Effect of soil treatment and experimental repetition on the final abundance of reniform nematode (Rotylenchulus reniformis) in soil and storage root weight of sweetpotato planted into potted field soil from the LSU AgCenter Macon Ridge Research Station. Soil treatments sharing the same letter within a column do not differ significantly (P > 0.05), according to Tukey's HSD test.
