CropWatch indicators show average crop condition in the northeastern and southern regions (including Sylhet and Khulna), but above average conditions elsewhere. The maximum VCI values observed were above 0.8 in most areas, except in the two mentioned regions of Sylhet and Khulna where VCIx was between 0.5 and 0.8. The low NDVI values around July indicate the completion of Aus harvesting and the sowing of A man rice and sorghum. Crop condition development was similar to the previous five years’ maximum. Rainfall (RAIN) was 23% higher than average, which benefited the sowing and growing of A man rice. Temperature (TEMP) and PAR (RADPAR)were average, but biomass (BIOMSS) was 4% higher than the recent five-year average.
