摘要
different organic fertilizers were compared with the traditional chemical fertilization of the yellow passion fruit plant in northern rio de janeiro state, brazil, in terms of the effects on yield, number, and mean weight of fruits. the experiment was carried out in the municipal district of campos dos goytacazes, rio de janeiro state, from february 2005 to july 2006, in a randomized blocks design with four replications and six treatments, corresponding to the following dosages of fertilizer per plant: aq - 100 g of chemical fertilizer (20% n - 5% p2o5 - 20% k2o) + mulching (cm); rm - 5 l of cassava abrades + cm; eb - 5 l of cattle manure + cm; tf + cm - 5 l of sugar cane plant filter pie + cm; foc - 500 g of bone and meat meal + cm; tf - 5 l of sugar cane filter pie without cm. the bone and meat meal and sugar cane filter pie treatments, with and without mulch, did not differ from chemical fertilization in terms of yield, number, and mean weight of fruits. they can be used in replacement for chemical fertilization.
