OBSERVATIONS ON APPLE AND PLUM PERFORMANCE AND RESPONSE TO GROWTH CONTROL TREATMENTS AT THREE CLIMATICALLY DIVERSE SITES IN ETHIOPIA |
| Authors: | Robert P. Rice Jr, S. Becker |
| Abstract:
Several cultivars of apples and plums were planted at 3 climatically diverse sites in Ethiopia in 1976. Sites varied in chilling units received, mean temperatures, rainfall, and time of year when chilling temperatures occurred. In 1977 trees were evaluated and various treatments including pruning, branch bending, and withholding of irrigation were applied. The response of the trees could not be predicted by temperature alone. Withholding of irrigation assisted in synchronizing flowering at one site. Branch bending in apple increased lateral bud break and increased fruit production. Trees at all sites have produced some fruit. Observations continue. | |
