摘要：An experiment was conducted in wooden boxes to evaluate water use efficiency, biomass production, nitrogen and potassium uptake and yield of tomato plants ( Lycopersicon esculentum) grown under flood irrigation (FI) and surface drip irrigation (SDI). Leaf area, leaf area index, biomass production and yield of tomato plants were significantly (P<0.05) higher in SDI than FI treatment. Biomass production (g/plant) was 53.3 and 42.2 and yield of tomato (kg/plant) was 1.27 and 0.99 in SDI and FI treatments, respectively. Surface drip irrigation increased water use efficiency (Kgm -3 ) of tomato plants by two fold (37.88) compared to flood irrigation ( 19.88). Significantly (P<0.05) higher concentrations of nitrogen in leaf (3.22%) and stem (2.62 %) were measured for tomato plants grown under SDI than FI (2.63 and 2.19 %). Potassium concentrations on the other hand, showed no significant differences. DOI: http://dx.doi.org/10.3329/jasbs.v38i2.15611 J. Asiat. Soc. Bangladesh, Sci. 38(2): 207-215, December 2012
