During the monitoring, period Bangladesh suffered from below averagerainfall and temperature compared with the previous five years (-28% rainfalland -0.3°C). Crop condition was favorable in southern Rangpur, EasternRajshahi, most of Dhaka (except the central part), western Sylhet, southernKhulna and Barisal, and middle-western Chittagong, with maximum VCI ranges from0.8 to 1.0. In northern Rangpur, southern Rajshahi, central Dhaka, southernSylhet, northeastern Khulna and northern Barisal, crop condition was averagewith maximum VCI ranging between 0.5 and 0.8. At the national level, cropprogress was above average from early January to the early April in northernKhulna, central and western Sylhet, and western Rangpur.

In spite of below-average rainfall andtemperature over much of the country, biomass accumulation was favorable.
