| Abstract | ||
| This study was conducted in Az-Zubiar city –Basrah governorate between 232006 to 152007 to study the effect of injection by IBA (Indole Butryric Acid (and adding NPK fertilizer which equal (20:20:20) , high N (52:20:20),high P(20:52:20) or high K in rooting and some of root and vegetative system characteristics of aerial date palm offshoots cv.Hillawi and the results showed: 1. The root system: 1.1: Number of roots: the results showed the significant superior of injection treatment alone and with adding NPK fertilizer with different concentrations on control treatment which the higher average of formatted roots appeared in injection and adding NPK fertilizer as high P which (11.75) while in control treatment (3.5). 1.2: Roots length (cm): the results showed treated with injection and adding NPK as equal or high N superior significantly on other treatments while lowest average of root length recorded in control treatment with significantly difference of other treatments also do not notice a significant difference between injection treatment alone and with adding NPK fertilizer as high P or K. 1.3. Root diameter: the results showed a higher root diameter was appeared in injection and adding equal NPK fertilizer which (8.4) while a lowest root diameter recorded in control treatment which (5.29). 1.4: Dry matter (%): the highest value of dry matter was recorded in injection and adding equal or high N or P NPK fertilizer treatments with significant difference of other treatments while a lowest value recorded in control treatment with significant difference also do not notice a significant difference between injection alone and adding NPK fertilizer as high K. 2. Vegetative system. 2.1: Number of leaves: the results showed the lowest average of leaves number was in control treatment which (0.67) while do not record any significant difference between the injection alone and adding NPK fertilizer equal, high N or high P and these treatments superior of injection and adding NPK as high K. 2.2:leaf length: the highest length of leaf recorded in injection and adding equal NPK fertilizer with significant difference of other treatments but without significant difference of injection and adding NPK as high K which (50.91 and 48.25) cm. respectively, while lowest length of leaf recorded in control treatment with significant difference of other treatments which (29.39)cm. 2.3: Dry matter(%):the results showed the significant superior of injection and adding NPK fertilizer as equal or high N of other treatments and the injection and adding NPK as high P or K treatment was superior significantly of injection alone and control treatment and injection alone superior of control treatment. 2.4: Carbohydrate (%): the highest average of carbohydrate recorded in injection and adding NPK fertilizer as high P which (27.66%) with significant difference of other treatments but without significant difference of adding equal NPK difference while the lowest value in control treatment which (19.14%) with significant difference of other treatments. | ||
