Soybean Cyst Nematode Study

MATERIALS AND METHODS

S14-J7, an SCN susceptible cultivar, and S17-B3, a resistant cultivar to SCN, were used in a split-plot arrangement in RCBD at both Hurley and Southeast Farm. Early and late stand counts were carried out at V5 and R8, respectively. Yield, test weight, protein and oil contents data sets were also collected. Multiple comparison of treatment means (LS-means) were reported using the least significant difference (LSD).

RESULTS AND DISCUSSION

SCN Study SERF:

Similarly, there were no differences due to treatment effects for both stand counts, yield and test weight (Table 1 and Table 2). The only significant differences at SERF were observed in protein and oil contents and these differences were due to cultivar effect. Significant cultivar and treatment effects were observed for fall SCN counts which indicated that treatment 3 (Avicta Complete Beans 500 + Vibrance) and treatment 5 (CruiserMaxx Vibrance Clariva PN + Mertect) were different from the rest of the treatments yet not significantly different from each other. The highest increase in soil SCN occurred in plots treated with the two chemicals. No significant associations were observed among yield, late stand counts and fall SCN counts.
