The Influence of Fertilization upon the Powdered Mildew (Microsphaera Abbreviata) Attack Degree in Durmast Seedlings
Abstract
Concerning the management of durmast seedlings cultures in nurseries, the main methodology applied for enhancing their development and resistance against diseases, relies on the following issues: irrigation, high biological value seedlings, mechanization, disease fight specific chemicals, and, at last but not at least, an appropriate fertilization. The aim of this paper is to identify of the most efficient fertilizing option, in order to form an important variable for increasing the resistance to the powdery mildew attack. The trial was carried on during experimental year 2009 in a durmast nursery from Transylvanian Plain. During vegetation period, the attack degree of Microsphaera abbreviate was recorded. A monofactorial design was put into practice, using 3 variants. Basic statistic and correlations were calculated using STATISTICA v. 7.0. The biggest attach degree of Microsphaera abbreviata on durmast seedlings was recorded in the variant where fertilization was performed with maximum mineral fertilizer dose, N80P80K80 (6.31%), respectively, followed by attack degrees recorded for other mineral fertilizer doses N60P60K60 (5.54%) and N40P40 is classified on the 5th place. Our trial shows that N80P80K80 with poultry manure is the fertilization solution, which confers to durmast seedlings the biggest resistance against the attack degree of Microsphaera abbreviata mushroom.
