Agronomic Evaluation of Ethiopian Mustard (brassica Carinata A. Braun) Germplasm and Physical-energy Characterization of Crop Residues in a Semi-arid…
2017
Brassica carinata A. Braun is one of the most interesting oilseed crops suited to arid and semi-arid areas for energy purposes. Several studies have highlighted the possibility of introducing this species into cropping systems, typical of Mediterranean region. The aims of this study were to evaluate the agronomic performance of Brassica carinata germplasm under Mediterranean climatic conditions and to assess the physical and energy characteristics of crop residues and pellets made from the residues. A total of 20 different accessions of Brassica carinata were compared in a semi-arid area of Sicily (Italy). In the two-year test period, the main morphological and yield parameters of the acces…
Long‐Term Tillage and Cropping System Effects on Chemical and Biochemical Characteristics of Soil Organic Matter in a Mediterranean Semiarid Environm…
2015
Several studies have reported how tillage and cropping systems affect quantity, quality, and distribution of soil organic matter (SOM) along the profile. However, the effect of soil management on the chemical structure of SOM and on its hydrophobic and hydrophilic components has been little investigated. In this work, the long-term (19 years) effects of two cropping systems (wheat monoculture and wheat/faba bean rotation) and three tillage managements (conventional, reduced, and no tillage) on some chemical characteristics of SOM and their relationships with labile carbon (C) pools were evaluated. Soil samples were taken from the topsoil (0–15 cm) of a Chromic Haploxerert (central Sicily, I…
Tirdzniecības atvērtības ietekme uz ekonomikas izaugsmi, CAE valstu empīriskais pētījums
2021
Darba mērķis ir izpētīt tirdzniecības atvērtības ietekmi uz ekonomikas izaugsmi, izmantojot 16 Centrālās un Austrumeiropas valstu paneļa datus 2010. – 2019. gadā, salīdzinot 4 dažādus tirdzniecības atvērtības rādītājus. Apvienotie OLS un fiksētie efekti tiek izmantoti kā primārie novērtētāji, un noturības analīzei tiek izmantots sistēmas GMM tests. Apkopoto OLS un fiksēto šķērsgriezumu regresiju iegūtie rezultāti parāda, ka dažādos tirdzniecības atvērtības mērījumos tirdzniecības atvērtība pozitīvi un ļoti nozīmīgi ietekmē ekonomikas izaugsmi. GMM sistēmas testi parāda tirdzniecības atvērtības negatīvo ietekmi uz ekonomikas izaugsmi, bet nozīmīgumu ieguva tikai divi atvērtības rādītāji.

La coltivazione della calendula (Calendula officinalis L.) come prodotto erboristico.
2009
All’interno della flora officinale mediterranea, la famiglia delle Asteracee (ex Composite) assume un ruolo di primaria importanza, comprendendo circa il 19% del totale delle specie di interesse erboristico censite in Sicilia. Tra queste, molto rappresentata è la calendula (Calendula officinalis L.), la cui droga è tradizionalmente costituita dai capolini, di un acceso colore arancione, che vengono largamente adoperati, da soli o in miscela con altri derivati vegetali, in erboristeria e dall’industria farmaco-cosmetica. Le proprietà attribuite alla specie sono numerose e assai diversificate: oltre alle note e tradizionalmente utilizzate azioni antiinfiammatoria, cicatrizzante, emolliente ed…
Relationship between recruitment and mother plant vitality in the alien species Acacia cyclops A. Cunn. ex G. Don
2014
Acacia cyclops is a widespread invader in Mediterranean-climate regions. However, although its naturalization in the Mediterranean Basin dates back only a few years ago, and the invasion process has not been studied hitherto. We investigated seedlings recruitment strategy adopted by A. cyclops in a small island (Lampedusa, Italy) where its natural regeneration was strictly confined under mother plants canopy. Healthy plants (DCP), plants at incipient senescence (SCP) and dead plants (DP) were distinguished according to vitality and canopy status. Living plants were also characterized in relation to leaf C and N isotope composition. Regeneration pattern (seedlings and saplings abundance) was…
Il cappero: analisi desk sui flussi di commercializzazione in Italia e nei principali Paesi competitors
2009
In questi ultimi anni, il commercio di cappero, a livello internazionale, ha fatto registrare un trend positivo rappresentato da uno scambio di prodotto pari, secondo dati forniti dal COMTRADE, a circa 3 mila tonnellate. A fronte di tali incrementi, in Italia, la superficie investita a cappero è scesa drasticamente, passando da circa 1000 ha nel ’83 a circa 170 ha nel 2006. Ciò, presumibilmente, è dovuto alla carente attuazione di sapienti strategie di marketing sul prodotto cappero da parte degli imprenditori agricoli. In quest’ottica, nell’ambito del progetto “IL CAPPERO DELLE ISOLE MINORI”, è stata avviata una ricerca con lo scopo di elaborare un piano strategico di rilancio del comparto…
