In the search to improve the use of natural resources and increase the yield and quality of the fruits using environmentally friendly techniques, such as grafting and the use of metal nanoparticles. The objective of this research was to determine the effect of grafting combined with the application of different concentrations of selenium nanoparticles (Se NPs) encapsulated in one gram of chitosan-polyvinyl alcohol hydrogel (CS-PVA) in the productivity and production of grafted cucumber. The treatments were applied to the substrate at the time of transplantation as follows: 1, 2.5 and 5 mg of Se NPs absorbed in one gram of hydrogels of CS-PVA, CS-PVA without NPs and a control treatment, in grafted and non-grafted cucumber plants. The variables evaluated were length and diameter of the stem, fresh and dry weight of leaves, foliar area, root length, fruit length, number of fruits and yield per plant. The results showed that the application of Se NPs has a beneficial effect for plants, as a growth-promoting agent and that together with the graft help to obtain a higher plant height and fruit weight, obtaining a higher yield per plant.
