2. FUZZY MODELING ON WHEAT PRODUCTIVITY UNDER DIFFERENT DOSES OF SLUDGE AND SEWAGE EFFLUENT
ABSTRACT: This study aimed to evaluate the effects of fertilization with composted sewage sludge and irrigation with drinking water (DW) and fertigation with wastewater (WW) in wheat crop using fuzzy rule-based system. The experiment was conducted in the Department of Soil and Environmental Resources, of FCA, UNESP - Botucatu, with factorial 6 × 2, which we

3. Piata palisade grass deferred with two distinct initial heights: luminous environment and tillering dynamics
The study was carried out between March 1st and July 1st, 2011, in order to evaluate the tillering pattern of the deferred Piata palisade grass (Brachiaria brizantha cv. Piata). Three sward heights were evaluated in the beginning of the period of deferment: lower (20 cm), medium (30 cm) and higher (40 cm). The experimental design was of completely randomized

4. Morphogenesis of Tanzania guinea grass under nitrogen doses and plant densities
The objective of this work was to evaluate effects of nitrogen fertilization and plant density on morphogenesis of Tanzania guinea grass. It was used a random block design with 12 treatments and two replications in a 4 × 3 factorial arrangement, with four doses of nitrogen (N) (without N application, 80, 160 or 320 kg/ha.year) and three plant densities (9,

5. Dinâmica do perfilhamento em capim-elefante sob influência da altura do resíduo pós-pastejo.
O objetivo deste trabalho foi avaliar o efeito de duas alturas do resíduo pós-pastejo (50 e 100 cm) sobre a dinâmica do perfilhamento, a massa de matéria seca por perfilho e o acúmulo de matéria seca de forragem de perfilhos basais e aéreos, em pastagens de capim-elefante. Foi utilizado o delineamento de blocos ao acaso, em arranjo de parcelas subdivi

6. Avaliação de clones de capim-elefante manejados sob lotação rotacionada. / Evaluation of clones of elephant grass managed under rotational stocking.
This work aimed to describe and evaluate the morphogenetic and structural traits, and quality of two clones of elephant grass grazed under rotacional grazing. We used a completely randomized design with three replicates (paddocks) in a split plot, where clones were the whole plot and grazing cycles in a split plot, for evaluate morphogenetic and structural t

7. Demografia do perfilhamento e produção de forragem em pastos de capim-marandu submetidos a regimes de lotação intermitente por bovinos de corte / Tiller demography, tillering dynamics and growth of marandu palisadegrass swards subjected to strategies of rotational stocking
Tillering plays a central role in the recovery of sward leaf area and growth patterns of forage plants, influencing pasture longevity and productivity. However, little is known about the tillering process in tropical grasses, particularly Brachiaria brizantha cv. Marandu (marandu palisadegrass), one of the most used species on cultivated grassland areas in B

8. Caracterização morfogênica de gramíneas forrageiras tropicais sob crescimento livre / Morphogenetic charaterization of tropical forage grasses under free growth
In this work, the morphogenetic and structural characteristics of tropical grasses were evaluated in a comparative way, aiming their insertion in the respective functional groups, supplying subsidies to researchers in the implementation of grazing experiments suitable with their growth pattern and development. The experiment was conducted in the Forage Cultu

9. Avaliação agronômica da cana-de-açúcar submetida a métodos de colheita para produção animal / Agronomic traits of sugarcane (Saccharum spp.) under different harvesting methods for animal production
This research aimed to study harvesting losses, morphologic composition, dynamics of tillering and accumulation and, tiller density of sugarcane IAC86-2480 variety under three harvesting methods. In manual harvesting (MAN), plants were harvested to ground level, using a cutter. For mechanical harvesting (MEC), the harvester (adjusted for 20 cm from the groun

12. Weight gain and morphogenic characteristics of forage plants on Cameroon grass and braquiarÃo grass pastures under different stocking rates / Ganho de peso e caracterÃsticas morfogÃnicas das forrageiras em pastagens de capim-cameroon e capim-branquiarÃo sob diferentes taxas de lotaÃÃo
The scope of this work was to evaluate on pastures formed of P. purpureum cv. Cameroon and B. brizantha cv. Marandu submitted to four stocking rates, the population dynamics of tillers and tissue turnover, aiming at increased availability of forage and animal yield. Two experiments were conducted at the Experiment Station of Animal Science of the Extreme Sou
