Agricultural Adaptation and Economic Outlook

• Winter Crop Cultivation: In areas less affected by floods, there is a push to expand winter crop cultivation, particularly short-season vegetables, to ensure food supply for Tết Nguyên Đán.
• Hải Phòng:
  • Plan: The province plans to cultivate 29,000 hectares of vegetables.
  • Cabbage and Kohlrabi: Farmers are already seeing significant profits. Mr. Năng received 200 million VND for two mẫu (approximately 0.72 hectares) of cabbage, with an average price of 10 million VND per sào (approximately 0.36 hectares). Due to widespread storms, traders are buying crops directly from fields.
  • Kohlrabi: Expected to be harvested in 15 days, with advance deposits already secured at 3,000 VND per plant.
  • Crop Rotation: Farmers can grow 2-3 crops of kohlrabi and about 2 crops of cabbage annually, significantly increasing economic returns compared to traditional rice cultivation.
  • Early Kohlrabi Harvest: Some farmers have started harvesting kohlrabi at prices around 8,000 VND/kg, higher than last year, with incomes of 7-9 million VND per sào. Mr. Hải earned nearly 200 million VND from kohlrabi in just 45 days.
  • Expansion: The joy of good prices is motivating farmers to expand winter crop areas. Over 30% of the planned area has been planted. Despite a later start, the target of 29,000 hectares is expected to be met.
  • Market Supply: Early winter crops like cabbage, kohlrabi, and leafy greens from Hải Phòng are already entering the market. With current market scarcity, farmers are achieving high incomes. All crops planted from September to now have secured purchase contracts. Many farmers are planning for a second planting.
  • Economic Impact: After the merger, Hải Phòng's winter crop area has tripled to over 29,000 hectares, with an estimated output of 1 million tons per year. The production value is approximately 6,902 billion VND, averaging 238 million VND per hectare. Winter crops are considered a "third golden season," significantly boosting income and economic efficiency.
• Overall Outlook: The success of winter crops in Hải Phòng is a bright spot, instilling confidence in farmers and contributing to food security for the upcoming Tết Nguyên Đán. The resilience and adaptability of farmers are highlighted as they find "golden seasons" even in difficult times, ensuring food supply for the nation.
