Abstract

     Two field experiments were conducted during the two successive seasons of 2009/2010 and 2010/2011 in Sherben District, Dakahlia Governorate to study the interaction effects of organic fertilization types , nitrogen and potassium applications on yield , yield components and nutrient contents of wheat crop (Triticum aestivum L.). Two types of organic fertilizers ( FYM and compost) , four levels of N-fertilization (0 , 60, 80 and 100 kg N fed-1) and three levels of K-fertilization (0 , 50 and 100 kg K2O fed-1 ) were examined .The experiment was conducted in a split split plot design. The obtained results indicated that the integrated treatment of 100 kg N fed-1+ 50 kg K2O fed-1and 14 ton fed-1 FYM produced the highest means of grain and straw yields and also improved the values of N,P and K concentration in plant tissues ,which could be recommended under the conditions of  this experiment.
