EFFECT OF FULZYME FERTILIZER, RICE RESIDUES AND DAP ON AVAILABLE OF SOME NUTRIENTS FOR THE SOIL OF BUDDED APRICOT SEEDLINGS PRUNUS ARMENIACA L. CV. "ZAGHINIA"

The study was conducted in the nursery of Hort. Dept., College of Agriculture and Forestry,Mosul University, Iraq, during 2018 season to study the response of budded "Zaghinia" apricot on seedlingsrootstock to bio, organic and chemical fertilizers, and their effects on seedling growth. The studied factors wereas follows: Bio fertilizer Fulzyme (0,1and 2 g. seedling-1), organic fertilizer (Rice residue) (0, 1 and 2 kg.seedling-1) and DAP fertilizers (0, 5 and 10 g. seedling-1). The study was performed by using split-split plotswithin factorial experiment in randomized complete block design (RCBD), with 3 factors and 3 replicates, byusing 6 seedlings for each treatment. Treatment means were compared by using Duncan multiple levels at 5% p.the most important results obtained were as follows: 1 and 2 gm.seedling-1 of bio fertilizer (Fulzyme) andChemical fertilizer (DAP) at the levels 5 and 10 g. seedling-1 affected significantly resulted in a significantincrease in soil available nitrogen, while the addition of organic fertilizer (rice residues) and for both levels 1and 2 kg. Seedling-1 gave a significant increase in nitrogen, phosphorus, ready-made potassium and pH of theseedling soil, and the bilateral interaction had a significant role in the growth of seedlings, especially thetreatment of the interaction between the fertilizer (Fulzym) and organic fertilizer (Rice residues), which have asignificant effect in giving the best results in available nitrogen, phosphorus and potassium in the soil, and thetriple interference also gave a significant increase in all studied traits.
