Conteúdo:  A new high-yielding bermudagrass hybrid, Tifton 85, produced 26% higher DM yield (P=.05) with 11% higher IVDMD (P=.05) than Coastal in two 3-yr yield trials. Tifton 78 and Tifton 85 were established in duplicate .81-ha pastures in 1988 and were grazed during 1989, 1990, and 1991 using a variable stocking rate method. Four tester steers per pasture with 269kg initial BW grazed continuously for 169d/yr beginning in April. Forage mass, targeted at 2,800kg of DM/ha, was maintained by adjusting stocking rates at 14-d intervals to correspond with ground-levelforage samples taken at 14-d intervals. Pastures received 84kg of N/hain March, June, and August of each year. Nutritive value was assessed using whole masticate samples from two esophageal cannulated steersgrazing each pasture in late May, mid-July, or early September. The 3-yr mean masticate analyses revealed similar CP for Tifton 78 and Tifton 85 in May and July, but higher (P<.05) CP for Tifton 85 than for Tifton 78 in September. The IVDMD was higher (P<.05) in May and Septemberfor Tifton 85 than for Tifton 78; and, mean and medium particle sizes were greater (P<.05) for Tifton 85 than for Tifton 78 in May, July, and September samples. The 3-yr mean ADG was similar for Tifton 78 and Tifton 85 (.65vs .67kg; P>.10); however, grazing days/hectare were higher for Tifton 85 than for Tifton 78 (1,823vs 1,319d; P<.01). Consequently, BW gain/hectare was 46% higher for Tifton 85 than for Tifton 78 (1,156vs 789kg; P<.01). Forage qu... Mostrar Tudo

Título:  Post-emergence nicosulfuron application enhanced leaf-stem ratio in maize-intercropped with Urochloa species after shading and sunlight re-exposure.

Conteúdo:  Low rates of nicosulfuron used in post-emergence provide an advantage to maize during the coexistence of the crops, when maize is intercropped with Urochloa grasses. Nonetheless, the effect of this practice on the morphology of these grasses is not known, neither how it affects forage growth after the coexistence period nor when the grass is re-exposed to full sunlight. The aim of this study was to determine biomass and leaf-stem ratio of Urochloa hybrid cv. Mulatto II (CIAT 36087), Urochloa brizantha (Hochst. ex A. Rich.) and Urochloa ruziziensis (Germ. & Evrard) after the development in a shade simulated environment promoted by maize in intercrop systems. The treatments consisted of three brachiaria species with two herbicides managements. Evaluations occurred at 0, 30 and 60 days after the sunlight re-exposure (DASR). Nicosulfuron application and Urochloa species did not affect biomass yield. However, herbicide increased leaf-stem ratio of the species between 25% at 0 DARS to 62% at 30 DARS on old tillers (tillers that grew under shade). The biomass yield, as well the leaf-stem ratio of the new tillers was not affected. Among the species, the greater ratio of leaves in the plant biomass was recorded for Urochloa brizantha (Hochst. ex A. Rich.) and Urochloa hybrid cv. Mulatto II (CIAT 36087). Nicosulfuron use in post-emergence enhanced the leaf-stem ratio of Urochloa grasses after sunlight re-exposure and a reliable alternative to improve forage quality in intercrop system... Mostrar Tudo
