13. Effect of seed inoculation with Azospirillum brasilense and nitrogen fertilization rates on maize plant yield and silage quality
ABSTRACT The objective of this study was to determine the effect of Azospirillum brasilense inoculation and different nitrogen (N) rates applied as topdressing on the productivity of a maize crop and the nutritional value of maize silage. Two experiments were conducted in the 2012/2013 and 2013/2014 harvests. Treatments were distributed in a randomized block

14. Effects of lines and inoculants on nutritive value and production costs of triticale silages
ABSTRACT The current study was undertaken to investigate the ensilage characteristics in triticale lines treated by inoculants and their interaction on fermentation metabolites and rumen degradability. Costs were estimated for growing and feeding whole-crop triticale lines for animal production. Triticale hybrids were harvested at the dough stage of maturity

15. EFECTOS DEL ENRIQUECIMIENTO CON SELENIO EN SPAD, CALIDAD DE LA FRUTA Y PARÁMETROS DE CRECIMIENTO DE PLANTAS DE FRESA EN UN SISTEMA DE CULTIVO SIN SUELO
ABSTRACT Selenium (Se) is an essential trace element for animals, plants, microorganisms and human health. Thus, it appears that increasing amounts of Se in plants could have positive implications. The aim of our study was to evaluate the influence of foliar and substrate application of selenite (Se IV) and selenate (Se VI) on weight, fruit quality, growth

16. Chemical-nutritional composition of maniçoba (Manihot sp.) and its relationship with soil chemical characteristics
The objective of this study was to evaluate the chemical composition of leaves of maniçoba (Manihot sp.) according to their development stage and their relationship with the soil characteristics. For this purpose, plants in their natural growth areas in the semiarid region of Paraíba State, Brazil, were sampled. Leaves of maniçoba collected in five differ

17. Corn plant arrangement and its effect on silage quality
This experiment was carried out to evaluate the effects of the row spacing between corn plants on silage quality. Different spacing between corn rows (40, 60, and 80 cm) was used, but the population of plants was maintained around 65,000/ha in all treatments. Analysis of variance was carried out and means were compared by Tukey's test at 5% of probability. A

18. Symbiotic propagation of seedlings of Cyrtopodium glutiniferum Raddi (Orchidaceae)
In nature, orchid seeds obtain the nutrients necessary for germination by degrading intracellular fungal structures formed after colonization of the embryo by mycorrhizal fungi. Protocols for asymbiotic germination of orchid seeds typically use media with high concentrations of soluble carbohydrate and minerals. However, when reintroduced into the field, see

19. The chemical composition, fermentation profile, and microbial populations in tropical grass silages
The objective of this study was to evaluate the fermentation profile, chemical composition and microbial population and losses in the silages of signalgrass and Mombasa grass fertilized with the following levels of nitrogen (N): 0, 30, 60 and 90 kg/ha. The grasses were harvested at 70 days of regrowth, chopped and then ensiled in laboratory silos that had 20

20. Somatic embryogenesis of Neoglaziovia variegata (Arruda) Mez, an important source of fiber from native Brazilian bromeliads
Neoglaziovia variegata (Arruda) Mez, a Bromeliad endemic to the Brazilian Caatinga and source of fiber for many different products, is considered an endangered species. Leaf and stem segments were cultivated on Murashige and Skoog (MS) medium with combinations of 2,4- dichlorophenoxyacetic acid (2,4-D) (0, 9, 18 and 27 µM) and glutamine (0, 50, 100, 150, 20

21. Effect of tanniniferous plants and essential oils on methane emission in ruminants / Efeito de plantas taniníferas e óleos essenciais sobre a emissão de metano em ruminantes
Tannins and essential oils are secondary metabolites that may be used as natural modifiers of rumen fermentation to reduce the ruminants\ methane (CH4) emission. To study the application of tannin-rich plants from Egypt and Brazil, as well as essential oils that are available in international trade, three studies were conducted at Animal Nutrition Laboratory

22. Qualitative and anatomical characteristics of tree-shrub legumes in the Forest Zone in Pernambuco state, Brazil
The objective of this study was to characterize the nutritional value of forage legumes Mimosa caesalpiniifolia (Benth.), Bauhinia cheilantha (Bong.) and Leucaena leucocephala (Lan.) and evaluate the anatomy of plants incubated and not incubated in the rumen. The experiment was conducted from September 2007 to November 2008. The experimental plot consisted o

23. Forage yield and nutritive value of Tanzania grass under nitrogen supplies and plant densities
The objective of this experiment was to evaluate the nitrogen and plant density influence on the yield, forage dissection and nutritive value of Tanzania grass (Panicum maximum Jacq.). The design was of completely randomized blocks with three replications in a factorial arrangement with four nitrogen levels (0, 80, 160 or 320 kg/ha N) and three plant densiti

24. Chemical composition and photosynthetically active radiation of forage grasses under irrigation
The present study aimed to estimate the photosynthetically active radiation of tropical forage grasses in ten cutting dates, under irrigation. The following treatments were used: Brachiaria decumbens grass (Brachiaria decumbens cultivar Basilisk), Marandu grass (Brachiaria brizantha cultivar Marandu), Xaraes grass (Brachiaria brizantha, cultivar Xaraes), Mom
