| dc.description | Common bean crop is grown in Goiás state in three crop seasons, "wet?, ?dry?, and autumn/winter. In "dry" crop season, common bean yield is lower and it can be attributed in large part to the water deficit during its cycle. The use of supplemental irrigation can be an alternative to overcome this stress and increase grain yield. The objective of this study was to quantify the impact of water stress in "dry" season common bean and the irrigation depth required to mitigate this stress, using the CSM-CROPGRO-Dry bean simulation model. The model was calibrated and evaluated against observed data set for Pérola cultivar. Grain yield for six sowing dates (10/1, 20/01, 30/1, 10/2, 20/2, and 28/2) and three soil classes (Oxisol, Ultisol, and Inceptisol) were simulated considering growth under rainfall and growth with supplemental irrigation, using daily climatic data of 26 weather stations in Goiás for the period of 33 years. The relative impact of water deficit, estimated by the grain yield gap in both cases, was 48%. Soil classes had low impact on average values of irrigation depth required as well as on irrigated grain yield. The irrigation depth required increased from 70 to 157 mm and the grain yield decreased from 3,813 to 3,510 kg ha-1 with the advance of sowing date. | pt_BR |
