Two graphs with color coding showing turfgrass quality in the first graph and the plot randomization in the second graph.

Thanks to NTEP-DB 1.0 [1], the relational database we created for the National Turfgrass Evaluation Program (NTEP), obtaining turfgrass cultivars' data will soon be much easier.
