Abstract:
... Silage is one of the typical systems to preserve biomass usually oriented from corn, sorghum, wheat, grass, and other forage and perennial crops. A critical task within the logistics operations in silage production, i.e. harvesting, transporting, and compacting, is the management of the biomass flow, in connection with the biomass storage system and the required conditions of the stored product de ...

Abstract:
... Wheat streak mosaic virus (WSMV) causes wheat streak mosaic disease, a potentially devastating infection of wheat with a worldwide distribution. WSMV is a positive-sense, single-stranded, monopartite RNA virus in the family Potyviridae. WSMV is vectored by the wheat curl mite (Aceria tosichella Keifer), and seed-transmission has been reported at a very low rate (Jones et al. 2005). This virus infe ...

Abstract:
... The Midwestern U.S. landscape is one of the most highly altered and intensively managed ecosystems in the country. The predominant crops grown are maize (Zea mays L.) and soybean [Glycine max (L.) Merr]. They are typically grown as monocrops in a simple yearly rotation or with multiple years of maize (2 to 3) followed by a single year of soybean. This system is highly productive because the crops ...

Abstract:
... The deployment of dedicated energy crops and the related land-use change are topical issues, particularly in relation to carbon storage and climate change mitigation effects. In order to maximize their mitigation potential and to fully supply new biorefineries, perennial energy crops may be established, not only on former idle and grazing lands, but also on the least remunerative cropland, as indi ...

Abstract:
... Tropical forage grasses of the genus Megathyrsus and Urochloa can suppress soil–nitrification by releasing inhibitory substances, reducing N losses and increasing fertilizer N recovery of the cash crop in rotation. In contrast, ruzigrass (Urochloa ruziziensis) has been reported to decrease the yield and N accumulation of the subsequent crop and hence can affect N use efficiency and the fate of app ...

Abstract:
... BACKGROUND: Switchgrass (Panicum virgatum L.), a warm-season perennial C4 plant, can be used as a forage plant, a soil and water conservation plant, a windbreak plant, and as a good source of biofuels and alternative energy with low planting costs. However, switchgrass exhibits low rates of seedling development compared to other crops, which means it is typically out-competed by weeds. There is a ...

Through genome-wide bioinformatic analysis of switchgrass Zinc finger-CCCH genes (PvC3Hs), we found that several PvC3Hs, including PvC3H72, might play regulatory roles in plant cold tolerance. The objectives of this study were to c ...

Abstract:
... A growing bioeconomy demands high, but sustainable production of biomass.

Harvesting of silage maize in late autumn on waterlogged soils may result in several ecological problems such as soil compaction and may subsequently be a major threat to soil fertility in Europe. It was hypothesized that perennial energy crops might reduce the vulnerability for soil compaction through earlier harvest dates and improved soil stability. However, the performance of such crops to be ...
