The effect of deficit irrigation on yield and water use efficiency of drip irrigated capsicum under the naturally ventilated polyhouse was studied through field experiment. In this study, six different levels of drip irrigation equivalent to 100%, 90%, 80%, 70%, 60% and 100% (control without mulch) of crop evapotranspiration with four replications were considered for their effect on crop yield and water use efficiency inside the naturally ventilated polyhouse. Capsicum (Capsicum annuum L. Indra Variety) plants were grown under the naturally ventilated polyhouse. The maximum crop yield was found in case of 80 % irrigation level (42.64 t/ha) and the maximum water use efficiency was also recorded in the same treatment (1296.48 kg/ha-cm). Thus, the results revealed that all the vegetative parameters, quantity parameter and water use efficiency were found maximum at drip irrigation level equal to 80 % of crop evapotranspiration under the naturally ventilated polyhouse.
