Fig. 1. Mean cumulative dry matter yield for glandular-haired alfalfa cultivars not commercially released (GN); glandular-haired, commercially released alfalfa cultivars (GR); and non-glandular-haired, commercially released alfalfa cultivars (NR) as a function of sequential harvest number. Data are for the control (no insecticide) treatment at Indiana and Ohio from 1996 to 1998. Regression statistics are presented in Table 6.
