Abstract
The study of the synergistic and antagonistic effects of using nutrients, respectively, to better absorb or prevent the absorption of other elements, and the optimal balance between nutrients and plant yield has always attracted the attention of biological and agricultural sciences researchers. In this research, effects of nitrogen sources in four levels including: 100% urea fertilizer (N1), nano-chelate nitrogen fertilizer (N2), 100% panaromix biological fertilizer (N3) and 50% urea + 50% panaromix biological fertilizer (N4) and zinc sources in three levels including: without application of Zn fertilizer (control) (Z1), zinc sulfate fertilizer (Z2) and nano-chelate zinc fertilizer (Z3) and interaction effects of sources of these two elements on physiological behavior and yield of wheat (Triticum aestivum L.) and interaction of these elements as a split-plot factorial based on completely randomized blocks design with 3 replication and 12 treatments is studied. Results showed that leaf area and number of leafs, shoot length, chl b and chl (a + b) content and nitrate reductase activity as well as biological yield and grain yield were affected by the sources of nitrogen supply and the interaction effects of sources of these two elements (N*Zn) and in treatments containing 100% urea and 50% urea + 50% biological fertilizer that were used as a source of nitrogen supply, showed highest content but in all of these traits, there was no significant difference in sources of zinc supply. The results of the present study indicated that in treatments of the interaction effects of sources of these two elements (N*Zn), the highest of chl b and total chl (a + b) content and nitrate reductase activity were observed in Z2N1 (100% urea + zinc sulfate fertilizer) treatment. The highest economic yield and biological yield were also associated with the same treatment. The results indicated that there was synergistic interaction between N and Zn and high yield of plant in Z2N1 treatment is a function of plant physiological behavior.
