Author : Ayad Hani Alalaf and Nameer Najib Fadel

The study was conducted in the lath house of the Department of Horticulture and Landscape Design /College of Agriculture and Forestry, University of Mosul, to demonstrate the effect of two spring budding dates (April 2 and 17) with the local orange Citrus sinensis L. seedlings on Citrus Aurantium L. seedlings and the addition of chemical fertilizer (NPK) at two levels (0 and 30). Seedlings-1 gm) and biological and organic fertilization at seven levels, including liquid organic (Neutrgreen) at a level of (6 ml.l-1) and biofertilizers (Biogen at levels 3 and 6 gm Anvil-1 and Potassium Mag at levels 5 and 10 gm. Anvil-1 and Folzyme at one level ( 1gm. Anvil -1)) On the success rate of budding and subsequent growth of grafted seedlings, the study was carried out using a split-plate system within a randomized complete block design (RCBD) for factorial experiments with three factors, and the average coefficients were compared using the Duncan multinomial test at a 5% error probability level. The most important results obtained can be summarized as follows: The first appointment on April 2 was significantly superior to the second appointment on April 17 in the two characteristics (length of developing shoots, fresh weight of leaves, and percentage of carbohydrates in leaves), while there were no significant differences between Chemical fertilizer levels with the studied traits. On the other hand, the levels of biological fertilizers (potassium and Biogen) achieved significant superiority in all the studied traits compared to the comparison treatment.
