| Abstract | ||
| The study was conducted during 2012 seasone in lath house / Horticulture and Landscape Design Dept. / College of Agriculture & Forestry / Mosule University. Loquate seedlings (25 – 27 cm height and its main stem diameter above 10 cm from the soil were 4.9 – 5.25 mm) which were planted in polyethelene bags (7 kg capacity from Loamy soil) were selected from the nursery of Hortic. & Landscape Design Dept., to study the effect of four Liquid organic fertilizers (Humic acid, Org, Nutergreen and Vetamenol plus) by using two concentrations of each fertilizer (1 and 2 ml . L.-1) , in addition to control treatment on some vegetative growth parameters of the seedlings . Randomized Completely Blocked Design (RCBD) Design were used in this study with five seedling for each experimental unit . The organic fertilizers were added twice per /aseason, at 9 / March / 2012 and second was at 9 / April / 2012 and 100 ml from each concentration were applide at each application. Results indicated that leaves chlorophyll and all vegetative growth parameters significantly increased by the application of liquid organic fertilizers, especially with 2 ml. L.-1 concentration the souree Org. fertilizer gave the highest mean of leave chlorophyll (61.55 SPAD unit), main stem diameter (2.21mm) and leaf fresh weight (7.43gm), Application of Nutergreen fertilizer at 2 ml. L-1 gave the highest NO. of seedling leaf seedling -1 (10.66 leaves), leaf area (64.33 cm2), seedling leaf area (3629.7 cm2 / seedling) and leaf dry weight (3.21gm / leaf). therefore we can concluded that under the experiment conditions org and Nutergreen organic fertilizers gave the best results. | ||
