Foram formulados, caracterizados e comparados diferentes substratos orgânicos para produção de mudas de beterraba (cv. Early WonderTallTop) em bandejas de poliestro expandindo com 200 " células". O delineamento experimental utilizado foi o inteiramente casualizado, num total de 10 tratamentos com quatro repetições, sendo quatro substratos orgânicos solarizados, e dois substratos industriais. Os resultados demostram a eficácia de substratos 'a base de composto de capim Napier com estercos (bovino e de "cama" de aviário), e também de vermicomposto com casca de arroz ou de café parcialmente carbonizadas, todos suplementados com termosfato sílico-magnesiano, que promoveram desenvolvimento de mudas de beterraba superior 'aquele verificado em substratos industriais. Os orgânicos apresentam teores mais altos de N, P e K do que os industrias, além de ausência de alumínio trocável. O substrato formulado com base no processo de compostagem utilizando o esterco de " cama" de aviário, revelou maior condutividade elétrica que os demais, o que provavelmente contribuiu para a redução do desenvolvimento radicular da beterraba. A solarização inativou por completo as sementes de ervas espontâneas, predominadamente Cyperus rotundus e Digitaria sanguinalis, presentes nos substratos formulados a partir de vermicomposto. Organic substrates were characterized and compared for production of 'Early Wonder Tall Top' sugarbeet transplants in comparison to industrial substrates. The seedlings were grown in expanded poliestyrene trays with 200 'cells'. Results demonstrated the efficacy of organic substrates based on chopped Napier grass with animal manure (bovine or poultry) compost and of earthworm compost with partially burned rice or coffee grains, all supplemented with termophosphate, which promoted sugarbeet growth superior to that on industrial substrates.

This study aimed to evaluate the quality of leucaena, gliricidia, and pornunça silages with different levels of old man saltbush inclusion in their composition. A completely randomized design was used with five levels of old man saltbush (Atriplex nummularia) inclusion (0, 25, 50, 75, and 100%) in leucaena (Leucaena leucocephala), gliricidia (Gliricidia sepium), and pornunça (Manihot sp.) silages, with 5 replications per treatment, totaling 75 experimental mini-silos maintained in a covered shed and free of opportunistic animals. Silos were opened after 100 days of ensilage, and the silage of the first 15 cm of their ends was discarded. The remaining material was homogenized and sampled for determining the bromatological composition, in vitro digestibility, and fermentation profile. Old man saltbush inclusion levels in leucaena silages promoted a negative linear effect for dry matter, organic matter, crude protein, ethereal extract, pH, and ammoniacal nitrogen, while a positive linear effect was found for mineral matter, in vitro dry matter digestibility, total carbohydrates, non-fibrous carbohydrates, and propionic acid (P < 0.05). This silage also had a quadratic effect for lactic acid. Gliricidia silages showed a positive linear behavior for dry matter, mineral matter, and total carbohydrates, whereas organic matter, crude protein, and ethereal extract presented a negative linear behavior (P < 0.05). The contents of organic lactic, acetic, and propionic acids showed a quadratic effect for gliricidia silage as old man saltbush levels increased (P < 0.05). Regarding pornunça silage, dry matter, mineral matter, total carbohydrates, propionic acid, and butyric acid presented a linear increasing behavior, while organic matter, crude protein, ethereal extract, and non-fibrous carbohydrates presented a linear decreasing behavior (P < 0.05). Lactic acid and acetic acid concentrations for pornunça silage showed a quadratic behavior according to the increasing old man saltbush inclusion levels (P < 0.05). The highest contribution of old man saltbush in the silages promoted changes in the profile of organic acids, allowing an improvement in silage quality, favoring lactic fermentation rather than acetic fermentation. Butyric acid contents were low for all treatments and indicated the control of undesirable fermentation processes. These results indicate that old man saltbush inclusion in silage composition may contribute to bromatological composition and fermentation process of the studied silages.
