Agromorphological characterization of cacao accessions in Peru is currently an important tool in the conservation and genetic improvement of cacao germplasm. The objective of this study was to carry out the morphological and agronomic characterization of 113 cacao accessions from the Huarangopampa germplasm bank. Tree, leaf, flower, fruit and seed descriptors were used. The data collected were processed by descriptive statistics using multivariate techniques. Five groups were formed according to similar characteristics. The accessions of group 1 are vigorous trees with an pod index of 19.27 pods/kg of seeds; the groups that presented better differential characteristics were group 2 with erect tree architecture, intermediate vigorousness, purple seed color and pod index of 20.07 pods/kg of seeds and group 3, which had the highest number of accessions with the lowest pod index of 18.77 pods/kg of seeds, besides being vigorous trees and having purple seeds. On the other hand, group 4 presented a particular characteristic of white seed color and high pod indexes with 22.11 pods/kg of seeds. Finally, group 5 accessions were characterized by intermediate tree architecture and vigor with an pod index of 21.3 pods/kg of seeds. The morphoagronomic characterization constitutes a first advance in the identification of cacaos with potential for genetic improvement and advances in the Peruvian chocolate industry.

(Instituto Nacional de Innovación Agraria, 2021-07) Yoplac, Ives Julian; Chávez Santos, River; Santos Peláez, Julio César
El Ministerio de Desarrollo Agrario y Riego (MIDAGRI) a través del Instituto Nacional de Innovación Agraria (INIA), pone a disposición el presente “Manual de cosecha y poscosecha de pitahaya amarilla (Hylocereus megalanthus)”, como un documento técnico que describe de manera didáctica y mediante un lenguaje claro, los diferentes procesos de cosecha y poscosecha de esta fruta prometedora en muchos valles del Perú. Esperamos que esta contribución llegue a generar una motivación para los productores, técnicos, profesionales e investigadores quienes están interesados en conocer los procesos de cosecha y poscosecha de la pitahaya amarilla.
Promising physicochemical technologies for poultry slaughterhouse wastewater treatment: A critical review
(ELSEVIER, 2021-02-06) Terán Hilares, Ruly; Atoche Garay, Diego Fernando; Pinto Pagaza, Daniel A.; Ajaz Ahmed, Muhammed; Colina Andrade, Gilberto J.; Santos Peláez, Julio César
Poultry slaughterhouse wastewater (PSWW) is a serious concern mainly due to the huge generation and associated characteristics of high organic matter and nutrients (N, P) that this contains. Therefore, an understanding development and adaption of an apposite wastewater treatment option focused specifically on PSWW is an absolute need. Recently, innovative physicochemical-based technologies, such as; acid precipitation, electrochemical advanced oxidation, cavitation-based processes and even nanotechnology assisted processes have been reported as prominent alternatives for wastewater treatment. In this article, we performed a systematic literature review and a comprehensive discussion about these technologies, aiming to show them as alternatives for PSWW treatment. Among all discussed technologies, hydrodynamic cavitation (HC) was observed as an interesting possibility that can be implemented in combination with other processes for efficient pollutant degradation. It could be, e.g., associated with nanoparticles, nanocomposites and nanobubbles, which are also an interesting alternative to be associated with membranes, generating turbulence, and mitigating problems as fouling. Finally, the wide knowledge about such treatment technologies can offer a more cost-effective PSWW management, thus, allowing an adequate implementation from technical and economical viewpoints.
