Synopsis Gibberellic acid promoted the elongation of internodes but decreased the leaf area. Stover weight and grain yield were increased when gibberellic acid was applied near pollination. Early treatments at weekly intervals decreased grain yield. The yield of Hy2 ✕ O7 was affected more than that of Wf9 ✕ Ml4.
