Technical Abstract: Efforts to reduce fertilizer rates while increasing nutrient uptake to maintain high yields are very important due to the increasing cost of fertilizers and their potential negative environmental impacts. The objectives of this study were to determine (i) if reduced rates of inorganic fertilizer coupled with microbial inoculants plant growth-promoting rhizobacteria with and without arbuscular mycorrhizae fungi (AMF) will produce plant growth, yield, and nutrient uptake equivalent to that obtained with full rates of the fertilizer and (ii) what minimum level the fertilizer could be safely reduced. We used a two-strain mixture of Bacillus amyloliquefaciens IN937a and Bacillus pumilus T4 as well as a formulated rhizobacterial product and an AMF, Glomus intraradices, in the greenhouse. Results showed that supplementing 75% fertilizer with inoculants produced plant growth, yield, and nutrient (nitrogen and phosphorus) uptake that were statistically equivalent to full fertilizer rates. Lower fertilizer rates supplemented with inoculants produced significantly lower plant growth, yield, and nutrient uptake or inconsistent impacts. Further studies using isotope techniques that will reveal specifics on the interactions and impacts of the inoculants and plant uptake of nitrogen are planned.
