“…Calla lily producers perform management empirically, without precise recommendations about fertilization requirements (ALMEIDA; PAIVA, 2005). The determination for the adequate supply of nutrients at each culture development stage is based on the study of growth curves and dry mass accumulation, which highlight periods and absorption rates of nutrients by plants, providing basic information about their nutritional needs (PEDROSA, 2000;MALAVOLTA, 2006, VIEIRA et al, 2008.…”

The cultivation of the calla lily, despite its importance in the floriculture sector, is still limited due to the lack of knowledge of basic production techniques such as development and dry mass accumulation. These techniques facilitate more appropriate management, especially regarding the application of fertilizers, providing better nutrients utilization and greater yields. Thus, this study was aimed at evaluating the growth and development of calla lily plants, establishing growth curves according to dry mass accumulation. Acclimatized and micropropagated calla lily plantlets were grown in plastic pots containing coconut fiber as a substrate and fertilized with a modified formula of Malavolta. Treatments consisted of assessments at intervals of 30 days for 7 months. The design was in randomized blocks with four replications, in a total of 28 plots. Plants were evaluated by observing their growth characteristics and development of shoots, rhizome, roots, as well as production and flower quality. Development of the plants increased throughout the experimental period, with the maximum dry mass accumulation occurring at the end of the experimental period. Blooming was constant with the length of flower stalks increasing with along with the age of the plant.Index terms: Zantedeschia aethiopica, floriculture, growth, production. RESUMOO cultivo de Zantedeschia aethiopica, apesar de sua importância no segmento da floricultura, ainda é limitado pelo reduzido conhecimento em técnicas básicas de produção, como o desenvolvimento e acúmulo de massa seca. Essas informações permitem um manejo mais adequado, sobretudo referente à aplicação de fertilizantes, proporcionando melhor aproveitamento de nutrientes e maiores produções. Dessa forma, neste estudo, objetivou-se avaliar o crescimento e desenvolvimento de plantas de copo-de-leite, estabelecendo curvas de crescimento, considerando o acúmulo de massa seca. Para tanto, mudas micropropagadas e aclimatizadas de copo-de-leite foram cultivadas em vasos plásticos contendo como substrato fibra de coco e adubadas com a formulação modificada de Malavolta. Foram realizadas avaliações com intervalos de 30 dias, durante 7 meses, nos quais consistiram os tratamentos. O delineamento utilizado foi em blocos casualizados, com 4 repetições, totalizando 28 parcelas. As plantas foram avaliadas quanto às características de crescimento e desenvolvimento da parte aérea, rizoma, raízes, além de produção e qualidade das inflorescências. O desenvolvimento das plantas de copo-de-leite foi crescente ao longo do período experimental, sendo que o máximo acúmulo de massa seca total ocorreu ao final do período analisado. O florescimento foi constante com aumento do comprimento das hastes florais proporcional à idade das plantas.Termos para indexação: Zantedeschia aethiopica, floricultura, crescimento, produção.

“…The curve of nutrient accumulation usually denotes fertilization according to the physiological stage of maximum absorption, so plants receive the total amount of required nutrients towards maximum production [8]. This results in lower fertilizer losses and toxicity risks [9], with no damage to the environment or the crop.…”

Amaryllis plants (Hippeastrum hybrid, in the family Amaryllidaceae) are cultivated in Brazil mainly for bulb export. Studies about the nutrient accumulation dynamics by the species are yet incipient when considering Brazilian cultivation conditions. The objective was to determine the nutrient accumulation in amaryllis "Orange Souvereign" cultivated in the field. The experimental design was entirely randomized with four replications and 14 collection periods (at 30,
