Synopsis Alfalfa plants grown under 14 hours of light were more vigorous in growth, had larger leaves and longer internodes, and were taller than those grown under 12 hours. Flowering of plants was profuse in the longer daylength, but was sparse, if present at all, under shortday conditions. Spraying with different growth‐regulators altered the heights of plants, length of internodes, and flowering response. Formative effects were also evident from treatment with certain of the chemicals.
