Evaluation of the effects of triple PGPR isolates and biological fertilizer formulations formed with different containers on growth and development parameters in Pazar-20 tea clone

This study was established with two-years-old tea seedlings in the Pazar-20 clone pots and eight applications as five different biological fertilizers, triple bacteria combinations (F1, F2, F3, F4 and, F5), one fertilizer, NPK fertilization (1400 mg compound 25:5:10/seedling) control (fertilizer not applied) applications, seven carriers liquid six solid. It four replications each replication according to factorial arrangement (8 x 7 carriers) carriers. For preliminary evaluations, only plant height, stem diameter number of leaves were evaluated without cutting seedlings. In experiment, at end November 2013, 2014, harvested from equal branch+leaf weight, fresh dry leaf yield, chlorophyll content (SPAD value), area results evaluated. Depending on bacterial inoculations, fertilizer used, inoculated formulations, significantly affected diameter, number, According carrier averages, mineral fertilization, F1, F5, which caused a significant increase leaves, compared control, same group. All selected increased weight increasing rates statistically (p≤0.05). average application, gave most relevant result terms measured parameters, followed by solid leonardite, compost, peat-based carriers, respectively.
