| Kuvaus: | Introduction. Simulation models are a tool to study the behavior of crops under different climatic and water conditions and agronomic management practices. Objective. To evaluate the AquaCrop model for yield and water productivity in soybean var. CIGRAS-06. Materials and methods. The study was carried out at the Estación Experimental Agrícola Fabio Baudrit Moreno of the University of Costa Rica, in Alajuela, Costa Rica from June 6th to October 23rd 2018. The AquaCrop v 7.1 model was used to simulate the development of soybean cultivation. Simulated data of plant canopy cover, biomass production and yield were compared against experimental data from a plot of soybean variety CIGRAS-06. Soil parameters measured in the field and generated using pedotransfer equations were used. Results. The predictions of yield, total biomass, and coverage were good (similarity values (d) ≥ 0.97), but the predictions of leaf coverage during the beginning of the crop cycle are should be improvement. Differences observed in the two types of soil parameters used, did not significantly affect the final simulation. Conclusions. Overall, modeling with AquaCrop successfully simulated soybean yield, biomass, and leaf coverage. The simulation of water productivity was higher than other values reported in the literature. |
