GROWTH PERFORMANCES OF EVERBEARING STRAWBERRIES IN KENYA

Authors:   K. Waithaka, C.W. Ngugi
Abstract:
Insufficiency of propagation material has hampered strawberry production in Kenya. Propagation is mainly by crown division because the continuous short-day conditions in the tropics favour branch crown development over runner production. Continuous crown division and flowering has resulted in a decline in vegetative growth of the available strawberry cultivars. There is reduced plant growth during the short rains season and especially when plants are planted during the cool months of June, July and August. Physical manipulation of the parent plants proved a little beneficial in runner production in a few everbearing cultivars. Defoliation of the older leaves promoted runner production in cvs Turft and Tioga in both long and short rains seasons. The number of daughter plants produced was directly proportional to the number of runners formed in all cultivars. Deblossoming promoted runner production in Turft but failed in cvs Tioga and Aiko. All treatments failed to promote runner production in Aiko. Irrespective of the treatments, Turft was the most vigorous of the cultivars used in the study. Petiole length was not influenced by any treatments in all cultivars and petioles were significantly longer during the long rains season.
