| Abstract | ||
| This experiment was conducted during the growing seasons of (2012 - 2013) inside unheated plastic house at the experimentel field of the Technical Institute/Musaib to investigate the effect of sprays number and concentrations of nutrition by hubest (0.0, 0.5, 1.0, 1.5 and 2.0 cm3 .l-1) on growth and yield of lettuce plants .This experiment designed factorial in (R.C.B.D) with (4) replicates. Results showed that the sprays number and the concentrations of hubest (2.0 cm3 .l-1) a significant increase of all the tested characters, that led to a significant increase in leaf curl percentage, unbranched plants percentage ,and non bloomed plants percentage and plant height and early crop, and total yield. The interaction of Fore sprays with hubest 2.0 cm3 .l-1 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 (123.6سم cm, 98.27, 93.37%،, 89.92% and 92.23%)) respectively. This interaction, therefore had an obvions effect and increasing plant yield and early crop, and total yield/plastichouse (959.8g, 0.602 ton and 6.889 ton/ plastichouse) respectively as compared to control treatment. | ||
