In: Mansoura University Journal of Agricultural Sciences 2007.v.32(9)Summary: A field experiment was conducted at Lattakiia during the two successive seasons of 2005-2006 to study the effect of mineral and organic fertilizers on yield and NO2 and NO3 contents in spinach leaves. The results showed that spinach leaves in the first and second cut were free from NO2 in case of aU treatments used. Moreover. the results indicated that application of Urea and organic fertilizers gave rise to highest yield with less N02. Ukewise, application of balanced solvable (N:P:K) gave a moderate yield and less NO, content. On the other hand, ammonium nitrate and ammonium sulfate led to less productivity and on olives increase in NO3 spinach leaves.
