Influence of Micronutrients Foliar Application and Nitrogen Fertilization on Wheat Yield and Quality of Grain and Seed

Response of wheat to foliar application of zinc

“…According to OZTURK et al (2006), the highest wheat yield is closely related to the cultivar potential to produce fertile tillers, which also influences directly the number of spikes produced per unit area. Significant increases in wheat grains yield to foliar Zn application were reported in other countries including Egypt (SEADH et al, 2009;ZEIDAN et al, 2010) and China (ZHAO et al, 2011) corroborating data obtained in this study to the Brazilian conditions. Such effects of foliar Zn application may be due to its role in crop growth (CAKMAK, 2008), involving processes of photosynthesis, nitrogen assimilation, respiration and activation of other biochemical and physiological processes and hence their importance in obtaining greater yields.…”

“…The increase in the number of spikes per unit area was due to the higher number of fertile tillers per plant at the end of the cycle. Similarly, SEADH et al (2009) showed that foliar Zn application provided 21% increase in the number of wheat spikes per m -2 . The lowest Zn supply to wheat plants promotes reduction in the number of tillers mainly because stems become thinner and lose their turgidity, a phenomenon called soft stems (RÖMHELD, 2001).…”

Response of spring wheat to different soil and foliar fertilization

“…Seadh et al (2009) report that the wheat grain yield is the most favourably affected by fertilization with a high dose of nitrogen combined with multi-component foliar fertilization.…”

“…It is particularly essential to balance mineral fertilization with nitrogen, phosphorus and potassium (Arif et al, 2006). Many authors (Seadh et al, 2009;Khan et al, 2010;Rawashdeh and Sala, 2016) report that the application of microelements is also of great importance in growing this form of wheat. During the wheat growing season nutrients may be applied to soil (Rehman et al, 2010;Nadim et al, 2013;Islam et al, 2014) or on leaves (Seadh et al, 2009;Tahir et al, 2009;Ahmad and Irshad, 2011;Ali et al, 2013;Rawashdeh and Florin, 2015).…”

Mineral fertilization should be performed according to the wheat plant needs, at suitable rates, proportions and times (Ralcewicz et al, 2009).…”
