Abstract :
The objective of these study was to investigate the effectes of plant growth promoting rizobacteria (PGPR) and humic acid applications on vegetative growth and daughter plant yields of strawberry cv. Fern. The study was carried out in Erzurum ecological conditions in 2005-2006. Completely randomized blocks were designed and arranged split plots with three replications. PGPR applications were divided into four main plots as bacteria free (B0), rot inoculation (RI), foliar aplication (FA) and RI + FA. Subplots were four humic acid (HA) doses with control such as, 2, 4, 6 and 8 L/ha. Daughter plant stem diametter (mm), length (cm), dry weight (g), fresh weight (g), leaf area of mother plant (cm^2), number of stolon per plant, number of daughter plant per stolon, stolon length (cm) and number of daughter plant per plant were investigated in the present study. In B0 main plot, 2 L/ha HA for stolon length, 4 L/ha HA for daughter plant diametter, 8 L/ha HA for daughter plant per stolon and for daughter plant per plant were found to be increase at the rate of 10.97%, 11.96%, 12.92% and 56.48%, respectively compared to control. Morever, when compared to control, RI and 8 L/da HA aplication increased length, dried weight and fresh weight of daughter plant at the rate of 11.43%, 32.29% and 28.24%, respectively. The most effective dose of HA on vegetative growth and yield of daughter plant in strawberry was 8 L/ha. It was also determined that 8 L/ha HA combined with RI gave better results than FA and RI+FA application of PGPR in the study
