Answer
Vernalization, the agricultural technique falsely championed by Trofim Lysenko, involved exposing seeds to low temperatures before planting to enhance crop yield. Despite lacking scientific evidence, Lysenko's influence in Soviet agricultural policies during the mid-20th century led to the widespread adoption of vernalization, resulting in devastating crop failures and famines. This erroneous practice exemplifies the detrimental consequences of disregarding scientific principles in favor of ideological biases in agricultural practices.
