| Abstract | Zinc is an essential element for crop production and optimal size of fruit, also it required in the carbonic enzyme which present in all photosynthetic tissues, and required for chlorophyll biosynthesis (Graham et al., 2000; Ali et al., 2008; Mousavi, 2011; Xi-Wen et al., 2011). In addition, zinc will contribute on the pollination by impact on the pollen tube formation (Marschner, 1995; Outten et al., 2001; Pandey et al., 2006). Nanomaterials are cornerstones of nanoscience and nanotechnology. Nanomaterials are of interest because at this scale unique optical, magnetic, electrical, and other properties emerge. These emergent properties have the potential for great impacts in electronics, medicine, agriculture, and other fields. Nanoparticles (NPs) with small size and large surface area are expected to be the ideal material for use as a Zn fertilizer in plants. It has been stated that application of micronutrient fertilizers in the form of NPs is an important route to release required nutrients gradually and in a controlled way, which is essential to mitigate the problems of fertilizer pollutions (Naderi and Abedi, 2012). In calcareous soils solubility of micronutrients is similar Zn far less due to high pH, and this reduces ability of nutrient uptake by plants and naturally plants requirement increases to these elements (Alloway, 2008 and Mousavi et al., 2007). Foliar spraying of fertilizers has been considered an important strategy to biofortify crops, because it has Abstract In order to investigate the effect of zinc nano-chelate foliar and soil application on qualitative and quantitative characteristics of maize (Zea mays L.) at different grown stages, an experiment was conducted in the factorial form based on a completely randomized block design with three replications during growing seasons of 2013-2014. Treatments were nano-chalate zinc application in four levels: a1: soil application, a2: foliar application, a3: soil application + foliar application, a4: control and different growth stage in three levels contain b1: 8-10-leaves stage, b2: taselling and b3: SA grain filling stage. The analysis of variance showed significant effect of Zn nano-chalate application and different growth stage on stem dry weight. Also, effect of Zn-chalate application on husked ear weight, ear length, cob dry weight and grain to cob weight ratio was significant (p<0.01). The detailed results of the study showed that Zn nanochalate foliar application at 8-10 leaves stage had more stem dry weight (34%). Moreover, Zn nano-chalate foliar application had 54%, 13%, and 39% more husked ear weight, ear length and cob dry weight, respectively. |
