Faba bean grain yield, N2 fixation, and weed infestation in a long-term tillage experiment under rainfed Mediterranean conditions
2012
Background and Aims Long-term experiments could provide valuable information to determine the effects of an agronomic practice on agro-ecosystem productivity and stability. This study evaluated the long-term (18-year) impact of different tillage systems on faba bean (Vicia faba L.) productivity, including weed and broomrape incidence, and N2 fixation. Methods The experiment was carried out on a Vertisol under rainfed Mediterranean conditions. It was set up as a strip plot design. The tillage systems were: conventional tillage (CT) with moldboard plow, reduced tillage (RT) with chisel plow, and no tillage (NT). Nitrogen fixation was estimated over 2 years in the final phase of the experiment…
Le varietà di grano duro per le semine 2016: Sicilia
2016
Le prove di confronto varietale di frumento duro realizzate in Sicilia, con il coordinamento del CREA, sono state allestite in 4 diversi ambienti: Libertinia (Catania), Catania, Cammarata e S. Stefano Quisquina (Agrigento). Fra i genotipi in prova nel quadriennio considerato, in 15 differenti condizioni ambientali (località × annata), la cultivar Monastir ha mostrato le migliori performance, con rese superiori alla media di campo in 13 prove su 15. Buona stabilità produttiva è stata verificata anche per le varietà Ramirez, Anco Marzio, Kanakis, Iride, Core e Alemanno. Fra le varietà in prova nel triennio 2014-2016, Anta- lis conferma la sua ottima adattabilità ed elevata stabilità produttiv…
Le varietà di grano duro per le semine 2017: Sicilia
2017
Nell’annata agraria 2016-2017, le prove sperimentali per la valutazione di 28 varietà di frumento duro sono state allestite in Sicilia, con il coordinamento del CREA, in 5 diversi ambienti: Libertinia (Catania), Piazza Armerina (Enna), Catania, Cammarata (AG) e S. Stefano Quisquina (AG). ). I dati evidenziano che, fra i genotipi in prova nell’ultimo quadriennio in 17 differenti condizioni ambientali (località × annata), le cultivar Antalis, Monastir, Kanakis, Ramirez, Iride, Core e Alemanno hanno ampiamente dimostrato la loro elevata produttività e ottima stabilità produttiva negli ambienti siciliani.
Organic and chemical N fertilization on coriander (Coriandrum sativum L.)
2014
Coriander (Coriandrum sativum L.) is an annual herbaceous Medicinal and Aromatic Plant (MAP) dealing with a great industrial interest because of its strongly-scented fruits (“seeds”). The role of N fertilization in coriander seed yield is matter of debate as far; information is missing, for instance, about the effects of organic N fertilization, a mandatory technique when the organic cropping management is chosen. Organic and chemical N fertilizers have been supplied on coriander from 2001–2002 to 2006–2007 in a Mediterranean semi-arid environment, and their effects on the formation of biomass and seeds yield have been evaluated. Different organic fertilizers, allowed by EU regulations conc…
N use and partitioning in coriander (Coriandrum sativum L.) after organic and conventional N fertilization
2010
In coriander, a well known spice herb, many studies concerning the effect of N fertilization have been conducted in special areas where the cultivation of such plant has a major importance, such as India. Limited information is available as concerns the response of coriander to N fertilization under Mediterranean climatic conditions, above all when organic N fertilizers (mandatory when organic cropping management is chosen) are used. This work refers about some observations realised from 2004 to 2006 by an experiment on organic and mineral N fertilization techniques in coriander, carried on in the experimental farm “Sparacia” (Cammarata, AG, Sicily). Similarly to what suggested for other sp…
Effects of organic and conventional N-fertilization on quality traits in coriander(Coriandrum sativum L.)
2010
In organic cropping management of Medicinal and Aromatic Plants, the best quality expression is crucial to gain satisfactory incomes. Coriander (Coriandrum sativum L.) is an annual herbaceous plant with a commercial value due to the typical scent of its fruits (commonly termed “seeds”), rich in a pale yellow oil (1-2% in small-sized types, 0.2-0.5% in large-sized ones). Several studies have been done for determining the composition of volatile fraction of Coriander, which was found to vary also as a consequence of cropping techniques, including nitrogen fertilization. In order to gain useful information about the effects, if present at all, of organic N fertilization on Coriander quality in…
COLTIVAZIONE DI PIANTE OFFICINALI ANNUALI DA SEME CON TECNICHE ECOCOMPATIBILI
2009
La Sicilia, caratterizzata da un’ampia variabilità pedo-climatica e da una notevole ricchezza di paesaggi naturali e tradizioni popolari, è sede ideale per la valorizzazione delle risorse vegetali di interesse officinale spontanee o spontaneizzate nell’area mediterranea, da introdurre o diffondere in coltivazione. Sulla base di questa premessa, allo scopo di valorizzare alcune specie officinali mediterranee, è stata condotta una sperimentazione pluriennale, che ha riguardato la coltivazione in pieno campo di tali specie, con tecniche ecocompatibili. Scopo della ricerca è stato quindi la messa a punto dei principali aspetti dell’agrotecnica applicabile ad alcune specie officinali di possibil…
Coltivazione di officinali con tecniche ecocompatibili
2006
Per valutare l'effetto di alcune pratiche agronomiche adoperate in biologico, su tre piante officinali mediterranee sono stati sperimentati fertilizzanti organici e pratiche di gestione non chimica della flora infestante
Api e pronubi selvatici nella produzione di Coriandrum sativum L. (Famiglia Apiaceae) in Sicilia occidentale
2009
Coriandrum sativum L. (Apiaceae - Umbelliferae) is an aromatic annual plant, subspontaneous in several Mediterranean countries. It is cultivated in various states of western Asia, North Africa and Europe. In Italy with the increment of immigration the request of coriandrum fresh state (grass cimicina) and powder to seeds are in increase. In Sicilian territory, for estimating the role of pollinators (wild pollinators and bees) in the increment of seeds production of Coriandrum sativum, a triennial surveying has been carried out, comparing three treatments: self-pollination, bees pollination and free pollination. The production of Coriandrum sativum obtained have been in the first year of 132…
Nitrogen fertilisation in coriander (Coriandrum sativumL.): a review and meta-analysis
2009
Nitrogen (N) fertilisation is one of the most important external inputs in assessing coriander seed yield and plant growth. Recent concerns related to the misuse of N fertilisers in agricultural environments, however, stress the opportunity for a fine-tuning of N management in order to optimise the use of this element, avoiding losses and reducing environmental hazards. In this study, some results from the literature concerning N fertilisation in coriander are reviewed and, by means of statistical analysis, an attempt is made to derive from them some general suggestions about practices of N fertilisation. In most cases examined, N fertilisation allowed a 10–70% increase in seed yields in co…
