Design of an innovative system for precision beekeeping

2019

The innovative technologies of precision agriculture can be applied today to different productive sectors of agriculture in order to optimize crop production and to improve the quality of the final products. One of these is beekeeping, a very important sector both from an environmental and a production standpoint. The production of honey depends on many factors, some of which are environmental factors such as temperature, relative humidity and wind. The aim of this study was the design of a Precision Apicolture System (PAS) platform for monitoring and controlling the main environmental factors, both inside and outside the hive, in order to assess their influence on the honey daily productio…

Effects of intraspecific competition on growth and seed yield of contrasting sulla genotypes.

2010

Sulla (Hedysarum coronarium L.) is a short-lived perennial legume native to the Mediterranean basin, where it is grown extensively as a 2-year forage crop. Seed is often obtained as a secondary product from second-year crops established to produce forage. Very little information is available on seed yield capacity in the first year of the crop cycle and on the influence of agronomical techniques on the reproductive process. The present study aimed to evaluate the effect of intraspecific competition on dry matter accumulation (both in epigeic organs and in taproots) and seed production in the first year of a crop cycle for two contrasting genotypes. Two field trials were carried out in a Med…

Long‐Term Durum Wheat‐Based Cropping Systems Result in the Rapid Saturation of Soil Carbon in the Mediterranean Semi‐arid Environment

2016

Climate, soil physical–chemical characteristics, land management, and carbon (C) input from crop residues greatly affect soil organic carbon (SOC) sequestration. According to the concept of SOC saturation, the ability of SOC to increase with C input decreases as SOC increases and approaches a SOC saturation level. In a 12-year experiment, six semi-arid cropping systems characterized by different rates of C input to soil were compared for ability to sequester SOC, SOC saturation level, and the time necessary to reach the SOC saturation level. SOC stocks, soil aggregate sizes, and C inputs were measured in durum wheat monocropping with (Ws) and without (W) return of aboveground residue to the…

Pheno-morphological, agronomic and genetic diversity among natural populations of sulla (Hedysarum coronarium L.) collected in Sicily, Italy

2010

Sulla (Hedysarum coronarium L.) is a short-lived perennial forage legume that plays a key role in cereal-based systems in semi-arid Mediterranean regions, particularly in organic production and low-input oriented agriculture. In Sicily, the species is widespread both as a wild and cultivated plant. The present study assessed the phenotypic and genetic variation among natural populations of sulla collected from different environments throughout Sicily and analysed how the patterns of phenotypic diversity varied according to the environmental parameters of each collection site. Two commercial varieties and two Sicilian agro-ecotypes were also included in the study as controls. Principal compo…

Biological nitrogen fixation of some landraces of sulla (Hedysarum coronarium) in Mediterranean environment

Effects of feeding green forage of sulla (Hedysarum coronarium L.) on lamb growth and carcass and meat quality.

2012

The nutritional effects of sulla (Hedysarum coronarium L.) forage containing condensed tannins (CT) on growth of lambs, and carcass and meat quality were investigated. Thirty-two male Comisana lambs aged 100 ± 8 days weighing 19.0 ± 2.8 kg were fed fresh forage of sulla or CT-free annual ryegrass (Lolium multiflorum Lam. subsp. Wersterwoldicum) for 49 days until slaughter; in addition, each lamb was supplied with 200 g/days of concentrate. Eight lambs per diet had been previously treated with anthelmintic drugs to remove nematode parasites. Measurements of BW and feed intake, and counts of faecal nematode eggs were made. Carcass parameters were recorded after slaughter, and tissue component…

Collezione, caratterizzazione e valutazione agronomica di popolazioni siciliane di sulla (Hedysarum coronarium L.)

2008

L’attività di ricerca è stata rivolta principalmente alla raccolta, caratterizzazione e valutazione delle attitudini agronomiche di popolazioni siciliane di sulla, al fine di colmare la carenza di informazioni sulla variabilità genetica esistente in Sicilia nell’ambito di questa specie e, eventualmente, di identificare genotipi utilizzabili come materiale di base per l’avvio di programmi di miglioramento genetico. L’articolazione delle ricerche ed i dispositivi adottati sono stati i seguenti: i) valutazione del livello di diffusione della specie in Sicilia, principalmente in aree non coltivate, attraverso una campagna di raccolta di seme programmata sull’intero territorio isolano; ii) carat…

Green Composites Based on Hedysarum coronarium with Outstanding FDM Printability and Mechanical Performance

2022

The addition of natural scraps to biodegradable polymers has gained particular interest in recent years, allowing reducing environmental pollution related to traditional plastic. In this work, new composites were fabricated by adding 10% or 20% of Hedysarum coronarium (HC) flour to Poly (lactic acid) (PLA). The two formulations were first produced by twin screw extrusion and the obtained filaments were then employed for the fabrication of composites, either for compression molding (CM) or by fused deposition modeling (FDM), and characterized from a morphological and mechanical point of view. Through FDM it was possible to achieve dense structures with good wettability of the filler that, on…
