“…Estes resultados são compatíveis e superiores aos relatados por Fiorini et al (2016) em estudo realizado neste mesmo município no período de primavera. Estes autores relataram para a cultivar Grand Rapids valores de BFC igual a 176,59 g planta -1 , enquanto que para a cultivar Elisa, os valores foram de 140,74 g planta -1 .…”

O objetivo do presente trabalho foi avaliar o efeito da aplicação de bokashi, esterco bovino, e da combinação entre estes, sobre o crescimento e produtividade de nove cultivares de alface (Lactuca sativa L.) nas condições de Seropédica-RJ. O ensaio foi realizado em condições de campo no período de setembro a outubro de 2017. Utilizaram-se como tratamentos quatro tipos de adubação, sendo: bokashi (0,5 kg/m2); mistura de bokashi com esterco bovino (0,250 kg/m2 +1,0 kg/m2, respectivamente); adubação com esterco bovino (2,0 kg/m2) e testemunha, em combinação com nove cultivares de alface (Babá de Verão, Elisa, Mimosa, Grande Rapids, Camila, Sabrina, Grande Lagos, Regina, e Quatro Estações). O delineamento experimental adotado foi blocos ao acaso em esquema de parcelas subdividas, sendo, as diferentes fontes de adubação (parcelas) e cultivares (subparcelas), com quatro repetições. Avaliaram-se o diâmetro da cabeça (cm), biomassa fresca da cabeça (g planta-1), número de folhas e produtividade estimada (ton.ha-1). Não houve efeito significativo da interação adubação x cultivar sobre as variáveis analisadas. As cultivares Grandes Lagos e Grandes Rapids apresentaram maior produção de biomassa fresca da cabeça e produtividade que as demais. A alface respondeu positivamente a adubação orgânica e o composto bokashi foi o que proporcionou melhores ganhos em crescimento e produtividade para a cultura. A utilização de esterco bovino também produziu bons resultados no desempenho da cultura representando mais uma possibilidade a ser utilizada pelo produtor.

“…The roselle (Hibiscus sabdariffa) was cultivated between the months of May and September in a Planosol in the Horticulture sector from the Federal Rural University of Rio de Janeiro -UFRRJ, in Seropédica -RJ, whose geographic coordinates are 22°44'38" S , 43º42'28'' W, at an altitude of 26 m and with the region climate being the Aw type, from the Köppen classification, with rainy summers and high temperatures, and between April and September the climate is milder and dry (Fiorini et al, 2016).…”

FOOD SCIENCE (CIÊNCIA DE ALIMENTOS) ABSTRACT: "Vinagreira" (Hibiscus sabdariffa) is an unconventional species with multiple possibilities of use, with food and industrialist potential. The objective of this work was to quantify some of its constituents and to evaluate the effect of the packaging on its post-harvest conservation. Branches were transported at Universidade Federal Rural do Rio de Janeiro campus and to Embrapa Agroindústria de Alimentos, where they were packed in polypropylene (perforated, micro perforated and unperforated) conical packages, except for the control and stored at 5 ± 1 °C and 75% relative moisture. Before storage were evaluated: organic acids, carotenoids, total phenol, antioxidant activity, pH, titratable acidity, soluble solids and fresh mass. The fresh mass loss, titratable acidity and soluble solids were analyzed every two days of storage. The design was completely randomized, in split plots. "Roselle" leaves may be considered sources, specially β-carotene (28.49 µg g-1) and lutein (25.70 µg g-1). The use of polypropylene packages in combination with refrigeration allowed for greater storage, with increase up to four days in the "vinagreira" shelf life, being the best results for unperforated packages were relatively better during storage.

“…In line with these findings, Maia et al ( 2008) observed positive outcomes concerning this variable while evaluating the impact of biofertilizers prepared with nursery water. Similarly, Fiorini et al (2016) demonstrated significant results when assessing cultivars across two seasons under organic management in Baixada Fluminense, highlighting the seasonal influence on the development of plant head diameter (PHD).…”

This study aimed to explore the efficacy of utilizing wastewater from fish farming tanks for fertigating lettuce crops as an alternative to inappropriate disposal methods. A randomized block experimental design was employed in a 3 x 8 factorial scheme, comprising three treatments: two varying percentages of wastewater (50% and 100%), alongside a control treatment employing only well water, with eight replications each. The trial was conducted in a field under protected cultivation, within a low tunnel-type structure. Biometric parameters of the lettuce plants were analyzed, including stem diameter, plant height, stem length, head diameter, root length, leaf fresh matter, leaf dry matter, stem fresh matter, stem dry matter, root fresh matter, root dry matter, leaf count, fresh shoot mass, and commercial productivity. Significant results were observed with the application of 100% wastewater treatment up to 20 days after transplanting (DAT), particularly for the biometric variables: plant head diameter (average 37.4 cm) and leaf count (average 13.7 units) at 36 DAT, of crisp lettuce Grand Rapids loose leaf seedlings. The reuse of wastewater during the experiment showed promising potential in replacing chemical fertilizers throughout the crop cycle. This practice facilitates the repurposing of water from fish farming, providing farmers with an alternative income source during the fish development phase, and mitigates improper wastewater disposal.
