The present study aimed to demonstrate the use of two strains Streptomyces albus (CAI-24 and KAI-27) one strain S. griseus (MMA-32) for plant growth-promotion (PGP) improving pearl millet yield nutrient content under greenhouse field conditions. Two hybrids, a low-Fe (PA-9444; non-biofortified hybrid) high-Fe (ICMH-1201; biofortified hybrid), treated with selected strains, significantly enhance...
