Abstract

Two field experiments were carried out during two successive summer seasons of 2014 and 2015 at Vegetable Private Farm located on Faqus District, Sharkia Governorate, Egypt, to study the effect of the sources of potassium fertilization such as (potassium sulphate (K₂SO₄), potassium citrate (KC), potassium thiosulphate (KTS) and potassium glysrophosphate (KGP), beside control treatment (water) on growth, yield and fruit quality of some cantaloupe hybrids (Galia, C8 and Gal 152): Spraying Galia or Gal 152 with KTS or KGP gave the highest values of dry weight of shoots and total dry weight/ plant, total acidity and Vitam. C in fruits. Foliar spray of C8 hybrid with KTS increased yield/plant, early yield, marketable yield and total yield/fad., followed by spray of Galia with KTS in both seasons with respect to marketable yield and total yield
