Water Saving Using Thermal Imagery-Based Thresholds for Timing Irrigation in Potatoes under Drip and Furrow Irrigation Systems

چکیده
Under the current water crisis in agriculture, irrigation methods for saving and conserving are necessary. However, these must guarantee an appropriate yield with a concomitant economic benefit reduced environmental impact. In this study, two thresholds timing (IT) based on thermal imagery were analyzed UNICA potato variety three trials under drip (DI) furrow (FI) during 2017–2018 Lima, Peru. The control (T1) remained at >70% of soil field capacity. For other treatments, defined stomatal conductance light saturation (T2: 0.15 T3: 0.05 mol H2O m−2s−1) crop stress index 0.4 0.6) canopy temperature. An integrated (IIN) was established valuation treatments using criteria high fresh tuber (FTY) low total amount irrigated water, production cost (PC), C emissions (TE) score. FI-T2 (0.69–0.72) DI-T3 (0.19–0.29) showed highest lowest IIN value, respectively. FTY T2 not significantly FI, resulting lower PC regarding DI–T2 emphasizing usefulness determining watering schedules potatoes systems.

متن کاملErosion Control in Furrow Irrigation Using Polyacrylamide
Currently gravity irrigation remains the most widely used in agricultural areas and 90 percent of plantings, the water is applied to the plots by gravity. One of the main problems with these systems is erosion, which is a by product of the erosive forces of water over the row, which brings soil loss and therefore decreases in crop yield. Erosion is the removal of surface soil material caused by...
