The reporting period includes the harvest of spring wheat from August to September, followed by the planting of winter wheat in October. The nationwide rainfall amount was 283 mm, 3% above the 15YA average. Temperature increased slightly (14°C, 0.2°C) while solar radiation was somewhat below average (RADPAR, 766 MJ/m², -3%). The potential biomass was below average (-1%). Agronomic conditions were generally favorable: good values of VCIx (0.92), cropping intensity (CI 98%) and cropped arable land fraction (CALF, 100%) were observed. 

The NDVI development graph indicates that crop condition had declined to below average levels in August, presumably due to the rainfall deficit. The national VCIx map shows that crop conditions in about 67.4% cropped area were close to or slightly above the 5-year average, but the other areas remained below average. According to the VCIx distribution map, VCIx was satisfactory in most cropped areas of the country (above 0.8), indicating fair crop prospects, while low values were scattered in the southern area. The crop production index (CPI) was 1.16. Above-average rainfall in early October helped with the establishment of winter wheat. Overall, production prospects were average.



Regional analysis

Regional analyses are provided for three agro-ecological zones (AEZ) defined by their cropping systems, climatic zones, and topographic conditions, including Northern Belarus (028, Vitebsk, the northern area of Grodno, Minsk and Mogilev), Central Belarus (027, Grodno, Minsk and Mogilev) and Southern Belarus (029) which includes the southern halves of Brest and Gomel regions.

Northern Belarus recorded a radiation decrease (-1%) combined with slightly higher temperatures (+0.3°C) and rainfall (+5%).  And potential biomass decreased by 3% below average. The VCIx had reached 0.95, and CALF had reached 100%, with an CPI of 1.19. The NDVI development curve was generally near average. 

Central Belarus also experienced less sunshine (-4%) and slightly higher temperature (+0.3°C) and decreased rainfall (-2%). Similar to Northern Belarus, high CALF (100%), VCIx (0.90) and CPI (1.15) were also recorded. The NDVI growth curve was generally near the average trend from July to October. Conditions were near average.

Precipitation in Southern Belarus was above the 15YA average level (+11%), and the temperature was slightly lower by -0.1°C and radiation decreased by 8%. Potential biomass was expected to increase by 5%. The CALF and the VCIx were 100% and 0.88 respectively, with a CPI of 0.99. Conditions were average.
