... The objective of this study was to evaluate the effects of different crop arrangements and weed management in integrated crop–forage–forestry systems on weed incidence, yield of maize and forage grass, quality of total harvested and tree development. The experiment was analyzed as split-plot and as randomized complete block design. Whole plots were crop arrangements containing maize, Marandu palis ...

Abstract:
... Urochloa hybrids produce large amounts of biomass and have drought tolerance; however, there are few reports on the forage yield and quality of these forage grasses in semi‐arid environments. We evaluated the forage yield and nutritional value of Urochloa hybrids (‘Mulato II’, ‘Cayman’ and ‘Cobra’) and Pennisetum ciliare ‘H‐17’ (control) at three regrowth ages (RA: 4, 6 and 8 weeks), at maximum (M ...

Abstract:
... Perennial ryegrass (Lolium perenne L.) is one of the most important forage grass species in temperate regions of Australia and New Zealand. However, it can have poor persistence due to a low tolerance to both abiotic and biotic stresses. A major challenge in measuring persistence in pasture breeding is that the assessment of pasture survival depends on ranking populations based on manual ground co ...

Abstract:
... Seeding is sometimes used in attempts to increase grass forage production in invaded rangelands, but insufficient long-term data prevent determining if seeded grasses are likely to become and remain productive enough to justify this expensive practice. We quantified long-term seeding outcomes in a widespread Rocky Mountain foothill habitat invaded by leafy spurge (Euphorbia esula L.) and several e ...
