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…
Effects of Organic and Chemical N-fertilization on Yield and Morpho-biological Features in Coriander (Coriandrum sativum L.).
2009
Although MAPs are subjected to a growing interest (from growers, transformation industries, public and private institutions), a full introduction of such species into the Mediterranean cropping systems still needs the pointing out of many aspects. An important task concerns some aspects of cropping technique, whose definition could allow these crops to optimize the yields (both from the qualitative and the quantitative point of view), also allowing the best exploitation of land resources. One of the most crucial aspects is linked to plant fertilization, above all with Nitrogen. The trial that we report the results of has been performed in 2003- 04 and 2004-05 with the aim to study the effec…
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…
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…
MAPs in Sicily: cultivation, uses, and potentiality
2013
In Sicily, MAPs have been used and cultivated for centuries, with many uses ranging from the preparation of fresh or stored food items, flavoring of foods and beverages, home-made human or animal therapy or even aesthetical purposes. Many of them grow spontaneously into such areas, and are claimed to play a significant role inside land biodiversity. The widespread belief that only under “natural” conditions MAPs find their optimum quality features has driven in many cases to their uncontrolled collection from the wild, and as a result many of them are nowadays at a risk of extinction. The field cropping of such spontaneous species could play an important role in safeguarding biodiversity, a…
Cultivation Trials of Dill (Anethum graveolens L.) with Different Row Arrangements

Prove di coltivazione di Hypericum perforatum in ambiente mediterraneo
2014
La possibilità di introduzione dell’iperico negli ordinamenti colturali mediterranei richiede la definizione di numerosi aspetti relativi alla tecnica di coltivazione, il cui approfondimento permetterebbe di ottimizzare le rese sia sul piano della quantità che della qualità, rispettando al contempo il criterio della massima efficienza nell’uso delle risorse produttive. Accessioni di H. perforatum ottenute da seme proveniente da tre diverse aree italiane (nord-Trento, centro-Siena e sud-Agrigento) sono state coltivate sia in pieno campo che in vaso. La raccolta delle sommità fiorite è stata effettuata tra giugno e luglio dell’anno successivo a quello della semina (massima fioritura). Contemp…
Cultivation of wild medicinal species: opportunities and constraints.
2008
In medicinal plants (MPs), the transition from “discovery” to “cultivation” stage involves a decreasing recourse to their collection from the wild, accompanied by an increasing interest in their suitability into agricultural or silvicoltural cropping systems. Collecting from the wild, although is surely the oldest method for obtaining MPs, allows to satisfy very limited needs and is hardly suitable to an industrial use, because: 1) gathering from the wild does not guarantee the quantitative and qualitative uniformity that nowadays are well defined requirements of the consumers. Spontaneous yields are difficult to quantify and sometimes may be overestimated, above all when random and unfores…
