Agricultural Sciences (AS) , 2012, DOI: 10.4236/as.2012.31007
Abstract: Agricultural systems based on crop rotations favour sustainability of cultivation and productivity of the crops. Wheat-forage crops rotations (annual winter binary mixture and perennial alfalfa meadow) combined with irrigation are the agronomical techniques able to better exploit the weather resources in Mediterranean environments. The experiment aimed to study the effect of 18 years of combined effect of irrigation and continuous durum wheat and wheat-forage rotations on productivities of crops and organic matter of topsoil. The experiments were established through 1991-2008 under rainfed and irrigated treatments and emphasized on the effect of irrigation and continuous wheat and wheat-forage crop rotations on water use efficiency and sustainability of organic matter. The effect of irrigation increased 49.1% and 66.9% the dry matter of mixture and meadow, respectively. Continuous wheat rotation reduced seed yield, stability of production, crude protein characteristics of kernel and soil organic matter. The yearly gain in wheat after forage crops was 0.04 t (ha·yr)-1 under rainfed and 0.07 t (ha·yr)-1 under irrigation treatments. The crude protein and soil organic matter of wheat rotations, compared to those of continuous wheat under rainfed and irrigated was increase in term of point percentage by 0.8 and 0.5 in crude protein and 5.1 and 4.4 in organic matter, respectively. The rotations of mixture and meadow under both irrigated treatments increased the point of percentage of organic matter over continuous wheat (9.3.and 8.5 in mixture and 12.5 and 9.5 meadow under rainfed and irrigation, respectively). Irrigation reduce the impact of weather on crop growing reducing water use efficiency (mean over rotations) for dry mater production (15.5 in meadow and 17.5 in mixture [L water (kg·dry·matter)-1 ]) and wheat seed yield. The effect of agronomic advantages achieved by forage crops in topsoil expire its effect after three years of continuous wheat rotation.

Italian Journal of Agronomy , 2011, DOI: 10.4081/ija.2006.359
Abstract: Annual forage crops have great importance for sustaining animal production in southern Italy. Knowledge of the performance of legume-grass associations under management similar to systems encountered in farm practice is essential for their effective exploitation of the available environmental resources. The purpose of this investigation was to estimate the effects of five cutting managements on the productivity and botanical composition of ten annual fodder crop mixtures in two Mediterranean environments. Ten ternary combinations of one grass (Avena sativa L., oat and Lolium multiflorum Lam., Italian ryegrass), one clover (Trifolium alexandrinum L., berseem; Trifolium incarnatum L., crimson and Trifolium squarrosum L., squarrosum) or burr medic (Medicago polymorpha L.) and common vetch (Vicia sativa L.) were compared in a field trial (split-plot design, 3 replicates) in two locations (Cagliari and Foggia, Italy) during the 2000-2001 growing season. The cutting treatments included a winter grazing simulation (G), a cutting only regime at early (EF) or late flowering (F) of legumes and a combination of treatments (GEF and GF). Plant density (no. m-2) prior to cutting, dry matter yield (g m-2) and botanical composition (%) were evaluated. Considerable differences were observed in the harvestable dry matter yields of mixtures among cutting treatments in both localities, with treatment F showing the higher values (787.1 and 415.7 g m-2 for Cagliari and Foggia, respectively). The forage species were able to compete and establish good growth during their initial phase in both localities. However, the botanical composition between the two sites differed considerably after the winter period. Particularly, at Foggia, grass dominance was a permanent feature of all treatments, and all the mixtures contained about 84% of grass. Italian ryegrass was the most representative species under all treatments in both sites. Mixtures with Italian ryegrass, crimson or berseem clovers and vetch showed higher adaptability to cutting treatments particularly at Cagliari. Our results showed that the forage species associations studied can be grown successfully under simulated grazing treatment during the winter season and under the double land-use system (integrated grazing and cutting) adopted at Cagliari. These treatments provide a reasonably economical means of assessing mixtures under diverse farming conditions. However, as a fraction of the plant population in swards of this experiment diminished over time, particularly at one site, the optimum of species present in these fora

Italian Journal of Agronomy , 2012, DOI: 10.4081/ija.2012.e41
Abstract: Agricultural systems based on crop rotation are beneficial to crop sustainability and productivity. Wheat-forage rotations combined with irrigation are the agronomic techniques best able to exploit Mediterranean environmental conditions. This paper describes a long-term field trial to ascertain the effect of combined irrigation and durum wheat-forage rotations on crop yield and soil chemical properties. The two forage crops: annual grass-clover winter binary mixture and perennial lucerne were carried out through 1991-2008 under rainfed and irrigated treatments. The experiments were used to highlight the effect of irrigation and wheat-forage crop rotations on water use efficiency (WUE) and sustainability of organic matter (OM) in topsoil. Irrigation increased the dry matter (DM) of annual binary mixture and lucerne by 49.1% and 66.9%, respectively. Continuous wheat rotation reduced seed yield (SY), stability of production, and crude protein (CP) characteristics of kernel and OM in topsoil. The yearly gain in wheat after forage crops was 0.04 t (ha yr)-1 under rainfed and 0.07 t (ha yr)-1 under irrigation treatments. The CP and soil OM of wheat forage crops rotations, compared with those of continuous wheat under rainfed and irrigated was a 0.8 and 0.5 % increase in CP and 5.1 and 4.4 in OM, respectively. The rotations of annual grass-clover winter binary mixture and lucerne meadow under both irrigated treatments increased the OM over continuous wheat (9.3 % and 8.5 in annual grass-clover winter binary mixture and 12.5 and 9.5 lucerne meadow under rainfed and irrigation, respectively). Irrigation reduced the impact of weather on crop growing, reducing water use efficiency (mean over rotations) for DM production (15.5 in meadow and 17.5 in annual grass-clover winter binary mixture [L water (kg DM)-1]) and wheat SY. However, the agronomic benefits achieved by forage crops in topsoil are exhausted after three years of continuous wheat rotation.
Effect of Manure vs. Fertilizer Inputs on Productivity of Forage Crop Models
Giovanni Annicchiarico,Giovanni Caternolo,Emanuela Rossi,Pasquale Martiniello
International Journal of Environmental Research and Public Health , 2011, DOI: 10.3390/ijerph8061893
Abstract: Manure produced by livestock activity is a dangerous product capable of causing serious environmental pollution. Agronomic management practices on the use of manure may transform the target from a waste to a resource product. Experiments performed on comparison of manure with standard chemical fertilizers (CF) were studied under a double cropping per year regime (alfalfa, model I; Italian ryegrass-corn, model II; barley-seed sorghum, model III; and horse-bean-silage sorghum, model IV). The total amount of manure applied in the annual forage crops of the model II, III and IV was 158, 140 and 80 m 3 ha ?1, respectively. The manure applied to soil by broadcast and injection procedure provides an amount of nitrogen equal to that supplied by CF. The effect of manure applications on animal feeding production and biochemical soil characteristics was related to the models. The weather condition and manures and CF showed small interaction among treatments. The number of MFU ha ?1 of biomass crop gross product produced in autumn and spring sowing models under manure applications was 11,769, 20,525, 11,342, 21,397 in models I through IV, respectively. The reduction of MFU ha ?1 under CF ranges from 10.7% to 13.2% those of the manure models. The effect of manure on organic carbon and total nitrogen of topsoil, compared to model I, stressed the parameters as CF whose amount was higher in models II and III than model IV. In term of percentage the organic carbon and total nitrogen of model I and treatment with manure was reduced by about 18.5 and 21.9% in model II and model III and 8.8 and 6.3% in model IV, respectively. Manure management may substitute CF without reducing gross production and sustainability of cropping systems, thus allowing the opportunity to recycle the waste product for animal forage feeding.

eSci Journal of Crop Production , 2012,
Abstract: Buffalo livestock represents profitable economy and sustainable farming activity in the Mediterranean area. The main claim of dairy farming is requirement of forage for sustaining buffalo feeding, particularly during lactation time. In land of EU Mediterranean environments, feeding forage is provided by cultivation of annual double sown crops. The most popular cropping system (referred as model) is based on irrigated Italian ryegrass and corn. The continuous cultivations of model, indeed the favourable economic and technical advantages, promotes constrains of biochemical parameters in topsoil and fitness of buffalo popularity in environments. Furthermore, survey of challenge for enlarging the popularity of buffalo breeding in harsh Mediterranean land, has been determined by cultivation of double sown models under rainfed condition. Sowing time, irrigation treatment and crops of the model influenced the production of dry matter (DM) and milk forage unit (MFU). The production of MFU ha-1 among models range from 3594 to 7438 in winter and 10256 to 15266 in spring under rainfed and 5042 to 9035 in winter and 11940 to 24003 in spring under irrigated. The total MFU ha-1 of winter-spring models range from 16962 to 30815 under irrigated and 13951 to 18097 under rainfed. Three years of continuous growing models reduced the beginning content of organic matter (OM), in winter and spring sown grasses models, by 4.3 g kg-1 under irrigated and 3.1g kg-1 under rainfed while the models based on annual legumes the reduction was lower (2.2 and 1.4 g kg-1, respectively). The experiments evidenced variability among models and singled out equipotent models able to satisfy the MFU, sustain biochemical soil parameters and allow opportunity to enlarge the fitness of buffalo in EU Mediterranean-type climate environments.

Abstract: Les auteurs proposent un cadre théorique nouveau qui articule les niveaux macro, méso et micro que la sociologie des migrations traditionnellement disjoint. Cette approche alternative s’appuie sur le concept de carrière, un classique en sociologie. Il propose le concept de carrières migratoires qui permettrait d’intégrer les effets des structures d’opportunités, les caractéristiques des individus et les effets des réseaux. From migration flow to migratory careers. Elements for a new theoretical perspective on contemporary mobility perspectiveThe authors present a new theoretical framework articulating macro, mess and micro levels of analysis, which often are disconnected in sociology of migration. This alternative approach rests on the classical sociological concept of career. The concept of migratory career integrates structures of opportunities, individual characteristic and networks to make sense of the migratory experience. De los flujos de la emigración a las carreras migrantes. Elementos para una nueva perspectiva teórica de los diferentes tipos de movilidad contemporáneaLos autores proponen un nuevo marco teórico que articula los niveles altos, medianos y peque os que la sociología de las migraciones a tradicionalmente disociado. Esta aproximación alternativa se basa en el concepto de carrera que concepto básico de la sociología y propone el concepto de carreras migratorias que permitiría integrar los efectos de las estructuras de oportunidades, las características de los individuos y los efectos de las redes.

Securitizing Area Insurance: A Risk Management Approach  [PDF]
Pasquale Lucio Scandizzo
Journal of Financial Risk Management (JFRM) , 2013, DOI: 10.4236/jfrm.2013.23009
Abstract: This paper examines the possibility of developing a risk management instrument by designing a financial security whose value is linked to the average revenue of a given area. This type of program is sufficiently general to be considered for any group of businesses that face production uncertainty. In agriculture, it has been proposed as an alternative to multiple peril crop insurance programs, as area yield, revenue or rainfall insurance in order to eliminate ex ante and ex post moral hazard. While most of the literature concentrates on the determination of value of the indemnity and the payment of such an insurance, this paper focuses on the fact that, unlike other forms of insurance, area insurance can be cast in the form of a hedging security and, as a consequence, rather than depending only on the demand for diversification (the beta of the Capital Asset Price Model), it makes possible a risk shifting strategy based on the heterogeneity of risk attitudes of the economic agents operating in a given area.
