Average Plant Heights - There was a significant plant height difference between the irrigated and non-irrigated seed corn inbreds. Table 2. In general across all inbreds, without irrigation, the plants were stunted. Plants were 17.4% taller early in the season and 22.6% taller later on in the season in the irrigated plots. Pride #4,2,3, INB 507, 508 and Hyland T50-B1 were the tallest seed corn inbreds while INB 503, Hyland T29-11 and INB 502 were the shortest. Fig. 7., Fig. 8, Table 3.
