AbstractThe use of nitrogen, calcium, and boron as soil treatments influenced tropical kudzu nodulation and yields as follows: 1. Applications of nitrogen reduced nodulation per plant drastically, but increased yields significantly in the first cutting. 2. Lime increased nodulation and yields somewhat, if applied to soil the pH of which was 4.4, but when the soil pH was 5.1, the increase was barely significant. 3. When used with lime, nitrogen reduced nodulation as much as it did when used alone. 4. Boron or boron with lime had no consistent influence on yields or nodulation. 5. The protein content of the kudzu was not measurably influenced by any of the treatments as compared with the control.
