The HOMO–LUMO gap of the nanocage does not change significantly upon urea adsorption, while the Fermi level is dramatically changed from −4.27 eV in the pristine nanocage to upper energies upon urea adsorption. The geometric structure, adsorption energy, solvation effect, charge transfer, and frequency analyses of the urea adsorption on the nanocage models showed that the urea molecule could be firmly adsorbed by the nanocage and the nanocage could be a potential efficient adsorbent for the adsorption of urea.

Post transcriptional gene regulation in wheat cultivars caused by boron (B) toxicity has not been reported to date. In this study, two wheat cultivars Bolal-2973 (B-tolerant) and Atay-85 (B-sensitive) were compared with regard to the transcriptional regulation of miR319, miR172 and miR398 and their plausible target genes in order to address differences in their performances under high B levels. The expression levels of Cu/ZnSOD gene were found to be greater in Atay exposed to toxic B compared to Bolal, as verified by stable expression level of miR398.

Earlier our colleagues detected that the genes related to jasmonate (JA), ethylene, and cell wall modification were significantly regulated under boron (B) toxicity in wheat. Determination of regulation mechanisms of these novel genes under B toxicity is very important in Arabidopsis thaliana as a model plant. As key regulators, the microRNAs (miRNAs) regulate gene expression at the posttranscriptional level and respond to numerous abiotic stresses in plants.

The fine-tuned regulation of the Halliwell–Asada cycle (ascorbate–glutathione pathway) in Arabidopsis thaliana under boron (B) toxicity was shown in our previous report. In this study, we investigated the expression levels of some members of the glutathione S-transferase (GST) superfamily, such as phi (GSTF2, GSTF6, GSTF7, and GSTF8), tau (GSTU19), and zeta (GSTZ1) classes in Arabidopsis thaliana that were exposed to 1 mM boric acid (1B) and 3 mM boric acid (3B).

Recently, boron (B) has been found to form a complex with anthocyanin, which could be evidence for the B tolerance mechanisms that reduce free B in the leaf tissues of plants. However, the molecular mechanism of anthocyanin biosynthesis and transport has not been satisfactorily elucidated in plants exposed to toxic B. Therefore, the changes in expression levels of some of the phenylpropanoid pathway genes, early and late flavonoid biosynthetic genes, and transcription factors related to anthocyanin biosynthesis and transport were determined in Arabidopsis thaliana under B toxicity.

A pot experiment was conducted during kharif season of 2016-17 and 2017-18 in completely randomized design with two lime levels (0 and ¼ lime of LR), four phosphorus levels (0, 13.4, 26.8 and 40.2 mg P2O5 kg-1 ) and three boron levels (0, 0.45 and 0.90 mg B kg-1 ) to study the treatment effect on nutrient content and uptake of maize and soil properties. It was observed that lime had a significant effect on biomass yield, nutrient content and uptake of maize.

Boron is concerned with the precipitation of excess cation, buffer action, maintenance of conducting tissues and help in absorption of nitrogen. Its primary role is concerned with metabolism both with its uptake and efficient use in plants. Boron also affect the cambial and phloem tissues of storage root or stem apical meristems and leaves, vascular cambia of fruits and other organs which are capable of meristematic activities (Singh, 1991).

This behaviour may the related to restricted release of boron from organic complexes which ultimately impaired ability of plants to extract B from soil due to lack of moisture in the rhi7osphere. Even of B levels in soil is high, then also low soil moisture impairs transport of B to absorbing root surfaces (Das et al., 2016).

After nitrogen, phosphorus and potassium, sulphur is the fourth nutrient, whose deficiency is widespread in India. Sulphur deficiency is observed primarily due to high crop yield and therefore higher rate of sulphur removal by crops, and lesser use of sulphur-containing fertilizers. Boron foliar sprays seemed to overcome the deleterious effects of drought by overcoming the drought-related molecular responses and consequently appeared to meliorate sunflower growth under insufficient water conditions.

Field studies were conducted on application of zinc and boron to summer rice crop on Alfisols at Naganahalli village, Mysore district, Karnataka. The results showed that external application of zinc as ZnSO4 @ 20 kg ha-1 and boron as borax @ 4 kg ha-1 significantly enhanced the plant height number of tillers hill-1 , grains per panicle, thousand grain weight, grain yield and straw yield of paddy. Further there was significant increase in major (N, P and K), secondary (S, Ca and Mg) and micronutrient (Zn, Cu, Fe, Mn and B) status of soils.

An examination of the first-row-transition-metal-doped boron clusters, B14M (M = Sc, Ti, V, Cr, Mn, Fe, Co, Ni, and Cu) in the neutral state, is carried out using DFT quantum chemical calculations. The lowest-energy equilibrium structures of the clusters considered are identified at the TPSSh/ 6- 311+G(d) level. The structural patterns of doped species evolve from exohedrally capped quasi-planar structure B14 to endohedrally doped double-ring tubular when M is from Sc to Cu.

An experiment was conducted in 12 year old planted guava (Psidium guajava L.) garden at Kanpur (Uttar Pradesh) during the year 2014-15. The treatments comprised nine combinations of three ZnSO4 levels (0.50, 0.75, 1.00% solution) and three borax levels (0.2, 0.4, 0.6% solution) and one control of water spray. These 10 treatments were tested in factorial R.B.D. on guava.

The various factors responsible for maximizing the yield of greengram, phosphorus levels and frequency of boron levels is most important. It is necessary to use them economically in combination with phosphorus and boron, as greengram shows high response to high phosphorus levels and frequency of boron levels.
