Field experimentwas conducted in spring season 2011-2012 in plastic house , in
Anbar Univ. Agric. Coll. Hort. Dept., to study the effect of potassium foliar
application in quantity and quality of two hybrid of melon(sembol, Angel) yield . 5
g/l K. application showed increase of fruit content of T.S.S and total sugar (18.887 %
, 17.958 %) to mean stem training affect on plant yield and total yield of plastic house
that reached (2.63 kg/plant and 2.052 ton/p.h). first hybrid was the best in fruit weight
(1.633 kg) second hybrid was the best in fruit content of T.S.S and total sugar (18.758
% and 17.985 %).
