A field experiment was carried out during the two successive winter seasons of
2016/2017 and 2017/2018 in a private Farm at Hehia Distrect, Sharkia Governorate, Egypt, to study
the effect of planting date, and foliar spray with potassium silicate on dry weight, bulb yield and its
components of Balady and Sids 40 garlic cultivars under clay soil conditions and using flood irrigation
system. The obtained results indicated that planting Balady cultivar on 1st Oct. and spraying with
potassium silicate (K silicate) at 2 ml/l increased dry weight of leaves/plant, bulb and total dry
weight/plant, yield of grades 1, 2, 3 and 4, exportable, marketable and total yield/fad., as well as
average bulb weight.
