Abstract:

A field experiment was conducted to investigate the effect of irrigation levels using drip irrigation system for Lettuce crop grown under polyhouse and in open field condition during winter season (November-February) for two consecutive years (2014-15 and 2015-16) at the Experimental Farm area of Precision Farming Development Centre Project, Indian Institute of Technology, Kharagpur, India. Reference evapotranspiration was estimated using FAO-56 Penman Monteith approach. The total water requirement of Lettuce crop was estimated to be 219 mm and 339 mm for polyhouse and open field condition respectively. There were total five treatments, four irrigation levels (120%, 100%, 75% and 50% of crop water requirement) using drip irrigation system in polyhouse and one treatment 100% crop water applied through drip in open field condition. The effect of these treatments were studied for biometric and crop yield response. The research trials showed that 100% of water requirement met with drip irrigation under polyhouse (T2) resulted in maximum plant height, head diameter, number of leaves, fresh and dry weight of leaves and crop yield. Open field cultivation produces lowest yield compares to all irrigation level treatments under polyhouse.
