Abstract

Two successive field trials were performed at the Agricultural Research Farm of the Faculty of Agriculture, Suez Canal University during the two successive of 2018/2019 and 2019/2020. to investigate the influence of 0, 0.5 and 1 mM of indole 3-butyric acid (IBA) and 0, 1, 1.5 and 2 mM myo-inositol (MI) and their interactive as folair application on vegetative growth, bulb yield, biochemical constituents and mineral contents of garlic plants cv. Seds 40. The treatments were laid out in a split plot order with three replicates. The obtained results reported that garlic plants positively responded to the exogenous treatments of IBA and MI individually or interactively. It showed generally that application of IBA at 0.5 mM recorded the highest values of vegetative growth, yiled, quality parmemters as well as the mineral content (N, P and K). In the same regard, application of MI at 1.5 and 2 mM significantly promoted moast of studied traits compared to control and the rest of MI concentration, in both growing seasons. Furthermore, the two-factor interaction was found to be significant for all measured traits in both seasons, except for K content. Whereas, exogenous treatment of IBA at 0.5 mM along with exogenous treatment of MI at 1.5 and/or 2 mM resulted in the highest means of most of the above mentioned traits. Thus, it could be suggested that applying a combination of IBA and MI was found to be effective for enhancing vegetative growth, bulb yield  and quality as well as macro-elements content.
