Oilseed Meal Effects on the Emergence and Survival of Crop and Weed Species

Table 3

Three-way interaction of “seed meal source, application rate (applic) and incubation time (incub)” on johnsongrass and pigweed emergence (emerg) and survival (surv). Incubation refers to the length of time in days after SM was added to soil and prior to seeding. Data are the means (four replications) within weed species (𝑛=144).
