Effect of plant growth substances on yield, quality and economics of golden rod (Solidago canadensis L.)

Effect of plant growth substances on yield and quality of golden rod (Solidago Canadensis L.) experiment was carried out during March 2022 to November 2022 at College Farm, College of Horticulture, SDAU, Jagudan, Gujarat. The experiment was comprised of two factors time of spray with three levels viz., T₁ (30 DAT), T₂ (45 DAT) and T₃ (30 and 45 DAT) and plant growth substances with six levels. viz., p₁(GA₃ @ 100 ppm), p₂(GA₃ @ 150 ppm), p₃ (Triacontanol @ 20 ppm), p₄ (Triacontanol @ 30 ppm), p₅ (CCC @ 500 ppm), p₆ (CCC @ 1000 ppm). T₂ (Spray at 30 DAT + GA₃ @ 150 ppm) found superior on yield and quality parameters viz., number of panicle per plant, number of panicle per plot, number of panicle per hectare, vase life of panicle and longevity of panicles on plant.
