Fig. 2. Plant height for (A) cultivars (Hardin, CX232, and Spansoy 250), (B) planting dates (early May and late May), and (C) management systems (CT, Irr. = irrigated, conventional tillage management system at Arlington; CT = conventional tillage at Arlington; NT, Irr. = irrigated, no-tillage management system at Arlington; NT = no-tillage management system at Arlington; and Sand, Irr. = irrigated, conventional tillage management system at Hancock) during 1998-1999. Reproductive growth stages are shown for the two planting dates. Vertical bars represent the LSD (P ≤ 0.05) on dates when significant differences were found.
