Aiming at improved knowledge on water use, productivity and irrigation scheduling of processing pea, the soil water balance model SIMDualKc was calibrated and validated using field data observed in two farmers’ fields in a wet and a dry year. The model uses the dual crop coefficient approach for partitioning crop evapotranspiration into crop transpiration and soil evaporation. Calibration was performed by minimizing differences between measured and simulated soil water content with a root mean s...

The AquaCrop model was parameterized and evaluated using data relative to supplemental irrigated vining pea for industry using observations in farmers’ fields located in the Ribatejo region, Portugal. Data refers to field observations relative to leaf area index (LAI), soil water content, biomass and final yield relative to two contrasting rainfall years, 2011 and 2012, a wet and a dry year, respectively. LAI data were used to parameterize the canopy cover (CC, %) curve. Results showed that afte...

The previously field calibrated approach of coupling the SIMDualKc soil water balance model with the Stewart’s water-yield model was used to assess the impacts of alternative sowing dates and irrigation schedules upon malting barley (Hordeum vulgare L. cv. Publican) yields. To properly support modelling, the study was based upon field observations in a farmers’ field during 2012 and 2013 crop seasons, respectively a dry and a wet year. The study aimed at assessing alternative sowing dates and ir...

The mountainous massif of Sico, in the centre of Portugal, is an extensive area composed of calcareous Jurassic formations. Hillside calcareous soils, with high pH, present chemical restrictions to support plant growth and are subjected to important erosion processes leading to their degradation if not protected by vegetation. In a first year of study some soil physicochemical characteristics have been measured in some geo-referenced locations of a larger design experiment and an exploratory spa...

Nitrogen (N) is a major fertilizing element for plants. The distribution of N in legumes is influencing the efficiency of the next crop. Nitrogen storage in legumes is actually estimated by N fixation in shoots, whereas there is little knowledge on the contribution of roots and nodules to legume N and soil N. Here, we studied the contribution of roots and nodules of grain and pasture legumes to plant N and soil N in Mediterranean fields. Experiments were run under rainfed conditions for a 2-year...

Soils in Southern Europe are often shallow and susceptible to erosion. Proper soil management with conservation of crop residue is crucial to preserve nutrients in Mediterranean agro-ecosystems. We studied the short-term effects of contrasting tillage on potential N availability and microbial activity and microbial counts in a sandy soil amended with white lupine residue. Tillage favoured N release at highest temperature, but microbial activity was lowered at this temperature. Immobilization was...

Abstract One experiment lasting for two years was carried out at Pegoes (central Portugal) to estimate the impact of mature white lupine residue ( Lupinus albus L.) on yield of fodder oat ( Avena sativa L. cv. Sta. Eulalia) as the next crop in rotation, comparing with the continuous cultivation of cereal, under two tillage practices (conventional tillage and no-till) and fertilized with five mineral nitrogen (N) rates, with three replicates. Oat as a first crop in the rotation provided more N to...

Abstract In order to better understand the role of crop residues in soil protection, soil organic matter, nutrient conservation and cycling in Mediterranean agro-ecosystems, it is necessary to develop research since only limited information is available. Few studies have compared the decomposition rates of legume and cereal residues in the field, particularly under soil conservation practice with respect to residue management. In disturbed and undisturbed Portuguese light soils amended with matu...
