Defoliation intensity and simulated grazing strategy effects on three C4 rangeland bunchgrasses
(2018-01)
Defoliation intensity and timing are two important factors determining plants response to grazing. These factors can be managed by adjusting stocking rate and applying a grazing strategy. In a 6-yr clipping experiment ...
Effects of defoliation frequency and nitrogen fertilization on the production and potential for persistence of Dactylis glomerata sown in multispecies swards
(Wiley Blackwell Publishing, Inc, 2017-09)
Management decisions should facilitate the dominance of C3 perennial grasses over annuals. This study examined the effects of defoliation frequencies and nitrogen fertilization on the productivity and potential for persistence ...
Detection of defoliation injury in peanut with hyperspectral proximal remote sensing
(2020-11-02)
Remote sensing can be applied to optimize efficiency in pest detection, as an insect sampling tool. This efficiency can result in more precise recommendations for decision making in pest management. Pest detection with ...
Chloris gayana Kunth under different defoliation regimes. Morphogenesis, sward structure and leaf area index
(2019-10-09)
Subtropical pastures are an important alternative to increase forage yields to fulfil cattle nutritional requirements. Despite the increasing expansion of these pastures in the semiarid subtropical region of Argentina, ...
Communities of arbuscular mycorrhizal fungi associated with perennial grasses of different forage quality exposed to defoliation
(Academic Press Ltd - Elsevier Science Ltd, 2018-07)
Vegetation management practices, such as defoliation may alter the composition of plant communities and/orthe fungi-forming arbuscular mycorrhiza (AMF). We determined the species identity, density, frequency anddiversity ...
Size/density compensation in Chloris gayana Kunth cv. Fine Cut subjected to different defoliation regimes
(Wiley, 2012-06)
The study evaluated the plasticity of Chloris gayana Kunth cv. Fine Cut to defoliation in terms of tiller size/density compensation (SDC). Twelve mini‐swards were grown in a greenhouse under non‐limiting water and nutrient ...
Reproductive development of Lotus tenuis (fabaceae) crop defoliated at different times and intensities
(Scientific Research Publishing, 2016)
Lotus tenuis forage yield has been quantified under defoliation conditions in pastures, grasslands and under dual-purpose production of both livestock forage and seeds. However, little is known about the effects of defoliation ...
Effect of defoliation frequency on Rytidosperma virescens plants and arbuscular mycorrhizal fungi colonization
(Elsevier, 2022-06-09)
Rangelands provide different ecosystem services to satisfy human needs. Although grazing management in southern Patagonia is mostly characterized by extensive continuous grazing, rotational grazing management may improve ...
Quantifying massive outbreaks of the defoliator moth Ormiscodes amphimone in deciduous Nothofagus-dominated southern forests using remote sensing time series analysis
(Blackwell Publishing Ltd, 2019)
Forest insect outbreaks are one of the major biotic disturbances on natural and artificial landscapes. Although abundant literature of insect outbreaks exists in the Northern Hemisphere, studies for the Southern Hemisphere ...
Defoliation patterns and their implications for the management of vegetative tropical pastures to control intake and diet quality by cattle
(Wiley, 2016-09)
This study assessed the use of pasture attributes to control daily intake and diet quality during progressive defoliation on pastures of Axonopus catarinensis. Three consecutive 12‐day grazing treatments of progressive ...
