ABSTRACT: The cultivation of Qañawa in Bolivia remained marginal for a long time, but its importance lies in its high nutritional valué, which is why in recent years this crop has regained importance. Unfortunately, at present one of the biggest problems is the low yields due to low soil fertility, climatic factors, among others. In this understanding, the agronomic behavior in the Qañawa crop was evaluated incorporating different amounts of organic fertilizer and urea as the main objective, this research was carried out at the Khipakihipani Experimental Station dependent on the PROINPA Foundation located in the city of Viacha-La Paz , for this, a randomized block design was used according to divided plots for field experimentation, taking three levéis of llama manure as factor A (0, 1 and 21 / ha) and three levéis of urea (0, 45 and 90 kg N / ha), the variables were plant height, phytomass yield, brushwood yield, grain yield, grain weight per plant, harvest Índex, grain diameter and grain weight covered per hectoliter, for the experimentation In the laboratory, a completely randomized design was used using the seeds obtained in the field as treatments where the viability of the seed was evaluated by the germination percentage at 24 and 36 hours and finally the economic analysis was evaluated. Plant height was influenced by manure levéis, urea levéis and the interaction of factors, phytomass yield, brushwood yield, grain yield and grain diameter were influenced by manure levéis and urea levéis, the Grain weight per plant was influenced only by manure levéis, the harvest Índex and grain weight per hectoliter were influenced by manure levéis, regarding the viability of the seed there were statistical differences in the treatments to the 24 hours and not at 36 hours, finally with respect to the economic analysis, treatment 9 is the most recommended.
