Large-scale farming operations are win-win for grain production, soil carbon storage and mitigation of greenhouse gases

Sorghum (Sorghum bicolor (L.) Moench) is one of the most resilient crops grown in the tropical, subtropical, or temperate regions of Africa, Asia, Oceania, and Americas. Globally, the top five worldwide sorghum producers are USA, Nigeria, Sudan, Ethiopia, and India. Sorghum production area is declining and shifting to lower productivity regions or soil types; however, annual productivity gains continue in excess of 8.7 kg/ha due to genetics alone and up to 50 kg/ha when genetics and management combinations are considered. Growers prefer sorghum because of the low risk and reliable production especially in low-input production systems but often switch to cotton, maize, or soybean crops rather than intensify sorghum production. Further management (agronomic practices) and breeding efforts should be dedicated to increasing attainable yield and reduce the yield gap (potential minus actual yields). The latter can be achieved by improving the understanding of the complexity of the genotype (G) by environment (E) by management (M) interaction (G × E × M). A summary presenting best management (e.g., planting date, seeding depth, cultivar-/hybrid-type selection, row spacing, plant density, and crop rotations) of modern sorghum hybrid traits across environments could provide insights for yield improvement. This chapter provides an update on the state of the art on the sorghum management systems and production technology under diverse environments across the globe. We identify that sowing date and maturity group remain the most important management and genetic trait combinations for sorghum systems due to changes in production technologies, climate, and increased production in marginal areas of different continents.

Sorghum management systems and production technology around the globe

Crop developmental process and in turn its growth
phases (vegetative and reproductive) are influenced by
environmental factors, i.e. temperature and photoperiod
in field crops like sorghum. Crop growth and
biomass production is a function of genotype by environment
interaction, which is optimized through
management strategies. Crop grain yield is determined
as a product of its yield components like the
grain numbers per plant and the average kernel
weight at maturity. Grain numbers set at the panicle
initiation phase can be enhanced by best matching the
supply of nitrogen with its demand in the crop. Grain
growth dynamics, a function of genotype by environment
by management interaction is an important feature
that enhances sorghum productivity.
Rabi sorghum growing environment presents a challenge
through a receding soil moisture front which
decreases its response to applied external inputs like
nitrogen (N) fertilizer. Deep placement of top dressed
nitrogen fertilizer treatments increased rabi sorghum
grain yield by about 630–930 kg ha–1 over farmers,
practice of no fertilizer application. A management
strategy helped enhance the agronomic nitrogen use
efficiency to 16 kg grain per kg applied N, and the
rain water use efficiency to 15 kg ha–1 mm. Thus, the
hypothesis of increased rabi sorghum productivity per
rain drop through improved management intervention
in vertisols was validated.
