Abstract
  • It is a common irrigation practice of fruit growers to fine-tune timing and amount of water gifts to achieve higher productivity and better quality. This requires different irrigation strategies during different phenological stages. Moreover, irrigation management should be adapted to different cultivars, besides weather and climate. Finally, after harvest, water gifts may be reduced to the minimum level required for plant survival. Adaptation to climate change adds an additional dimension to the challenge of designing and applying optimal irrigation scheduling. This challenge can be met by a combination of experiments and modelling on the water balance of the soil plant atmosphere system. The objective of this paper is to evaluate the magnitude and significance of differences in the modelled soil water deficit (as a function of time) when taking into account the specific phenological cycle of each cultivar versus a generic assessment for each species. We present the results of a case study on Peach cultivars in an area of the Po Valley where fruit crops are intensively grown (Imola). We evaluated for several Peach cultivars the soil water deficit and the irrigation requirement taking into account the shifting in phenological phases in response to air temperature. This analysis is performed taking into account the variability of soils. A reference (1961-90) and future (2021-2050) climate were considered. Reference climate has been produced applying a spatial statistic approach on ground observations. Future climate scenario has been generated from statistical downscaling of general circulation models (AOGCM). The results consist of daily time series of maximum and minimum temperature, and daily rainfall on a 35km*35km grid. The grid node located near Ravenna is the most representative of the local climate within the study area. The phenological development in reference and future climate is modeled using phase - specific thermal times and variety specific thermal requirements for peach cultivars. These requirements were estimated using phenological observations over several years in Emilia Romagna region and scientific literature. We calculated the dates of start and end of rest completion, flowering, fruit development and ripening stages, from late autumn through late summer. Then, a mechanistic model of water flow in the soil-plant-atmosphere continuum was used to describe the hydrological conditions in each phenological phase in response to climate and irrigation. Crop-specific input data and model parameters were estimated on the basis of local experiments and of scientific literature and assumed to be generically representative of the specie. Soils hydrological properties of the study area were determined from HYPRES pedo-transfer functions. Upper boundary conditions were derived from the two climate scenarios. Statistics on time series of soil water deficit were compared with control numerical experiments where both inter-cultivars differences and the shifting of phenological stages were neglected.
