixed with humic acid and beneficial microorganisms like Trichoderma sp. and Bacillus sp. This approach is aimed at enhancing plant recovery and optimizing photosynthesis.
Yield and Quality
Huda’s methods result in high-grade potatoes, with a yield of grade AL (1-3 potatoes per kg) reaching 30% during the dry season and 10-15% during the wet season. This is notably higher than the grade regular potatoes (9-15 potatoes per kg). The superior quality translates to better market prices and a competitive advantage.
Challenges and Solutions
Huda’s farm faces challenges such as plant diseases and pests, including late blight and tuber moths. He combats these issues with fungicides and insecticides and uses mechanical support like stakes to prevent plant collapse. This integrated pest management ensures robust plants and a high-quality harvest.
Miftahul Huda’s approach to potato farming, combining advanced fertilization techniques with rigorous pest management, demonstrates a successful model for achieving high yields and quality. His use of NPK Phonska Plus has been instrumental in improving productivity and profitability, offering valuable lessons for other farmers. As Huda highlights, effective fertilization can significantly enhance crop outcomes, making it a critical component of successful potato cultivation.
