Plant response to irrigation with saline water in a Sicilian vineyard: results of a three-year field investigation
This paper reports the results of a three-year field investigation carried
out in a vineyard located in Sicily (Mazara del Vallo, Trapani) within
the framework of the Project: Evolution of cropping systems as affected by climate change (CLIMESCO). Research investigated soil-plant
response to irrigation performed with water having two different salinity
levels; soil hydrological characteristics, soil salinity, crop transpiration and stomatal conductance were measured in field plots. The
results proved that crop transpiration and stomatal conductance were
significantly affected by soil salinity conditions (expressed as electrical conductivity of the soil saturated water extract). A significant reduction in both the physiological parameters was observed in the treatment irrigated
with water having higher salinity (electrical conductivity equal to
1.6 dS m–1) as compared to the treatment irrigated with water of lower salinity (electrical conductivity equal to 0.6 dS m–1)
Monitoring Soil Salinisation as a Strategy for Preventing Land Degradation: A Case Study in Sicily, Italy
Combination schemes for turning point prediction
We propose new forecast combination schemes for predicting turning points of business cycles. The combination schemes deal with the forecasting performance of a given set of models and possibly providing better turning point predictions. We consider turning point predictions generated by autoregressive (AR) and Markov-Switching AR models, which are commonly used for business cycle analysis. In order to account for parameter uncertainty we consider a Bayesian approach to both estimation and prediction and compare, in terms of statistical accuracy, the individual models and the combined turning point predictions for the United States and Euro area business cycles
