Thiourea and salicylic acid influences growth, yield and quality of gladiolus

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 1st spike emergence and days for opening of first floret.
