During 2003 and 2005, plant growth promoting effects of Pseudomonas BA-8 and Bacillus OSU-142 were tested alone or combinations on sweet cherry (Prunus avium L.) cv. 0900 Ziraat in terms of yield, growth, nutrient composition of leaves in the province of Konya, Turkey. The presence of Pseudomonas BA-8, Bacillus OSU-142 and BA-8 + OSU-142 stimulated plant growth and resulted in significant yield increase. Floral and foliar applications of BA-8, OSU-142 and BA-8 + OSU-142 in sweet cherry significantly increased yield per trunk cross-sectional area (16.3, 10.9 and 21.7%), fruit weight (4.15, 5.37 and 1.24%) and shoot length (11.3, 11.8 and 29.6%), respectively, compared with the control. In addition, N, P and K contents of sweet cherry leaves with BA-8, OSU-142 and BA-8 + OSU-142 treatments, Fe and Zn contents of leaves with BA-8 + OSU-142 treatment and Mn content of the leaves of sweet cherry with BA-8 and OSU-142 applications significantly increased. Nitrogen, P and K contents in leaves were determined to be increased from 2.00, 0.17 and 0.43% in the control to 2.19, 0.20 and 0.54% by BA-8 application, to 2.32, 0.24 and 0.54% by OSU-142 application and to 2.43, 0.22 and 0.51% by BA-8 + OSU-142 application, respectively. Co-inoculation of BA-8 + OSU-142 increased Fe and Zn contents of leaves up to 50.5 and 35.5% compared with the control, respectively. Manganese content of leaves significantly also increased by BA-8 (26.6%) and OSU-142 (27.0%) applications compared with the control. The results of the present study suggested that Pseudomonas BA-8 and Bacillus OSU-142 alone or in combination have a great potential to increase the yield, growth and nutrition of sweet cherry plant. © 2006 Elsevier B.V.

Effects of Rhizobacteria on the Nutritional Status of Blackberry Cultivars Grown in Calcareous Soil Conditions

Limestone soils, which possess restricted solubility of microelements such as iron, manganese, zinc, and copper, cover 30% of the earth’s land surface. Chlorosis is a devastating disease that can drastically reduce agricultural yields. As a result, the farmer must use more expensive fertilizer to resolve the problem, increasing the cost of producing the crop. In the present study, it was found that treatment T8 (T8:637Ca+SY48+SY55) was found to be more effective in terms of nutrient supply to the plants in both blackberry cultivars. The nitrogen, phosphorous, and iron content (2.14–4.03%, 0.40% and 125.54 mg kg−1) were found to be highest in ‘Chester’ as compared to cultivar ‘Jumbo’ (1.93–3.62%, 0.37% and 112.90 mg kg−1), respectively. Copper content varied between 6.42 mg kg−1 and 14.55 mg kg−1 in the ‘Chester’, while it varied from 5.77 mg kg−1 to 13.09 mg kg−1 in the ‘Jumbo’ cultivar. The positive effects of rhizobacteria have been the subject of research, especially in arid, saline, and partially calcareous soils. According to the results of this research, it has been seen that positive results will be obtained from the use of bacteria with different abilities in nutrition together.
