A time of planting trial with sweet potatoes


  • D.E. Gollifer Department of Agriculture, Solomon Islands


Results of a time of planting trial with sweet potatoes, based on five successive years, indicate that tuber yields were highest between September and February at Dala, Malaita, in the Solomon Islands. The smallest tuber yields were associated with growth during the period of highest rainfall. Tuber and vine yields were negatively correlated. There were positive correlations between the yield of tubers and solar radiation and between the yield of vines and rainfall. Tuber yields and rainfall were negatively correlated.
