“…C 4 plants are known to accumulate nitrogen in higher quantities when compared to C 3 plants, such as annual garden rocket (Ehleringer & Monson, 1993). This relationship between higher nitrogen uptake efficiency in C 4 plants has also been reported in many grass species (Beale & Long, 1997;Rubio et al, 2010); and occurs due to the higher energy requirements of C 4 carbon fixation, particularly with regards to rubisco activity during photosynthesis which becomes saturated with CO 2 (Carmo-Silva et al, 2010;Ghannoum et al, 2005).…”

Perennial wall rocket (Diplotaxis tenuifolia [L.] DC.) and annual garden rocket (Eruca sativa Mill.) are cultivated around the world as salad crops and as an ingredient of condiments. From a botanical perspective these species are classified in the Rapa/Oleracea linage, which is consistent with their similar morphological characteristics, chromosomal number and the diversity of glucosinolates. It is understandable that these species have been informally grouped together for convenience. However, the evaluation of a wide range of factors over a typical production cycle has clearly illustrated that these species should be considered distinct crops from a commercial perspective. We will demonstrate with examples why these species should be managed differently and considered commercially distinct crops.

“…Reported results represent annual production of biomass consisted of stems, leaves and inflorescences. During winter nutrients were transferred from the aboveground parts back to rhizomes and used in next vegetative period (Beale and Long 1997), most of the leaves were rip off by the wind and stems were dried, yield decreased about 30% but biomass quality increased (Lewandowski and Heinz 2003).…”

Miscanthus × giganteus (Greef et Deu) is an agro-energy crop of the second generation cultivated in purpose to obtain annually renewable bio-fuel produced from the aboveground biomass. Cultivation is preferred on marginal lands to avoid occupation of arable lands. Influence of fertilization and soil type Gleysol, Planosol and Technosol (open pit coal mine overburden) on yield and biomass traits of miscanthus were investigated during five years’ field experiment. Among biometric characteristics: stem height, length and width of leaves, the number of leaves (dry and green) per stem and number of stems per rhizome, only the last one has a strong positive correlation with yield. Fertilization increased yield during fourth and fifth year of development on Gleysol and Technosol. The highest yield on Gleysol was 23.12 t/ha in 2014, on Planosol 10.16 t/ha, and 4.77 t/ha in 2015 on Technosol. The yield of miscanthus, beside fertilization, depends on weather conditions and weeds. Cultivation of miscanthus is possible on marginal soils with minimum application of agricultural measures only in the year of establishment. Gleysol is a type of soil that can be recommended for miscanthus cultivation.

“…The crop is established via the propogation of rhizome cuttings and is harvested annually. In contrast to first-generation biofuel feedstocks, its demand for added fertilisers is low due to an efficient nutrient handling capacity -at the end of the growing season, nutrients are translocated from the stems and leaves to the rhizomes for storage and utilisation the following season [127]. This is likely to ensure that the nitrous oxide emissions from Miscanthus-producing soils will be significantly less than for first generation feedstocks [128,129] [12].…”

“…It is important, however, that such a practice considers the dynamics of nutrient transfer in the plant and any associated effects on stand fertility in subsequent years [127,137]. This study assumes that early winter biomass yields will be 40% higher than those seen in the spring.…”

The role that lignocellulosic feedstocks and various biorefining technologies can play in meeting Ireland's biofuel targets

Modern biorefineries target the production of chemicals and fuels from lignocellulosic biomass feedstocks such as energy crops and biodegradeable wastes. Biofuels produced from such processes are considered "second-generation-biofuels" and are considered to be more sustainable than first-generation-biofuels from food and oil crops. This paper considers the contribution that biorefineries can make in the Republic of Ireland to the mandated 10% biofuel quotient for 2020. This is done by considering eight different technologies and the practical quantities of waste suitable for them. It is concluded that between 3.5 and 5.7% of the 2008 demand for biofuels can be met from the utilisation of wastes and residues in near-term biorefining technologies and that up to 5% of the 2020 petrol and diesel demand can be met via processing a similar quantity of waste in an advanced enzymatic hydrolysis technology. The remaining biofuel requirements can be met by processing energy crops in either this or an advanced thermochemical facility. Between 1.8 and 13.7% of the agricultural area of Ireland is required for the production of these crops, depending on the particular feedstock. The production of a high-yielding Miscanthus crop that is harvested directly after senescence will place the minimum requirement on Irish land.
