Project Number: 8070-13000-012-34-R
Project Type: Reimbursable Cooperative Agreement

The goal of this project is to determine N use efficiency of N-Fix inoculated plants under field conditions.
Select grasses, inoculated and uninoculated, will be planted and grown in a complete block design and fertilized at 0, 25%, 50%, 75% and 100% of the recommended N rate. Field colonization will be assessed by DNA extraction, PCR amplification, and comparison with a positive control derived from previously sequenced G. diazotrophicus culture. Leaf chlorophyll will be measured using a commercially available chlorophyll meter. Plots will be harvested for biomass production and plant tissue analysis to determine the degree to which inoculation results in improved N use efficiency.
