An experiment was conducted at Botanic Garden, Department of Seed Science and Technology, Tamil Nadu Agricultural University, Coimbatore. To study the effect of plant growth regulators on growth and yield of glory lily (Gloriosa superba L). Among different plant growth regulators applied spray of GA₃ @ 100 ppm at 10^th and 20^th days after anthesis recorded increased plant growth, number of pods plant^-1 (39), pod set percentage (94%), maximum pod yield per plant (291.87 g), maximum seed yield per plant (193.80 g), accompanied with the maximum seed germination (52%), dry matter production (189.0 mg) and vigour index (1321). Our data show that GA₃ @ 100 ppm at 10^th and 20^th days after anthesis enhanced seed yield and quality compared to control.
