Abstract
An experiment was conducted to study the effectiveness 4 foliar fertilizers (Pomior, Penshibao, Đầu Trâu và PM-6) with combination of 1/3 reduction of soil fertilizer rate for Gerbera in Hai Phong province. It was shown that foliar application with reduced soil fertilization was more efficient than normal full rate of soil application in terms of vegetative growth (leaf number, leaf area, number of young plants,...) and flower yield and quality (flowers per plant and per m2, peduncle diameter, flower diameter, flower shelf life of cut flower,...) resulting in higher economic efficacy. This indicated that foliar application was effective and positively supported soil nutrition. Among foliar fertilizers, Pomior and Đầu Trâu appeared most effective for Gerbera
