The study was conducted to find out the effect of GA3 and chemicals on growth and yield of gladiolus at Nagpur during October, 2016 to April, 2017. The experiment was laid out in Randomized Block Design with three replications. The treatments comprised of three different chemicals viz., Gibberellic acid (GA3), Potassium nitrate (KNO3) and Calcium nitrate Ca(NO3)2 with eleven treatment combinations viz. T1 (GA3 100 ppm), T2 (GA3 200 ppm), T3 (KNO3 1%), T4 (KNO3 2%), T5 Ca(NO3)2 1%), T6 (Ca(NO3)2 2%), T7 (GA3 100 ppm+KNO3 1%), T8 (GA3 200 ppm+KNO3 2%), T9 (GA3 100 ppm+Ca(NO3)2 1%), T10 (GA3 200 ppm+Ca(NO3)2 2% and T11 (control). The results revealed that, maximum vegetative growth in respect of height of plant (68.05), leaves plant-1 (28.97) and leaf area(172.19), earliest flowering in respect of first spike emergence(52.99), opening of first floret(63.29) and 50 per cent flowering(71.17), maximum flowering span(24.84) and longevity of flowers(15.94) in gladiolus were recorded with the treatment GA3 200 ppm + Ca(NO3)2 2%. Similarly, yield parameters like spikes plant-1 (2.90), corms plant-1(2.96) and cormels plant-1(45.13), spikes plot-1 (95.66), corms plot-1(95.60)  and spikes ha-1(2.96),corms ha-1(3.00) in gladiolus were recorded maximum with the treatment GA3 200 ppm + KNO3 2%.

Key words: Gladiolus, Gibberellic acid, Spike, Corm, Potassium nitrate and Calcium nitrate.
