During the past year I conducted three field trials in lettuce and gathered data from five tomato field trials. The three lettuce trials used physical plant markers. Three of the tomato trials had physical markers while two had topical markers. I collected weed density counts before and after cultivation, plant stand counts, time to hand-weed after mechanical cultivation, and marketable yields.

Though IAD students tend to travel to other parts of the world for their research, my project has kept me very close to home: I have been developing curriculum for a Practicum in Beekeeping course that was offered here at UC Davis during Fall Quarter 2018. With support from Jastro, I was able to purchase the equipment and resources I needed to attend trainings and gain the experience needed to effectively design the course.

Ethanol made from cassava root had long been a dream of UC Davis Humphry fellow and Sierra Leonean native Martin Kailie, with whom I worked to execute this study.

The Amazon rainforest is the largest tropical rainforest in the world but human activity like cattle ranching, illegal logging, and large-scale monoculture soy and corn production have been driving deforestation.
