Populational density and harvest age of carrots for baby carrot manufacture
Provedor de dados: Horticultura Brasileira
Autores: Simões,Adriano do N; Moreira,Silvino I; Costa,Franciscleudo B da; Almeida,Alysson Roberto de; Santos,Ricardo HS; Puschmann,Rolf.
The quality of baby carrots may be associated to the standard of the raw material that in turn, may be influenced by agronomic practices. Thus, the effect of planting density and harvest age were assessed on physical and morphological characteristics, yield and end quality of intact and minimally processed carrots in the form of baby carrots. A randomized block experimental design was used with the density in the plots (4 x 20 cm and 4 x 7.5 cm) and the harvest age in the subplots (50, 57, 64, 71, 78, 85, 92, 99 and 106 days), with five replications. The experimental unit consisted of 25 plants. The assessments of diameter, length, yield, secondary phloem translocation with the cambio and total carotenoids were decisive in selecting the carrot harvest age...

Levels of Crotalaria juncea on growth, production, recovery and efficiency of the use of N in broccoli
Provedor de dados: Horticultura Brasileira

ABSTRACT The recommendation for green manure (GM) in cropping systems still has little scientific support, with few studies addressing the effects of nutrient amounts from green manure on the growth and production of the crop. Our aim was to evaluate the effect of levels of Crotalaria juncea green manure on the growth, production, and efficiency of the use as well as the apparent recovery of N in broccoli crop. Seven treatments were established; the main with four doses of green manure: 0, 3, 6, and 9 t/ha on a dry matter (DM) basis, applied with 12 t/ha compost. The control treatments consisted of mineral fertilization, the treatment with 25 t/ha compost, and another as the absolute control. Comparatively, production under the absolute control was less...

Balanço e análise da sustentabilidade energética na produção orgânica de hortaliças
Provedor de dados: Horticultura Brasileira
Autores: Souza,Jacimar Luiz de; Casali,Vicente Wagner D; Santos,Ricardo HS; Cecon,Paulo R.
Os insumos e serviços utilizados na produção vegetal representam custo energético. Dependendo desses fatores e das produtividades obtidas, a conversão da produção em energia determinará a eficiência energética do sistema. A agricultura orgânica somente atingirá a missão de preservação ambiental se tiver comprovada sustentabilidade energética. Neste trabalho, objetivou-se caracterizar os balanços energéticos dos cultivos orgânicos e analisar sua sustentabilidade, em comparação aos sistemas convencionais. Monitoraram-se campos de produção de dez culturas, de 1991 a 2000 em Domingos Martins-ES. Os dados do sistema convencional foram obtidos pelas médias dos coeficientes técnicos da região. Quantificaram-se os coeficientes técnicos, convertendo suas grandezas...

Chemical composition, carotenoids, vitamins and minerals in wild mustard collected in native areas
Provedor de dados: Horticultura Brasileira
Autores: Paula Filho,Galdino X; Barreira,Tibério F; Santos,Ricardo HS; Priore,Silvia E; Lucia,Ceres M Della; Pinheiro-Sant’Ana,Helena M.
ABSTRACT Wild mustard plant (Sinapis arvensis), Brassicaceae, is a wild vegetable found in forest area, domestic orchards and it is consumed by rural population. This study aimed to evaluate chemical composition (moisture, total dietary fiber, lipids, proteins, ash, carbohydrates and total energetic value), concentration of carotenoids, vitamins (C and E) and minerals (K, Ca, Mg, Cu, Fe, Zn, Mn, Na, Cr, Se and Mo) and the contribution by this vegetable to the recommendations of daily consumption of nutrients for adult individuals. Concentrations of provitamin A (252.21 RAE/100 g), Se (0.04 mg/100 g) and Fe (5.91 mg/100 g) stood out, in which this vegetable was considered as an excellent source for these nutrients. In addition, wild mustard was considered a...
