Data, code and software to reproduce the article entitled "Modeling soil-plant functioning of intercrops using comprehensive and generic formalisms implemented in the STICS model"

<p>This is the data, code and software to reproduce the article entitled &quot; Modeling soil-plant functioning of intercrops using comprehensive and generic formalisms implemented in the STICS model&quot;. Here is a summary of the paper:</p> <p>The growing demand for sustainable agriculture is raising interest in intercropping for its multiple potential benefits to avoid or limit the use of chemical inputs or increase the production per surface unit. Predicting the existence and magnitude of those benefits remains a challenge given the numerous interactions between interspecific plant-plant relationships, their environment and the agricultural practices. Soil-crop models are critical in understanding these interactions in dynamics during the whole growing season, but few models are capable of accurately simulating intercropping systems.</p> <p>In this study, we propose a set of simple and generic formalisms for simulating key interactions in intercropping systems that can be readily included into existing dynamic crop models. This requires simulating important processes such as development, light interception, plant growth, N and water balance, and yield formation in response to management practices, soil conditions, and climate. These formalisms were integrated into the STICS soil-crop model and evaluated using observed data of intercropping systems of cereal and legumes mixtures, including Faba&nbsp;bean-Wheat, Pea-Barley, Sunflower-Soybean, and Wheat-Pea mixtures. We demonstrate that the proposed formalisms provide a comprehensive simulation of soil-plant interactions in various types of bispecific intercrops. The model was found consistent and generic under a range of spring and winter intercrops (nRMSE = 25% for maximum leaf area index, 23% for shoot biomass at harvest, and 18% for yield).</p> <p>This is the first time a complete set of formalisms has been developed and published for simulating intercropping systems and integrated into a soil-crop model. With its emphasis on being generic, sufficiently accurate, simple, and easy to parameterize, STICS is well-suited to help researchers designing <em>in silico</em> the agroecological transition by virtually pre-screening sustainable, manageable intercrop systems adapted to local conditions.</p> <p>&nbsp;</p> <p>&nbsp;</p> <p>&nbsp;</p>

Metadata related to Optimized Intercropping System (NCBI PRJNA928765)

<p><strong>The Sahel of W Africa is a climate change hotspot, where soil degradation and recurring drought significantly reduce agricultural productivity. Erratic rainfall, exacerbated by climate change, t contributes to ongoing and future food insecurity in this region. The staple crop, pearl millet (Pennisetum glaucum), is grown by subsistence farmers during the rainy season without fertilizer or irrigation (conditions also desired for US domestic biofuel cultivation). Indigenous farming practices demonstrate one solution: where farmers intercrop with an native woody shrub (Guiera senegalensis), millet drought resilience - and crop yields - are dramatically increased. One mechanism of this beneficial interaction: shrubs perform hydraulic redistribution of water to surface soil, assisting crops through growing-season drought periods. Additionally, the moister and more nutrient rich soils under the shrub canopy harbor a distinct and active microbial community; this work examines the role of these microbes in aiding the millet. We have&nbsp; characterized this potential in partnership with the Joint Genome Institute (JGI, project number 505730) to metagenomically sequence the millet rhizo- and endo-sphere communities, with and without shrub intercropping, in long-term experimental plots in Senegal. Using the framework of known plant-microbe beneficial interactions we are analyzing metagenomes for genes and genomes related to plant growth promotion, and metagenomic data is publicly available via NCBI under PRJNA928765. Here, we publish soil chemical, plant biomass, and PLFA data obtained from the OSS during the&nbsp; 2019 sampling season and corresponding 2020 dry season. </strong></p>

Responses of agricultural weed community in a corn-soybean intercrop

This dataset was created as a part of an experiment which used a soybean-corn intercrop system for examining how the community structure of agricultural weeds changes with fertilization and with the identity of the crop species. The composition of the weed flora in intercrops was compared with the weed flora of the respective sole crops, with and without fertilization. The experiment was conducted at Kellogg Biological Station (KBS) in southwestern Michigan, USA, in 1993.

Overyielding is accounted for partly by plasticity and dissimilarity of crop root traits in maize/legume intercropping systems

<p><span>Positive biodiversity-productivity relationships have been found in biodiversity field experiments of grassland, forestry, and other natural terrestrial ecosystems, where diversity effects were separated by complementarity (CE) and selection effects (SE). However, we know little about how CE and SE are related to root traits and root dissimilarity.</span></p> <p><span>A four-year field experiment was carried out with a split-plot design, where main plot was four nitrogen (N) applications (N0, N1, N2, N3) and five cropping systems (maize (</span><span><em>Zea mays</em> </span><span>L.</span><span>)/soybean (</span><span><em>Glycine max</em> </span><span>L. Merrill.</span><span>), maize/peanut (</span><em><span>Arachis hypogaea</span></em> <span>L.</span><span>) intercropped and the corresponding monocultures) with three replicates. Roots were sampled in the N0 and N2 treatments in two years. Intercropping effects were analyzed based on grain yield for four years and roots were sampled down to 60 cm depth, and analyzed with morphological parameters at different crop growth stages in two years.</span></p> <p><span>Intercropping significantly increased grain yield and aboveground biomass in both intercropping systems under all N treatments. The partitioning of the net intercropping effects showed that yield advantage in intercropping was due to a positive CE under the N0 treatment, and to a positive SE with N application.</span></p> <p><span>Maize showed greater root morphological plasticity than the legumes did, with greater changes in root length density (RLD), root weight density (RWD) and total root surface (TS) in intercropping than in monoculture. Intercropped maize occupied a larger soil space, while lateral RLD distribution of legumes was decreased by maize. The RLD, RWD, and TS of intercropped maize were constant or increased in later growth stages. SE showed a significantly positive relationship with root dissimilarity. Principal component analysis showed mean root depth and specific root length of legumes drove the positive CE in the absence of N fertilization. </span></p> <p><span>Root dissimilarity determined by maize explained the selection effects in overyielding. Complementarity effects under N0 were closely associated with specific root traits such as mean root depth and specific root length.

Temporal stability of productivity is associated with complementarity and competitive intensities in intercropping

Year to year stability in crop production is a crucial aspect of feeding a growing global population. Evidence from natural ecosystems shows that increasing plant diversity generally increases the temporal stability of productivity; however, we have little knowledge of the mechanisms by which diversity affects stability. In fact, understanding the drivers of stability is a major knowledge gap in our understanding of biodiversity and ecosystem function in general. We varied resource inputs into crop monocultures and intercropping of maize/pea and maize/rapeseed for three years in field experiments to create a wide range of values for temporal stability, complementarity effects, selection effects, competition, and facilitation. We correlated whole-system temporal stability in productivity with these values and the stability of competitively subordinate species and competitively dominant species in the intercrops. We then used structural equation modeling (SEM), which combines complex path models with latent variables, to estimate how interspecific interactions for water, nitrogen, and phosphorus affected the relationships between stability and these values. Intercropping treatments did not increase stability, but the wide range of stability created by our experiments allowed us to explore the relationship of many factors with stability. Complementarity correlated positively with the temporal stability of grain yield and aboveground biomass, suggesting that either facilitative interactions or niche partitioning shifted over time in ways that promoted stability. Furthermore, the temporal stability of total productivity of intercropping relied most on the stability of more productive species. However, facilitation tested by relative interaction index (RII) independently did not correlate with stability, but the temporal stability of the whole system increased as the competitive effects of competitively dominant species (pea and rapeseed) on competitively subordinate species (maize) decreased, and was highest when these competitive effects were virtually zero. SEM indicated that as competition for soil nitrogen from competitively dominant species on competitively subordinate species decreased, the overall temporal stability of whole-system aboveground biomass increased. This stability then led to greater stability in grain production. Our findings indicate that complex shifts in complementarity and competitive intensities are likely to be key mechanisms that maintain temporal stability in species-diverse agriculture, and potentially in natural systems.

Data from: The interplay of intercropping, wildflower strips and weeds in conservation biological control and productivity

<p>Diversifying agroecosystems is instrumental to reduce pesticide use in agriculture. While different diversification practices have the potential to reduce pests, their integration at the agroecosystem level and the evaluation of their multifunctional effects remain limited. Through a two-year field experiment conducted in Germany, we tested whether associating intercropping (faba bean-wheat, followed by breadseed poppy-barley) with pluriannual wildflower strips strengthens the biological regulation of aphid pests and weeds, and enhances cropping system productivity. The contribution of flowering weeds to conservation biological control was also analysed. Aphid colonization rates, but also predator colonization and predation rates, on bean and poppy were consistently lower in intercropping compared to sole cropping. Associating wildflower strips to intercropping enhanced aphid predation in bean-wheat intercropping, and further reduced aphid colonization at 10 m distance from the flower strip but not at 20 m in poppy-barley intercropping. Weed biomass was strongly reduced in intercropping compared to sole crop bean and poppy, and did not significantly affect bean and poppy yields in intercropping. The cover of one flowering weed species, <em>Matricaria recutita</em>, was negatively correlated to aphid colonization rate and positively correlated to predation rate in bean-wheat intercropping. In poppy-barley intercropping, <em>M. recutita</em> flowers were visited more often by predatory hoverflies in plots adjacent to wildflower strips. Finally, land equivalent ratio, measuring land-use efficiency, was consistently higher than 1, and the highest in bean-wheat intercropping associated to wildflower strips. The study shows that intercropping is key to control multiple pests and enhance land-use efficiency, and demonstrates that associating wildflower strips to intercropping can strengthen biological control and cropping system productivity. Flowering weeds, maintained at an acceptable level through intercropping, turn out to be relevant functional biodiversity in interacting with wildflower strips to support natural enemies for conservation biological control.</p>

Interspecific interactions regulate plant reproductive allometry in cereal-legume intercropping systems

<p>1. Calls for the application of ecological principles in agriculture have gained momentum. Intercropping systems are designed by growing two, or more, annual crop species in the same field, aiming for a better resource use efficiency. However, assembly rules for their design are lacking. Notably, it is unknown whether species performances are maximized during both the vegetative and reproductive phases given the sensitivity of reproductive allocation rules to resource limitation. Interestingly, ecological theory provides expectations regarding putative invariance of plant reproductive allometry (PRA) under non-limiting conditions for plant growth. Here we examined whether and how PRA changes in response to plant-plant interactions in intercropping systems, which can inform both ecological theory and the understanding of the functioning of intercropping systems.</p> <p>2. We analyzed a dataset of 28 field cereal-legume intercropping trials from various climatic and management conditions across Western Europe. PRA was quantified in both mixing and single-species situations.</p> <p>3. PRA was positively impacted in specific management conditions, leading to a greater increase in yield for a given increase in plant size. Variations in PRA were more beneficial for legumes grown in unfertilized mixtures, which explains their use as a key component in actual intercropping systems. The response for cereals was similar but less pronounced in magnitude, and was greater under resource limiting conditions. Focusing on intercropping conditions, hierarchical competition (indicated by biomass difference between intercropped species) appears as a strong driver of the reproductive output of a given species.</p> <p>4. Synthesis and applications. PRA behaves in crop species in the same way as it does in wild species. However, contrary to theoretical expectations about an overall invariance of PRA, we highlighted taxon-specific and context-dependent effects of plant-plant interactions on PRA. This systematic deviation to PRA expectations could be leveraged to cultivate each species up to its reproductive optimum while accounting for the performance of the other, whether farmer's objective is to favor one species or to reach an equilibrium in seed production. Sowing density and cultivar choice could regulate the biomass of each component, with specific targets derived from allometric relationships, aiming for an optimal reproductive allocation in mixtures.21-Jul-2021</p>

Original data for for intercropped maize experiments, root barrier experiments in intercropped maize, and unilateral shading experiments

<p><span>Intercropping improves resource utilization and yield; however, shading causes a decline in yield. Under wide-narrow-row maize-soybean intercropping, maize plants are subjected to weak unilateral illumination and exhibit high photosynthetic performance. However, the mechanism regulating photosynthesis under unilateral weak light remains unknown. Therefore, we conducted an experiment with different planting configurations and two controlled environments to investigate photosynthesis, sugar metabolism, and photosynthate allocation in unshaded and shaded leaves under weak light. All three experiments detected an increase in the net photosynthetic rate (<em>Pn</em>) of unshaded leaves on one side with an increase in the level of shade on the other side leaves. On the contrary, the concentration of sucrose and starch and the number of starch granules in the unshaded leaves decreased with increased shading due to the transfer of abundant <sup>13</sup>C into the grains. However, sink loss with ear removal reduced the <em>Pn</em> of unshaded leaves, limiting their ability to transport sugar. Detailed analysis showed that intense unilateral shade (40% to 20% normal light) reduced grain yield (37.6% to 54.4%) but not mild unilateral shade (60% normal light). We further found that in unshaded leaves, <em>Agpsl, Bmy, </em>and<em> Mexl</em>-like significantly influenced sucrose and starch metabolism, while <em>Sweet13a</em> and <em>Sut1</em> were crucial for sugar export. <em>Sps1, Agpsl, </em>and<em> Sweet13c</em> were crucial for sugar metabolism and export in shaded leaves. Thus, our study confirmed that under unilateral illumination, unshaded leaves, which transported photosynthates to the ear, contributed significantly to the grain filling and reduced sugar concentration, resulting in a higher photosynthetic performance, while the shaded leaves synthesized fewer photosynthates, primarily for their growth and development. We, therefore, propose a narrow-row spacing (40 cm) that provides appropriate unilateral shade (60% normal light) and limits yield reduction in a wide-narrow-row intercropping system. </span></p>
