“…While research advances in developing improved genotypes, grazing management practices have also been improved to take advantage of the high yield and nutritive value of the BRS Kurumi, reducing the need for mechanical control (mowing) of the canopy structure (Gomide et al, 2011;Sousa et al, 2012;Chaves et al, 2013;Pereira et al, 2016) (Figure 5).…”

Elephantgrass (Pennisetum purpureum Schum. syn. Cenchrus purpureus) is one of the most important forage plants worldwide, cultivated in almost all tropical and subtropical regions due to its high potential for dry matter production, nutritional value, acceptability by different animal species and categories, vigor, and persistence. It has shown great potential for biomass energy production and other forms of non-forage use. This study aimed to review the current knowledge about the cultivation and use elephantgrass focused on pasture and silage. The study also describes the main morphological, genetic, and cytogenetic characteristics of the species, and methods and strategies for obtaining improved cultivars. The release of dwarf type cultivars for grazing and cultivars with high-yield potential for silage has increased the interest in the cultivation of elephantgrass in the beef and dairy cattle production.

“…This form of defoliation avoids the excess of senescence at the plant's base and the excessive internodes' elongation (Iqbal et al, 2017). The excessive internodes elongation affects the pastureland structure, most especially to determine the distancing among the leaves, which hampers the animals' grazing (Souza et al, 2012). After defoliation, the residual structure is also hampered by the defoliation delay, as fewer living leaves remain to ease the regrowth (Hinman & Fridley, 2020).…”

Structural dynamic of the annual ryegrass from defoliation to seeds harvest

The aerial part distribution and arrangement can significantly affect the forage resource's use, both for the leaves and seeds harvesting. This work aimed to verify the structure derived from different times of pasture use and the subsequent seeds production in a long-cycle ryegrass cultivar. Weekly assessments of number and length of living leaves, elongation of the internodes, tillering, plants' height, structural components (leaf, stem, flower, and dead material), seeds yields components, and seeds yield, to determine the pasture structure along its production cycle. The ryegrass cv BRS Ponteio pasture had its structure significantly modified just after 150 days (thermal sum: 1303 degrees-days) from seeding without the defoliation. Defoliation during the vegetative period did not alter the plants' structure until the seeds' production.Defoliation just after the beginning of the internodes' elongation caused a significant tillering growth, which maintained the high seeds production potential, without plants lodging, besides promoting a more significant leaves harvesting.Subsequent pasture use determined predominant stems and flower harvesting, compared to the leaves, and the significant reduction of the production seeds and potential seeds production.
