Özet

5Fig tree mainly spread in regions where Mediterranean climate prevails can be grown over a wide range of soils without any significant deficiency or toxicity symptoms of plant nutrients. Surveys revealed that, however, quality is highly affected by nutrition especially N, K and Ca in fig production for commercial drying. This research work was initiated based on few studies performed on fertilization of fig. The experiment was performed between 2000 and 2002 in three fig orchards of cv. Sarilop (syn. Calimyrna) in Aydin-Turkey. Trees received seven types of fertilization as (i) untreated control; (ii) NPK (430 g N, 200 g P2O5 and 430 g K2O per tree): (iii) NPK + 70 g Ca; (iv) NPK + 140 g Ca; (v) NPK + 280 g Ca: (vi) NPK + 420 g Ca and (vii) N + 420 g Ca, Ca(NO3)(2) used as the Ca source. Tested fertilizer applications showed significant differences in respect to yield and quality of fig. Basic NPK fertilization with additional 280 g Ca treatment increased overall quality by reducing the number of fruit with ostiole-end crack and sunscald. Results showed that applied fertilizers exerted significantly in reduction of cull ratio and could alleviate the negative impact of yearly drought conditions. (C) 2008 Elsevier B.V.
