“…The mean values of the dry matter yield (DMY), the percentage of crude protein (%CP), and the percentage of neutral detergent fiber (%NDF) per genotype and the Skott-Knott cluster at 5% probability are shown in Table 3. In a similar research, when assessing production and biomass quality characteristics of six elephant-grass genotypes under five different production ages, Vidal et al [13] obtained dry matter yield ranging from 5.26 to 7.27 t ha -1 in eight-week age.…”

In the elephant-grass germplasm, there are genotypes that show a large genetic variability differentiated by morphological, reproductive, agronomic and biochemical characteristics. As such, there is a selection of new and more adapted elephant-grass genotypes, with greater productivity and nutritional quality, which can cause an increase in the forage offer, especially during the dry season. Thus, this work aimed at evaluating, throughout two years, the productive performance and nutritional value of 53 elephant-grass genotypes to produce forage in the edaphoclimatic conditions in Campos dos Goytacazes city, Rio de Janeiro State, Brazil. The experiment was composed of 53 elephant-grass accessions from the Banco de Germoplasma da Embrapa Gado de Leite (Germplasm Bank of Embrapa Gado de Leite), located in Coronel Pacheco city, Minas Gerais state, Brazil. It was applied the randomized complete block experimental design with 53 accessions two replications. Cuttings were performed every two months, throughout two years, totaling ten cuttings. The morpho-agronomic and bromatological characteristics were assessed, and the statistical analyses were carried out applying the Computational Applicative in Genetic and Statistics, Genes. Results indicated that there is a wide genetic variability among the elephant-grass genotypes concerning the characteristics under study. The Mineiro, Guaçu IZ-2 and Acesso 91 – EMBRAPA genotypes were those that showed to be superior to all traits evaluated simultaneously. They proved to be the most productive and with higher nutritional quality. Therefore, they are the most indicated to produce forage in the edaphoclimatic conditions of Campos dos Goytacazes city, Rio de Janeiro State.

“…Mott), which is a fast-growing plant that is durable against environmental conditions. Although it is classified as a forage plant, it is also an energy crop with a high calorific value, allowing it to be burned directly or to be used to produce biogas for electricity production, resulting in a lower environmental impact than direct fuel combustion ( Ana et al., 2017 ; Deshmukh et al., 2015 ). When comparing biogas production from P. purpureum to that from other raw materials, such as palm oil and cassava, P. purpureum was reported to have lower production costs and provide products throughout the entire year ( Sawasdee and Pisutpaisal, 2014 ; Ibrahim, 2019 ).…”

The purpose of this research was to investigate the effects of cow manure and acacia wood-derived biochar on the immobilization of arsenic (As) and manganese (Mn) in contaminated mine tailings using Mott dwarf Napier grass ( Pennisetum purpureum cv. Mott). Cow manure or acacia wood-derived biochar was separately mixed with mine tailings at rates of 1, 3, and 5% (w/w). Samples of mine tailings and plants were collected every 30 d during the 120-d period. The total As and Mn accumulation amounts in the plants were analyzed in both the underground (roots) and aboveground (stems and leaves) parts of the plants. The results revealed that cow manure and acacia wood-derived biochar can reduce the mobilization of As and Mn in mine tailings and thus reduce their uptake and accumulation in P. purpureum . Acacia wood-derived biochar was able to stabilize and immobilize As and Mn in mine tailings, allowing the metals to be taken up for plant utilization despite the lower plant growth (biomass and relative growth rates) than that obtained with added cow manure. The accumulation amounts of As in the aboveground and underground parts of P. purpureum grown in mine tailings with 5% BC application were 0.52 ± 0.05 mg kg −1 and 1.57 ± 0.1 mg kg −1 , respectively, while the accumulation amounts of As in the aboveground and underground parts were 31 ± 1.08 mg kg −1 and 73.05 ± 2.60 mg kg −1 , respectively. In other words, the percentage reductions in As and Mn uptake and accumulation in the aboveground and underground parts were 78.6% and 63.9% for As and 72.5% and 69.3% for Mn, respectively. The results of this study can be applied for the remediation of heavy metal-contaminated areas, especially gold mines and surrounding areas, as well as in other areas.

“…The aim was to reduce the toxicity value using Pennisetum purpureum cv. Mott, a biomass plant that has received attention for the production of renewable energy (Ana et al, 2017), and has a low cost of planting, a fast growth rate, high yield per 1,600 m 2 , and is easy to maintain (Sarwanto and Tuswati, 2018).…”

This research firstly aimed to study the potential of electrokinetics (EK) on arsenic (As) mobility in gelatin (agar) medium with different containers (spherical or rectangular), electrodes (graphite or stainless-steel grade 316L), and applied electric field (0, 1, and 2 V cm− 1) by dividing the area into nine parts to ascertain the As movement (horizontally and vertically) after 72 h. Secondly, utilizing the optimal conditions for As mobility from the first part, to ascertain the effect of EK with Mott Dwarf Napier Grass (Pennisetum purpureum cv. Mott) for the co-treatment of mine tailings at an applied electric field of 0, 1, 2, and 4 V cm− 1 to examine the As accumulation in the plants and mine tailings after 15, 30, 45, 60, 75, 90, 105, and 120 d. The results showed that As had the highest mobility in agar in the spherical container using graphite electrodes with an applied electric field of 2 V cm− 1. The areas around the cathodes had lower As levels than that around the anode, with a net movement from cathode to anode areas both horizontally and vertically. For the co-treatment of mine tailings with EK and P. purpureum cv. Mott cultivation, the applied electric field provided better As treatment results than without an electric field, and the plants accumulated As in their roots to a greater extent than in the stem and leaves. The highest As absorption capability in the roots of P. purpureum cv. Mott (7.69 ± 0.16 mg kg− 1) was obtained after 90 d with an applied electric field of 1 V cm− 1.
