Low harvest

According to historian Stephen G. Wheatcroft, the grain yield for the Soviet Union preceding the famine was a low harvest of between 55 and 60 million tons, likely in part caused by damp weather and low traction power, yet official statistics mistakenly reported a yield of 68.9 million tons. (Note that a single ton of grain is enough to feed three people for one year.) Historian Mark Tauger has suggested that drought and damp weather were causes of the low harvest. Mark Tauger suggested that heavy rains would help the harvest while Stephen Wheatcroft suggested it would hurt it which Natalya Naumenko notes as a disagreement in scholarship. Another factor which reduced the harvest suggested by Tauger included endemic plant rust. However, in regard to plant disease Stephen Wheatcroft notes that the Soviet extension of sown area combined with lack of crop rotation may have exacerbated the problem, which Tauger also acknowledges in regard to the latter.
