Screening of epiphytic isolates from different crops for plant growth promoting traits

The role of Zn as micronutrient in healthy growth of plants is very important. The microorganisms present in phyllospheric environment have capability to increase micronutrient availability to plants. Total forty eight isolates were obtained from five different crops (wheat, mustard, cotton, pearl millet and moong). All isolates were characterized for different plant growth promoting attributes i.e., production of ammonia, IAA, and solubilization of Zinc, Phosphate. Among all isolates total 87.5 % showed IAA and Ammonia production in different range. Total 72.91 % Zn solubalization and 60.41 % P solubalization showed by isolates respectively. These plant growth promoting attributes are helpful in enhancing crop productivity. So these can be used as bioinoculant or as spray in crops. | Screening of epiphytic isolates from different crops for plant growth promoting traits
