Effect of thiourea and salicylic acid on growth, flowering and yeild of gladiolus

Abstract

An experiment entitled “Effect of thiourea and salicylic acid on growth, flowering and yield of gladiolus” was carried out at Floriculture Unit, Horticulture section, College of Agriculture, Nagpur (M.S.) from October, 2017 to April, 2018 with nine treatment combinations in Randomised Block Design. The treatments comprised of different concentration 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. The results revealed that, significantly minimum days for sprouting of corms, maximum sprouting percentage of corms, plant height, leaf area, flowering span, spikes plant-1, length of spike and florets spike-1 were registered with the plants treated with Thiourea 1% + Salicylic acid 150 ppm which was closely followed by Salicylic acid 150 ppm and 50 per cent flowering was recorded earliest with the treatment of Salicylic acid 150 ppm.
