rates were 240 kg·ha −1 N, 34 kg·ha −1 P, and 128 kg·ha −1 K, which were recommended fertilization rates for intermediate-day onion in Korea. The N rates were 0, 120, 240, and 360 kg·ha −1 N applied as urea. The P rates were 0, 18, 35, and 52 kg

N had higher yields than unfertilized controls ( Hanson and Retamales, 1992 ). In contrast, Clark et al. (1998) found that yield of ‘Collins’ blueberry was unaffected by fertilization rates of 22 and 112 kg·ha −1 of N, and in fact, applications of
