In: Annals of Agricultural Science, Moshtohor 2012.v.50(4)Summary: Studies were conducted under greenhouse conditions to find the relations between pruning methods and chosen parameters of vegetative aubergine development. Two field experiments were carried out during the two successive winter seasons of 2009/2010 and 2010/2011 at the Agriculture Experimental Station Faculty of Agriculture — Cairo university at Giza to study the effect of pruning method on growth, fruit yield and quality of cvs Fabinia ‘, ‘Roma and Snow of eggplants (Solanum melongena L.) grown in the greenhouse. The following pruning systems were applied: plants were either left unpruned as a control ,pruned at the every node fruit set, pruning to every node one fruit set and pruning to every node two fruit set to study the response of three eggplants cultivars, A split plot design with three replication was used where the three eggplants cultivars were located in the man plot, while three pruning systems were randomly applied in the sub plots. The highest records of plant height and number of leaves as well as early and total produced yield fed., were obtained by the combined effect of cv. Snow eggplant and pruned at the every node two fruit set followed by cv. Snow and pruned at the every node one fruit set. On the other hand, the lower values of plant height and number of leaves as well as early and total produced yield! fed., were obtained by the combined effect of cv. ‘ Fabinia ‘ without pruned in both seasons. The highest values of physical characteristics i.e. Fruit length, diameter and weight and chemical characteristics i.e. TSS were obtained by the combined effect of cv. • Snow ‘ eggplants and pruned at the every node two fruit set followed by cv.’ Snow ‘ and pruned at the every node one fruit set in both seasons. Finally it could be concluded that the combined effect of cv. Snow ‘ eggplants and pruned at the every node two fruit set was recommended for higher yield with good quality of eggplant.
