Improving Wheat Production and Grain Quality By Inorganic, Organic and Some Micronutrients Fertilizers Under Saline Condition

Two field experiments were conducted during two successive seasons in 2007/2008 and 2008/2009 at Gelbana district Sahl-el Tina plain (North Sinai) to study the response of two Egyptian wheat varieties namely Sakha 93 and Sids 1 to inorganic, organic and foliar spray with micronutrients either solely or in mixture combination. Split plot design was used for the experiment design wheat plants were sprayed twice with mixture of Zn +Mn +Fe at a rate of 0.3g Zn EDTA +0.3g Mn EDTA +0.3g Fe EDTA, one sprayed at tillering stage (30 dys from sowing) and the secondly at the head development stage (70 days from sowing). It was found that NPK fertilizer was more effective than compost or micronutrients mixture (Fe +Zn +Mn) in increasing wheat yield and yield components of both studied varieties. Sakha 93 was more affected by this treatment and surpassed Sids 1 in all growth characters except plant height Corresponding increases in macronutrients (NPK) and micronutrients (Fe+Zn+Mn) in wheat grains .NPK treatment produced high significant effect in crude protein % and total carbohydrates in grains, shoot length, radical length, EC and seedling dry weight for both studied varieties. While germination percent, was not significant for varieties, treatments and inter action between varieties and treatments. The obtained data declared that the combination treatment NPK+compost +Fe+Zn+Mn produced highest significant increases for all studied characters except germination percent for Sakh93 and Sides1 wheat. Also Results revealed that applied fertilization treatments led to increase in pH and Ec soil and increase in available macro- and micronutrients soil content compared with initial soil .In conclusion the present study droves that the use of following order NPK+compost +EDTA> NPK +compost > NPK +EDTA> NPK was successful in improving wheat productivity under saline.
