Activity of microbiota in the rhizosphere of lentil under the influence of biological preparations
Journal Title: «Таврійський науковий вісник» - Year 2018, Vol 103, Issue
Abstract
Current conditions of production lead to the violation of the balance among different groups of microbiota. As a result, there is a necessity to use agricultural measures aimed at increasing agronomically valuable microorganisms in rhizosphere. Application of microbial preparations opens a prospect of their extensive introduction in agriculture, allows decreasing the amount of mineral fertilizers, the production of which requires a substantial energy use. The aim of our research is to determine the influence of gel form of microbial preparation Rhizobium leguminosarum Lens, strain K-29 and plant growth regulator Regoplant on the number of microbiota and its activity in the rhizosphere of lentil. Vegetation experiments were carried out in a four-time replication according to the vegetation method described by Z.I. Zhurbytskyi. The results of the research have shown that the integrated application of PPP Regoplant and microbial preparation Rhizobium legominosarum Lens strain K-29 stimulates the microbiological activity of rhizosphere in lentil plantings as well as enzyme activity. The highest indexes of the number of lentil rhizosphere bacteria formed in the variants with the application of plant growth regulator Regoplant 50 ml/ha applied at the background of pre-sowing treatment of seed with microbiological preparation Rhizobium leguminosarum Lens strain К-29 2 l/t together with Regoplant 250 ml/t. This exceeded control by 61%, micromycete by 52% and actinomycete by 48% with a simultaneous increase in enzyme activity by 48%, 29 % and 66 % for invertase, catalase and protease, respectively
