Two field experiments were carried out at El-Ismailia Agricultural Research Station, El-Ismailia Governorate during the two winter growing seasons, 2005/2006 and 2006/2007 to study the effect of sprayed zinc as chelate form at rates of control, 0.5, 1.0, 2.0 and 3.0 g/Liter on yield components, yield and chemical composition of lentil plant (Lens culinaris, Medic.) grown on sandy soil. Results can be summarized as follows: Generally, foliar application of zinc achieved significant increases of lentil yield and its components, as compared with control treatment received no zinc in both growing seasons. Spraying zinc at rates of 1.0 & 2.0 g/liter led to significant increases in most parameters of yield and its components, compared to the other treatments in both seasons. Meanwhile, zinc at the rate of 3.0 g/liter gave significant decreases in the most parameters. In first season, in most cases, zinc foliar application at the rates of 1.0 and 2.0 g/liter increased significantly macro and micro nutrient contents in seed lentil plants, compared to the other treatments. Meanwhile, the control treatment and zinc application at the rate of rate of 3.0 g/liter decreased significantly such nutrients. On the other hand, foliar application at the rates of 1.0 and 2.0 g/liter increased significantly N & protein percentages. While, zinc addition did not significantly affect P& K percentages, as well as Fe, Zn and Mn concentrations in the second season.
