BLURB FOR ETOCRecovery growth is a useful practice to increase total productivity of relay intercropping systems. Understanding phenotypic and physiological traits related to light interception and utilization changes and cultivars difference of soybean during the recovery growth period is important for further breeding and screening cultivars of soybean to improve the light interception and utilization in intercropping systems. AbstractRecovery growth is common in relay intercropping systems and is a useful practice to increase total productivity of these systems. A field experiment was conducted during 2014 –2016 to investigate the phenotypic and physiological traits related to light interception and utilization changes and cultivars difference of soybean during the recovery growth period. Two cropping patterns (maize–soybean relay strip intercropping (RSI), analogous soybean monoculture (CK)) and two soybean cultivars (shade-tolerantNandou12 and shade non-tolerantJiuyuehuang) were evaluated. During the co-growth period, the growth of both two soybean cultivars was suppressed and showed a series of shade avoidance traits. After maize harvest, the LAI and leaflet number of intercropped soybean exhibited rapid growth, the LAI ofNandou12 (3.09) andJiuyuehuang (1.32) recovered to 79% and 43% of corresponding CK level, respectively. Subsequently, final biomass ofNandou12 (3972.7  kg ha?1) andJiuyuehuang (2263.3  kg ha?1) recovered 85.7% and 52% of corresponding CK level, respect...
