For July to October2014, accumulated rainfall in Iran was above the thirteen-year average, while temperature and RADPAR were close to average. The harvest of summer crops(potato and rice) was completed before October; winter wheat and barley were planted from September. The CropWatch agroclimatic indices for the current season indicate favorable conditions for summer crops, which is confirmed by the increase of the BIOMSS index by 30%. The national average of VCIx (0.65) indicates just above average conditions. Poor growth conditions occurred in the RazaviKhorasan, north Khorasan, and the center of Golestan provinces in the northeast region, and the Ardabil, Zanjan, and Hamadan provinces of the northwest region.Conditions close to or above the five-year average are mainly distributed inthe Khuzestan, Kermanshah, and Fars provinces in the southwest and in Mazandaran province in the central-north. Overall, the situation of most summer crops is poor and the outcome is below last year and the five-year’s average. The outcome of the rice crop, however, is favorable in Mazandaran province, aprovince accounting for about half of the rice producing areas in the country.
