A field experiment was conducted to optimize requirement of potassium and stage of harvest for gladiolus cv. Summer Pearl for corm and cormel production. Application of 150 kg/ha potassium and harvesting of spike at emergence stage significantly increased plant height, number and weight of corms and cormels over lowest dose (50 kg/ha) of potassium. However, application of potassium @ 100 kg/ha is beneficial for corm and cormel production from commercial point of view.
