Abstract

Plants require essential elements like C, H, O, N, P, K, considered as a macro elements and Zn as a micro element. This elemental approach can be done either by naturally or organic/inorganic fertilizers, conventionally. Considering the sustainable approach towards plant growth and development, usage of organic and inorganic fertilizers reduced by using biofertilizer with mineral weathering efficiency. Such a strain belong to family Actinomycetes, Streptomyces nanhaiensis strain YM4 was isolated from rhizosphere of rajagra plant of Khambhat region helps to plant growth promotion and mineral solubilisation efficiency. Present report suggest that it produces 73 µg ml-1 of indolic compounds and 4.48 µmol ml-1 ammonia production. Along with that it has an efficiency to solubilize 232 mg ml-1 of phosphate, 41.6 mg ml-1 of potassium and 41.16 ppm of zinc in laboratory conditions. The pot trial of liquid bioformulation of strain YM4 on millet crop enhance the plant growth with enhanced leaf biomass and pigment production, significantly. Effect of strain helps to mineralize and accumulate minerals in rhizospheric region of the millet crop.
