Sowing Time, Plant Growth Regulators and their Application Scheduling Affect Quality Traits of Wheat (Triticum aestivum L.)

A field experiment was conducted during winter (rabi) seasons of 2020-21, 2021-22 at Research farm, seed technology research center, Department of Plant Physiology, College of Agriculture, JNKVV, Jabalpur, Madhya Pradesh to study the response of sowing time, plant growth regulators and their application scheduling on quality traits of wheat. The experiment consisting of 3 sowing dates (D1-15th November, D2-15th December, D3 - 15th January), 3 Spray scheduling at different stages (A1-Vegetative stage, A2-Anthesis stage, A3-Vegetative + Anthesis stage) and 7 Plant Growth Regulators (H1: Cycocel @1000 ppm, H2: Salicylic acid@400ppm, H3: Salicylic acid@800ppm, KCl@1%, H4: Ascorbic acid@10ppm, H5: Thiourea@400ppm, H6: Water spray and H7: Control) making 63 treatment combinations, replicated thrice in a split plot design. The crop sown at normal sowing time showed significantly positive affect on quality traits of wheat than the late sown crop. Spraying of plant growth regulators salicylic acid@400ppm and 800ppm along with other plant growth regulators at different growth stages have positive effect on seed quality and improve germination %, seedling length, seedling dry weight, seed vigour index I and II of wheat crop.
