Effect of Deficit Irrigation on Growth and Yield of Tomato underDrip Irrigation in Shade Net House

摘要

The effect of deficit irrigation on growth and production of drip irrigated tomato under shade net house was studied through field experiment. Four different levels of drip irrigation equivalent to 100%, 80%, 60% and 40% of crop evapotranspiration with five replications were considered for their effect on crop growth and crop yield inside the shade net house. Tomato (Solatium Lycopersicon, Badshah Variety) plants were grown under the shade net house with 50% shade. Plant height, number of leaves andindividual fruit weight were found to be highest with 80 % irrigation, giving highest yield of 108.30 t.ha'. Actual irrigation water application between 1.62 and 4.58 mm.day~(-1) was thus recommended for tomato crop in a shade net house.
