“…Moreover, it has been suggested that spray applications of pesticides against FAW are inefficient due to their high levels of pesticide resistance, as they are resistant to 47 active ingredients in pesticides [ 42 , 43 . Cultural control of FAW in the form of intercropping with legume species such as Vicia faba (broad bean) and Medicago sativa (alfalfa) has been explored in maize and have been shown to reduce FAW herbivory through deterrence and attraction of natural predators and parasitoids [ 44 , 45 ]. FAW is predominantly a seasonal pest, but with climate change heating winter temperatures, we expect that their activity will be increased as well [ 41 ].…”

Soybean ( Glycine max ) is the most important plant protein source, and Fall Armyworm (FAW, Spodoptera frugiperda) is considered a major pest. This study aimed to examine the impact of FAW feeding on soybean accessions that vary in their water use efficiency (WUE) traits, by examining FAW growth and life history parameters along with plant growth response to pest damage. Soybean accessions were grown in a greenhouse and exposed to FAW larval feeding for 48 h at three different soybean growth stages: V3, R3, and R6. The growth and development of the FAW and soybeans were monitored. Results showed that faster wilting soybean accessions grow taller and have more leaves than slower wilting accessions, but yield was higher in slower wilting soybean accessions. FAW experienced the highest mortality on mid-stage (R3) soybean plants, but they gained the least mass on early stage (V3) soybean plants. These results can assist in better understanding plant insect-interactions at different life stages in both soybean and FAW with implications for management.

“…Niveum (FON), which leads to the plant death and reduced watermelon yield ( Ren et al, 2008 ). In agroecosystems, intercropping is beneficial for plant growth ( Xiao et al, 2013 ), increases production ( Kermah et al, 2017 ; Wu et al, 2022 ; Zhu et al, 2022 ), and suppressess some soil-borne diseases, such as Fusaria , Cylindrocladium parasiticum , Phytophthora capsici , Verticillium dahliae ( Gao et al, 2014 ; Yang et al, 2014 ; Xu, Wang & Wu, 2015a ; Li et al, 2019 ; Zhou et al, 2023 ). Nevertheless, the intricate process through which intercropping inhibits soil-borne infections involves root exudates ( Fu et al, 2015 ; Li et al, 2019 ), enzymes ( Li et al, 1999 ; Lv et al, 2023 ), soil microorganisms ( Zhou et al, 2023 ), and pathogen density ( Ren et al, 2008 ; Xu, Wang & Wu, 2015a ).…”

Watermelon is commonly affected by Fusarium wilt in a monoculture cropping system. Wheat intercropping alleviates the affection of Fusarium wilt of watermelon. The objective of this study was to determine the effects of wheat and watermelon intercropping on watermelon growth and Fusarium wilt. Our results showed that wheat and watermelon intercropping promoted growth, increased chlorophyll content, and photosynthesis of watermelon. Meanwhile, wheat and watermelon intercropping inhibited watermelon Fusarium wilt occurrence, decreased spore numbers, increased root vigor, increased antioxidant enzyme activities, and decreased malondialdehyde (MDA) content in watermelon roots. Additionally, wheat and watermelon intercropping enhanced the bacterial colonies and total microbes growth in soil, decreased fungi and Fusarium oxysporum f. sp. niveum (FON) colonies, and increased soil enzyme activities in watermelon rhizosphere soil. Our results indicated that wheat and watermelon intercropping enhanced watermelon growth and decreased the incidence of Fusarium wilt in watermelon. These effects could be due to intercropping inducing physiological changes, regulating soil enzyme activities, and/or modulating soil microbial communities.

“…Maize has received attention in intercropping systems with legumes, pepper, peanut, alfalfa and other crops because of its positive effect on crop yield and nutrient use efficiency ( Gao et al, 2021 ; Jiao et al, 2021 ; Zhang et al, 2021 ; Ben-chuan et al, 2022 ; Wu et al, 2022 ). Cassava, a widely grown crop in the tropics and subtropics, is relatively drought-tolerant and highly resilient to climate change and is regarded as an important crop for food security ( Enesi et al, 2022 ).…”

The maize/cassava relay intercropping system can be a specific and efficient cropping pattern in a tropical/subtropical field. Relay intercropping systems contribute to the optimization of land use, fostering sustainable and efficient agriculture. This study entails a first-year comparative intercropping experiment using maize (Zea mays L.) and cassava (Manihot esculenta Crantz). We determined the soil nutrient contents and physicochemical properties as well as the microbial communities by high-throughput sequencing. We found that the relay intercropping system changed the bacterial community structure, especially the rhizosphere microorganisms. The bacterial community was characterized by a higher abundance of the phyla Chloroflexi, Proteobacteria, and Actinobacteria and of the genus AD3, which are related to nutrient cycling and decreased bioavailability of Cd. At the same time, the relay intercropping system reduces the relative abundance of pathogenic bacteria and biomarkers of organic pollution. The relay intercropping systems significantly boosted soil pH and available K levels in addition to the monocropping yield. The results of this study suggest that maize/cassava relay intercropping, starting from the first year, not only provides a stable supply of food and income due to the diversified cropping systems but is also beneficial for the improvement of soil quality and the soil microbial community.
