The reporting period corresponds to the growing of Aus rice and the planting of Aman. Overall, CropWatch indicators show below average crop condition for the country. Excess monsoon rainfall (RAIN, +7%) caused flooding and damaged the standing crop mainly in Rangpur, Sylhet, Dhaka, Barisal, and Khulna. The overall biomass accumulation potential (BIOMSS) and the cropped arable land fraction (CALF) remained at the level of the previous five-year average. Temperature (TEMP) remained average as well, while radiation was low (RADPAR, -4%), a very negative factor in a country where sunshine is a dominant limiting factor. The maximum VCI values over the country ranged from 0.5 to 0.8, pointing to average crop condition. In the coastal and the northern regions of the country the spatial NDVI profiles started dropping from early May and continued till the end of the reporting period. The NDVI profiles for the central regions of the country increased from early May to June and started dropping in early July. In Sylhet, the spatial NDVI profiles sharply dropped in early May, then gained for some time and again started dropping till July. Primarily due to flood damage, low photosynthetic activity, and the below average NDVI trend, CropWatch ranks the crop prospects as poor, especially in the northeast.
