“…In an intercropping system, the competition for nutrients among the crop species can be reduced by selecting appropriate crops with dissimilarity in nutrient needs, root morphology and time of peak requirements. Furthermore, use rhizobia inoculants in addition to the recommended fertilizer inputs applied in intercropping systems may boost the availability of nutrients to crops and thus enhance the productivity of the intercropping system [140]. In maize + pea intercropping system when crops were fertilized with low N with a higher density of maize, there was more corn yield in the oasis region of northwest China [141].…”

Intercropping—A Low Input Agricultural Strategy for Food and Environmental Security

Intensive agriculture is based on the use of high-energy inputs and quality planting materials with assured irrigation, but it has failed to assure agricultural sustainability because of creation of ecological imbalance and degradation of natural resources. On the other hand, intercropping systems, also known as mixed cropping or polyculture, a traditional farming practice with diversified crop cultivation, uses comparatively low inputs and improves the quality of the agro-ecosystem. Intensification of crops can be done spatially and temporally by the adoption of the intercropping system targeting future need. Intercropping ensures multiple benefits like enhancement of yield, environmental security, production sustainability and greater ecosystem services. In intercropping, two or more crop species are grown concurrently as they coexist for a significant part of the crop cycle and interact among themselves and agro-ecosystems. Legumes as component crops in the intercropping system play versatile roles like biological N fixation and soil quality improvement, additional yield output including protein yield, and creation of functional diversity. But growing two or more crops together requires additional care and management for the creation of less competition among the crop species and efficient utilization of natural resources. Research evidence showed beneficial impacts of a properly managed intercropping system in terms of resource utilization and combined yield of crops grown with low-input use. The review highlights the principles and management of an intercropping system and its benefits and usefulness as a low-input agriculture for food and environmental security.

“…Appropriate intercropping can increase crop yield, and its great achievements in agricultural production are well-known (Nyoki and Ndakidemi, 2016 ). In particular, the intercropping of soybean and grasses (sugarcane) is also recognized and widely used globally (Solanki et al, 2019 ).…”

Effect of Two Different Sugarcane Cultivars on Rhizosphere Bacterial Communities of Sugarcane and Soybean Upon Intercropping

Intercropping of soybean and sugarcane is an important strategy to promote sustainable development of the sugarcane industry. In fact, our understanding of the interaction between the rhizosphere and bacterial communities in the intercropping system is still evolving; particularly, the influence of different sugarcane varieties on rhizosphere bacterial communities in the intercropping process with soybean, still needs further research. Here, we evaluated the response of sugarcane varieties ZZ1 and ZZ9 to the root bacterial community during intercropping with soybean. We found that when ZZ9 was intercropped with soybean, the bacterial diversity increased significantly as compared to that when ZZ1 was used. ZZ9 played a major role in changing the bacterial environment of the root system by affecting the diversity of rhizosphere bacteria, forming a rhizosphere environment more conducive to the growth of sugarcane. In addition, our study found that ZZ1 and ZZ9 had differed significantly in their utilization of nutrients. For example, nutrients were affected by different functional genes in processes such as denitrification, P-uptake and transport, inorganic P-solubilization, and organic P-mineralization. These results are significant in terms of providing guidance to the sugarcane industry, particularly for the intercropping of sugarcane and soybean in Guangxi, China.

“…Bekere et al (2013) report that the effectiveness of seed inoculation on acidic soils can be increased by means of lime fertilization. Nyoki and Ndakidemi (2016), in turn, showed a beneficial effect of soybean seed inoculation along with fertilization with phosphorus and potassium. In a study by Rampim et al (2015), no increase in soybean seed yield was obtained under the influence of seed inoculation with symbiotic bacteria.…”

A field experiment was carried out with three bacterial inoculants: HiStick® Soy, Nitragina, Nitrazon and the control. Number and dry weight of nodules were significantly higher with inoculation of bacterial inoculants compared to the control. In 2017, the most pods per plant were obtained after the use of Nitrazon or HiStick® Soy, while in 2018, after the use of HiStick® Soy or Nitragina. In 2018, the highest 1000 seed weight was obtained after the use of Nitragina. In 2017, the seed yield was the most favourably affected by the inoculants HiStick®Soy (3.31 t ha -1 ) and Nitrazon (3.37 t ha -1 ) and in 2018, by HiStick® Soy (3.92 t ha -1 ) and Nitragina (3.87 t ha -1 ). High Soil Plant Analysis Development (SPAD) and Leaf Area Index (LAI) readings, were observed with HiStick® Soy.
