Abstract
In a 3-year field study the average yield of pods at green-shell maturity of the ‘Princess Anne’ variety of blackeye pea was 74% higher in 6-inch drilled rows than in 36-inch rows. Fertilizer applications did not influence yields in plots at various row spacings on a Woodstown sandy loam soil testing very high in P and high in K. Nor was there a significant interaction between spacing and fertilization.
Abstract
In a basic fertility study with the ‘Princess Anne’ a black-eye variety of southern peas, utilizing a Woodstown sandy loam soil in terra cotta tiles under outside field conditions, an application of 30 lb. N/A increased the yield of pods at green shell maturity in 1 out of 2 years. Yields increased both years with increasing rate of P application up to and including 200 lb. P/A. Applied K did not increase yields when the soil tested medium or high in available K.
Highly significant increases in plant growth resulted from increasing rates of P application, but plant growth was not appreciably affected by applied N and K. The plant content of P and K increased with the application of each respective element; however, the application of P resulted in a reduction in the level of K in the plants. Applied N did not materially influence the level of N in the plants but did increase the plant content of Ca and Mg; whereas applied K reduced the level of Ca and Mg in the plant.
