Abstract
Microbiological fertilizers are an important part of environment friendly sustainable agricultural practices. A study was conducted in order to investigate seed inoculation of sugar beet (cv. Sonja) and barley (cv. Tokak), with nitrogen fixing (Bacillus polymyxa) and phosphate dissolving (Bacillus megaterium var. phosphaticum) bacteria in comparison to control and mineral fertilizer application in the green house and in the field at two sites in 1996 and 1997 in Erzurum (29o 55' N and 41o 16' E with an altitude of 1950 m), Turkey. In the green house trial bacterial inoculation of seeds increased sugar beet root and barley seed yields compared with control. B. polymyxa was more effective, but dual inoculations gave increases of 19.0 and 25.9% respectively. In the field as an average of sites and years sugar beet root yields were increased by 12.0%, 7.5% and 16.5% while barley seed yields were increased by 15.0%, 8.4% and 18.2% respectively with B. polymyxa, B. megaterium var. phosphaticum and dual applications over control treatment. Other yield and yield components were also enhanced especially by dual applications. However, increases in yield and yield components were lower than or comparable to mineral fertilizer application. The beneficial effect of bacterial inoculation was higher in well irrigated pot trials and at the site of rich clayey soils. In conclusion, microbial inoculation of seeds with Bacillus polymyxa and B. megaterium var. phosphaticum, alone or in dual combinations, may substitute costly NP fertilizers in sugar beet and barley production even in cold highland areas such as in Erzurum.
