EFFECT OF SOME CULTURAL PRACTICES ON CAULIFLOWER TOLERANCE TO SALINITY UNDER RAS SUDER CONDITIONS

Document Type : Original Article

Abstract

Cauliflower (Brassica oleracea var. botrytis) plants cv Toobi
was cultivated during two successive seasons (2004-2005 and 2005-
2006). The experiment was conducted at the Experimental Farm,
Desert Research Center, Ras Suder Region, South Sinai Governorate,
Egypt, to study the effect of ridge height (25 and 50cm) and magnetite
level (0, 50, 100, 150 and 200 kg/fed) on the growth and yield. The
obtained results indicated that growing cauliflower plants on the high
ridge planting method affected positively the vegetative growth, curd
weight, total yield, and nitrogen, phosphorus, potassium and iron
contents in leaves and curds, but decreased sodium and chloride
contents in leaves and sulphur contents in leaves and curds . Results
also indicated that increasing magnetite levels led to increase the
vegetative growth characters, curd weight, yield and mineral
concentrations, i.e., nitrogen, phosphorus, potassium and iron in
leaves and curds, but decreased sodium and chloride contents in
leaves and sulphur contents in leaves and curds. The highest yield was
produced when 200 kg magnetite/fed was added combined with using
the high ridge planting method.
