The identification of appropriate nitrogen (N) rates for native warm-season grasses (NWSG) is needed to inform forage management in the southeastern United States. Experiments were conducted Knoxville and Springfield, TN, from 2015 2019, evaluate dry matter (DM) yield, nutritive value (FNV), influence temperature precipitation on partial factor productivity (PFP) responses. Three NWSG species (big bluestem [BB; Andropogon gerardii Vitman], switchgrass [SG; Panicum virgatum L.], eastern...
Data are needed to identify optimum response potassium (K) and phosphorus (P) amendment associated mycorrhizal colonization for native warm-season grasses (NWSGs; big bluestem [BB; Andropogon gerardii Vitman] switchgrass [SG; Panicum virgatum L.]). To evaluate these responses, experiments were conducted in Knoxville Springfield, Tennessee, from 2013 2019. In twice-annual harvests, we assessed BB SG dry matter (DM) yield, crude protein (CP), total digestible nutrients (TDNs), P K removed by...
Reduced floral resources and habitat fragmentation have led to pollinator decline. Increased diversity of native plants in pastures could support cattle pollinators. However, the relationship between grazing plant needs be investigated. We explored how rest periods impacted persistence forage characteristics Andropogon gerardii (BB)/Sorghastrum nutans (IG; BBIG) Panicum virgatum (SG) interseeded with forbs grazed over five years. ANOVA analysis was conducted using R significance set at p ≤...
Pollinator declines and expectations for more sustainable agriculture, including pasture-based enterprises, bring attention to strategies enhance the habitat value of grazing lands. We evaluated native warm-season grass (NWSG) pastures with (FORB) without (CONT) interseeded forbs in 2021–2023. An analysis was conducted using R significance set at p ≤ 0.05. The appeared be weakened predominantly by management practices. Forb density mass had an inverse relationship seasons two three. Total...
Conservation agriculture technologies are promoted in sub-Saharan Africa to conserve water, reduce soil erosion, increase farmer household well-being and crop yields, achieve food security. However, conservation adoption rates by smallholder farmers this region remain relatively slow. This paper examines the factors influencing of two important components Lesotho—minimum disturbance residue retention—and effects these have on input demand, maize (<i>Zea mays</i> L.) production, farm profit...
Insect pollinators are in population decline due to environmental and chemical stressors. Including native forbs pastures could benefit grazers pollinators; however, their forage flowering characteristics not fully documented. The objectives of our research were evaluate 12 for persistence, mass, nutrient composition, patterns under repeated defoliation. Twelve species planted a small-plot experiment 2018. Response variables measured from 2020 2022. Annual (partridge pea, PPEA, Chamaecrista...
