((IMPROVING YIELD, QUALITY AND STORAGEABILITY OF GARLIC (Allium sativum L.) BY PRE-HARVEST FOLIAR APPLICATION))

Abstract

An experiment was conducted at Siwa oasis Research Station, Desert Research Center (Khimisa Farm) during the two consecutive seasons of 2013-2014 and 2014-2015, to evaluate the effect of some foliar spray treatments (Calcium, Potassium, Salicylic acid ,Chitosan, and Menthol) on growth, yield, quality and strogability of garlic. Results revealed that chitosan, potassium and salicylic acid increased growth characters, yield and its component when compared with calcium, menthol and the control treatments in both seasons. Also, chitosan enhanced calcium, potassium, TSS and L ascorbic acid content at harvest compared with other treatments. During storage period weight loss and decay percent of bulbs were reduced with calcium, chitosan and potassium treatments when compared with other treatments.
