Model prediction of xylem water potential in growing tomato plant under heterogeneous growing conditions dataset

Description

This data repository contains data from greenhouse and tomato growth monitoring. In 2019, 2020, 2023, 2024 data were collected at Proefcentrum Hoogstraaten (Voort 71, 2328 Hoogstraten, Belgium) during GROW! project (https://www.grensregio.eu/projecten/grow). In 2021 and 2022 data were collected at KU Leuven bioengineering greenhouse (Celestijnenlaan 300, 3001 Heverlee). The repository consists of: • environmental measurements (Environment folder): temperature, relative humidity, light irradiation and/or photosynthetic active radiation (PAR); • tomato plant measurements (Plant folder): stem length, stem diameter, stem fresh weight, stem dry weight, leaf area, leaf fresh weight, leaf dry weight, stem water potential and weight change for transpiration. Fruit growth: diameter, fresh weight, dry weight. Each folder contains file Info.xlsx explaining recorded variables, units and sensors used. The dataset is part of linked publication "Model prediction of xylem water potential in growing tomato plant under heterogeneous growing conditions"

Steps to reproduce

Data were collected in the years 2019 - 2024 from greenhouse tomato production with conditions set according to commercial tomato production standards. In 2019, 2020, 2023, 2024, data were collected from Proefcentrum Hoogstraten (Meerle, Belgium) in 2021 and 2022 from greenhouses of KU Leuven (Heverlee, Belgium). T and RH data were measured by central weather station (Electronic Measuring Box, Priva, De Lier, The Netherlands) just above the crop canopy in the middle of each compartment and T and RH sensors (SHT41 Smart Gadget, Sensirion, Stäfa, Switzerland) placed at 3 vertical levels (1 m spacing in between). In 2020, two light sensors (SQ 300, Apogee, Santa Monica, USA) measuring photosynthetically active radiation (PAR) were placed at the top of the canopy. In 2021 and 2022, pyranometers (PYR) (SP-110-SS, Apogee Instruments, Logan, U.S.A.) were used to measure total radiation inside the greenhouse. Attached are weather measurements from the nearest meteorological station of Royal Meteorological Institute (RMI). The number of nodes (leaf, flower, truss), stem growth, stem diameter were measured weekly (unless specified differently) on plants by non-destructive measurements. Stem fresh weight, stem dry weight, leaf area, leaf fresh weight, leaf dry weight and stem water potential were measured at specified time points. Transpiration was followed over a week for selected plants in 2022. Water potential was measured using a pressure chamber on leaves that were covered and shaded 30 minutes prior to measurement. Fruit growth was followed from anthesis till ripe. Three trusses were sampled weekly to measure diameter, fresh weight and dry weight.
