13. Nitrogen fertilization on the establishment of Arachis pintoi cv. Belmonte
The objective was to evaluate the effect of nitrogen fertilization on the establishment of forage peanut (Arachis pintoi cv. Belmonte) propagated vegetatively. The experiment was conducted in a greenhouse in a completely randomized design with treatments arranged in a 2 × 4 factorial design - two ages (70 and 85 days after planting) and four nitrogen doses

14. Frequencies and intensities of defoliation in Aruana guineagrass swards: morphogenetic and structural characteristics
The objective of this study was to evaluate the morphogenetic and structural characteristics of Aruana guineagrass pastures (Panicum maximum cv. Aruana) subjected to rotational stocking by sheep. The treatments corresponded to grazing when swards reached 95 or 98% of interception of incident light (LI) until post-grazing heights of 10 and 15cm and were alloc

16. Morphogenesis in guinea grass pastures under rotational grazing strategies
This study was conducted in order to evaluate the morphogenetic and structural characteristics of guinea grass cv. Mombasa under three post-grazing heights (intense - 30 cm, lenient - 50 cm and variable - 50 in spring-summer and 30 cm in autumn-winter) when sward light interception reached 95% during regrowth. Post-grazing heights were allocated to experimen

17. Morfogênese, acúmulo de forragem e teores de nutrientes de Panicum maximum cv. Tanzânia submetido a diferentes severidades de desfolhação e fertilidades contrastantes / Morphogenesis, forage net accumulation and nutritional status of Panicum maximum cv Tanzânia under contrasting fertilization rates and grazing intensities
Nitrogen is the most important nutrient regulating pasture production. Response to N fertilization depends on residual leaf area index and other nutrient availability. The aim of this study was to evaluate morphogenetic and structural characteristics, grazing interval, forage yield and nutritional status of Tanzania guinea grass under contrasting defoliation

18. Morphogenetic and structural characteristics of tillers of guinea grass of different age and grazing severities
The objective of this research was to evaluate the effects of tiller age on morphogenic and structural characteristics of guinea grass cv. Mombaca subjected to intermittent stocking and three stubble heights: 30 cm, 50 cm and 50-30 cm. Stubble heights were assigned to experimental units in a completely randomized block design with three replicates. Grazing w

19. Morphogenesis of dwarf elephant grass clones in response to intensity and frequency of defoliation in dry and rainy seasons
The aim of this study was to evaluate during the dry and rainy seasons the morphogenesis traits of two clones of dwarf elephant grass under different management strategies. The study was conducted in a factorial 2 × 2 × 3 design, using two clones, one green and one purple, two residual heights, 25 and 45 cm, and three frequencies of defoliation according t

22. DEVELOPMENT, GROWTH, AND YIELD OF CASSAVA AS A FUNCTION OF PLANTING DATE / DESENVOLVIMENTO, CRESCIMENTO E PRODUTIVIDADE DA MANDIOCA EM FUNÇÃO DE DATAS DE PLANTIO
Cassava (Manihot esculenta Crantz) is a native plant of Brazil and the base of multiple products, iincluding ethanol. Rio Grande do Sul State is a minor producer of cassava in Brazil, especially in the Central Region of the State. The objective of Chapter I in this Dissertation was to determine the phyllochron, the final leaf number (FLN) on the main stem (M

24. Características morfogênicas e estruturais de faixas etárias de perfilhos em pastos de capim-marandu submetidos à lotação contínua e ritmos morfogênicos contrastantes / Abstract Morphogenetic and structural characteristics of tiller age categories on continuously stocked marandu palisadegrass swards subjected to contrasting morphogenetic rhythms
Recently, studies focusing on morphogenetic and structural characteristics have become increasingly important since they facilitate the understanding of forage plants when subjected to grazing. Quite often nitrogen fertilisation is used as a means of increasing growth rhythm of plants that, because of the turnover in tiller population, may result in signific
