“…Mixed cropping is the simultaneous cultivation of two or more crops on the same field. Especially legume/non-legume species mixtures have been proposed to achieve a higher per area production and profitability and higher yield stability with less or no external inputs ( Bedoussac et al, 2015 ; Raseduzzaman and Jensen, 2017 ; Wendling et al, 2017 ; Viguier et al, 2018 ). Good pairs of complementary species have already been identified, such as combinations of corn ( Zea mays L.) with cowpea ( Vigna unguiculata L., Ofori and Stern, 1986 ), with common bean ( Phaseolus vulgaris L., Hoppe, 2016 ; Starke, 2018 ), and with faba bean ( Vicia faba L., Li et al, 2020 ), as well as small grain cereals such as barley ( Hordeum vulgare L., Hauggaard-Nielsen et al, 2001 ) with pea ( Pisum sativum L.) or wheat ( Triticum aestivum L.) with faba bean ( Agegnehu et al, 2006 ) or with lentil ( Lens culinaris MEDIK., Viguier et al, 2018 ).…”

Advances in Breeding for Mixed Cropping – Incomplete Factorials and the Producer/Associate Concept

et al. 2021

Mixed cropping has been suggested as a resource-efficient approach to meet high produce demands while maintaining biodiversity and minimizing environmental impact. Current breeding programs do not select for enhanced general mixing ability (GMA) and neglect biological interactions within species mixtures. Clear concepts and efficient experimental designs, adapted to breeding for mixed cropping and encoded into appropriate statistical models, are lacking. Thus, a model framework for GMA and SMA (specific mixing ability) was established. Results of a simulation study showed that an incomplete factorial design combines advantages of two commonly used full factorials, and enables to estimate GMA, SMA, and their variances in a resource-efficient way. This model was extended to the Producer (Pr) and Associate (As) concept to exploit additional information based on fraction yields. It was shown that the Pr/As concept allows to characterize genotypes for their contribution to total mixture yield, and, when relating to plant traits, allows to describe biological interaction functions (BIF) in a mixed crop. Incomplete factorial designs show the potential to drastically improve genetic gain by testing an increased number of genotypes using the same amount of resources. The Pr/As concept can further be employed to maximize GMA in an informed and efficient way. The BIF of a trait can be used to optimize species ratios at harvest as well as to extend our understanding of competitive and facilitative interactions in a mixed plant community. This study provides an integrative methodological framework to promote breeding for mixed cropping.

“…For instance, reduced N fertilizer input at early co-growth stage in maize/pea intercropping improves N2 fixation of intercropped pea, and N fertilization at late co-growth stage increases the recovery growth of intercropped maize (Hu et al 2016;Hu et al 2017). The relatively high and stable crop productivity and economic benefits of intercropping are attractive to farmers (Ngwira et al 2012;Pelzer et al 2012;Viguier et al 2018). However, management of two crops in one field is more complex than that of a single crop, and markets may require high purity standards for harvested product that may be difficult to achieve if crops are harvested simultaneously with existing machinery (Bedoussac et al 2015;Viguier et al 2018).…”

“…In conclusion, this meta-analysis presents two diverging syndromes of agricultural production by intercropping and suggests that these allow harvesting 16% to 29% more grain per hectare while using 19% to 36% less fertilizer per unit output than conventionally done in the monocrops of modern industrialized agriculture. Higher yield and lower inputs might mean greater profit to farmers (Ngwira et al 2012;Pelzer et al 2012;Viguier et al 2018), lowered environmental impacts (Whitmore and Schröder 2007;Pelzer et al 2012) and a more stable and secure food supply (Rusinamhodzi et al 2012;Raseduzzaman and Jensen 2017).…”

Phosphorus acquisition and yield gain in intercropping: empirical studies and meta-analyses

View full text Add to dashboard Cite

Intercropping, growing two or more crop species in the same field, is a practice that can contribute to ecological intensification of agriculture. Intercropping has been shown to increase productivity in low phosphorus (P) soils compared to sole crops. The ecological mechanisms underlying these benefits mainly include complementarity and facilitation with respect to resource acquisition. The contribution of these mechanisms to the yield benefit of intercropping probably depends on crop species traits, soil nutrient availability and agronomic practices. This thesis aims to contribute to the design of intercropping systems for improved P acquisition and yield gain by testing the resource partitioning hypothesis (dissimilarity in P acquisition traits among plant species leads to enhanced P uptake by mixtures of crop species compared to sole crops), and by quantifying the absolute yield gain of intercrops and the effect of agronomic practices. It presents results from empirical studies and meta-analyses.It appeared that the conditions under which the P resource partitioning hypothesis can be tested are limited. The tested crop species had inconsistent abilities to access the sparingly soluble Ca-bound P, phytate P, P-coated Fe(hydr)oxide, and competitive inequality between them largely determined the interaction. In a pot experiment with low P soils containing a mixture of organic and inorganic P sources, complementarity and facilitation did not result in increased P uptake by species mixtures, because P uptake was also affected by the competitive equality of species in the mixture. In a field experiment on a low P soil, complementarity and facilitation with respect to P uptake occurred in millet/chickpea relay strip intercropping, but they were not the main drivers for overyielding. In the subsequent meta-analysis on intercropping at the field level, the absolute yield gain of intercropping was mainly attributed to a positive complementarity effect, an outcome of any mechanism reducing competition. This positive complementarity effect was related to complementarity in using resources at different times caused by a relay sequence in the sowing and harvesting of intercropped species. The temporal complementarity in using resources plays an important role in competitive relaxation and hence overyielding. On a global level, there was a set of coordinated management factors rather than a single factor that drove the yield gain of intercropping, resulting in two contrasting syndromes of production in intercropping. The first syndrome was a high input -high output strategy that is maize-based with species arranged in relay strips and with high fertilizer input. The second syndrome was a low inputlow output strategy that is legume-based and arranged in simultaneous full mixtures or alternate row intercrops with low fertilizer input. Both intercropping strategies saved 16-29% land and 19-36% fertilizer compared to monocultures grown under the same management as the intercrop.To conclude, there was no evidence for the resourc...
