Nitrogen fertilizer needs to be supplied to promote seedling growth when plants start to grow fast during the rosette stage. Common formula fertilizers or NPK 25-0-4 granular fertilizers are recommended.
NPK 16-6-32 water soluble fertilizer is recommended for fertilizing through irrigation.
The tillering stage refers to the period from rosette to the blossoming of the first flower when both parts of the plant (above and below ground) grows at the same pace. The stem then grows taller, faster, with the emergence of branches and leaves. Nitrogen control should be noted when fertilizing at this stage in order to avoid prosperous plant growth from being affected by the tuberization of the potatoes. NPK 16-8-18 granular fertilizer combined with cultivation and banking is recommended. Potato blossoming signals the start of the tuberization stages, and indicates that nutrition needs to be carried to the tuber. A fast acting potassium fertilizer that provides quick results is recommended at this stage. We recommend NPK 16-6-32 water soluble fertilizer.Solutions:
