摘要: Abstract Concern over the pollution potential of nitrogen (N) fertilisers has prompted studies utilisation efficiency applied N by crops. This study was conducted to determine usage bell pepper (Capsicum annuum L.) grown with plastic mulch and trickle irrigation, define a rate which is equal uptake crop. The relationships between (0, 70, 140, 210, 280 kg/ha), nutrient uptake, yield for spring autumn crops on major soil type (Tropeptic Eutrustox) in Bundaberg region subtropical Australia were investigated. Maximum dry weight fruit, leaves, roots, stems corresponded N210 N280 both In addition, maximum fresh marketable fruit seasons. Nitrogen at N140. Plant elements increased and, N280, ranked as follows: K> N> Ca> Mg > S P. Frui...
