This monitoring period from July to October covers the growing and harvesting stages of maize. Winter wheat was harvested from June to August. The sowing of winter wheat, to be harvested next year, started in September and October. The proportion of irrigated cropland in Uzbekistan is 30% and regular rainfall is crucial to sustaining the growth of most crops. Among the CropWatch agroclimatic indicators, RAIN increased by 23%, and TEMP, RADPAR, and BIOMSS were slightly above average (+0.2°C, +1%, and +5%). Although total precipitation was above average, most of it fell in October, which helps with the germination and establishment of winter wheat. 

The national average VCIx was only 0.77, CALF was equal to the 5YA. Cropping Intensity (CI) was slightly above average (119%, +3%), and the crop production index (CPI) was 0.96. According to the crop condition development graph based on NDVI and the spatial distribution of NDVI profiles, crop condition was slightly below average since late August. More than 37.3% of the cropland of Uzbekistan had below-average crop conditions during the whole monitoring period, and these areas were mainly in the north of Kashkadarya state, the south of Samarkand state, and the middle of The Autonomous Republic of Karakalpakstan. The maximum VCI map shows that the middle and eastern of the Eastern hilly cereals zone and the northwest of the Aral Sea cotton zone had low values of VCIx.

Overall, the prospects for crop production in Uzbekistan were slightly unfavorable.

 

Regional analysis

Based on cropping systems, climatic zones, and topographic conditions, Uzbekistan can be divided into three agro-ecological zones (AEZ): Central region with sparse crops (199), Eastern hilly cereals zone (200), and Aral Sea cotton zone (201).

Central region with sparse crops

According to the crop condition development graph based on NDVI, the crop condition in the region was above average from August to early October. As for the agroclimatic indicators, RAIN increased by 20%, TEMP increased by 0.8°C and RADPAR was equal to the 15YA. BIOMSS increased by 2%. Both CALF and CI were equal to the 5YA. The regional average VCIx was 0.84. Crop prospects for this region were normal. However, the area of cropland in this region is very small.

Eastern hilly cereals zone

Since most of the cropland of Uzbekistan is concentrated in this region (more than 70%), the trend of the NDVI development graph of this region is similar to the national level, which was slightly below average since late August. Among the CropWatch agroclimatic indicators, RAIN increased by 26%, and TEMP, RADPAR, and BIOMSS were slightly above average (+0.2°C, +1%, and +6%).  CALF increased by 6%, CI increased by 2%, regional VCIx was 0.79, and CPI was 1.01. Overall, the prospects for crop production in Uzbekistan are expected to be normal.

Aral Sea cotton zone

Compared to the 15YA, RAIN had a large decrease by 45%, while TEMP increased by 0.9°C. RADPAR and BIOMSS were equal to average. According to the crop condition development graph, crop conditions were below the five-year average during the whole monitoring period. CALF decreased by 18%, CI increased by 2%, regional VCIx was only 0.69, and the CPI was only 0.79. Therefore, the prospects for crop production in this region were slightly unfavorable.
