Effect of some cultural practices on cauliflower tolerance to salinity under ras suder conditions [electronic resource].

Includes reference.

Cauliflower (Brassica oleracea var. botrytis) plants cv Toobi was cultivated during two successive seasons (2004-2005 and 20052006). 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, Le., 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.
