Potassium and Zinc in Relation to Improve Flax Varieties Yield and Yield Components as Grown under Sandy Soil Conditions

Abstract

Two field experiments were carried out at the experimental station of National Research Centre, Al-Nubaria District, El-Behira Governorate, Egypt during winter seasons of 2011/2012 and 2012/2013 to study the effect of potassium soil application at the rates (0, 50, 75 and 100 kg/fed.) with or without chelated zinc foliar application 5% at the rate of (0.03 kg/fed.) on the yield and quality of two flax varieties (Sakha-2 and Amon) in newly reclaimed sandy soil. The obtained results could be summarized as follow: Sakha-2 variety significantly surpassed Amon in plant height, technical length, number of branches/plant, seed yield/plant, straw yield/plant, 1000 seed weight, seed yield/fed., straw yield/fed., fiber %, fiber yield/fed. and oil yield/fed. Amon variety surpassed Sakha-2 in fruiting zone length, number of capsules/plant and oil % in both seasons. Potassium soil application at the rate of (100 kg/fed.) with chelated zinc foliar application 5% at the rate of (0.03 kg/fed.) gave the highest value for all studied characters.
