Abstract
Abstract A 2-year field study was conducted on a fine sandy loam soil near Vincennes, Ind., to evaluate tomato (Lycopersicon esculentum Mill. cv. Sunny) response to trickle irrigation and black polyethylene mulch. Use of trickle irrigation resulted in higher petiole P and B and lower Zn concentrations than using no irrigation. Trickle-irrigated soils had lower soil NH4-N, NO3-N, and K and higher Mg concentrations than non-irrigated soils. Soil NH4-N, NO3-N, and Mg concentrations were higher in soils mulched with polyethylene than in soils without mulch. The use of trickle irrigation increased plant height, whereas polyethylene mulch increased plant spread and dry matter production. Early, late, and total yields were improved with all trickle irrigation and polyethylene mulch treatments. Total yields were 66%, 70%, and 123% greater for plants grown with polyethylene mulch, trickle irrigation, and polyethylene mulch plus trickle irrigation, respectively, than control plants.
