TRUJILLO-MEZA, Yordi Lennin et al. Organic sources and potato production in the Andean region. Rev. Mex. Cienc. Agríc [online]. 2022, vol.13, n.4, pp.735-740.  Epub Aug 22, 2022. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v13i4.3000.

The objective of the study was to evaluate the effect of three organic sources with three levels of application in the production of Yungay potato (Solanum tuberosum L.) under family farming conditions in the Andean region of Perú. A randomized complete block design with a 3x3 factorial arrangement plus one (1) additional treatment (control) was used. The number of stems and tubers per plant, yield and the category extra were evaluated. The experiment was conducted at 3 425 masl, in Huari, Ancash, Peru, from October 2019 to March 2020, under rainfed conditions. The superiority of the mean of the factorial over the control and the interaction between organic sources and application levels was observed, with the island guano standing out with 5 t ha-1.
