| Abstract | ||||
| Two field experiments were carried out during the two successive winter growing seasons of 2013 and 2014at the Experimental Farm of the Environmental Studies and Research Institute, University Sadat City to study the effect of natural ores and foliar spray treatments on bulb yield and its components, chemical composition , bulb quality as well as phytopathology of two onion (Allium cepa L.) cvs. Giza 20 Giza Red grown under sandy soil conditions. Natural ores treatments (mixed) were added to the soil before planting at rates of 500kg. per fed., while the foliar spray treatments were sprayed in growth season with recommended dose as follows, Biophertel Ore at 10 cm3 / letter, Biocide Ore at 5 g / letter , Bentocide Ore at 10 g / letter, Ammonium nitrate liquid (33%)at 0.5 liter / 50 L of water. A randomized complete blocks design with three replicates was used. The results showed that, cv. Giza 20 significantly gave the highest values in most of all tested parameters i.e., yield and yield components, bulb quality, mineral contents of bulbs as well as phytopathology than cv. Giza Red during both seasons. In addition, fresh weight of bulb, total yield per fed., marketable yield, quality of bulbs (mean shape index, number of episode circular and T.S.S %) and chemical composition of bulbs were significantly increased by using natural ores (abd+mix.) , while phytopathology significantly affected by adding natural ores mixed at the soil than other treatments. The interaction between the cultivars and natural ores was not significantly effected in all parameter of study in both seasons. | ||||
