Switchgrass (Panicum virgatum L.) has potential for both bioenergy and forage. The objectives of this experiment were to: i) determine whether switchgrass could be harvested for greater nutritive value during the vegetative stage relative to early reproductive growth (boot stage); ii) compare biomass yields of switchgrass harvested once versus twice per year for bioenergy; and iii) examine effects of N fertilizer rates on harvest systems. The experiment was a randomized complete block design…

Nitrogen Fertilization and Harvest Timing Affect Switchgrass Quality

Early season switchgrass (Panicum virgatum L.) can be used as animal feed and mature late-season biomass as a biofuel feedstock. However, nitrogen (N) application and harvest timing effects on the

Seeding rate and nitrogen application effects on oat forage yield and nutritive value

Abstract Nitrogen (N) is the most limiting nutrient for forage production. This study determined seeding rate effects and optimum N rate for spring oat (Avena sativa L.) forage production in the

Switchgrass as a bioenergy feedstock: advances in breeding and genomics research

Switchgrass (Panicum virgatum L), a native perennial of the North American prairie, possesses high biomass yield potential in marginal environments with limited input and conventional population improvement approaches such as recurrent restricted phenotypic selection (RRPS) are effective in improving forage yield and digestibility.

Switchgrass Establishment Can Ameliorate Soil Properties of the Abandoned Cropland in Northern China

The bioenergy crop switchgrass (Panicum virgatum L.) has been recognized as friendly to the soil of cultivated land depending on the previous land use types and management practices. However, the

Harvesting a winter rye energy cover crop (Secale cereale L.) could help sustain growing food and energy demand, provide new revenue streams, and enhance ecosystem services without inducing land-use

Influence of Height‐Based Management on Forage Nutritive Value of Four Warm‐Season Forage Grasses

This study aimed to observe nutritive value changes in talland short-growing warmseason grasses with repeated cuttings to determine appropriate cutting frequency and estimate forage nutritivevalue in the field from herbage mass (HM).

Effect of Biogas Digestate and Mineral Fertilisation on the Soil Properties and Yield and Nutritional Value of Switchgrass Forage

The aim of this study was to assess the effect of a three-year application of digestate from an agricultural biogas plant on the physicochemical properties of highly acidic pHKCl 4.4 ± 0.23, silty

Rapid declines occurred in leaf crude protein and IVDMD throughout the growing season, indicating that leaf maturation primarily is responsible for declining forage quality rather than increasing plant development, i.e., increasing stem growth, in these grasses.
