Abstract: This study addresses several questions: (1) is a soybean yield limit being reached?, (2) what is the rate of return to soybean research, and is the research effect stable over time?, (3) are technology spill-overs between states important?, (4) do input and output price fluctuations affect soybean yields?, (5) what types of weather affect soybean yields?
