“…The COVID-19 pandemic is a hardchallenging test to the worldwide economy and international trade, for instance production and consumption are surmounted back all over the world (WORLD TRADE ORGANIZATION 2020). The N, P and K elements are the most important nutrients for plant growth and productivity (SELEIMAN 2014;KWON et al 2019). The world production of nitrogen (N), phosphate (P 2 O 5 ) and potassium (K 2 O) fertilizers were 122.7, 50.8 and 40.4 Mt, while the agricultural uses of those fertilizers were 110.2, 48.6 and 38.7 Mt during 2016, respectively (Figure 2).…”

The whole world is in a great danger due to the novel coronavirus (COVID-19) pandemic. In December 2019, the outbreak of COVID-19 took place in Wuhan, China and then rapidly spread all over the world. The current study provides potential expectations for the adverse impact of (COVID-19). The global infection affected globe on agricultural level such as agriculture, food supplies and animal production sectors. Till today, 29th April 2020, there is no vaccine available for treating novel coronavirus, consequently, the outbreak resulted in closing borders and reducing production following social distancing measures. This short communication illustrates the possible implications and expected outcomes of the outbreak of coronavirus (COVID-19) on agricultural, food security, integrated pest management (IPM), animal productivity; and it predicts, as well, the possible adverse impacts on the economy worldwide. Brazil has one of the most important tropical agriculture in the world, being a leader in soybean production in the world. This chain impacts others such as meat and eggs. The impact of COVID-19 will be positive, encouraging the country to consolidate its leadership in the world market, stimulating exports, the machinery, inputs and fertilizers market, as well as generating employment and income in the country.

“…The effect of coronavirus pandemic on fertilizer application and soil fertility is shown in Figure 3. Nitrogen (N), Phosphorus (P), and Potassium (K) are the primary essential nutrients required by plants in large quantities for growth and productivity (Kwon et al, 2019). As shown in Figure 4, the world production of fertilizers containing nitrogen (N), phosphate (P 2 O 5 ), and potassium (K 2 O) amounted to 122.7, 50.8, and 40.4 Mt, respectively, while in 2016, the agricultural uses of these fertilizers were 110.2, 48.6 and 38.7 Mt sequentially.…”

The unexpected outbreak of novel COVID-19 in late 2019 and continual spread across the world has disrupted the agricultural value chain. The World Health Organization (WHO) prescribed border closure, lockdown, social distancing, wearing a mask, and handwashing to combat the pandemic. These control measures, especially the closure of borders, have affected the importation and supply of fertilizer for crop production. The current study presents potential expectations for the adverse effects of coronavirus pandemic on fertilizer supply and application, soil fertility, and crop yield. The study indicates that the effect of the COVID-19 pandemic has made the delivery of fertilizers to farmers very difficult. Hence, the application of fertilizer on time by farmers was problematic. It was also discovered that the COVID-19 control measure enforced can delay crop planting on time and the use of optimum quality and quantity of fertilizer. Therefore, crop yield will be affected and the quantity of crop produced will be reduced.

“…Root system architecture (RSA) is the general spatial arrangement of individual parts of the root system and enables the plant to acquire adequate resources from the soil. The rate at which individual parts of the root system develop and grow can be reformed by their response to environmental signals, including changes in water, nutrient, and oxygen availability, or pathogens and pests [2,3].…”

Nitrate (NO 3 -) and auxin are key regulators of root growth and development, modulating the signalling cascades in auxin-induced lateral root formation. Auxin biosynthesis, transport, and transduction are significantly altered by nitrate. A decrease in nitrate (NO 3 -) supply tends to promote auxin translocation from shoots to roots and vice-versa. This nitrate mediated auxin biosynthesis regulating lateral roots growth is induced by the nitrate transporters and its downstream transcription factors. Most nitrate responsive genes (short-term and long-term) are involved in signalling overlap between nitrate and auxin, thereby inducing lateral roots initiation, emergence, and development. Moreover, in the auxin signalling pathway, the varying nitrate supply regulates lateral roots development by modulating the auxin accumulation in the roots. Here, we focus on the roles of nitrate responsive genes in mediating auxin biosynthesis in Arabidopsis root, and the mechanism involved in the transport of auxin at different nitrate levels. In addition, this review also provides an insight into the significance of nitrate responsive regulatory module and their downstream transcription factors in root system architecture in the model plant Arabidopsis thaliana.grow well when taking N only from NH 4 + [4]. This uptake system of N by the roots is under the synchronized control of nutrients availability and hormonal signalling [2,3]. Nitrate (NO 3 − ) plays a signal regulatory role in many physiological processes including root growth. The nutrient uptake efficiency depends on root system architecture in the soil [9], and these processes are controlled by several gene-transcript levels, which are regulated by NO 3 − [10].NO 3 regulates root branches under various signalling pathways, such as NRT1.1 (dual-affinity NO 3 − responsive gene), which is assumed to participate in the nitrate-sensing system [11,12], and also governed by auxin [13].Signalling communication is a general rule rather than an omission. For instance, it is cited that about 1545 genes were the nutrient-related signals of NO 3 − , NH 4 + , or both nitrogen forms. Also, 982 (64%) genes were controlled by hormonal signals [14]. Several studies reveal that hormone biosynthesis, transport, and transduction are significantly influenced by several mineral nutrients [11].Hormones play a key role in the root-growth adaptation to NO 3 − readiness [13]. Numerous studies have also shown that NO 3 − regulation of root system architecture (RSA) entails an overlap between NO 3 − and auxin signalling pathways [13,15]. IAA is the most researched and best naturally occurring active auxin [12], and it plays a specific role in the control of systemic inhibition of fresh lateral roots (LRs) developments in response to the sufficient supply of nitrate [16]. Both external NO 3 − and IAA supply significantly influence the auxin concentration in the tiller nodes [17]. As part of the root system, lateral root not only depends on the external NO 3 − supply, but also on the amount of inter...
