Evapotranspiration Rates of Three Sweet Corn Cultivars under Different Irrigation Levels

Understanding plants’ response to different irrigation levels is essential for developing effective scheduling practices that conserve water without affecting plant growth and yield. The objective of this study was evaluate the responses three sweet corn ( Zea mays var. saccharata ) cultivars 1170, 8021, Battalion under (50%, 75%, 100%). Irrigation treatments were based on soil moisture management allowable depletion. Replicated trials conducted, in an open field using 1-gal containers, at Tropical Research Education Center, Homestead, FL. A drip system with microsprinklers used irrigation. Daily crop evapotranspiration (ET c rates measured a digital scale differences weights containers plants. Reference o calculated FAO-Penman-Monteith equation. Crop-coefficient (K values from ET . In addition, leaf area, stomatal conductance, fresh biomass measured. Total amounts corresponding 50%, 100% 116, 162, 216 mm, total 128, 157, 170 respectively. two deficit (50% 75%) resulted reduction compared treatments. Results also showed 75% treatments, K usually greater than 1 reached as high 1.5. Additionally, area weight 50% treatment mostly lower or
