Growth and yield of seven apple tree ( Mains domestica Borkh .) cultivars were compared in threealtitudinalrnzones in Game Gofa , at Chencha , Bonke and Boreda, Southern Regional State , Ethiopia, tornrelate crop growth and yield with altitude. The seven cultivars, BR-64, Granny Smith , Gala , Anna, GoldenrnDelicious, Red Delicious and Crispin were of similar age, had identical rootstocks and were growing atrnthe same site in each altitude under similar management practices. Data on new shoot growth , leaf area,rnheight, stem diameter, number of fruits and fruit size were collected and 60 home gardens of the applerngrowers were surveyed. Interview's were conducted and questionnaires administrated in order to getrninformation on the practice of apple growers and their perception. The result showed that , more than halfrnof the area of home gardens of the apple growers were used for apple cultivation for income generationrnand for domestic consumption. Farmers indicated that the expansion of the crop was related to the highrnprice of the fruit, in Chencha and Bonke the number of BR-64, Granny Smith and Gala was more thanrnthat of Anna and Golden Delicious. The latter cultivars were not widely planted due to their lower yield atrnthe two sites. Anna and Golden Delicious were better in Boreda than in Chencha and Bonke. Farmersâ€™rnselection of cultivars were based on experience on yield performances. On the other hand, most farmersrnshowed limited knowledge of rootstocks used , cultivar selection at different sites, pruning and thinningrnactivities. Further, management practices such as mulching and manuring at proper time of cultivars newrngrowth and blooming at Fall ( tsedey ) was not performed . Similarly knowledge of apple diseases and pestsrnthat reduce yield was not apparant and little traditional methods of prevention were usedrnOf the seven cultivars BR - 64 , Granin Smith and Gala grafted on MM 106 rootstock showed an increasernwith altitude in new shoot grow th, leaf area , stem diameter and fruit number. Both in Chencha and Bonkernthese cultivars shaded their leaves early in June and resumed blooming and leafing in September. ForrnAnna and Golden Delicious the same parameters decreased with increase in altitude. The results indicaternthat while Anna and Golden Delicious were suited for warmer climates, BR-64 , Granny Smith and Galarnâ€¢were more suited for colder climates.rnRed Delicious and Crispin had moderate growth and did not show altitude preference. It is recommendedrnthat selection and distribution of apple seedlings should be altitude specific based on the preference of therncultivars.
