“…Chickpea was able to mobilize soil organic P and leave more inorganic P available to the intercropped wheat or maize in low-P sandy soils (Li et al, 2003a;Li et al, 2004). Analytical studies on P mobilization from different P pools in soil need to separate the rhizosphere of each intercropped species from the bulk soil to allow for accurate P fractionation and measurement of changes in the amounts of the various pools (Makoi et al, 2010;Hinsinger et al, 2011;Betencourt et al, 2012;Tang et al, 2014;Dissanayaka et al, 2015).…”

Background Phosphorus (P), iron (Fe) and zinc (Zn) are essential elements for plant growth and development, but their availability in soil is often limited. Intercropping contributes to increased P, Fe and Zn uptake and thereby increases yield and improves grain nutritional quality and ultimately human health. A better understanding of how intercropping leads to increased plant P, Fe and Zn availability will help to improve P-fertilizer-use efficiency and agronomic Fe and Zn biofortification.Scope This review synthesizes the literature on how intercropping of legumes with cereals increases acquisition of P, Fe and Zn from soil and recapitulates what is known about root-to-shoot nutrient translocation, plant-internal nutrient remobilization and allocation to grains.Conclusions Direct interspecific facilitation in intercropping involves below-ground processes in which cereals increase Fe and Zn bioavailability while companion legumes benefit. This has been demonstrated and verified using isotopic nutrient tracing and molecular analysis. The same methodological approaches and field studies should be used to explore direct interspecific P facilitation. Both niche complementarity and interspecific facilitation contribute to increased P acquisition in intercropping. Niche complementarity may also contribute to increased Fe and Zn acquisition, an aspect poorly understood. Interspecific mobilization and uptake facilitation of sparingly soluble P, Fe and Zn from soil, however, are not the only determinants of the concentrations of P, Fe and Zn in grains. Grain yield and nutrient translocation from roots to shoots further influence the concentrations of these nutrients in grains.

“…Comparing solid barriers with mesh barriers between the root species of intercropped species showed that the beneficial effect of faba bean on maize was not due to seasonality or complementary use of rooting space but due to the release of organic acids and protons. However, such facilitation has mainly been reported for pot experiments (Betencourt et al 2012). Only a small proportion of soil phosphorus is available to crops, and so legumes with greater capability to mobilize part of the large pool of unavailable phosphorus in the soil might improve the availability of this resource for the benefit of cereals in crop associations (Hinsinger et al 2011).…”

Provisioning services, such as the production of food, feed, and fiber, have always been the main focus of agriculture. Since the 1950s, intensive cropping systems based on the cultivation of a single crop or a single cultivar, in simplified rotations or monocultures, and relying on extensive use of agrochemical inputs have been preferred to more diverse, self-sustaining cropping systems, regardless of the environmental consequences. However, there is increasing evidence that such intensive agroecosystems have led to a decline in biodiversity as well as threatening the environment and have damaged a number of ecosystem services such as the biogeochemical nutrient cycles and the regulation of climate and water quality. Consequently, the current challenge facing agriculture is to ensure the future of food production while reducing the use of inputs and limiting environmental impacts and the loss of biodiversity. Here, we review examples of multiple cropping systems that aim to use biotic interactions to reduce chemical inputs and provide more ecosystem services than just provisioning. Our main findings are the identification of underlying ecological processes and management strategies related to the provision of pairs of ecosystem services namely food production and a regulation service. We also found gaps between ecological knowledge and the constraints of agricultural practices in taking account of the interactions and possible trade-offs between multiple ecosystem services as well as socioeconomic constraints. We present guidelines for the design of multiple cropping systems combining ecological, agricultural, and genetic concepts and approaches.

“…Many trials were conducted in order to investigate influence of different species in intercrops, especially cereals and legumes, such as maize and beans (Fischler et al 1999), maize and peanut (Xiong et al 2013), wheat and chickpea (Banik et al 2006, Betencourt et al 2012, barley and pea (Launay et al 2009). …”

“…Comparing to sole crops, intercrops are able to provide many benefits. It was found that intercropping may increase yields (Zhang et al 2011), income (Yildirim andGuvenc 2005, Singh et al 2013), availability of plant-nutrients (Betencourt et al 2012), reduce the occurrence of diseases (Gomez-Rodriguez et al 2003), suppress weeds (Sharma and Banik 2013), and decrease the demands for fertilization and use of pesticides (Carruthers et al 2000). It can be a helpful tool for soil remediation (Sun et al 2011) and reduction of wind erosion (Chen et al 2010).…”

The impact of intercropping green bean (Phaseolus vulgaris L.) with red beet (Beta vulgaris L. var. rubra) and radish (Raphanus sativus L.), two non-legume plants, on the plants' yields, as well as the effect on occurrence and enumeration of microorganisms in the rhizosphere was studied. The intercrop efficacy evaluation, using Land equivalent ratio, revealed values above 1.0 for all intercropped treatments. Diversity of rhizobia from green bean nodules under different intercropping and fertilizing conditions was observed. On the basis of morphological and biochemical characteristics, 67 out of 158 isolates from green bean roots were selected as rhizobia (42.4%), confirmed by detection of 780 bp nifH gene fragments in nifH-PCR, and then clustered in 27 phenotype patterns. Production of exopolysaccharide succinoglycan was observed in 23 rhizobial isolates, while 6 were detected to solubilize tricalcium phosphate. Screening of genetic diversity using (GTG) 5 -PCR fingerprinting showed presence of six different patterns on the 92% similarity level.
