Interpretive Summary:

Technical Abstract: An experiment was established in 1994 to investigate the effects of no-till and conventional tillage production systems on the population development of Heterodera glycines. Soybean, either resistant or susceptible to H. glycines, was planted in 1994 and 1996, and corn was planted in 1995 and 1997. When the experiment was initiated in 1994, the number of eggs per plot averaged 1,700 (range = 75-24,000)/250 cm3 soil. In 1994, lower Pf/Pi in the no-till system was significant at P = 0.16. When corn was planted in 1995, Pf/Pi was lower in no-till plots (P = 0.04). In 1996 soybean was planted and Pf/Pi also was lower in no till plots (P = 0.01). However, in 1997 corn was planted and tillage did not affect Pf/Pi (P = 0.66).
