Abstract
A study on effects of soil pH and phosphorus fertilizer on efficiency of arbuscular mycorrhizal (AM) fungi, Glomus intraradices, for hybrid field corn growing in infertile soil (Korat soil series) was conducted in 4 x 2 x 2 factorial in CRD with 4 replications. The study consisted of 3 factors. The factor 1 was soil pH (no soil pH adjustment (pH 4.37) and soil pH adjustment to 5.0, 6.0 and 7.0). The factor 2 was phosphorus (P) fertilizer (nil P and 100 % P fertilizer at recommendation rate by site specific nutrient program). The factor 3 was AM fungi (without and with AM inoculation). The corn was grown until harvesting period in sterilized soil. The results revealed that the AM inoculation can increase the growth, yield and P content of corn at all level of soil pH. Inoculation of AM fungi alone had resulted in higher growth, yield and P content of corn than 100 % P fertilizer. There was no significant difference between AM inoculation alone and AM inoculation with 100 % P fertilizer. However, the efficiency of AM fungi had decreased when applying P fertilizer at all level of soil pH. Therefore, these results indicated that soil pH did not have any effects on efficiency of AM fungi, but P fertilizer did. However, AM inoculation can be applied to corn that growing in infertile soil with all level of soil pH by without P fertilization.
