Crop condition in Argentina was generally favorable in 2014. Currently, the harvesting of winter wheat is ongoing. The planting of maize is virtually over, while the planting of soybean is still ongoing. From July to October, Argentina experienced wet and warm climatic conditions which are beneficial for the emergence and development of maize and 1st season soybean. Compared with the average,Argentina experienced 12% more rainfall, 1.9°C degree higher temperature, and average PAR. Spatial NDVI patterns compared to the 5-year average and the corresponding NDVI departure cluster profiles reveal that NDVI of most arable land in Argentina is above average. Major wheat producing regions (including southern Buenos Aires, Cordoba, and Santa Fe) are even better off. Crop condition development graphs based on NDVI present the evolution of winter crops since August. The higher than the previous five years’ maximum NDVI series confirms above average winter crop condition.However, the 1.5°C degree and 2.2°C degree higher air temperature in the two top wheat producing states (see also figure 2.3(c, d)) shortens the grain filling stage and accelerates wheat maturity, thus hampering yield formation.Compared with the assessment carried out in August, CropWatch revised down the winter wheat production to 13 million tons, still 22% up over last year but 4%down from the August estimates. The increased production is due to the expanded planting area because of high domestic prices. (See also table B.1 in Annex B.)
