Abstract
Drawbacks of intensive farming practices and environmental costs of N fertilizers have renewed interest in bio-fertilizers. This study was conducted in order to investigate the effectiveness of 7 N2-fixing bacterial isolates from various sources in sugar beet and barley production under field conditions in the higland plateau of Erzurum, Turkey (29° 55′ N and 41° 16′ E with an altitude of 1950 m) in 1999 and 2000. Seeds were inoculated with five bacterial strains of Bacillus; BA-140, BA-142, M-3, M-13, and M-58, a strain of Burkholderia (BA-7) and Pseudomonas (BA-8). The bacterial strains had been demonstrated to grow in N-free basal medium. The experiment also included applications of mineral nitrogen (N), phosphorous (P), and NP-fertilizer as well as a control treatment without inoculation and fertilizer application. Two years of trials under field conditions showed that seed inoculation with bacterial strains significantly affected yield, yield components, and quality parameters both in sugar beet and barley. On an average of both years, seed inoculation of sugar beet with BA-140, BA-142, M-58, BA-7, BA-8, M-13, and M-3 increased root yield by 13.0, 12.6, 10.5, 9.2, 8.1, 6.1, and 6.5% as compared to the control and sugar yield by 7.8, 6.3, 5.1, 4.0, 3.2, 2.3, and 5.3%, respectively. N, P, and NP applications, however, increased root yield up to 13.6, 5.3, and 21.4% and sugar yield by 6.1, 4.0, and 14.8%, respectively. Of the bacteria tested, BA-140 and BA-142 had yields equal to N application. All bacterial inoculations also gave higher seed and total biomass yields in barley than control plots. BA-140 and BA-142 were top yielding strains. In conclusion, bacterial seed inoculations especially with BA-140 and BA-142 may satisfy nitrogen requirements of sugar beet and barley under field conditions even in upland areas.
