【 摘 要 】

A field experiment was conducted during March-August 2017 at Plasticulture farm College of Technology & Engineering, Udaipur. Randomized block design (RBD) was adopted for conducting field trial with six levels of irrigation viz., 100, 90, 80, 70, 60 and 100% (control without mulch) of crop evapotranspiration and 4 replication. Capsicum (shimla mirch locally known in Udaipur) cv Indra was irrigated with drip irrigation (also known as trickle irrigation) technique. Measurements of crop biometric parameters namely plant height, number of leaves and individual fruit weight was done at pre scheduled time throughout the crop season. Results revealed that biometric parameters found maximum in case of 80% irrigation level whiles minimum in 60% irrigation level treatment. The highest yields (42.64 t/ha) was also recorded in the same treatment. Therefore, it can conclude that by scheduling irrigation to meet 80% of crop ET will result in optimum crop yields and enhances crop water use efficiency of capsicum grown inside naturally ventilation polyhouse (NVPH).
