A study of various planting methods on tuber yield of sweet potatoes (Ipomoea batatas, Poiret) in Papua New Guinea

Abstract

The traditional method of land preparation and planting of sweet potato in PNG was compared with a typical method used in Taiwan and the other Asian countries. The results were analysed to determine the performance of various techniques used within the two methods. The results of the trial are discussed and specific points of interests are highlighted. Recommendations are drawn from this to apply on the [Taiwan Agricultural Technical] Mission's extension farms in PNG and also as broad recommendations for traditional sweet potato growers in PNG.
