dc.description.abstractThe potato, Solanum tuberosum L. is second only to wheat in importance as a food crop in New Zealand. During the last five years the total area of potatoes grown has fluctuated between 8,000 and 10,000 hectares, and the yield has increased steadily to over 25 tonnes per hectare (Table I). Table I Potato production in New Zealand. Area and production for several recent seasons*.

(Yield figures converted to metric equivalents). **= 10.15 tons/acre Although potatoes are grown in all parts of New Zealand, the bulk of the market is supplied from three areas. The Pukekohe district supplies the early markets from September to December and also substantial quantities of mid-season and main-crop potatoes. The February to July market is supplied principally from the Manawatu-Rangitikei district, and winter supplies (May to November) are drawn mainly from Canterbury, Otago and Southland (Claridge, 1972; Baxter, 1972).
