Agriculture Reporter POTATO is a high input, high returns crop with certain demands on production know-ledge and skills.

Determine plant spacing. l Sprout seed and prepare land. Fumigate soils (optional). l Harden the sprouts under diffuse light. l When seed is ready for planting make final land preparations. l Open furrows and apply all basal fertiliser requirements. l Slightly cover the fertiliser. Irrigate to moisten soil for planting. (Both operations are optional ). l Treat soil with nematicide (for nematodes). l Place seed in furrows at the determined spacing. l Treat soil against white grub and wireworms (optional) l Cover seed to attain flat surface l Irrigate to field capacity l Once soil moisture allows, inspect and cover exposed seed tubers. l When crop starts emerging, check for pests and diseases. l Follow irrigation schedules. l Two to three weeks after emergence, apply top dressing and ridge the crop. l Top dressing at this time should not exceed 130kg (40kg) Ammonium Nitrate per hectare.
