“…It plays a role in membrane metabolism and function, thereby being involved in enzyme reactions, as well as the transport of ions, metabolites, and hormones [2,[37][38][39]. The element stimulates, inhibits, or stabilize enzymes; it is involved in the transport of sugars across the membrane, lignin and flavonoid synthesis, and metabolism of auxins, nitrogen compounds, and phenols [32,[40][41][42][43][44].…”

Boron is an essential plant micronutrient taken up via the roots mostly in the form of boric acid. Its important role in plant metabolism involves the stabilization of molecules with cis-diol groups. The element is involved in the cell wall and membrane structure and functioning; therefore, it participates in numerous ion, metabolite, and hormone transport reactions. Boron has an extremely narrow range between deficiency and toxicity, and inadequate boron supply exhibits a detrimental effect on the yield of agricultural plants. The deficiency problem can be solved by fertilization, whereas soil boron toxicity can be ameliorated using various procedures; however, these approaches are costly and time-consuming, and they often show temporary effects. Plant species, as well as the genotypes within the species, dramatically differ in terms of boron requirements; thus, the available soil boron which is deficient for one crop may exhibit toxic effects on another. The widely documented intraspecies genetic variability regarding boron utilization efficiency and toxicity tolerance, together with the knowledge of the physiology and genetics of boron, should result in the development of efficient and tolerant varieties that may represent a long-term sustainable solution for the problem of inadequate or excess boron supply.

“…This response was partially compensated by the systematic change seen in the hydrophobic and structural metabolite fraction. It has been noted that under boron deficiency, levels of phenolic metabolites can become elevated in leaves [ 99 ]. Though we did not attempt to analyze specific metabolites within this fraction, we expect that such compounds can contribute heavily to the hydrophobic constituents that make up lignin.…”

In agriculture, boron is known to play a critical role in healthy plant growth. To dissect the role of boron in maize metabolism, radioactive carbon-11 (t½ 20.4 min) was used to examine the physiological and metabolic responses of 3-week-old B73 maize plants to different levels of boron spanning 0 mM, 0.05 mM, and 0.5 mM boric acid (BA) treatments. Growth behavior, of both shoots and roots, was recorded and correlated to plant physiological responses. 11CO2 fixation, leaf export of [11C]-photosynthates, and their rate of transport increased systematically with increasing BA concentrations, while the fraction of [11C]-photosynthates delivered to the roots under 0 mM and 0.5 mM BA treatments was lower than under 0.05 mM BA treatment, likely due to changes in root growth. Additionally, solid-phase extraction coupled with gamma counting, radio-fluorescence thin layer chromatography, and radio-fluorescence high-performance liquid chromatography techniques applied to tissue extracts provided insight into the effects of BA treatment on ‘new’ carbon (as 11C) metabolism. Most notable was the strong influence reducing boron levels had on raising 11C partitioning into glutamine, aspartic acid, and asparagine. Altogether, the growth of maize under different regimes of boron affected 11CO2 fixation, its metabolism and allocation belowground, and altered root growth. Finally, inductively coupled plasma mass spectrometry provided insight into the effects of BA treatment on plant uptake of other essential nutrients. Here, levels of boron and zinc systematically increased in foliar tissues with increasing BA concentration. However, levels of magnesium, potassium, calcium, manganese, and iron remained unaffected by treatment. The rise in foliar zinc levels with increased BA concentration may contribute to improved 11CO2 fixation under these conditions.

“…Sahrawat et al (2008) attributed reduced concentration of Zn with P fertiliser application to several mechanisms including dilution effects on the concentration of Zn in plants. In wheat, Seth and Aery (2017) reported that B concentration decreased significantly at higher P levels than lower P levels. Studies by Brdar-Jokanovi (2020) and Kaya et al (2009) also reported that high P content could reduce B content in leaves, while Blackwell et al (2019) demonstrated that increasing P supply led to the decrease in B concentration in plant tissues, as found in our present study.…”

We conducted on-farm trials in the southern Guinea Savanna of Ghana in 2016 and 2017 to evaluate soyabean response to three fertiliser blends to guide farmers towards profitable adoption of appropriate phosphorus (P) fertiliser blend for improved soyabean production. Old YARA Legume (OYL), New YARA Legume (NYL) and Triple Superphosphate (TSP) fertiliser blends were evaluated. In both years, the P fertiliser blends were evaluated in a Randomised Complete Block Design with 20, 30, and 40 kg P ha -1 application rates together with control. P fertiliser application increased soyabean yields by 1070 kg ha -1 . In 2016, fertiliser blend use efficiency (BUE) ranged from 2.9 kg grain per kg fertiliser blend applied with the NYL applied at 40 kg P ha -1 to 7.4 kg grain per kg fertiliser blend applied with the TSP applied at 40 kg P ha -1 with significant differences between treatments. In 2017, BUE ranged from 2.5 kg grain per kg fertiliser blend applied with OYL applied at 40 kg P ha -1 to 9.2 kg grain per kg fertiliser blend applied with the TSP applied at 40 kg P ha -1 with significant differences between treatments. However, P use efficiency did not significantly differ between the different treatments both in the 2016 and 2017 trials. In both 2016 and 2017 trials, the highest benefit cost ratio was attained at the lowest application rate for all the three fertiliser blends suggesting the need to review the current application rate of 30 kg P fertiliser ha -1 promoted in northern Ghana. Furthermore, the provision of credit and/or subsidy for farmers by the government is required to enable uptake and utilisation of fertilisers by farmers.
