“…An interaction between B and P for canola and potato has not been studied earlier to our knowledge, but our results corresponded well with studies where high P supply reduced tissue B concentrations in crops like maize and pea (Yamanouchi 1980, Salinas et al 1986, Chatterjee et al 1990, Günes and Alpaslan 2000. A recent study found a significant positive correlation between B uptake and P supply (most of the P applications are P sufficient) in barley (Mühlbachová et al 2017) but it was found that wheat shoot B concentration was not affected by low P availability. Some reports indicated that P deficiency enhanced the severity of B deficiency in sweet potato, radish and sunflower (Nusbaum 1947, Tanaka 1967.…”

A large proportion of global agricultural soils contain suboptimal available phosphorus (P) for the growth of many plant species. Boron (B) plays important roles in plant growth and development, but limited research has been conducted to study B uptake under low P availability. This study comprised a hydroponic and a mini-rhizobox experiment with canola (Brassica napus L.), potato (Solanum tuberosum L.) and wheat (Triticum aestivum L.) under P sufficient and deficient conditions. Boron concentrations, rhizosphere soil pH, and gene expression of BnBOR1 in canola were determined. Shoot B concentrations were found significantly increased (11–149%) by low P availability in potato and canola but not in wheat. Reverse transcription polymerase chain reaction (RT-PCR) indicated that BnBOR1;2a, BnBOR1;2c, and BnBOR1;3c were up-regulated after seven days of low P treatment in canola roots. Our results indicate that plant shoot B concentration was dramatically influenced by P availability, and dicots and monocots showed a contrasting B concentration response to low P availability.

“…The trial represents the second part of a three-year field experiment conducted in 2015-2017 at the Humpolec experimental station (Bohemian-Moravian Highlands, Czech Republic, 49.5546239N, 15.3485489E), altitude 525 m a.s.l. The first part of this field trial comprises the effects of increasing doses of phosphorus on boron availability and B-uptake (Mühlbachová et al 2018).…”

“…Boron availability depends on ionic strength, pH, soil biological cycle, humification in soils and also on the association with variety of soil constituents including organic matter content, type and the amount of minerals or formation of colloids; it is also present in adsorbed/exchange forms, occluded in mineral phases (clays and Fe/Al hydroxides) (Matula 2007b, Majidi et al 2010, Kot 2015, Mühlbachová et al 2018. Boron is available for plants as undissociated boric acid, which means that it is complexed in a variety of organic molecules in soil (Hu and Brown 1997).…”

The three-year field experiment (2015–2017) with graded doses of magnesium (Mg) and sulphur (S) was carried out at the Humpolec experimental station (49.5546239N, 15.3485489E; Czech Republic). The interactions between boron (B), Mg and S in the soil were studied. No boron was applied into soils. Contents of B, S and Mg in the soil were determined by the Mehlich 3 and NH4 acetate methods. The crop rotation was: spring barley-oilseed rape-winter wheat. Three Kieserite doses (S and Mg fertiliser) were applied. Sulphur treatments were 10-20-40 kg S/ha to cereals and 20-40-80 kg S/ha to oilseed rape. The doses of Mg were: 13-26-52 kg Mg/ha to cereals and 26-52-104 kg Mg/ha to oilseed rape. A significant gradual decrease of B-Mehlich 3 was observed under Kieserite treatments during the experiment (from 1.24 mg B/kg in control in the 1st year to 0.92 mg B/kg in the 3rd year). On the contrary, B-NH4 acetate contents in soils remained similar during 2015–2017 in control soils (0.33–0.39 mg B/kg) and significantly decreased under Kieserite treatments, namely by 55–57% in 2016 and by 43–48% in 2017. A significant decrease of B content in soils was noted since the second year of experiment after oilseed rape. The boron contents in soils were affected in several ways – by adsorption of B on magnesium oxides and other substances, exchange with SO42– anions and possible leaching, and also by the uptake by grown crops, mainly oilseed rape.

“…This result is in agreement with [16] who reported that B showed greater performance to leaf-stem, total dry matter weight of plant. Muhlbachova et al [17] have found positive correlation between dry matter yield and B contents in Barley. According to Han et al [18], B deficiency influence plant growth by reducing enzymatic activities and lowering stomatal conductance and CO2 assimilation in plant leaves.…”

To ensure both food and nutritional security of teeming millions of Bangladesh, cropping intensity must be increased along with nutritional food production. Mungbean, which is an important source of protein, can easily cope with the intensive cropping system due to short duration. But sometimes, to obtain maximum productivity per unit area in a calendar year, mungbean cannot be sown in optimum time. Considering this, a field study was carried out at Sher-e-Bangla Agricultural University to explore the effect of additional potassium and boron application to increase the yield of late sown mungbean which was sown on 25 October. The experiment was laid out in randomized complete block design with three replications and five treatments. Results revealed that additional potassium and boron along with recommended fertilizer dose had significant influence on growth, yield and yield contributing characters of late sown mungbean. The growth and yield of late sown mungbean is hampered due to temperature stress which cannot be overcome by recommended dose only but can be by addition of extra potassium and boron with recommended dose. The highest seed yield (1.12 t ha-1) was obtained from recommended dose along with 10 Kg K and 2 Kg B ha-1 which was 40% higher than recommended dose only. Similar results were recorded for other parameters also. So, supplementation of recommended dose with 10 Kg K and 2 Kg B may be suggested to increase growth and yield of late sown mungbean.
