Research carried out in plastic house of the Department of Horticulture - Collage of Agriculture - University of Kirkuk during the growing season (2014-2015) to study the effect of IBA, Humic Acid and seaweed extract Kelpak on shoot and root growth of the cutting of peach (prunus persica L.) va. Nimagard.
The study included treatment for the two concentrations IBA (0 , 4000) mg.l -1 and spraying with Humic Acid three concentrations (0 , 2 and 4) ml.l -1 and spraying sea weed extract Kelpak three concentrations (0 , 2 and 4) ml.l -1 and the impact of interference between the studied factors in the growth characteristics studied.
And carried out the experiment design randomized complete sectors (RCBD) the experience of three global factors and three replications, and analyzed the results of the experiment were selected statistically using Multinomial Duncan test at the level of 5% probability.
The following are the most important findings of the study:
1. led treatment with IBA to a significant increase in characteristics shoot growth (the length of shoots and number of shoots and number of leaves and area of leafy and chlorophyll and dry weight of shoot) as well as increased significantly in (the percentage of nitrogen)and led spraying with Humic Acid to a significant increase in characteristics shoot growth (the length of shoots and number of shoots and number of leaves and area of leafy and chlorophyll and dry weight of shoot) and also influenced significantly in (the percentage of nitrogen) and spray extract sea Kelpak led to a significant increase in characteristics shoot growth (the length of shoots and number of leaves and area of leafy and chlorophyll and dry weight of shoot). While not significantly affect the number of shoots and the percentage of nitrogen.
2. Led of bilateral interactions of the factors studied significant effect evident in most of the qualities of growth and Showed the results of the tripartite interactions between IBA and Humic Acid and sea algae extract Kelpak significant effect in most characteristics shoot growth and nutrient concentrations.
