Alternate Identifier:

DOI PLACE HOLDER

Abstract:

Data and R code associated with a greenhouse study investigating the influence of water stress on growth, root traits, and biomass of rye and crimson clover seedlings grown separately or together. Data were collected in the Dr. Inge P. Stafford Greenhouse of Dickinson College (Carlisle PA, USA) in June 2021.

Data Entities
Data Table Name:	Dry weight
Description:	The table contains total dry biomass and biomass per plant for each species, water treatment, species number, and replicate.
Data Table Name:	Survival rate
Description:	The table provides the survival rate by species, water treatment, species number, and replicate. Survival proportion was calculated from comparing number of survived seedlings at the termination of the experiment to the pot's density.
Data Table Name:	Crimson Clover's growth score
Description:	The table provides daily growth score of crimson clover by replicate, water stress, species number, and phase (i.e., water treatment and recovery). Growth score was determined by the emergence of cotyledons, first true leaf, first trifoliate leaf, second trifoliate leaf, etc.; each stage was equivalent to one point.
Data Table Name:	Rye's growth score
Description:	The table provides daily growth score of rye by replicate, water stress, species number, and phase (i.e., water treatment and recovery). One point of growth score indicated a visible leaf collar.
Data Table Name:	Crimson Clover's normalized root scan outputs
Description:	This table contains the outputs of Crimson Clover root scans from RhizoVision Explorer after normalization by the number of plants per pot. Variables are organized by water stress, species number, replicate, number of plants per pot.
Data Table Name:	Rye's normalized root scan outputs
Description:	This table contains the outputs of Rye root scans from RhizoVision Explorer after normalization by the number of plants per pot. Variables are organized by water stress, species number, replicate, number of plants per pot.
Data Table Name:	Crimson Clover's raw root scan outputs
Description:	This table contains the outputs of Crimson Clover root scans from RhizoVision Explorer. Variables are organized by water stress, species number, replicate, number of plants per pot.
Data Table Name:	Rye's raw root scan outputs
Description:	This table contains the outputs of Rye root scans from RhizoVision Explorer. Variables are organized by water stress, species number, replicate, number of plants per pot.
Other Name:	dryweight_cc_anova
Description:	Code to analyze the effect of water stress treatment, species number, and their interaction on per-plant dry biomass of crimson clover seedlings.
Other Name:	dryweight_r_glm
Description:	Code to analyze the effect of water stress treatment, species number, and their interaction on dry biomass of rye seedlings.
Other Name:	dryweight_totalbiomass
Description:	Code to analyze the effect of water stress treatment, species number, and their interaction on total biomass of crimson clover and rye grown separately or together.
Other Name:	growth_rate
Description:	Code to analyze the effect of water stress treatment, species number, and their interaction on growth rate of crimson clover and rye.
Other Name:	root_PCA_v2
Description:	Code for a principal component analysis to understand the influence of water stress and species number on the root morphology of crimson clover and rye.
Other Name:	root_analysis
Description:	Code to analyze the effect of water stress treatment, species number, and their interaction on key root traits in crimson clover and rye. Traits included total root length (both species), average root diameter (crimson clover), and maximum root diameter (rye).
Other Name:	survival_rate
Description:	Code to analyze the effect of water stress treatment, species number, and their interaction on seedling survival of crimson clover and rye.

Abstract:

Climate change models predict increasing precipitation variability in the mid-latitude regions of Earth, generating a need to reduce negative impacts of these changes on crop production. Despite considerable research on how cover crops support agriculture in a changing climate, understanding is limited of how climate change influences the growth of cover crops. We investigated the early development of two common cover crop species – crimson clover (Trifolium incarnatum L.) and rye (Secale cereale L.) – and hypothesized that growing them in mixture would ameliorate stress from drought or waterlogging. This hypothesis was tested in a 25-day greenhouse experiment, where the two factors (species number, water stress) were fully crossed in randomized blocks, and plant responses were quantified through survival, growth rate, biomass production, and root morphology. Water stress negatively influenced the early growth of these two species in contrasting ways: crimson clover was susceptible to drought while rye performed poorly under waterlogging. Per-plant biomass in rye was always greater in mixture than in monoculture, while per-plant biomass of crimson clover was greater in mixture under drought. Both species grew longer roots in mixture than in monoculture under drought, and total biomass of mixtures did not differ significantly from the more-productive monoculture (rye) in any water condition. In the face of increasingly variable precipitation, growing crimson clover and rye together has potential to ameliorate water stress, a possibility that should be further investigated in field experiments.
