Enhancing potato growth and yield attributes via both Boron (Br) and Selenium (Se) is a great potential nowadays. Therefore, the present investigation was done to study the effe ct of Boron and Selenium singly or in combination as foliar application on plant growth, yield and quality of two potato cultivars 'Lady Rosetta and Caruso' during both seasons of 2016/2017 and 2017/2018. The experimental layout was split plots system in a randomized complete blocks design with three replications. Cultivars were arranged as the main plots and concentrations of Boron and Selenium singly or in combination were assigned as sub-plots. Boron was sprayed in three concentrations 0, 50, and 100 mg/l whereas Selenium was used at 0, 5, and 10 mg/l concentrations twice at 55 and 70 days after planting. The study indicated that plant growth and yield of potato plants were significantly enhanced by Boron and Selenium treatments. Plant height, tuber dry weight, number of tubers/plant, tuber yield/plant, tuber yield/feddan, tuber TSS %, ascorbic acid, tubers sugars (i.e. starch, reducing, non-reducing and total sugars), leaf total chlorophyll, leaf and tubers contents of N, P, K, Br and Se of both potato cultivars ' Lady Rosetta and Caruso' were significantly enhanced by Boron (100 mg/l) combined with Selenium (5 mg/l) foliar application at 55 and 70 days after planting during both seasons of the study.

“…However, there have been reports of beneficial effects at low Se doses on plant growth (Hartikainen, 2005;Lyons et al, 2009;PilonSmits et al, 2009;Rios et al, 2009;Yao et al, 2009;Malik et al, 2011). In the kenaf plants, the slight increase in dry biomass for the lowest doses was not statistically significant.…”

Due to selenium (Se) deficiency, Se fortification of food and feed is applied in many countries. Therefore, potential use of Se-enriched kenaf was investigated based on its Se accumulation, its potential to transform accumulated Se to other Se species, and effect of Se accumulation on its growth. Kenaf was grown with different levels of two Se fertilizers (selenite and selenate) at concentrations ranging from 0 to 4 mg Se (kg soil) -1 . Total Se concentrations in the plants grown on selenate-treated soil amounted to (1019 ± 136) mg Se (kg dry weight) -1 and were much higher compared to plants grown on selenite-treated soil. Identified Se species were selenite, selenate, Se-methionine, and Se-cystine. Biomass yield, net photosynthesis, and chlorophyll index of the plants decreased when plants were grown on soils treated with high doses of selenate.

“…Increases in sucrose and total sugar concentration up to the 400 and 800 g ha −1 treatments may be due to the activity of carbohydrate metabolism enzymes. Malik et al (2011) observed that mung bean (Phaseolus aureus Roxb.) exposed to Se showed increased activity of amylases and invertases.…”

Selenium (Se) is considered a beneficial element for plants; however, in high concentrations, it causes negative effects on plant physiology and development. This study reports the first physiological, nutritional, and ultrastructural description of Se toxicity in cowpea growing under field conditions. Selenium was supplied as a foliar application of sodium selenite at varying concentrations (0, 50, 100, 200, 400, 800, 1200, and 1600 g ha −1). An increased yield was observed with the application of 50 g ha −1 Se. Application of concentrations higher than 50 g ha −1 caused leaf toxicity. Increased lipid peroxidation and hydrogen peroxide concentration and reduced total sugars, sucrose, and carotenoid concentration were observed at highest doses tested (1200 and 1600 g ha −1). Applications of more than 50 g ha −1 Se reduced the phloem diameter, caused chlorosis of the leaf blade with a coalescence of lesions, and caused pink salt deposits to appear. Lesions were observed mainly near the trichomes on the adaxial surface of the leaf blade. An analysis of the element distribution with microprobe Xray fluorescence spectrometry (μ-XRF) revealed accumulation of Se, calcium (Ca), potassium (K), copper (Cu), and manganese (Mn) near the primary vein and in the necrotic brown areas of the leaf lesions. In contrast, Na was homogeneously distributed in the leaf tissue.
