Abstract:
The objective of the study was to explore possibilities to reduce fertilizer requirement and to identify bacterial strains that used for organically grown Turkish hazelnut cultivars. Plant growth promoting effects of L. enzymogenes 9/8, B. atrophaeus 55/1, A. agilis 2/3, P. macquariensis 59/8, B. lentus (Pb. validus) 29/6, B. pyrrocinia 13/4, P. agglomerans 5/8, R. radiobacter 42/1, S.s maltophilia 21/1, Acinetobacter calcoaceticus 47/6 and mineral fertilizer were tested on Turkish hazelnut cultivars (Tombul and Sivri) based on seedling length, total branch length, branch number trunk diameter and ionic composition of leaves. The results showed that all of bacterial treatments significantly affected the parameters tested. The highest seedling length, total branch length, branch number and trunk diameter of Tombul and Sivri of Turkish hazelnut cultivars was obtained with A. calcoaceticus 47/6, R. radiobacter 42/1, S. maltophilia 21/1, P.macquariensis 59/8, respectively and increasing ratio of seedling length, total branch length, branch number and trunk diameter of Turkish hazelnut cultivars was 24.49, 31.60, 69.28 and 18.74% for Tombul and 21.72, 68.43, 46.90 and 24.41% for Sivri, respectively compared to control. The concentrations of N, P, K, Ca, Mg, Fe, Cu, Mn, Zn, B and Al of plant tissue nutrients were significantly increased by the bacterial treatments tested. All bacterial treatments had positive effect but treatments 13/4 and 42/1 were the most effective in promoting macro and micro nutrient uptake. These results suggest that plant growth rhizobacteria (PGPR) treatments offer an economic and simple means to increase plant growth in soils with low fertility.
