Growth and yield of four accessions of North Maluku local sweet potato in three different locations

Abstract

The accession of North Maluku sweet potato is quite a lot and has the opportunity to be developed as a local national variety. The aim of the study was to obtain local North Maluku sweet potato accessions which had good growth and production and were adaptive in various locations. The research was conducted in three locations, namely East Halmahera, West Halmahera, and Tidore Islands from March to July 2016 using a randomized block design, consisting of 4 accessions of local sweet potato (Halteng-1, Halteng-2, Halut-1, and Halut-4), repeated 5 times. The results showed that the vegetative growth of the four accessions differed in each location. The difference lies in the length of the stem, stem diameter, number of leaves, and the length of the petiole. In the yield component, the difference is in the weight and length of the tubers. The four sweet potato accessions are not stable yet planted in various agro-ecologies.
