“…v.70, n.1, p.6-11, January/February 2013 Forages with greater potential for ensiling must have an adequate chemical composition for fermentation and increased productivity. Cunha et al (2011) also evaluated the dry matter yield of the same clones used in the current study and reported the following values: 6,258 kg ha -1 for Taiwan A-146 2.37, 4,952 kg ha -1 for Taiwan A-146 2.114, 5,756 kg ha -1 for Elephant B, 6,873 kg ha -1 for HV 241 and 4,465 kg ha -1 for Mott. Silva et al (2011a) evaluated five dwarf elephant grass clones.…”

Ensiling warm-season grasses often requires wilting due to their high moisture content, and the presence of low-soluble sugars in these grasses usually demands the use of additives during the ensiling process. This study evaluated the bromatological composition of the fodder and silage from five Pennisetum sp. clones (IPA HV 241, IPA/UFRPE Taiwan A-146 2.114, IPA/UFRPE Taiwan A-146 2.37, Elephant B, and Mott). The contents of 20 Polyvinyl chloride (PVC) silos, which were opened after 90 days of storage, were used for the bromatological analysis and the evaluation of the pH, nitrogen, ammonia, buffer capacity, soluble carbohydrates, and fermentation coefficients. The effluent losses, gases and dry matter recovery were also calculated. Although differences were observed among the clones (p < 0.05) for the concentrations of dry matter, insoluble nitrogen in acid detergents, insoluble nitrogen in neutral detergents, soluble carbohydrates, fermentation coefficients, and in vitro digestibility in the forage before ensiling, no differences were observed for most of these variables after ensiling. All of the clones were efficient in the fermentation process. The IPA/UFRPE TAIWAN A-146 2.37 clone, however, presented a higher dry matter concentration and the best fermentation coefficient, resulting in a better silage quality, compared to the other clones.

“…At planting, 110 kg P ha −1 and 100 kg K ha −1 were evenly distributed along the furrows. After fertilization, plots were subjected to five experimental cuts at 56 d of regrowth at 10 cm from the soil surface preceding the beginning of the experiment (Cunha et al, 2011).…”

“…Among the cultivars of elephantgrass generated in breeding programs, the dwarf types have morphological and yield differences (Cunha et al, 2011) compared with taller cultivars and have great potential for ruminant livestock production (Almeida et al, 2000b; Flores et al, 1993; Silva et al, 1994). Forage nutritive value coupled with the biomass yield makes elephantgrass an important alternative for livestock production systems, including small ruminants.…”

Adaptability and Stability Analysis for Selection of Elephantgrass Clones under Grazing

et al. 2015

Adaptability is the capacity of a genotype to respond favorably to changes in the environment, while stability is the capacity to have highly predictable performance in different environmental conditions. In this study, the stability and adaptability of eight Pennisetum spp. clones were assessed. Genotypes analyzed in this research included five dwarf elephantgrass (Pennisetum purpureum Schumach.) cultivars (Taiwan 2.27, Taiwan 2.37, Taiwan 2.114, Merker México 6.31, and Mott), two tall elephantgrass cultivars (IRI 381 and Elephant B), and one interspecific hybrid (HV 241) of elephantgrass and pearl millet [P. purpureum × P. glaucum (L.) R. Brown]. Adaptability and stability parameters were estimated for the following variables: herbage mass (HM), herbage accumulation rate (HAR), number of green leaves per tiller (NL/T), number of tillers (NT), and leaf/stem ratio. Interaction between clones and grazing periods occurred (P ≤ 0.05) for all variables. Herbage mass ranged from 2180 kg dry matter (DM) ha−1 (Taiwan 2.37) to 3383 kg DM ha−1 (Mott), averaging 2796 kg DM ha−1. Except for HV 241, which displayed specific adaptability to a favorable environment in HM and NT, the clones displayed wide adaptability. Dwarf genotypes (Taiwan 2.27, Taiwan 2.114, and Mott) displayed greater (P ≤ 0.05) capacity of leaf production per tiller than the other entries. Mott and Taiwan 2.114 were selected for the next phase of the breeding program on the basis of stability, HAR, and NL/T.

“…The variable "number of tillers" gathered the largest number of families that met such condition, namely: Cameroon x Cuba-11; Cameroon x Guaçu/I.Z.2; Capim Cana D'África x Guaçu I.Z.2; CPAC x Cuba-115; Capim Cana D'África x Cuba-115; IAC-Campinas x IJ 7139; and IAC-Campinas x Guaçu/I.Z.2; when both assessment cuts were taken into consideration (Table 4). The number of tillers is relevant in studies that aim to increase the dry biomass production because there is a correlation between high genetic nature and dry matter production (Cunha et al, 2011). Only a single family, derived from the crossing between Cameroon x Guaçu/I.Z.2, showed plant height above the mean when both assessment cuts were taken into consideration.…”

“…According to Cunha et al (2011), such situation is favorable, because it is known that the elephant grass, like all forage plants, is subject to seasonality. Thus, it presents productivity variation in certain periods of the year.…”

ABSTRACT. Brazil has great potential to produce bioenergy since it is located in a tropical region that receives high incidence of solar energy and presents favorable climatic conditions for such purpose. However, the use of bioenergy in the country is below its productivity potential. The aim of the current study was to select full-sib progenies and families of elephant grass (Pennisetum purpureum S.) to optimize phenotypes relevant to bioenergy production through mixed models
