Effect of temperature on productivity of common bean (Phaseolus vulgaris L.) sown during the fall in southern Sonora, Mexico

During the last ten years, agricultural area in southern Sonora, Mexico, has had greater hourly temperature oscillation associated to growth cycle of common bean sown during fall. The objective this work was evaluate thermal impact caused by high frequency extreme temperatures on production commercial fall-winter season 2021-2022. Four fields were selected based irrigation system used (drip and gravity), two each Yaqui Mayo Valleys. Weather data recorded automated weather station network Sonora closest field also from digital sensors installed within crop. results obtained indicated that with sensor, provided better relationship taken than stations. periods ≥ 33 °C affected trifoliates, flowers, pods both cultivars evaluated Pinto Saltillo Azufrado Higuera. highest grain yield 3,860 kg ha-1 drip irrigated Valley a total water sheet 42 cm, followed gravity 3,560 62 cm.
