With respect to the advancements in the field of fertilization, biological fertilization is now widely used with chemical fertilization. However, a new method of fertilization has also been suggested, which is the use of the innovative field of nanotechnology with biological fertilization. Accordingly, the objectives were to: 1) evaluate the effects of nano fertilization in combination with the soil microbes on pinto bean morphology and physiology under field drought conditions, 2) compare the innovative field of nanotechnology using nanobiologic with chemical fertilization. The experiment was a split plot on the basis of completely randomized block design in three replicates. Different levels of drought including the evaporation at 60 (control), 90 (medium) and 120 mm (high) from the class A pan were devoted to the main plots and different types of fertilization including: 1) control (0), 2) nanobiologic, 3) nanobiologic with 75 kg pure N (urea), 4) 150 kg pure N (urea), 5) 75 kg pure N with nano ZnFeMn (foliarly applied), and 6) 75 kg pure N with ZnFeMn (foliarly applied) were used as the subplots. Plant morphological and physiological parameters were determined. Plant relative water content was not affected by drought stress or fertilization type. Although different plant morphological and physiological parameters were adversely affected by drought stress, the nanobiologic fertilization was able to significantly increase such parameters compared with 150 kg/ha N and control treatments. Both increasing the stress level and using the nanobiologic fertilization increased the number of stomata in pinto bean compared with 150 kg/ha N and control treatments under stress. There were not differences between the method of application (seed treatments and foliar application). According to the results, the use of nanobiologic as a new method of fertilization is recommendable for bean production with economic and environmental benefits under different conditions including stress.
