“…Growth was usually slow during the fi rst year, while root system establishment was developing. These fi ndings agree with those of Tani et al ( 2006 ) and Loewe ( 2003 ), who reported best performances in cherry trees grown along with accessory trees, especially N-fi xing species. Therefore, the observed height growth in Chile was greater than in 8 year-old agroforestry plantations in Languedoc, France, where annual height growth ranged between 0.31 and 0.69 m year −1 (Balandier and Dupraz 1999 ).…”

Agroforestry, the purposeful growing of trees and crops in interacting combinations, began to attain prominence in the late 1970s, when the international scientifi c community embraced its potentials in the tropics and recognized it as a practice in search of science. During the 1990s, the relevance of agroforestry for solving problems related to deterioration of family farms, increased soil erosion, surface and ground water pollution, and decreased biodiversity was recognized in the industrialized nations too. Thus, agroforestry is now receiving increasing attention as a sustainable landmanagement option the world over because of its ecological, economic, and social attributes. Consequently, the knowledge-base of agroforestry is being expanded at a rapid rate as illustrated by the increasing number and quality of scientifi c publications of various forms on different aspects of agroforestry.Making full and effi cient use of this upsurge in scientifi c agroforestry is both a challenge and an opportunity to the agroforestry scientifi c community. In order to help prepare themselves better for facing the challenge and seizing the opportunity, agroforestry scientists need access to synthesized information on multi-dimensional aspects of scientifi c agroforesty.The aim of this new book-series, Advances in Agroforestry, is to offer state-of-the art synthesis of research results and evaluations relating to different aspects of agroforestry. Its scope is broad enough to encompass any and all aspects of agroforestry research and development. Contributions are welcome as well as solicited from competent authors on any aspect of agroforestry. Volumes in the series will consist of reference books, subjectspecifi c monographs, peer-reviewed publications out of conferences, comprehensive evaluations of specifi c projects, and other book-length compilations of scientifi c and professional merit and relevance to the science and practice of agroforestry worldwide.More information about this series at

In Chile, indigenous forests (mostly Nothofagus sp. and Acacia caven ) and plantations of fast-growing exotic species cover 13.5 and 2.4 million ha, respectively. The latter consists principally of Pinus radiata and Eucalyptus sp., but also include cherry ( Prunus avium ), poplar ( Populus sp.), and walnut ( Juglans regia ). The main silvopastoral systems that have been established in the temperate zone of the country, excluding arid, semiarid and Patagonian regions, are in: (1) an old Nothofagus forest in the foothills of the Andes, (2) a second-growth "Roble" ( Nothofagus obliqua ) forests of the Andes, with the objectives of rejuvenating the overmature forests, and evaluating the quantity and quality of pasture that is sown under different tree coverages. The Pinus radiata -based silvopastoral systems are the most common system adopted by smallscale agroforestry producers in the Mediterranean Chile in diverse environments from semiarid to humid zones. Furthermore, because of the expanding markets for pine nuts and timber of several hardwood species, several experimental trials were established in the past 20 years between the Valparaiso and Los Lagos regions, including exotic species such as cherry, walnut, poplar and stone pine ( Pinus pinea ). Through regular income from the sale of diverse woody and non-woody forest products, these innovative silvopastoral

“…Nell'ultimo ventennio, sia in America che in Euro pa, sono stati realizzati diversi studi sugli impianti misti (Kelty 2006, Piotto 2008) e su impianti di latifo glie consociate con piante azotofissatrici che hanno messo in evidenza risultati soddisfacenti e, in deter minati casi, nettamente superiori in termini di pro duttività, portamento delle piante e diffusione degli agenti patogeni, rispetto agli impianti monospecifici (Friedrich & Dawson 1984, Schlesinger & Williams 1984, Le Tacon et al 1988, Campbell & Dawson 1989, Buresti et al 1993, Frattegiani 1993, Buresti & Fratte giani 1994, Cutini et al 1997, Buresti & De Meo 1999, Pedlar et al 2006, Tani et al 2006.

IntroduzioneL'attuazione del Regolamento CEE 2080/92 ha de terminato, in Italia e in Europa, una crescente diffu sione di impianti di arboricoltura finalizzati alla pro duzione di legname di pregio. Nel nostro paese il noce comune (Juglans regia L.) è stata non solo la spe cie più utilizzata ma anche quella che ha suscitato maggiori interessi (Giannini & Mercurio 1997). Il suo utilizzo è avvenuto principalmente in monocoltura e, in misura più contenuta, in consociazione. Per conso ciazione si intende la coltivazione contemporanea, per l'intero ciclo colturale o parte di esso, di due o più specie, distinguibili in specie principali, destina te a garantire la maggior parte del reddito della pian tagione, e in specie secondarie o di accompagnamen to, introdotte per favorire la specie principale e/o Abstract: Effects of thinning and mixed plantations with Alnus cordata on growth and efficiency of common walnut (Juglans regia L.). Results about the effects of thinning and mixed plantations with Italian alder (Alnus cordataLoisel.) on growth and efficiency of common walnut (Juglans regia L.) plantations for wood production are reported. The study, carried out for six years on sixteen year old plantations, compared three theses: pure common walnut plantation (pure common walnut); 50% common walnut -50% Italian alder plantation; 25% common walnut -75% Italian alder plantation. Beyond annual surveys of girth at breast height, total height, stem volume and biomass, several variables, useful to describe canopy and foliage characteristics such as leaf area index (LAI), leaf biomass and photosynthetic active radiation below the canopy, were recorded. Data collected allowed to compare growth at individual and whole stand level, to calculate the net assimilation rate (NAR) and to compare the growth efficiency of the three theses. Mixed plantations performed results si gnificantly higher than the pure plantation in terms of growth, LAI and leaf biomass both before and after experimental thinning. With reference only to common walnut, growth in mixed plantations was higher than the pure plantation with differences ranging from +40% to +100%. More relevant differences among pure common walnut, 50% common walnut and 25% common walnut at canopy and foliage characteristics were respectively. Results accounted for a general positive ef fect of Italian alder as accessory tree species on growth and efficiency of mixed plantations, mainly due to the good performances induced in common walnut trees. Such performances were enabled by the good eco logical integration between the two species and by the positive effects of N-fixing activity of Italian alder. Ex perimental thinning applied, although heavy, did not biased the dynamics observed before thinning both in pure and mixed plantations. In addition, they had positive effects on common walnut growth and especially on radial increment, a very important matter being common walnut the target species with a very apprecia ted and valuable wood.
