Abstract EN
The Persian walnut (Juglans regia L.) is one of the important horticultural crops grown in Kurdistan region of Iraq.
This research was conducted to determine the effect of humic acid and bio horme on some growth characteristics of walnut seedling.
During spring season (growth stage) of 2013.
The study was done on the seedlings walnut (Juglans regia L.).
The age of treated seedlings was one year cultivated in black plastic bags filled with sandy loem soil.
The treatments of experiment included concentrations of humic acid )0, 2 ,4)ml.l-1 and bio horm (0 , 3 , 6) ml.l-1, each treatment was applied three times at 20/4, 5/5, 20/5 /2013.
A complete randomized block design (R.C.B.D) with three replicates each consisted of 4 seedlings was used to carry out this research.
Data collected at the end of September 2013 indicated that, foliar spray of Humic acid at 4 ml,l-1 resulted in a significant increase in Shoot numbers, number of leaves , shoot diameter, shoot dry weight (gm), Root numbers and Leaf area(cm2) as compared with control treatment.
Mean while spray of Bio horm at 6 ml.l-1.
led to the most significant increase in shoot numbers, number of leaves, shoot diameter (mm), shoot length (cm), shoot dry weights (gm), root numbers, root length, root dry weights (gm) and leaf area (cm2).
At the same time, application of Bio horm at 3 ml.l-1.
gave the highest increase in percentage chlorophyll pigment as compared with control treatment.
