Abstract
Calibration and validation of FAO-AquaCrop model to estimate the total biomass and yacon root yield
Highlights
The management of water resources demands detailed studies, since fresh water is an indispensable and exhaustible natural resource, with a fundamental role in the development of living beings[1,2]
It is observed that the value calibrated in the Autumn showed a deviation of −8.6% for the harvest index (HI), while the Winter and Spring plantings, times used to validate the model showed 7.6% and –1.4% of deviation, respectively
The values of harvest index (HI) obtained in the field tests were similar to those obtained by other authors[25,28,29] for common potato (Solanum tuberosum)
Summary
The management of water resources demands detailed studies, since fresh water is an indispensable and exhaustible natural resource, with a fundamental role in the development of living beings[1,2]. The AquaCrop model, developed by FAO, provides a good balance between robustness, simplicity and precision of the output, and it can be used for a wide variety of crops[12,13] using few input parameters. They are found in the literature on potato studies[14,15,16], there is still limited information on modeling with yacon
