ABSTRACT: The research work was conducted on the premises of the Choquenaira Experimental Center - UMSA, with the objective of evaluating the effect of Biol incorporated in foliar form in twenty promising genotypes of cañahua in the 2018-2019 agricultural season. The research was established under a randomized complete block design with factorial arrangement and applying the Duncan multiple comparisons test (5%) for thirteen variables. The first study factor consisted of three Biol concentrations (60%, 40% and 20%) and two controls, and the second factor consisted of twenty promising cañahua genotypes. It was observed that Biol increased the average grain yield of the crop by 32.5% compared to the absolute control. It was also recorded that the 40% concentration of Biol had a favorable effect on the morphological development of the cañahua plant, reaching an average yield of 1691.3 kg ha^-1. The Pusar genotype presented the highest average grain yield with 2455.1 kg ha^-1, on the other hand, the L-14 genotype reached a grain yield of 3005.23 kg ha^-1 in combination with the 40% Biol concentration. Biol as a foliar fertilizer is a sustainable alternative to partially replace the use of chemical fertilizers in order to improve productivity in the cultivation of sugarcane
