EFFECT OF MEZORHIZOBIUM CICERY STRAIN AND CHLORMEQUAT CHLORIDE ON MORPHOGENESIS AND PRODUCTIVITY OF CHICKPEA PLANTS

Abstract

The effect of strain Mezorhyzobium cicery MS 285 and that of the strain combined with preparation of the quaternary ammonium class retardant -chlormequat chloride on the culture of Triumph chickpea were studied in the field experiment. The positive effect of the strain Mezorhyzobium cicery in complex with synthetic growth inhibitor chlormequat chloride (used in the budding phase of the culture) on the morphometric parameters and crop capacity of Cicer arietinum was established. It was found that both the strain and the retardant against inoculation background of Mezorhyzobium cicery led to a change in the habitus of experimental plants. There was also observed increase of total leaf area in the conditioned plants on account of the additional leaf shooting that enabled more essential donor sphere formation. This enhanced better crop capacity of the plants and positively influenced the yield. At the end of vegetation there was ndicated an increase of nitrogen and potassium contents in the seeds under the effect of both the strain of Mezorhyzobium cicery and the integrated use of the preparations. There was a simultaneous decrease in the amount of sugars in the variants with growth regulators ( the strain of Mezorhyzobium cicery MC 285 ; the strain of Mezorhyzobium cicery MC 285 + chlormequat chloride). The most productive option proved to be in the variant with integrated application of the strain and retardant.
