Farklı mikrobiyal gübrelerin boysenberry çeliklerinin köklenmesi üzerine olan etkileri

Blackberry is a kind of fruit that can be evaluated in different ways and important for human health because of antioxidants and pigments content. Synthetic hormones are generally used for rooting in commercial blackberry cultivation and it is important to investigate alternative preparations that can be used in organic farming. This study was carried out in the greenhouse where a mist propagation and suitable conditions for rooting were provided, to investigate the effect of different microbial fertilizers on rooting of boysenberry cuttings. The experiment was established in randomized plots experimental design with 4 replications. In the study, cuttings of boysenberry ( Rubus loganbaccus× Rubus baileyanus Britt) were used as plant material. In the study, control application and 3 different doses of preparations named SimBacil (2%, 4%, 8%), SimDerma (5 g, 10 g, 20 g), OrgaStar (2%, 4%, 8%), obtained from commercial companies were used. Number of leaves, stem diameter and length of the cuttings were recorded weekly, root number, root length and root weight measurements were determined at the end of the experiment. At the end of the study, it was determined that microbial fertilizers had a significant effect on the rooting of blackberry cuttings compared to control application. As a result, the highest average root length determined in 8% SimBacil (19.47 cm), root weight was determined in 4% OrgaStar (18.42 g) and root number was determined in 20 g SimDerma (16.00 number/plant) application. As a result, it is suggested that organic certified fertilizers can be used in rooting blackberry cuttings.
