Fertilization with nanoparticles offers alternatives to improve the efficiency of nutrient absorption in a sustainable way in crops. The objective of this work was to study the influence of foliar application of zinc-molybdenum nanofertilizer (Nano ZnMo) on nitrogen (N) use efficiency (NUE), as well as on yield parameters and N assimilation in green bean plants cv. “Strike”. Three doses of Nano ZnMo (0, 4 and 8 ppm) were applied foliar in combination with four doses of N in the form of NH4NO3 in nutrient solution (0, 3, 6 and 12 mM). The treatment that obtained the greatest increase in total biomass was the combination of 6 mM N + 4 ppm Nano ZnMo, with an increase of 11.6% compared to the treatment without application of Nano ZnMo. The treatment that registered the highest yield was the combination of 3 mM of N + 4 ppm of Nano ZnMo with an increase of 39.3% compared to the treatment without foliar application of Nano ZnMo (3 mM of N). The utilization coefficients (NUtE) and NUE were favored with the foliar application of Nano ZnMo at 4 ppm in combination with 3 and 6 mM of N in nutrient solution. These treatments made it possible to reduce the dose of N fertilization without compromising production. Therefore, the foliar adhesion of Nano ZnMo makes it possible to improve the efficiency of nutrient absorption and sustainably increase crop productivity.
