摘要:
A field experiment was conducted on a Bradson gravelly loam (clayey, oxidic, mesic Typic Hapludult) at Fletcher, North Carolina, to determine the effect of timing and rate of N and rate of P and K fertilization on snap bean yield and grade, plant tissue nutrient concentrations, and residual soil test levels. Fertilizer treatments were arranged according to a sequential one‐factor‐at‐a‐time design and established as randomized blocks. Initial soil test levels by the Mehlich‐I extractant were 4 μg P/cc (very low) and 0.09 meq K/100 cc (low).
