Rev. Inv. Cs. Agro. y Vet. [online]. 2021, vol.5, n.13, pp.78-90. ISSN L:2664-0902.  https://doi.org/10.33996/revistaalfa.v5i13.99.

The investigation called Effects of the application of different levels of potassium fertilization on the yield and quality of fruits in the cultivation of pepper (Capsicum annum L.) Var: Híbrido Nathalie, in the district of Pilar, agricultural year 2017/2018, was presented to the Faculty of Agricultural Sciences and Rural Development, National University of Pilar. Experimental research, focused on the evaluation of various parameters in the production of the hybrid Nathalie variety pepper, with the application of different levels of potassium fertilization, the results obtained assess the influence of said treatments on the quality and yield of the crop of pepper. The doses used were the following 50, 75, 100, 125, and 150 kg / ha, including a control which was the treatment without application of potassium fertilizer, thus having six treatments and five repetitions distributed in random blocks. This analysis was verified with statistical tests, analysis of variance and the comparison of means through the Duncan test at 5%. Regarding quality, the means of length, diameter and wall thickness of the fruit did not show great differences, highlighting that the T4 (100 Kg / ha) always presented a higher level between the treatments, and in terms of yield the analysis of variance showed that there is no significant difference between the treatments, however, the T4 had the highest yield with 55,225 Kg / ha where the comparison of means indicated that it presented a significant difference over the control.
