Plant Growth Promoting And Organic Waste Degrading Activities Of A Native Rhizobacterial Strain Of Alcaligenes faecalis For Wheat Cultivation

摘要

A native isolate of rhizospheric Alcaligenes faecalis was isolated from agricultural soil of peri urban area of Lucknow and characterized by morphological and molecular characteristic using 16s RNA. It showed in-vitro, plant growth promoting activities by producing indole 3-acetic acid (IAA), hydrogen cyanide, siderophore, ammonia and showed phosphate solubilization activities potential. An earthen pot experiment was conducted under net house conditions with the isolated strain (1x10~8 CFU/mL) which increased root length (28, 33 and 67%), shoot length (30, 45 and 55%), fresh weight (54, 67 and 90%), dry weight (55, 77 and 55%), number of root hairs (92, 69 and 38%), number of leaves (46, 63 and 58%) at an interval of 40, 80 and 120 days after sowing (DAS) in wheat (Triticum aestivum PBW 343). The weight grain per plant was also increased by 68% over control.
