Abstract
The increase in the cost of fertilizers and their low efficiency has led, through nanotechnology, to the generation of new innovative products that are sustainable and improve the productivity of crops. Therefore, the objective of the present study was to evaluate the efficacy of a molybdenum nanofertilizer compared to two conventional fertilizers (chelate and sodium molybdate) applied via foliar combined with soil fertilization of NH4NO3 in relation to the Nitrogen Use Efficiency, growth and yield in green bean cv. Strike. Green bean plants cv. Strike were cultivated under controlled conditions in an experimental greenhouse and irrigated with nutrient solution. The treatments consisted of the foliar application of three Mo sources (Nano fertilizer, Mo Chelate and Sodium Molybdate) in four doses 0, 5, 10 and 20 ppm Mo, complemented with the edaphic application of four doses of NH4NO3 (0, 3, 6 and 12 mM of N). The results obtained indicate that the highest accumulation of biomass and yield were obtained with the application of NanoMo, with increases in biomass of 24.31% and 36.47% more in yield with respect to Chelate and Molybdate. Finally, it is concluded that the application of NanoMo improves the assimilation and efficiency of nitrogen use, reducing excessive applications of nitrogenous fertilizers without affecting the yield of the green bean crop.
