“…Growing cereals in association with legumes offer the best opportunity for conserving soil fertility by returning more amounts of organic matter to the soil, thus improving its cation exchange capacity and physical conditions (Bodena 2018;Iqbal et al 2018). They also improve soil fertility through deep rooting, nitrogen fixation, leaf shedding ability, and mobilization of insoluble soil nutrients to soluble form (Begam et al 2020;Layek et al 2018;Maitra et al 2021). The existing evidence shows that the mixture of exudates released by legumes can play a critical role in modifying the chemical composition and transforming unavailable P, Ca, and Fe in the rhizosphere into available resources through solubilization or chelation (Duchene et al 2017;Latati et al 2019).…”

The deficiencies of micronutrients known as hidden hunger are severely affecting more than one-half of the world’s population, which is highly related to low bioavailability of micronutrients, poor quality diets, and consumption of cereal-based foods in developing countries. Although numerous experiments proved biofortification as a paramount approach for improving hidden hunger around the world, its effectiveness is highly related to various soil factors, climate conditions, and the adoption rates of biofortified crops. Furthermore, agronomic biofortification may result in the sedimentation of heavy metals in the soil that pose another detrimental effect on plants and human health. In response to these challenges, several studies suggested intercropping as one of the feasible, eco-friendly, low-cost, and short-term approaches for improving the nutritional quality and yield of crops sustainable way. Besides, it is the cornerstone of climate-smart agriculture and the holistic solution for the most vulnerable area to solve malnutrition that disturbs human healthy catastrophically. Nevertheless, there is meager information on mechanisms and processes related to soil-plant interspecific interactions that lead to an increment of nutrients bioavailability to tackle the crisis of micronutrient deficiency in a nature-based solution. In this regard, this review tempted to (1) explore mechanisms and processes that can favor the bioavailability of Zn, Fe, P, etc. in soil and edible parts of crops, (2) synthesize available information on the benefits and synergic role of the intercropping system in food and nutritional security, and (3) outline the bottlenecks influencing the effectiveness of biofortification for promoting sustainable agriculture in sub-Saharan Africa (SSA). Based on this review SSA countries are malnourished due to limited access to diverse diets, supplementation, and commercially fortified food; hence, I suggest integrated research by agronomists, plant nutritionists, and agroecologist to intensify and utilize intercropping systems as biofortification sustainably alleviating micronutrient deficiencies.

“…T 5 (2.29) had the maximum CGR at 60-90 DAS followed by T 4 (2.26) and T 6 (2.25) and T 1 had minimum CGR (2.12). Canopies of their neighbouring plants were exposed to sunlight, which increased their NAR [26]. Maximum MsEY was noted in (T 5 ) followed by T 4 and T 6 i.e., 11663.36 kg ha -1 , 11152.52 kgha -1 and 10969.55 kgha -1 respectively.…”

The current study evaluated the impact of intercropping Cowpea and Moong bean on Maize yield and its constituent parts. Nine different treatments were used in the experiment viz., (T1) sole Maize, (T2) sole Cowpea, (T3) sole Moong bean, (T4) Maize + Cowpea (1:1), (T5) Maize + Cowpea (1:2), (T6) Maize + Cowpea (1:3), (T7) Maize + Moong bean (1:1), (T8) Maize + Moong bean (1:2) and, (T9) Maize + Moong bean (2:1) in a randomized block design with three replications in Kharif season. The findings showed that intercropped plants had greater potential and produced higher values for the majority of the studied criteria, including plant height, chlorophyll meter reading (SPAD) number of cobs plant-1, number of rows cob-1, number of grains row-1, 100-grain weight, and straw and grain yields Intercrop’s seed yields were less in intercropped treatments than sole Maize. (T5) Maize + Cowpea (1:2) was best treatment having highest yield (5915.83 kg ha-1), maximum LER (1.8) and MEY (kg ha-1) (11663.36). This clearly demonstrated the advantages of intercropping Maize with legumes. This is because the leguminous crops can provide additional nutrients to the Maize crop through biological nitrogen fixation (BNF). Additionally legumes can improve the declined soil productivity by enhancing the overall soil conditions like chemical, biological, and physical. The increased availability of nitrogen and enhancement in soil physical, chemical and biological properties can improve Maize growth, leading to higher yield. Additionally it boosts soil conservation by providing more ground cover than mono-cropping.

“…Intercropping of cereals and legumes has been reported to conserve soil and water in some landscapes and provide stable yields (Melkamu, 2023). Smallholder farmers often grow cereal-legume intercrops due to legumes' ability to adapt to disintegrating soils and in uence soil health (Begam et al, 2020). Legumes can x nitrogen from the atmosphere in the soil which increases fertility and reduces the soil nutrients for replenishment (Meena et al, 2015b).…”

The purpose of the study is to evaluate the effectiveness of intercropping systems cereals (Durum/hard Wheat)-legume (Cicer arietinum) on phosphorus (P) acquisition, pH soil variation, and the variation in enzymatic activity, through root-induced processes in semi-arid soil of South Tunisia. Split plot experiments with triplicate repetitions were carried out in southern Tunisia during two years of field (2020–2021 and 2021–2022). These comprise mono-crop chickpea (CK) and mono-crop durum wheat/ wheat durum (DW/WD), durum wheat intercropping (DW-C), and chickpea intercropping (CK-C). At the complete vegetation stage of durum wheat and chickpea, three soil samples were carried in layer surface for each experimental plot. For the analyses of soil, the P total, Olsen-P, phytase, acid phosphatases, and pH were carried out in the experiment. The obtained findings show a significant amelioration in P total contents in DW-C by 28% and 26% to DW, and 94% and 93% than BS during the two years of field experiment (2020–2021 and 2021–2022) respectively. Furthermore, the Study reported an increase of Olsen-P in the rhizosphere of DW-C by around 5%, 42% than DW, and 36%, 65% to bulk soil (BS) during the two-year experiment. Likewise, these results revealed an increase in A-Phase rates in the DW-C rhizosphere during the two agricultural seasons (2020–2021 and 2021–2021), of approximately 26%, 8% than DW and 33%, 67% than BS respectively. As well as the phytase activity indicated an increase in the DW-C rhizosphere by 67% and 69% than in BS and only by 8% and 7% than in DW for the two seasons (2020–2021 and 2021–2021). Indeed, the rhizosphere acidification of rhizosphere was found very much high in CK-C (0.63 pH units and 0.55 units lower than in the BS).
