Abstract
Increasing garlic yield and improving bulb quality are essential aims for growers to fulfill the requirements of the market and the
consumers. Two field experiments were carried out during two successive seasons; 2010/2011 and 2011/2012 at a private farm to
find out the influence of some bio-stimulants i.e., ascorbic acid, dry yeast, amino acids (Ruter and Total), seaweed extract (Alga 600)
and Spirulina extract (Arthospira fusiformis) on plant growth, yield, yield components and storability of garlic plants "Balady"
cultivar. One month after planting, foliar applications of bio-stimulants were applied, and repeated 3 times at 15 days intervals
throughout the growing season. The design of the experiment was a complete randomized blocks (CRB) with three replicates. Results
indicated that foliar application of Amino Total (1.2 ml l-1
) effectively increased plant height compared to all treatments and control.
Number of leaves per plant was the least (9 and 9.5) in control plants in both seasons. Application of yeast (2 g l-1
) or amino total
(1.2 ml l-1
) showed the heaviest bulb weight (67.7, 72.0 and 69.5, 66.6 g) in the first and second season, respectively. Weight loss of
bulbs was the least with the application of ascorbic acid
