Russia. July’s weather conditions were controversial for grain filling

11.08.2017

In the Central, North-Western and Volga federal districts, July’s weather was variable, with frequent rainfalls, which were heavy in some areas. Hail occurred in a number of areas that locally damaged crops. Some points in the above districts received a total of 150 to 200 mm of precipitation in July, or 1.5-2 times the normal rates for this month. Lodging of tall cereals was locally observed in these areas. Rains, high air humidity and below-normal temperatures slowed down ripening of winter cereals. The conditions for flowering and pollination of early spring cereals deteriorated in some areas. This may have an adverse impact on ear grain content.

July’s precipitation rates in the south of the Central federal district and south-easternmost parts of the Volga district were mostly below normal. In the above areas, winter crops (as well as spring barley in some fields) reached full maturity on July 11-20, i.e. almost two weeks later than in 2016.

It was mostly warmer than usual in the Southern and North Caucasian federal districts in July. Winter cereals and early-sown spring barley reached full maturity toward July 10 (i.e. close to the long-term average time but 10-12 days later than last year). In July, most areas received less precipitation than usual. In addition, its distribution was extremely uneven. The weather conditions were mainly favorable for harvesting. Weight of harvested grain was close to usual in most areas. It was only below normal in some north-eastern areas of Stavropol region and the Republic of Dagestan. Up to 15-30% of shriveled kernels were locally registered there. In many areas, moisture supply for late arable crops decreased to fair, even to poor levels in some fields. The reason is precipitation shortages in the latter half of July.

Corn was at milky and wax ripeness in most fields, though grain filling and tasseling/silking continued in part of areas. Seed filling and ripening continued in sunflower plants; late-sown ones were even in bloom. In isolated fields exposed to soil moisture shortages, the hot weather caused leaf turgor loss in the daytime, as well as premature yellowing and drying of lower layer leaves. The conditions got worse for cob formation and grain filling in corn. The agrometeorological conditions were only alleviated by rainfalls that occurred in some areas in the last couple days of July.
