Wallace became a full-time writer and editor for ''Wallace's Farmer'' after graduating from college in 1910. He was deeply interested in using mathematics and economics in agriculture and learned [[calculus]] as part of an effort to understand [[hog (swine)|hog]] prices.<ref>Culver & Hyde (2000), pp. 37–39</ref> He also wrote an influential article with pioneering statistician [[George W. Snedecor]] on computational methods for [[correlation]]s and [[regression analysis|regressions]].<ref>{{Cite journal |first1 = Henry Agard |last1 = Wallace |first2 = George Waddel |last2 = Snedecor |title = Correlation and Machine Calculation |journal = Iowa State College Bulletin |volume = 35 |year = 1925 }}</ref> After his grandfather died in 1916, Wallace and his father became the coeditors of ''Wallace's Farmer''.<ref>Culver & Hyde (2000), p. 42–44</ref> In 1921, Wallace assumed leadership of the paper after his father accepted an appointment as [[United States Secretary of Agriculture|Secretary of Agriculture]] under President [[Warren G.

In 1914, Wallace and his wife, [[Ilo Browne]], purchased a farm near [[Johnston, Iowa]]; they initially attempted to combine corn production with dairy farming, but later turned their full attention to corn.<ref>Culver & Hyde (2000), pp. 40–41</ref> Influenced by [[Edward Murray East]], Wallace focused on producing hybrid corn, developing a variety called Copper Cross. In 1923, he reached the first-ever contract for hybrid seed production, agreeing to grant the Iowa Seed Company the sole right to grow and sell Copper Cross corn.<ref>Culver & Hyde (2000), pp. 67–70</ref> In 1926, he co-founded the Hi-Bred Corn Company to develop and produce hybrid corn. It initially turned only a small profit, but eventually became a massive financial success.<ref>Culver & Hyde (2000), pp. 82–83</ref>
