Measured weather data were not available in 20% of the buffers); hence, we used weather data (including all variables) from NASA-POWER. Requested information include: dominant crop rotations and proportion of each of them to the total harvested area, sowing window, dominant cultivar name and maturity, and optimal plant population density (CONAB, 2019). To portray most dominant practices in sugarcane farms, 3 main cycles of ratoon crops of 12-month duration each were simulated at each location: early (April-15), mid (Aug-15), and late planting (Nov 15). If you want to see a sample data set, you can download one here or you can ask for it by reaching out to us at gyga. Management practices for each RWS buffer zone were retrieved from local EMBRAPA agronomists and other experts.Yield gap (Yg) was calculated as the difference between long-term average Yw (rainfed crops) or Yp (irrigated crops) and average (2012-2017) farmer yield. In all cases, solar radiation was retrieved from NASA-POWER, which has shown good correlation with measured solar radiation (Bender and Sentelhas, 2018; Monteiro et al.

RWS buffer zones accounted for 50, 25, 47, 52 and 15% of total harvested area for rainfed soybean, rainfed maize, rainfed sugarcane, irrigated lowland rice, and rainfed upland rice while the agro-climatic zones where these sites were located accounted for 86, 66, 88, 72 and 63% of national area for these crops. Major crops are soybean, maize, sugarcane, and rice which account for 90% of total crop area, and (except for rice) the country is one of the largest producers and exporters of these crops.
Assessment of NASA / POWER satellite-based weather system for Brazilian conditions and its impact on sugarcane yield simulation. Experiments for upland rice were not explicitly managed to eliminate yield-limiting factors; as expected, the simulated yield was above the measured yield. Comparison of simulated and observed phenology (left) and grain yields (right) for rice (top), soybean (middle), and maize (bottom).Brought to you in a green hue material with a 'Brazil' logo design and a copped fit, what more could you want?
