Influence of biopreparation ‘Zamin-M’ on cotton plants (gossypium hirsutum) under soil salinization in Uzbekistan

Abstract In this article, a microbial inoculant acting as a biofertilizer is considered as a biostimulant, consisting of three strains of local salt-tolerant strains of rhizobacteria Pseudomonas stutzeri SKB308, Bacillus subtilis SKB309, Bacillus megaterium SKB310. The authors have developed and introduced into agricultural practice an experimental sample of the biological product ‘Zamin-M’, which increases the resistance of cotton to stress conditions of soil salinity. It is proved that the biological product ‘Zamin-M’ increases soil fertility has a beneficial effect on the enzymatic activity of the soil and the development of a population of beneficial microorganisms. The bioproduct ‘Zamin-M’ is presented as a new stimulant in the practice of growing cotton in saline conditions. An agricultural technique for the use of a local biological product in agriculture has been developed. The ‘Zamin-M’ is included by the State Committee of the Republic of Uzbekistan in the list of agrochemicals and pesticides permitted for use in agriculture of the Republic of Uzbekistan (certificate No. 1A1005).
