Abstract

Six mycorrhizal fungi were tested as inoculants for pearl millet (Pennisetum americanum) grown in pots in a greenhouse. VAM fungi varied in their ability to stimulate plant growth and phosphorus uptake. Inoculation with Gigaspora margarita, G. calospora and Glomus fasciculatum increased shoot dry matter 1.3-fold over the uninoculated control. In another pot trial, inoculation with Gigaspora calospora and Glomus fasciculatum resulted in dry matter yields and phosphorus uptake equivalent to those produced by adding phosphorus at 8 kg/ha. The influence of inoculating Gigaspora calospora on pearl millet at different levels of phosphorus fertilizer (0 to 60 kg P/ha) as triple superphosphate in sterile and unsterile alfisol soil was studied. In sterile soil, mycorrhizal inoculation increased dry matter and phosphorus uptake at application levels less than 20 kg/ha. At higher P levels the mycorrhizal effect was decreased. There was no effect of mycorrhizal inoculation in unsterile soil
