Warmer-than-usual thermal conditions and infrequent rains facilitated the successful ending of the spring sowing campaign.
The development of winter crops is advanced by 1-2 weeks.
Biomass accumulation of winter wheat is close to normal in the Central Okrug, but it is promisingly positive in the Southern Okrug.
The rainfall deficiency has led to an accelerated decrease of the soil moisture under spring crops, primarily in the Near Volga Okrug.
The period of review started and ended colder than usual, but from 10 May until 10 June daily temperatures typically fluctuated well above the average, resulting in a positive thermal anomaly of between +2 and +4°C for the period of review in the central and southern agricultural areas of Russia.
Plentiful precipitation (60-100 mm) was experienced between the Baltic Sea and the Black Sea, along the western border of Russia.
The rains during the last days of May in the Central Okrug were especially beneficial for spring and summer cereals, and favourably replenished the below-average soil moisture levels, just before the flowering phenophase of winter cereals.
In contrast, scarce precipitation was observed in the wide southern areas of the Near Volga and Southern Federal Okrugs.
The Kalmykiya,Tatarstan and Bashkorstan Republics as well as the Orenburgskaya, Saratovskaya, Volgogradskaya, Tambovskaya and Astrakhanskaya Oblasts experienced a precipitation deficit, though some rainfall arrived in mid-June and partially eased the situation.
The mild weather conditions accelerated the development of winter crops by 1-2 weeks.
In the first dekad of June, winter cereals started flowering in the Black Soil Region, and have typically entered the grain-filling stage in the Southern Oblast.
Our crop simulations indicate good total and storage organ biomass accumulation in the Southern District, mainly in Rostovskaya Oblast, Krasnodarskiy and Stavropolskiy Krays.
In the Black Soil Region, biomass accumulation is near or slightly above average.
The rainfall deficiency in the Near Volga Okrug has been unfavourable for the spring crops, but soil moisture reserves have probably been sufficient to avoid significant water stress so far.
