“…This decrease is because of the significant increase in boron concentration and non-significant increase in potassium concentration of the leaves. These results are similar to the findings of Tariq et al [19], who stated that as the boron concentration in tobacco leaf increases the K/B ratio considerably decreases. Similarly, decreasing trend for K/B ratio in other crops due to boron was also reported for cauliflower [35], radish [15] and tomato [36].…”

“…This positive effect of boron on potassium in tobacco is a good indicator for good quality tobacco, because potassium enhances the smoking and ashing quality by increasing the burning quality of tobacco. These findings are in conformation with the early work of [19] [34]. …”

“…The decreasing trend in Cl/B ratio is a good indicator for tobacco because the Cl decreases the burning quality of tobacco and also affects the grade index. Similar results were observed for tobacco [19], hot pepper [37] and tomato crops [38].…”

“…The chemical composition of tobacco leaf plays a key role in the evaluation of tobacco quality. The absolute and relative amount of these constituents not only depends on crop varieties and maturity, soil, climatic condition and curing process, but also depends on the responsive mineral nutrition of tobacco crop, such as boron [18] [19]. Boron is one of the major deficient micronutrients after zinc in Pakistan [20], and B not only affects the yield but also affects the marketing value of tobacco leaf.…”

The present study was based on the general hypothesis that boron may affect the accumulation and utilization of other nutrients in plant. For this purpose a field experiment was carried out to find out the influence of boron on the different nutrients content in FCV tobacco (Nicotiana tabacum L.) at TRS Khan Garhi, Mardan, during 2010-2011. Two varieties TM-2008 and Speight G-28 were tested and six levels of boron (0, 0.5, 1, 2, 3 and 5 kg•ha −1 ) were applied in the form of boric acid, in randomized complete block design in split plot arrangement and replicated thrice. Results indicated that the yield of tobacco crop increased with 1 kg•B•ha −1 and then decreased sequence wise in both varieties. N and P concentrations were significantly affected by applied boron. Similarly, potassium was increased which is a good indication for a better quality of tobacco crop. Application of boron significantly increased the concentrations of boron nutrients ratios such as K/B; Cl/B and Mn/Fe were decreased while K/Cl and Zn/Cu ratios were increased at lower boron concentrations but decreased at higher concentrations of boron. The fertilizer use efficiency of both the cultivars showed similar trend; however, Speight G-28 was more efficient than TM-2008 in boron accumulation. The overall results revealed that the application of boron should be encouraged for balancing nutrients concentration, thus getting higher yield in the prevailing conditions.

“…Results also reveal that the reduction of K in all cultivars differed with the level of B. The system regarding K-B synergism is based on enhanced K uptake with the increasing B levels that caused Ca concentration depression because of the antagonistic effect [Lopez-Lefebre et al 2002, Tariq and Mott 2006, Ahmed et al 2008, Tariq et al 2010. Our results are contradictory to above mentioned reports about the role of toxic B in K uptake and accumulation.…”

Excess of boron in soil and irrigation water is a serious constrain to crop production in many areas of the World as well as in Turkey. A pot experiment was carried out with to screen safflower cultivars in order to investigate the effects of boron toxicity stress on early growth and ions composition. Three safflower cultivars (Carthamus tinctorius cv. Balci, Yenice, Remzi Bey) were grown in pots containing alkaline and potassium rich soil, additionally supplemented with 0, 4, 8, 16, 32, 64 and 128 mg kg -1 boron. Chlorophyll content of all cultivars decreased with excessive boron levels. Plant height, shoot fresh and dry weight significantly increased at 4 mg kg -1 boron level followed by sharp decline with the other treatments. Boron content of cultivars increased and the highest amount was observed at 128 mg kg -1 boron level. Sodium content of all cultivars gradually increased with increase in B concentration. Whereas, potassium and calcium content reduced with increased B. Phosphorus content of all cultivars were least at 128 mg kg boron level. Results revealed that cv. balci appeared to tolerant to boron in soil up to 32 mg kg -1 and can be recommended for growing and breeding material for boron rich soils of Central Anatolia.
