The Effect of Inoculation With Amycolatopsis Strains On Yield and Nutrient Content of Wheat (Triticum Aestivum L.) and Soil Microbiological Properties
Abstract In this study, the yield and nutrient content of wheat (Triticum aestivum L.) grown in greenhouse conditions and soil microbiological properties were investigated. Inoculating Amycolatopsis strains, including A.magusensis DSM 45510T, A.orientalis DSM 40040T, and A.azurea DSM 43854T was considered. The mixture of wheat straw (WS) was used to increase soil organic matter content by 5%. It was determined that the grain and straw yield of wheat increased significantly (P < 0.001) in inoculation with Amycolatopsis strains in soils without WS. However, inoculation with Amycolatopsis strains in soil with WS significantly decreased grain and straw of wheat yield. Also, it was found that soil microbial biomass and soil basal respiration (SBR) increased in inoculation with Amycolatopsis strains in both soils with and without WS. While it was established that Cmic:Corg ratio of the control group in the soil samples at the end of the harvest was 1.23, infusing with Amycolatopsis strains was observed to be around 2.95–3.31. Moreover, inoculation with Amycolatopsis strains in soils with WS varied between 0.32–0.40. In the same way, it was determined the microbial metabolic quotient (qCO2) was 2.58 in the control group. This meaning was between 5.67–5.82 in infusing with Amycolatopsis strains and 6.04–6.41 in inoculating with Amycolatopsis strains in soils mixed with ground wheat stalk. As a result, it suggested that the yield of wheat could be increased inoculation with A.magusensis, A.orientalis, and A.azurea, from Amycolatopsis strains, in soils with low soil organic matter content and soils that cannot be shown an increment in terms of organic matter content.
