Effects of continuous and rotational grazing of different forage species on ewe milk production

2012

Abstract The aim of this research was to evaluate the effects of continuous and rotational grazing of different forage species on milk production in ewes. The forage species were chicory (Cichorium intybus L.), a mixture of oat (Avena sativa L.) and berseem clover (Trifolium alexandrinum L.), and sulla (Hedysarum coronarium L.). Forty ewes were divided into 5 groups, and subjected to one of the following treatments: continuous grazing on chicory, continuous grazing on the mixture, continuous grazing on sulla, rotational grazing on the mixture, or rotational grazing on sulla. Among the species continuously grazed, chicory showed a lower biomass than the mixture, or sulla. Ewes grazing chicor…

Weed seedbank size and composition in a long-term tillage and crop sequence experiment

2015

Summary Knowledge of the effects of agricultural practices on weed seedbank dynamics is essential for predicting future problems in weed management. This article reports data relative to weed seedbank structure after 18 years of continuous application of conventional tillage (CT, based on mouldboard ploughing) or no tillage (NT) within three crop sequences (continuous wheat, WW; wheat–faba bean, WF; and wheat–berseem clover, WB). Tillage system did not affect the size of the total weed seedbank, but altered both its composition and the distribution of seeds within the soil profile. In particular, the adoption of CT favoured some species (mainly Polygonum aviculare), whereas the continuous u…

Durum wheat yield uncertainty under different tillage management practices and climatic conditions

2019

Abstract In the field of conservative agriculture, no-till (NT) management has been receiving increasing interest, with 45 million ha of land under no-till management in 1999 to 155 million ha in 2014. Up until now, no-till has only been observed to perform better under rainfed conditions, especially in dry climates mainly because the reduced tillage system retains more soil moisture. However, the adoption of alternative agricultural practices (NT) can be improved only if uncertain and consequent assumption of risk is well known and accepted. For these reasons, the aim of this research is (i) to define durum wheat suitability under NT soil management in terms of yield success probability an…

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.

Arts. 34-40 EIR

2016

The comments on Arts. 34-40 of EU Regulation 2015/848 deal with opening of secondary insolvency proceedings. These comments systematically tackle the prerequisites required for the opening of secondary insolvency proceedings, the relationship between main and secondary proceedings and the duties of cooperation that are put on the courts and the insolvency practitioners of both main and secondary proceedings. A particular attention is devoted to the introduction of the so-called “Undertaking to Avoid the Opening of Secondary Insolvency Proceedings” (Art. 36).

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…
