| This experiment was conducted during the growing seasons of (2005-2006) at the experimentel field of the Technical Institute/Musaib, to find out the effect of foliar nutrition by hubest (0.0, 1.0, 2.0, and 3.0 g/l) and NaCl (0.0, 0.5, 1.0, 1.5 and 2.0 g/l) on growth and yield of lettuce plant. This experiment designed factorial in (R.C.B.D) with (4) replicates. Results showed that (2.0 g/l) hubest resulted in a significant increasing of all characters studied, on the other hand NaCl in (1.5 g/l) led to a significant increase in leaf curl percentage, unbranched plants percentage,and non bloomed plants percentage. Interaction between of hubest (2.0 g/l) and NaCl (1.5 g/l) had a significant influence on yield and other qualities studied. However interaction gave highest mean of plant hight, leaf number, leaf curl percentage, non branched plants and non bloomed plants (104.1, 109.6, %96.9, %93.2, %96.6) respectively. This interaction, therefore had an obvions effect and increasing plant yield and early crop, and total yield (991.3, 3.866, and 14.791) respectively as compared with the control treatment |
