Abstract
The purpose of this study was to test the Aqua Crop model in simulate canopy cover and above ground biomass of maize under three soil water regimes in a semi-humid environment. The trial at the Cambodian Agricultural Research and Development Institute (CARDI), Cambodia, over the 2015-2016 growing season used 3 plots each with three water regimes. The comparison between the observations and simulated values using statistics indicators R2, RMSE, nRMSE, Nash, D, and MBE were 0.93, 10.9%, 46.6%, 0.36, 0.9, and 0.37t/ha for canopy cover (overestimation) and 0.97, 1.91 t/ha, 46.9%, 0.44, 0.89, and 0.43 t/ha (overestimation) for biomass respectively.

| Other | The 18th Australian Agronomy Conference will be held at the Mercure Ballarat Hotel and Convention Centre, Victoria from 24-28 September 2017. The Australian Agronomy Conference is the meeting place for Agronomists; it supports research and the community of Agronomists by connecting Agronomy communities across Australia to each other. The theme for the 2017 conference is “Doing more with less”. A central plank of Australia’s productive output is agriculture, worth over AUD$13.6 billion exported annually. Agronomy is key to ensuring that farmland is productive across Australia’s diverse landscapes. Innovation in machinery and precision technologies, plant species and varieties, soil and plant management may allow the agronomist of today to successfully help agricultural producers thrive. These innovations are timely as the world deals with increasingly variable climates, environmental degradation, and a more developed global community that requires more diverse products from agriculture. |
