Micronutrients or trace elements are fundamentally just as important as macronutrients for plants to thrive, yield, and produce higher-quality products. B, Cu, Fe, Zn, Mn, Mo, Cl and Ni are the essential micronutrients required by all types of crops in varying amounts. The micronutrient requirements of the plants are satisfied by the soil, chemical fertilizers and other sources. These mineral micronutrients play vital roles in various crops such as photosynthesis, respiration, chlorophyll synthesis, increased sugar content and TSS in fruits, increased pollen viability, symbiotic N-fixation, production of vitamins etc. Lack of micronutrient fertilizers causes plants to absorb trace elements insufficiently, which results in significant losses in yield and quality of various crops. Crop quality is significantly impacted by the synergistic and antagonistic interactions between various nutrients. Therefore, it's crucial to ensure optimal absorption of soil micronutrients. Consequently, it is acknowledged that a balanced nutrition is of utmost significance. Morphological, organoleptic, and nutritional qualities are essential for the value addition of harvested goods. The various crop quality parameters that are improved by applying micronutrients are aroma in rice, protein content in wheat and pulses, oil content in oilseed, curd\head size in cole crops, TSS and ascorbic acid content in fruits, etc. Enhancing crop quality still remains a major challenge in this era of increasing food demand, especially in the developing world. The objective of this article is to gain deeper insights into new advancements in the research of micronutrients contributing to the quality of various crops to ensure consumer preferences and nutritional attributes.

“…• Seventh, there is a great variation in yield and tolerance to biotic and abiotic stressors across genotypes and under different climate conditions (Pfeiffer et al, 2019). • Finally, there are multiple biotic (e.g., pests, diseases, birds, and parasitic weeds) and abiotic (e.g., heat stress, soil moisture deficit, and waterlogging) that affect the health of the sorghum plant, and, in turn, might reduce its productivity (Perumal et al, 2018;Abreha et al, 2021;Fakrudin et al, 2021) or even result in crop failure in extreme cases.…”

Some cereal crops can withstand harsh growing conditions, and, hence, can be considered an important line of defense against food shortage under climate change. Sorghum (Sorghum bicolor (L.) Monech) is the main food crop for millions of people, especially in sub-Saharan Africa and South Asia. This crop performs well under input constraints (e.g., limited water) and exhibits high resilience to adverse climate conditions (e.g., high temperature, drought, and waterlogging), making it a star crop for combating hunger under climate change. However, sorghum and other similar crops are not tolerant in absolute terms. Climate change could push the growing conditions of these crops beyond the limits they can tolerate, jeopardizing the food security of millions of people around the world. In this research, we analyzed the current status of sorghum production, trends, and factors controlling sorghum yield using empirical approaches. Especially in sub-Saharan Africa, this crop is cultivated widely under unfavorable climate conditions and sub-optimal input levels. Our findings raise multiple concerns as well as highlight opportunities for the sustainability of sorghum cultivation in a future with climate change. Sorghum yield seems to increase persistently despite global warming due to an improved inputs approach, offering hope that similar adaptation approaches can be fruitful, especially in sub-Saharan Africa. A combination of interventions including adequate use of fertilizers and technology adoption (e.g., tolerant cultivars), efficient management (e.g. improved irrigation), and better agronomic practices, is the key to boosting sorghum yield and ensuring the sustainability of this important crop under a warmer climate.

“…Sorghum, like other cereal crops, is susceptible to biotic stresses such as bacterial, fungal, nematode, and virus infections. The most common diseases are fungal infections caused by smut, charcoal rot, ergot, downy mildew, blast, and rust, which have a greater impact on sorghum plant health and productivity (Fakrudin et al, 2021). Other common fungal diseases that affect sorghum fodder and grain production include blast (Pyricularia oryzae) and rust (Puccinia purpurea).…”

Recent advancements in the breeding of sorghum crop: current status and future strategies for marker-assisted breeding

Sorghum is emerging as a model crop for functional genetics and genomics of tropical grasses with abundant uses, including food, feed, and fuel, among others. It is currently the fifth most significant primary cereal crop. Crops are subjected to various biotic and abiotic stresses, which negatively impact on agricultural production. Developing high-yielding, disease-resistant, and climate-resilient cultivars can be achieved through marker-assisted breeding. Such selection has considerably reduced the time to market new crop varieties adapted to challenging conditions. In the recent years, extensive knowledge was gained about genetic markers. We are providing an overview of current advances in sorghum breeding initiatives, with a special focus on early breeders who may not be familiar with DNA markers. Advancements in molecular plant breeding, genetics, genomics selection, and genome editing have contributed to a thorough understanding of DNA markers, provided various proofs of the genetic variety accessible in crop plants, and have substantially enhanced plant breeding technologies. Marker-assisted selection has accelerated and precised the plant breeding process, empowering plant breeders all around the world.
