Root colonization and spore population of AM fungi in cultivated crops

Abstract

Microorganisms have been extensively used in supplementing the nutrient demand of the crop, thereby reducing dependence on chemical fertilizers. Rhizospheric microorganisms maintain a close relationship with plants and help stimulate plant growth. Arbuscular mycorrhizal fungi are ubiquitous and improve mineral nutrient uptake and enhance abiotic stress tolerance. Glomus fasciculatum, G. macrocarpum, G. etunicatum, G. mosseae, G. constrictum were recovered from the roots of almost all the plants in present study. G. fasciculatum was the dominant one. The percent colonization occurred to the maximum extent with tomato crop at all the sites. Spore population of AM fungi was found highest in case of tomato and lowest for okra plants.

Evaluation of arbuscular mycorrhizal fungi in cultivated crops

“…Temperature as well as rainfall ranges between 44 o C to 14 o C and 65 to 75 cms, respectively throughout the year. The soil of the district is mainly sandy loam (Khan 2023). The pH ranges between 6.7 to 8.3 and good irrigational facilities with a significant soil moisture between 4.05 to 8.90%.…”
