| Abstract | ||
| This research was conducted at the Agricultural Research and Experiment Station of the College of Agriculture / University of Kirkuk, during spring season 2019 to study the effect of humic acid and sea force and NPK on some growth characteristics of blackberry (Morus nigra L.). The treatments of experiment included concentrations of humic acid(0,5,10) g.l-1 and sea force (0,1.5,3) ml.l-1 and NPK(0,1,2) g.l-1 each treatment was applied 3 times. the experiment was carried out according to the randomized complete block design(R.C.B.D) with (3) replicates each consisted of (1) tree was used to carry out this research. indicated that foliar spray of Sea force at 3 ml.l-1 resulted in a significant increase in leaf area (88.366 cm2) length of branches (244.286 cm),chlorophyll (21.901CCI) and leaf dry weight(51.742%) as compared with control treatment. Mean while spray of NPK at 2 g.l-1. led to significant increase in leaf area (80.801cm2), length of branches (39.658cm) chlorophyll (19.915 CCI ) and leaf dry weight (45.462%) as compared with control treatment. At the same time application of (sea force at 3ml.l-1 +NPK 2g.l-1) gave the significant increases in leaf area (89.853cm2), length of branches (45.060cm), chlorophyll(22.300 CCI) and leaf dry weight(52.400%) as compared with control treatment. | ||
