“…The intercropping systems exert an outstanding advantage in grain yield and land productivity via interspecific facilitation 55 . In MS, resource use improves yield trade‐off by optimizing the crop configurations 9 . Relay intercropping has a greater impact on crop yield, but maize and soybean have different performances (Table 5).…”

“…55 In MS, resource use improves yield trade-off by optimizing the crop configurations. 9 Relay intercropping has a greater impact on crop yield, but maize and soybean have different performances (Table 5). Expanding interspecific row spacing contributes to an increase in soybean yield and a decline in maize yield.…”

“…8 Moreover, this relay-cropping technique has increased light energy and nitrogen (N) fertilizer utilization rates and has been widely adopted in China. 9 Many studies have reported the yield advantages in the intercropping systems, 8,10 and the mechanism regarding yield improvement is mainly associated with interspecific facilitation. 11 In cereal-legume intercropping systems, the productivity may be more affected by belowground than aboveground species interactions, and its advantage is reflected in the belowground part of the root interaction.…”

BACKGROUNDSoil is a key foundation of crop root growth. There are interactions between root system and soil in multiple ways. The present study aimed to further explore the response of root distribution and morphology to soil physical and chemical environment under maize (Zea mays L.) soybean (Glycine Max L. Merr.) relay strip intercropping (MS) An experiment was carried out aiming to examine the effects of nitrogen (N) applications and interspecific distances on root system and soil environment in MS. The two N application levels, referred to as no N application (NN) and conventional N application (CN), were paired with different interspecific distances: 30, 45 and 60 cm (MS30, MS45 and MS60) and 100 cm of monoculture maize and soybean (MM/SS100).RESULTSThe results demonstrated that MS45 increased the distribution of soil aggregates (> 2 mm) near the crop roots and maize soil nutrients status, which increased by 20.3% and 15.6%. Meanwhile, MS reduced soil bulk density, increased soil porosity and improved soil oxygen content. Optimization of the soil environment facilitated root growth. The MS45 achieved a better result on root distribution and morphology than the other configuration and also increased land productivity.CONCLUSIONRelay intercropped soybean with maize in interspecific row spacing of 45 cm, improved soil physicochemical environment, reshaped root architecture and optimized root spatial distribution of crops to achieve greater land productivity. © 2024 Society of Chemical Industry.
