Relative Turgidity Technique for Scheduling Cotton (Gossypium hirsutum) Irrigation1

  1. L. N. Namken2

Synopsis

Synopsis

Cotton irrigations were adequately scheduled according to variations in the relative turgidity of the plant leaves sampled between 2:30 and 3:00 p.m. Cotton plants were able to endure short periods of severe plant moisture stress (66 to 62% relative turgidity) without significant yield reductions. Long periods of moderate to severe plant moisture stress (70 to 62% relative turgidity) during the bloom stage of plant growth caused significant yield reductions.
