Uso di alcuni estratti vegetali come bio-erbicidi
2014
Le infestanti competono con le piante coltivate per la luce, gli elementi nutritivi, l'acqua e lo spazio, e influenzano fortemente le produzioni agrarie sia sotto l'aspetto quantitativo che qualitativo. Normalmente le infestanti riescono ad assorbire e utilizzare l'acqua e gli elementi nutritivi più rapidamente ed efficacemente delle colture principali, accrescendosi più velocemente di queste, fino, talvolta, ad inibirne del tutto lo sviluppo. Nel corso del tempo, alcune infestanti hanno sviluppato meccanismi di resistenza agli erbicidi comunemente utilizzati. Questa acquisizione, unitamente alla necessità di reperire soluzioni al problema della gestione delle infestanti anche in condizioni…
Cultivation of Dill (Anethum graveolens L.) with Different Row Arrangements
2011
Dill (Anethum graveolens L.) is an annual plant from the Umbelliferae. Although in cookery also sprouts and tender leaves are used, the drug from dill is represented by the scented fruits (“seeds”), largely used for flavouring conserved foods and liqueurs, but also by the herbal and cosmetic industry. In this work, we present the results of a trial performed in Sicily, putting under comparison four different row arrangements: CR30 (continuous rows 30 cm apart), CR60 (continuous rows 60 cm apart), CR90 (continuous rows 90 cm apart) and TR (twin rows with a distance of 30 cm inside and 60 cm between twin rows). The plant population on the row (12 plants m-1) was constant and according the row…
Effect of Sowing Time on Coriander Performance in a Semiarid Mediterranean Environment
2006
In semiarid environments, time of sowing is one of the most important factors influencing seed yields. For coriander (Coriandrum sativum L.), the most commonly recommended cropping technique is spring sowing (March–April), since the optimum soil temperature for seed germination ranges between 20 and 23 °C, and the crop shows a remarkable sensitivity to frost and cold. In many semiarid areas of southern Italy, however, the occurrence of prolonged dry periods in summer and spring does not allow for the scheduling of summer crops without irrigation. However, the generally mild winter temperatures and the typical rainfall distribution, which is mostly concentrated over the winter months, could …
Prove di coltivazione di Calendula (Calendula officinalis L.) in ambiente semi-arido
2008
Inside the family Asteraceae, Marigold is one of the most relevant species bearing some herbal interest. The evaluation of the bio-agronomical and yield response of the species to the field cropping conditions, especially when a low input cropping technique is applied, is the base for its full exploitation. With this objective, a long-term research activity has been started out by the DAAT (Department of Environmental and Land Agronomy) of the University of Palermo in the experimental farm “Sparacia” (Cammarata – AG – Sicily), performing observations on Marigold plants managed with a minimum recourse to external technical inputs (nor pesticides neither chemical weeding, and a light (50 kg h…
Cultivation of Dill (Anethum graveolens L.) with different row arrangements

Being constant the plant population on row (12 plants m-1), the plant density per unit area changed …
Nonchemical weeding of medicinal and aromatic plants
2013
International audience; Medicinal and aromatic plants are major crops of domestic and industrial interest. Medicinal and aromatic plants are increasingly organically grown to enhance profitability. However, the presence of weeds may lead to a decrease in both yield and quality. Therefore, nonchemical methods of weed control are needed. In this study, mechanical weeding, flaming, stale seedbed, and biodegradable mulch were tested from 2003/2004 to 2006/2007 on coriander, fennel, and psyllium. Biomass and seed yield were measured. The biomass of weeds remaining at harvest was also measured. Results show a high sensitivity of coriander, fennel, and psyllium crops to the presence of weeds. Stal…
Multifunctional role of medicinal and aromatic plants: Perspectives and constraints
2008
Multifunctionality is one of the newest claims addressed to agricultural practices, that are nowadays requested to overpass their classical role to furnish food and fibers for human needs, also addressing to the fulfillment of other human necessities, such as to accomplish recreational services and to give a contribute for environmental safeguard. Medicinal and aromatic plants (MAPs) may be an important tool for the advancement of agricultural practice towards multifunctionality: they represent a mean for crop (and economical) diversification, contribute to land valorization by means of their aesthetical value, may fit into integrated agro-industrial pathways, may give raw matters and inter…
Sustainable production of fennel and dill by intercropping
2008
Intercropping is claimed to be one of the most significant cropping techniques in sustainable agriculture, and much research and many reviews attribute to its utilization a number of environmental benefits, from promoting land biodiversity to diversifying agricultural outcome. In this sense, intercropping is thought to be a useful means of minimizing the risks of agricultural production in many environments, including those typical of under-developed or marginal areas. In order to validate this hypothesis in a representative area of the semiarid Mediterranean environment, we evaluated the possibility of growing dill and fennel, both belonging to the family Apiaceae, in temporary intercroppi…
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…
