Exploring plant growth-promoting

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 enhanced range traits including grain in glasshouse (13–23%) (9–12%) over control. In experiments an stover concentrations were observed ICMH-1201 (Fe 53% 40%; Zn 15% 10%; Ca 11% 29%) control, while such nutrition augmentations not found PA-9444. harvested also increased control both hybrids. A higher concentration was PA-9444 had increase indicating significance these strains’ PGP role hybrid. Based on this study, KAI-27 MMA-32 improved shoot weight, root weight CAI-24 Fe contents (up 49%) as well stover. Further, samples contained (150–200%) compared samples. This confirms that have potential enhancing can complement existing conventional biofortification strategies.
