ABSTRACT: Different Levels of Water Necessity Applications Using Wastewaterand Organic Manure on Growth and Development of Chrysanthemum. Nowadaysthe floriculture is in full expansion in Brazil, and may be considered the most lucrativebranch of agriculture. In this activity, the crop of cut flowers is oen of the mostimportant and the chrysanthemum disputes with the roses ranking of the most soldflowers. The tests of use of domestic wastewater in cut flowers growing are valid,because it does not generate an eatable product, mainly for the regions similar to theBrazilian northeast, devoid of water. Other resource recycling in agriculture is the use oforganic manures, which may improve also chemical and physical properties of the soiland the production. This work had as objective to study the effect of the irrigation withdifferent levels of application of wastewater necessity and the use of organic manure inthe growth and development of chrysanthemum. The experiment was carried out undergreenhouse at the UFCG. The experimental design was in randomized blocks in afactorial scheme of 4 x 2 + 2, with 4 repetitions, tested 4 levels of wastewater necessityreplacement (100, 80, 60 and 40%) in combination with 2 organic manuring rates -absence and presence of cattle manure, with 2 controls (plants irrigated with supplywater at 100% of the water necessity under organic and mineral fertilization,separately). The highest growth phase in terms of plant height, lateral shoot and numberof leaves occurred on 38, 59 and 17 days after transplanting, respectively, obtainingbetter results under wastewater use, specially with the 80% reposition. The mineralfertilizing was better than the organic one in all analyzed variables.Key-words: wastewater, cut flower, cattle manure.INTRODUÇÃODentre os segmentos produtivos agroindustriais de destaque nos cenários nacional einternacional, a floricultura mostra-se como um dos mais dinâmicos e promissores (Fernandeset al., 2007). No Brasil o setor da floricultura aparece como uma das melhores alternativaspara quem busca investimento na agricultura. Isso porque demanda pouca área e o ciclo deprodução, dependendo da cultura, é geralmente curto, o que permite giro rápido do capital(Matsunaga, 1995).A distribuição da área cultivada, em 2006, com flores e plantas ornamentais era de50,4% para mudas; 13,2% para flores envasadas; 28,8% para flores de corte; 3,1% parafolhagens em vasos; 2,6% para folhagens de corte e 1,9% para outros produtos dafloricultura.Como planta ornamental de grande destaque o cultivo do crisântemo em 2003, noestado de São Paulo, líder em floricultura no território nacional, se destacava comosegunda espécie mais plantada em área no estado, 430 ha, representando mais de 12%de toda a área ocupada com cultivo de flores, perdendo somente para a cultura de rosasque ocupava 984 ha, aproximadamente 28% da área total de cultivo (Francisco et al.,2003).Outro dado interessante e que dentre as plantas mais vendidas nos três maioresmercados nacionais, o crisântemo encontra-se em posição de destaque,:como terceiro127
