Abd Eldaiem1, M.A.M. and M.A.B. El-Sherief ( 2016). Effect of organic, phosphorus and zinc fertilization on yield and quality of flaxInt. J. Adv. Res. Biol. Sci. (2016). 3(1): 161-173
Abstract: Organic, phosphorus and zinc fertilizations were proved to affect the straw, seed and fiber yields of flax. Therefore, two field
experiments were conducted at the Experimental Farm of Gemmeiza Agriculture Research Station, El-Gharbia Governorate, Agricultural Research Center (ARC), Egypt, during 2012/2013 and 2013/2014 winter seasons to determine the effect of organic,
phosphorus and zinc fertilization on yield and quality of flax. The experiment was conducted in split-split plot design with three replications. The main-plots were included farmyard manure (FYM) levels. The sub-plots were devoted to phosphorus fertilizer
levels. The sub sub-plots were allocated to three levels of zinc in the form of Cheleated Zinc 13% as foliar application. The highest values of all studied characters were obtained by organic fertilized flax plants with the highest level of FYM (20 m3/fed). Maximum means of all studied characters were resulted by fertilizing flax plants with 30 kg P2O5/fed in both seasons. Foliar spraying flax plants twice with 500 ppm zinc significantly surpassed other zinc levels and produced the highest values of all studied characters in both seasons. It could be concluded that best yield and quality of flax could be obtained in case of organic fertilized flax plants with 20 m3 FYM /fed and 30 kg P2O5/fed besides foliar spraying twice with 500 ppm zinc under the environmental conditions of Gemmeiza district, El-Gharbia Governorate.
