| This study was carried out to investigate the effect of extracts of leaf and roots of tough lovegrass (Eragrostis plana) on seedling growth of white clover (Trifolium repens), in two experiments. The first experiment was conducted as a pilot test, in which two concentrations (30 and 60%) of leaf aqueous extract were tested. In Experiment II, source (leaf/root) and concentration (5 and 10%) of the extracts were combined. Distilled water was used as control in both trials. Fifty seedlings at 7 days of age were placed in gerbox containers on filter paper moistened with extracts and incubated at 25°C for 14 days. In the first experiment, percentage of normal seedlings decreased by 82.5% and 100% at the concentrations of 30% and 60%, respectively, which... |

| Este trabalho foi realizado com o objetivo de comparar cultivares de Lotus spp. de diferentes hábitos de crescimento (L. corniculatus: São Gabriel - semi-ereto; ARS2620 - prostrado; L. uliginosus: cv. Maku - decumbente) cultivados em vasos e submetidos a diferentes alturas (4 - 8 cm) e freqüências (quinzenal - mensal) de corte do 95º ao 233º dia de idade. As maiores produções de massa seca (g/planta) foram obtidas com cortes mensais a 8 cm (Maku = 13,3; S. Gabriel = 11,5; ARS2620 = 7,3). Em níveis intermediários (mensal - 4 cm; quinzenal - 8 cm), o cultivar Maku foi superior aos demais, enquanto, em cortes quinzenais (4 cm), não houve diferença entre os cultivares. O cultivar ARS2620 apresentou menor estatura e maior cobertura verde residual após os... |

| This study aimed to evaluate the chemical and anatomical attributes of leaves of giant missionary grass to application of 0, 62, 124, 186, 248 and 310m³ ha-1 of pig slurry. At 83 days after the last application of fertilizer, the leaf blades were collected, fixed in FAA 70%, sectioned, stained, photographed and digitalized. The transversal section of leaf blades were evaluated for proportion of epidermis, lignified vascular tissue + sclerenchyma, non-lignified vascular tissue and parenchyma with an image-processing system calibrated to 1mm pixel-1. Leaf samples were analyzed for crude protein, acid detergent fiber, neutral detergent fiber and hemicellulose content by near infrared reflectance spectroscopy. The pig slurry application up to 310m³ ha-1... |
