“…A literatura reporta sobre o desenvolvimento de plantas de pimentão, obtendo-se plantas com alturas variando de 50 a 200 cm, dependendo do material genético, condições ambientais, ciclo da cultura e práticas de manejo de culturas aplicados na cultura (Fontes et al, 2005;Charlo et al, 2011).…”

RESUMOEste trabalho foi desenvolvido com o objetivo de se avaliar os efeitos de manejos de fertirrigação e níveis de nitrogênio e potássio sobre o crescimento e a produção de pimentão cultivado em ambiente protegido. Utilizou-se o delineamento em blocos casualizados com 18 tratamentos e quatro repetições. Os tratamentos resultaram da combinação de três manejos da fertirrigação e com seis doses de nitrogênio e potássio. Foram realizadas seis colheitas e, nelas, avaliações quanto ao número, massa média e produção de frutos além de indicadores de crescimento (área foliar, altura e acúmulo de fitomassa). Os resultados obtidos demonstram que o crescimento e o rendimento do pimentão dependem, além das doses de N e K, do manejo de fertirrigação adotado. O manejo da fertirrigação a partir do monitoramento da concentração de íons de N e K com auxílio dos extratores de solução, ou da condutividade elétrica da solução do solo é mais eficiente que o manejo tradicional. O monitoramento da solução do solo deve ser realizado utilizando-se, como referência, as concentrações variando de 200 e 250% de N e K correspondentes à recomendação para a cultura do pimentão em sistema hidropônico.

The experimental design was in a completely randomized block, with 18 treatments and four replications. Treatments resulted from the combination of three fertigation managements and six nitrogen and potassium doses. There were six harvests, when evaluations were made of fruit number, mean mass and yield, as well as of growth indicators (leaf area, plant height and dry mass). Results showed that, besides the N and K doses, bell pepper growth and yield also depend on the management of fertigation used. Fertigation managements based on concentration of N and K ions using solution extractors, and monitoring of soil electrical conductivity were better than the usual management. Soil solution monitoring must take as reference N and K concentrations between 200 and 250% of recommendation for bell pepper production in hydroponic system.

“…At 189 DAT, there was an accumulation of 2.25 g plant -1 , where 130.16 days after transplanting were needed for an accumulation of 50% of this amount. This means that a greater demand for this nutrient occurs during the fruiting phase, because the physiological activity of the plant is greater, as can be seen by the accumulation of dry mass in the research of Charlo et al (2011). The mature fruits, stem and leaves were the organs that accumulated the most sulfur, with respective amounts of 1.03, 0.54 and 0.49 g plant -1 .…”

The production of sweet peppers in greenhouse has been severely affected by soil pathogens. With this, producers are adopting new cultivation techniques, such as cultivation in substrates, but information about this type of cultivation are still scarce. The aim of the present work was to evaluate nutrient accumulation in sweet peppers cultivated in coconut fiber with fertirrigation in greenhouse. Initially, 160 plants (Eppo cultivar) were divided into four blocks, where two plants per block were analyzed every 21 days after transplanting. The sweet peppers were cultivated in plastic pots of 13 L, containing coconut fiber, and placed in double rows with spacing of 0.5 x 0.8 m between single rows and 1.10 m between double rows. The commercial production of the mature fruits was estimated to be 97.3 t ha -1, where all the production was classified as Extra (maximum quality). The accumulation of the various determined nutrients were: 8.22 g plant -1 of N, 1.14 g plant -1 of P, 7.84 g plant -1 of K, 3.25 g plant -1 of Ca, 1.34 g plant -1 of Mg, 2.24 g plant -1 of S, 16.65 mg plant -1 of B, 3.36 mg plant -1 of Cu, 45.98 mg plant -1 of Fe, 34.78 mg plant -1 of Mn and 22.28 mg plant -1 of Zn.

Knowledge of the nutrient uptake by crops at different stages of growth may provide the basis for rational application of fertilizers, which may lead to reduced production costs and improved use of fertilizers by plants. Based on this knowledge, we conducted this study to determine the biomass and nutrient accumulation curve of the onion cultivar Bella Vista in a system of transplanted seedlings. The experiment was carried out in Ituporanga-SC, Brazil, by using a randomized block design with three replicates. Eleven plant collections were carried out throughout the crop cycle. The variables evaluated included plant length; total dry biomass of leaves, bulbs, and roots; and concentrations of macro- and micronutrients. The maximum dry biomass accumulation in the shoots and bulbs at 140 days after transplanting (DAT) was 4.26 and 27.41 mg per plant, respectively, which contributed to 13% and 85% of the whole plant dry biomass at the end of the cycle, respectively. Potassium (K, 521.6 mg) was accumulated in the largest quantity per plant, followed by nitrogen (N, 465.7 mg), calcium (Ca, 253.3 mg), sulfur (S, 109.0 mg), magnesium (Mg, 86.9 mg), and phosphorus (P, 76.5 mg). The micronutrient accumulation was as follows: iron (Fe, 6,227.5 µg), boron (B, 902.3 µg), zinc (Zn, 573.7 µg), manganese (Mn, 573.7 µg), and copper (Cu, 241.4 µg).
