Effect of Alar, Cycocel and Bonzi and Their Method of Applications on Growth Performance of Ivy Geranium (Pelargonium peltatum)

Kebede Tedila

This green-house experiment was conducted to determining the growth response of Pelargonium peltatum to application of Alar, Cycocel and Bonzi spray and drench applications. On the test plants it was observed that the application of Alar, Cycocel and Bonzi considerably affected most of the evaluated parameters except the number of roots. Alar, Cycocel and Bonzi reduced the height of the test plant and branching habit was induced in all combinations. Accordingly, the highest number branch per plant was obtained from plants treated with Bonzi in drench application however the respective lost number of branches per plant was recorded from plants which did not receive plant growth retardant chemicals. In general the investigations entail that Alar, Cycocel and Bonzi can influence growth of Pelargonium peltatum and cutting yield (branching). From commercial grower point of view, obtaining large number of quality cuttings is crucial. Hence application of Bonzi in drench form demonstrated positive influence on cutting production can be recommended for use by commercial growers in Ethiopia.
