Abstract
Abstract: This experiment was conducted in the Lathhous of the Technical Instituite Musaib during 2010 growth season to find out the impact of urea (0, 2 , 4 , 6 gm L ) and GA3 ( 0 , 50 , 100 and 150 mg L ) on growth of sour orang seedlings in an CRD experiment with 3 replicates The experiment factors and their interaction had a noted influence on growth of the seedling. The treatment of urea with 6gmL gave the highest seedling high and did not differ significantly with the concentration 4 gm L in the circumference and the shoot number. This conc. Resulted in higher means of leaf number and leaf area. The GA3 with 100 mg L , on the other hand , gane the best results in all characters studied. The combination of 4 gm L with 100 mg L GA3 gave highest means of plant hight ,circumferoince , shoot number , leaf number and leaf area that are 71.33 cm ,0.89 cm,7.44 shoot ,72 leaf , 2325.45 cm2 respectively.
