Abstract: Capsicum annum L. (Syn: Capsicum frutescens L., family: Solanaceae) is an herbaceous spice plant cultivated in tropical and subtropical conditions in different countries of the world. In India it is commonly known as “Lal Mirch”. The present study deals with response of UV-B radiation on different growth parameters of capsicum crop. Plants were grown in the field and exposed to supplemental UV-B radiation (280-320nm) for 1 hr and 3hr regularly supplied by the sunlamp, 300 watt from sowing till seedling stage. The total UV-B irradiation received by the plants from the lamp was 24.23 Jm-2s-1. The seed germination percentage was significantly decreased by 1 hr and 3 hr UV-B irradiation. The exposure of 1 hr UV-B irradiation showed promotory response on chlorophyll content and biomass of plumule and cotyledons while exposure of 3 hr of UV-B irradiation showed inhibitory effect on growth and chlorophyll content of seedlings. Current findings suggest ways to increase crop yield to cope the adverse effect of abiotic stress.
