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…
The Real Effect of Financial Crises in the European Transition Economies
2010
Working Paper GATE 2009-20; International audience; The aim of this work is to assess the impact of financial crises on output for 11 European transition economies (CEECs). The results suggest that financial crises have a significant and permanent effect, lowering long-term output by about 17 percent. The effect is more important in smaller countries, with relative higher dependence on external financing, and in which the banking sector noticed more important financial disequilibria. We also found that fiscal policy measures have been the most efficient tools in dealing with the crises, while the role of monetary policy instruments has been rather blinded. Exchange rate resulted to be more …
Vertisols and cambisols had contrasting short term greenhouse gas responses to crop residue management
2020
In sustainable agriculture crop residues management should consider the interactions between soil and residue properties, which can affect the decomposition and global greenhouse gases (GHGs) emission. Through a laboratory experiment, we investigated the effect of the management (incorporation and surface placement) of wheat and faba bean residues on their decomposition and CO2, CH4 and N2O emissions from two soils, a Chromic Vertisol and an Eutric Cambisol. In the Vertisol, wheat residues increased the CO2 emission more than faba bean when left on the surface whereas no differences among residues were observed when incorporated. In the Cambisol, faba bean emitted more than wheat when left …
Effects of cropping systems and irrigation on the bio-agronomic and quality response of industrial tomato (Lycopersicon esculentum mill.).
2012
This paper shows the results obtained in 2009 of a study carried out by the Dipartimento di Agronomia Ambientale e Territoriale (D.A.A.T.) aimed at identifying and evaluating various low input cropping systems for industrial tomato varieties, a traditional farming crop in Sicily. The tests were carried out on the Sparacia experimental farm (Cammarata AG, 37°37’N, 13°42’E). The farm is located in a sub-arid area with average rainfall levels of approx. 500 mm and average min/max temperatures of 9 and 21°C. The soils, typical of soil types in the area, are Eutric Vertisols. A split-split plot design with three repetitions was adopted and the following variables were studied: 1) management of c…
Performance of a Pilot-Scale Constructed Wetland and Medium-Term Effects of Treated Wastewater Irrigation of Arundo donax L. on Soil and Plant Parame…
2021
On marginal lands in the Mediterranean basin, giant reed (Arundo donax L.) represents one of the most interesting perennial crops due to high levels of biomass production. Considering periodic water shortage during the summer months in this area, the reuse of treated wastewater (TWW) would seem to be a good opportunity for the growth of the species. The aim of this study was to assess the medium-term effects of irrigation using freshwater (FW) and TWW on soil characteristics and growth in giant reed plants. TWW was obtained from a pilot-scale horizontal subsurface flow constructed wetland system (HSSF CWs) with a total surface area of 100 m2. A split-plot design for a two-factor experiment …
