Abstract: An experiment entitled “Effect of thiourea and salicylic acid on growth, yield and quality of gladiolus” was carried out at Horticulture Section, College of Agriculture, Nagpur (M.S.), India during the year 2017-18 with nine treatments of thiourea and salicylic acid viz., T₁ – Thiourea 1%, T₂ – Thiourea 2%, T₃ – Salicylic acid 100 ppm, T₄ – Salicylic acid 150 ppm, T₅ – Thiourea 1% + Salicylic acid 100 ppm, T₆ – Thiourea 2% + Salicylic acid 100 ppm, T₇ – Thiourea 1% + Salicylic acid 150 ppm, T₈ – Thiourea 2% + Salicylic acid 150 ppm and T₉ – Control in randomized block design. The results revealed that, the T₇ – Thiourea 1% + Salicylic acid 150 ppm recorded significantly minimum days for 50% sprouting of corms and maximum shoots plant^-1, leaves plant^-1, longevity of spike, spikes ha^-1, diameter of spike, length of rachis, vase life whereas, T₄ – Salicylic acid 150 ppm recorded minimum days for 1^st spike emergence and days for opening of first floret.
