Lucia Victoria Chigamane’s interest in agriculture began on her mother’s small farm, close to the city. “I went there on weekends with my mother and siblings. My mother, a woman with keen attention to detail, would ask why some of our maize fields required more fertilizer than others,” she says. I noticed that our maize yields, although relatively higher than our neighbors’, were less than the projected yields on the fertilizer packaging, and I wanted to know why.
