| Abstract | ||||
| Micronutrients foliar application is much better than soil application to avoid not only nutrients fixation in the soil, but also leaching during irrigation. Two field experiments were carried out at El-Gimmiza Agricultural Research Station during the two successive growing seasons of 2005/2006 and 2006/2007 to study the effect of foliar application of the micronutrients(Fe, Mn, Zn and Cu) in a mixture on yield, yield components and seed chemical composition of lentil plant (lens Culinaris. Medic). The foliar treatments applied were: T1 ( 0.0 micronutrients), T2 (0.5 g/L micronutrients), T3 (1.0 g/L micronutrients) and T4 (2 g/L micronutrients).The obtained results revealed that spraying micronutrientsat rate 0.5 g/L (T2) increased yield and yield components such as: plant height (3.1%), number of branches (7.8%), number of pods/plant (15.9%), seed yield/plant (30.8%), 1000-seed weight (9.4%) and seed yield (10.2%)as well as seed contents of protein (9%), K (31.1%), Fe (21.4%), Zn (12.3%), Cu (8%) and Mn (13.6%)compared with the control (T1 ). The application of micronutrients at rate 0.5 g/L (T2) caused significant increase in yield and yield components compared with other treatments. Meanwhile T4 (2g/L) gave significant decreases in most studied traits compared to T2. Also, the highest values were recorded with variety of Giza 4 than Sina 1 in all treatments during the two growing seasons. | ||||
