| During 2003 and 2005, plant growth promoting effects of two Bacillus strains OSU-142 (N2-fixing) and M3 (N2-fixing and phosphate solubilizing) were tested alone or in combinations on organically grown primocane fruiting raspberry (cv. Heritage) plants in terms of yield, growth, nutrient composition of leaves and variation of soil nutrient element composition in the province of Erzurum, Turkey. The results showed that Bacillus M3 treatment stimulated plant growth and resulted in significant yield increase. Inoculation of raspberry plant roots and rhizosphere with M3 and/or OSU-142 + M3, significantly increased yield (33.9% and 74.9%), cane length (13.6% and 15.0%), number of cluster per cane (25.4% and 28.7%) and number of berries per cane (25.1% and... |

| The objective of this study was to evaluate the effects of twelve plant growth-promoting rhizobacteria (PGPR; Bacillus mycoides FD07, B. sphaericus RC12, B. pumilus RC19, B. cereus RC18, Variovorax paradoxus RC21, Paenibacillus polymyxa RC35, Pseudomonas putida RC06, B. megaterium RC07, B. megaterium M-3, B. licheniformis RC08, B. subtilis RC11, and B. subtilis OSU-142) used as biofertilisers, on various enzyme activities [glucose-6-phosphate dehydrogenase (G6PD); 6-phosphogluconate dehydrogenase (6PGD); glutathione reductase (GR); and glutathione S-transferase (GST)] and on seedling growth in spinach (Spinacia oleracea L.). Enhanced plant growth could result from rhizobacterial production of indole-3-acetic acid (IAA). The highest IAA-producing... |

| N2-fixing and P-solubilizing bacteria are important in plant nutrition increasing N and P uptake by the plants, and playing a significant role as plant growth-promoting rhizobacteria (PGPR) in the biofertilization of crops. In 2007 and 2008, a field study was conducted in two different locations (Erzurum and Ispir) in the Eastern part of Turkey for investigating the effects of two N2-fixing and P-solubilizing PGPR strains alone and in combinations on plant yield and nutrient content of wheat in comparison to control and optimum and half doses of N fertilizer application under field condition. All inoculations and fertilizer applications significantly increased grain, total biomass yields, and macro and micro nutrients of wheat over the control. Mixed PGPR... |

| Dünyada tarımsal üretimin yoğun olarak yapıldığı ülke veya bölgelerde sentetik gübre ve kimyasalların aşırı kullanımı insan ve çevre sağlığını tehdit ettiği çok sayıda bilimsel araştırmalar ile ortaya konulmuştur. Bu nedenle aşırı sentetik gübre ve kimyasalların tarımsal üretimde kullanılmasının insan sağlığı ve ekolojik denge üzerindeki olumsuz yan etkilerini azaltmak veya tamamen ortadan kaldırmak için yeni ve alternatif tarımsal üretim sistemleri geliştirilmiştir. Tarımsal üretimde sentetik girdileri azaltan sürdürülebilir tarım veya reddeden (mümkünse) organik tarım stratejileri önem kazanmıştır. Organik tarım daha çok dogal girdilerin kullanılması önerilmektedir. Bitkisel üretimde verim ve kaliteyi tehtid eden sorunların (beslenme ve koruma) çözümünde... |
