“…Since high planting densities reduce stem diameter more than stem height (Denoroy, 1996), the strong mutual shading which occurs particularly when water and N were not limiting factors promotes the early senescence of the lower parts of the canopy. Moreover, such dense crops are often prone to disease and lodging, and this decreases final yield (Meijer and Mathijssen, 1996). Thus, the use of low planting densities seems to be much more appropriate particularly when the cultivars show vigorous stem growth and strong aerial branching.…”

Jerusalem artichoke is commonly grown for its edible tubers, livestock feed and as an ornamental. The possibility of growing Jerusalem artichoke for energetic purposes has aroused scientific interest in this species. Despite several studies that have already been done in the last few decades, many aspects of the cropping practice are still relatively unknown. During the growing seasons of 2004-2006 field trials were carried out in NE Portugal. In the experimental period different cropping conditions were imposed, regarding planting density, N fertilization and propagation method. (2006) conditions. Nitrogen significantly increased tuber yield in 2005 only when seed-tubers were used. Averaged across N fertilization rates and planting densities mean tuber dry matter yields were 12.8 and 6.9 Mg ha -1 for seed-tuber and botanical-seed, respectively. Leaf mineral composition was little affected by cropping practices. The 'Bragança' clone showed high tuber yield potential, although the mean weight of the individual tubers was low which could make mechanization of the harvest difficult. The poor results achieved with botanicalseed argue against its use as an alternative to the seed-tubers.Additional key words: botanical-seed, leaf mineral composition, nitrogen fertilisation, planting density, seed-tuber. Resumen Producción de tubérculos y composición mineral en hojas de pataca (Helianthus tuberosus L.) utilizando diferentes prácticas de cultivoLa pataca se cultiva por sus tubérculos comestibles, también se utiliza como forraje y como planta ornamental. La perspectiva de que se pueda cultivar con fines energéticos ha incrementado el interés por esta especie. -1 ) combinados de forma factorial con las densidades de plantación. La máxima producción de materia seca en tubérculos fue de 18,4 Mg ha -1 (65,6 Mg ha -1 , en peso fresco) y se obtuvo en las parcelas en las que se combinaron 100 kg N ha -1 , 2 plantas m -2 y propágulos vegetativos. La mejor densidad de plantación fue de 2 plantas m -2 , tanto en regadío como en secano. La aplicación de nitrógeno aumentó significativamente la producción, pero sólo cuando se utilizaron propágulos vegetativos. Con propágulos vegetativos y semilla botánica se obtuvieron producciones medias de materia seca de 12,8 y 6,9 Mg ha -1 , respectivamente. La composición mineral de las hojas se vio poco afectada por la técnica de cultivo. El clon 'Bragança' ha mostrado elevado potencial de producción, aunque el peso medio de los tubérculos individuales haya sido bajo, lo que puede dificultar la mecanización de la cosecha. Los bajos resultados obtenidos a partir de semilla botánica disuaden su uso en alternativa a los propágulos vegetativos.Palabras clave adicionales: composición mineral de las hojas, densidad de plantación, fertilización nitrogenada, semilla botánica, tubérculo-semilla.

-Social, economic and environmental importance of bio-based economy is rapidly growing and vegetable oils play an important role. About 75% of global production of vegetable oils derives from commodity oilseeds (i.e., soybean, oil palm, rapeseed), while the remaining 25% is produced from minor oilseeds characterized by unusual fatty acid composition. The present review aims at analyzing the potentialities of two alternative oilseed crops for Europe, camelina (Camelina sativa) and crambe (Crambe abyssinica), identified as major candidates for the future European bio-based economy as testified by the recently funded EU Project (Horizon 2020) COSMOS (Camelina and crambe Oil crops as Sources of Medium-chain Oils for Specialty oleochemicals). The interest on camelina and crambe is mainly due to their unique fatty acid profile, low input management and wide environmental adaptability. We attempted to analyze pros and cons of development of camelina and crambe in Europe in the light of biorefinery concept (i.e., using oil and whole produced biomass) as undertaken by COSMOS project.Keywords: Bioeconomy / oil crops / Brassicaceae / PUFA / eicosenoic acid / erucic acid Résumé -La bioéconomie, tremplin de développement pour la cameline et le crambe. L'importance sociale, économique et environnementale de l'économie reposant sur le bio, est en pleine expansion et les huiles végétales y jouent un rôle important. De l'ordre de 75 % de la production mondiale d'huiles végétales provient de graines oléa-gineuses (à savoir le soja, le palmier à huile et le colza), tandis que les 25 % restants sont produits à partir de graines oléagineuses mineures caractérisées par une composition inhabituelle en acides gras. Le présent article vise à analyser le potentiel pour l'Europe de deux cultures oléagineuses alternatives, la caméline (Camelina sativa) et le crambe (Crambe abyssinica), identifiées comme les principaux candidats à la future bio-économie européenne comme en témoigne le projet de recherche dit COSMOS (acronyme de : Camelina and crambe Oil crops as Sources of Medium-chain Oils for Specialty oleochemicals, ou Les cultures de cameline et de crambe comme sources d'huiles à chaîne moyenne pour les produits oléochimiques de spécialité) financé dans le cadre du programme Horizon 2020 de la Communauté européenne. L'intérêt porté à la caméline et au crambe est principalement lié à leur profil unique d'acides gras, à leur faible demande d'intrants et à leur large capacité d'adaptation environnementale. Nous avons tenté d'analyser les avantages et les inconvénients du développement de la caméline et du crambe en Europe à la lumière du concept de bioraffinerie (à savoir, en utilisant l'huile et toute la biomasse produite) comme dans le cadre du projet COSMOS.

“…The interception and absorption of solar radiation define the crop capacity to accumulate biomass [21,29]. The crop radiation use efficiency (RUE) is comparable to that reported for others C3 species and has values of 2.7-2.9 g•MJ −1 [2,29]. Monti et al [18] observed that RUE calculated considering the total dry matter is affected by water availability more than RUE calculated for fructan yield.…”

“…Leaf area index (LAI) reflects the photosynthetically active area of leaves. Meijer and Mathijssen (1996) [29] reported that under no limiting conditions, leaf expansion and canopy longevity are strongly dependent on temperature. Furthermore, leaf extension and thus LAI are more affected by water regime than leaf biomass is [18].…”

Jerusalem Artichoke (Helianthus tuberosus L.): A Versatile and Sustainable Crop for Renewable Energy Production in Europe

Recently, biofuels have become a strategic focus to reduce vehicle emissions and increase sustainability of the transport sector. However, the sustainability of biofuels production has been questioned owing to its implications for future land footprint. In this respect, the EU Commission has very recently classified as low indirect land-use change (ILUC)–risk biofuels those obtained by crops grown on marginal lands and with low external inputs. Only few crops can reach high yields under both of these conditions across Europe. From this point of view, Jerusalem artichoke (Helianthus tuberosus L.) is certainly a species worthy of remark since it has all the attributes to accomplish the aims of the updated EU Renewable Energy Directive (RED II). Starting from physiological aspects, the present review examines and summarizes literature on the ecology, genetic resources, agronomic practices and sustainability of this species. The goal is to point out the recent advances of research in Jerusalem artichoke (JA) potential as alternative biofuel feedstock and to identify what is still needed to better characterize its environmental benefits and agronomic performance.
