Sunflower (Helianthus annuus) is one of the most important oilseed plants known for its high
oil quality and content. Sunflower is among the plants with a high need for boron (B) Souza et
al. 2004). In order to meet the B requirements of plants; disodium octaborate tetrahydrate
(Etidot-67, Na2B8O13.4H2O; 20.8% B), borax (Na2B4O7.10H2O; 11% B), sodium tetraborate
(Na2B4O2.5H2O; 14% B), boric acid (H3BO3; 17% B), ulexite (NaCaB5O9. 8H2O, 13.3% B)
and colemanite (Ca2B6O11.5H2O; 15.8% B) are commonly used (Güneş et al. 2017). The
increase in soil and environmental pollution due to the intensive use of fertilizers and the
gradual depletion of raw material resources used in fertilizer production make more effective
use of fertilizers necessary in terms of sustainability. Next-generation smart fertilizers such as
nano-fertilizers may have the potential to serve this purpose. The efficiency of fertilizer use
can be increased by the use of nanotechnology for agricultural purposes and the development
of controlled release fertilizers and their use. Since nano-molecules are smaller than 100 nm,
their uptake and transport by plants may be superior to the bulk form of these molecules.
Thus, the effect of that nutrient can be increased by consuming less nutrient. Less fertilizer
consumption, on the other hand, can be effective in preventing environmental pollution
caused by fertilizers and in terms of efficient use of resources (Taskin and Gunes 2022). In
this study, it was aimed to compare the efficiency of nano-calcium borate in B uptake and
transport in sunflower plant with different boron fertilizers such as colemanite and Etidot-67
which are widely used.
