Abstract
SUMMARY An experiment examining the main and interactive effects of vegetative (i.e., sprout) year applications of nitrogen, phosphorus, and potassium fertilizers was conducted at two commercial wild blueberry fields near Kemptown, Nova Scotia and Mount Vernon, Prince Edward Island during 2000 and 2001. The nitrogen (N), phosphorus (P), and potassium (K) sources consisted of urea (N at 0 to 60 kg-ha−1), triple superphosphate (P2O5 at 0 to 150 kg-ha−1), and potash (K2O at 0 to 60 kg-ha−1). A completely randomized rotatable composite design was used with 16 treatments, 4 replications, a plot size of 6 m × 8 m, and 2 m buffers between plots. Overall, leaf tissue N, P, and K levels were increased at both sites with fertilizer applications. Main and interactive effects of the soil applied N, P, and K on stem length, individual stem dry weight, and stem density were also present at both sites. Significant effects of soil-applied N and K, and soil applied K on fruit set were present at the Kemptown and Mount Ver...
