Abstract: Carnation is an important flower crop having great commercial value as a cut flower due to its excellent keeping quality, wide array of colour and forms and from medicinal point as cardiotonic, diaphoretic and alexiteric. The experiment was conducted at Hi-Tech Horticulture of RAU Pusa, Bihar to study the effect of climatic parameters on performance & evaluation of carnation inside the polyhouse compared to outside. Observations were undertaken to record and evaluate various climatic parameters i.e. ambient air temperature, relative humidity etc. inside and outside the polyhouse, plant growth parameters among three verities Corex Collina and Gionek. Plant parameters like plant height, days to budding and flowering, plant mortality, flowers per square meter different treatments were measured under polyhouse and outside the polyhouse. The average increases in maximum and minimum temperature inside greenhouse were found 5.72°C and 7.82°C respectively. The average increases in maximum and minimum relative humidity inside greenhouse were found 4.67percent and 10.62 percent respectively. Corex recorded highest plant height (103cm) while variety Gionek (81cm), was shortest types. Collina (5.5%) was found very resistant to mortality and varieties Corex and Gionek fairly resistance to mortality with (8.8) & (12.2%) % respectively. Maximum number of flowers per square meter was recorded in variety collina (33.58) and variety which was recorded minimum number of flowers per square meter (25.67) was Gionek. Variety Corex (30.89) was mediate in no of flowers per square meter. Plant height, plant mortality, earliness in budding & flowering, average yield per plant and productivity was minimum in outside the polyhouse and maximum in inside the polyhouse.
