| ABSTRACTThe knowledge regarding of the diaspore and post-seminal development ofPaspalum L. is important for grassland biodiversity conservation, based on their representativeness and genetic improvement of forage. The morphology of the diaspore and the post-seminal development of Paspalum dilatatum Poir. (rhizomatous),P. mandiocanum Trin. var. subaequiglume Barreto (stoloniferous), P. pumilum Nees. (decumbent caespitose) andP. urvillei Steud. (erect caespitose) was described to distinguish species with different growth forms and to survey the characters useful for taxonomy. P. dilatatum differs by presenting oval diaspores larger than the others, with five prominent nerves and trichomes; P. urvillei presents diaspores with one central nerve that is more... |

| Breeding programs for Brachiaria spp. use both intraspecies and interspecies crosses between sexual and apomictic plants in order to obtain new cultivars with the desired characteristics. As there are different ploidy levels both within and between species of this genus, it becomes necessary to evaluate the genotypes used in breeding programs, as a guide to breeders when adopting crossing strategies. In this work, DNA content and chromosome number were determined in order to characterise ploidy levels in Brachiaria spp. genotypes. In the analysis of 15 genotypes, DNA content varied with the ploidy levels (2x, 3x and 4x), and between species and/or taxon. The average DNA content was 1.74 pg (2x) in B. ruziziensis, 3.74 pg (4x) in B. decumbens and 3.52 pg... |

| Uma pastagem de Brachiaria humidicola consorciada com leguminosas foi estabelecida em uma área de "tesos" da fazenda Curral do Meio, localizada no município de Ponta de Pedras na ilha de Marajó (PA), objetivando avaliar o efeito da omissão de nutrientes sobre o estabelecimento e rendimento das plantas. O solo e um Plintossolo ácido e de baixa fertilidade natural. O clima, segundo Koppen, e Amitropical chuvoso, com precipitação pluviométrica anual media de 2.500 mm, temperatura media de 27C e umidade relativa em torno dos 85%. Utilizou-se o delineamento experimental inteiramente ao acaso com dez tratamentos e três repetições. Periodicamente, eram realizados cortes com vistas a determinação da produção de matéria seca. Os resultados obtidos indicam baixo... |

| ABSTRACT The fertilization with biofertilizer associated with the use of irrigation favors nutrient uptake by plants and soil chemical properties; however, these effects are little studied in Tithonia diversifolia in semiarid regions. This study evaluated the effect of doses of bovine biofertilizer and irrigation on accumulation of nutrients in the leaves of Tithonia diversifolia plants and on soil chemical attributes. The study was carried out from December 3, 2014 to November 28, 2015, and arranged in a 2 x 5 factorial scheme, consisting of five doses of bovine biofertilizer (0, 40, 80, 120 and 160 m3 ha-1), combined with and without irrigation. The experiment was set in a randomized block design, using three replicates. Irrigation promoted increased... |

| The use of bacterial additives in forage silages with low content of dry matter prevents undesirable fermentation and reduces losses by gases (PG) and effluents (PE) during the ensiling process. This study aimed to evaluate the fermentation parameters, chemical composition and in vitro digestibility of silage of Urochloa brizantha cv. Xaraés produced with bacterial additive. The inoculant contained the following strains: Propionibacterium acidipropionici + Lactobacillus plantarum; Lactobacillus buchnari; Propionibacterium acipropionici + commercial enzymes and Lactobacillus plantarum and Pediococcus pentosaccus, at 0, 25, 50, 75, 100, and 125% of the recommended level for sugarcane (2 g ton-1). The experiment was a completely randomized design with four... |

| This study evaluated the nutritional characteristics of BMR mutant and normal sorghum genotypes, eleven BMR mutants and nine normal. Seeds were sown in a randomized block design with three blocks, in which each genotype was a treatment. The nutritional characteristics were analyzed at 42 days of regrowth after the first cut, determined for DM, EE, ash, CP, NDIN, NIDA, NDF, ADF, NFC, CT, HCEL, CEL and NGLs. Regarding DM, EE, ash, NDIN, NIDA, NDF, FDA and HCEL, there were no differences between genotypes. As for CP, there were differences, with mean levels ranging from 9.77% for BR001AXTX2785bmr to 16.45% for BR001AxTX2784. Considering CT and NFC, there were differences in the mean levels that ranged from 75.21 to 83.28% for BR007AxTX2785bmr and... |

| Nutrition values of silages from different sorghum cultivars are evaluated. Five 26-kg castrated crossbred lambs, housed in pens equipped with feces and urine collectors for the study of their metabolism, were employed in a 5 x 5 Latin square experimental design. Treatments consisted of silage from five different sorghum cultivars: IPA 1011 and IPA 2564 (grain sorghum), IPA 2502 (dual purpose sorghum), IPA FS-25 and IPA 467 (forage sorghum). Protein level was corrected to 12% by adding a mixture of urea: ammonium sulfate (9:1). Treatments IPA 1011, IPA 2564 and IPA 2502 provided high intake of dry matter, total carbohydrate and total digestible nutrients, and low intake of neutral detergent fiber. Cultivars IPA 1011 and IPA 2564 provided high apparent... |
