Potato Growers: Use Complex Fertilizers, Plant Deep, Protect Against Blight
Potato growers are advised to use complex fertilizers and follow specific planting techniques to ensure a successful harvest. Recent research has highlighted the importance of balanced nutrients, proper depth, and timely protection against late blight.
To begin, it's crucial to use complex fertilizers with balanced nitrogen, phosphorus, and potassium. These promote healthy growth and yield of plant cells. Plant potatoes about 7-10 cm deep, adjusting for soil type and climate. Deeper planting can lead to abundant foliage but small tubers.
For disease prevention, plant breeders use copper sulfate or Bordeaux mixture. Treating tubers before planting and spraying foliage at the start of the growing season protects against late blight. It's also beneficial to plant medium-sized tubers, or cut larger ones into pieces with several eyes.
Organic fertilizers like fresh manure should be avoided as they can negatively impact the taste of house plants. Breaking the tops of potato stems 1-2 weeks after flowering redirects resources to developing larger tubers. However, smaller seed tubers generally produce more small tubers, while larger ones stimulate abundant foliage but result in smaller tubers.
In summary, using complex fertilizers, planting potatoes at the right depth, treating tubers with copper sulfate or Bordeaux mixture, and breaking the tops of stems at the right time can lead to a successful potato harvest. By following these guidelines, growers can protect their crops from disease and ensure a bountiful yield of roasted potatoes.
