Sampling for Plant-parasitic Nematodes in Corn Strip Trials Comparing Nematode Management Products

Fig. 6. Layout of a strip trial with 12-row (30-ft-wide) strips of three treatments (A, B, and C) repeated several times, planted with a 24-row planter. Treatment C would be in the left 6 units, treatment B in the center 12 units, and treatment A in the right 6 units of the planter. The arrangement of treatments shown in the diagram is created when the tractor follows a back-and-forth or serpentine pattern to plant the field, starting in the lower left corner of the field. Areas in white depict border rows of treated seed that would not be used for data collection. Sampling areas or “plots” are created in the strips by designating 12-row-wide by 30-ft-long areas for sampling. Ideally, yield data could also be obtained from the sampling areas or “plots.”
