The Uruguayan rice sector has been one of the most successful and most integrated agricultural industries in the country. Rice yields in Uruguay have increased at one of the highest annual rates worldwide (145kg-1 ha-1 yr-1 from 2000 to 2017). However, this trend has shown a marked slowdown in recent years, which may be indicating that average rice yields approach the biophysical yield ceiling (Figure 1). Indeed average farm yields often begin to plateau when they reach 75 to 85% of the yield potential (CASSMAN et al., 2003; LOBELL et al., 2009). Determination of rice yield potential in Uruguay, is essential to identify opportunities for future yield gains. Also unknown is if the high increase in rice yield in Uruguay was partially determined or not by climate change. Due to current high inputs costs and low rice prices, keeping rice yields trend is critical for the viability and sustainability of the crop in Uruguay. The aims of this work were: firstly, to estimate rice yield potential (Yp) and current exploitable yield gaps (Yg) at regional and local-farm levels in Uruguay, secondly, to analyze current rice yield trends in Uruguay and to determine to which degree the incipient yield plateau can be attributed to a biophysical limit and thirdly to compare results with other rice producing countries included in the Global Yield Gap Atlas for which rice yield potential and yield gap estimates are available. |
