Rye production under acid soils and drought conditions: An alternative for the sustainability of High Andean livestock farming in Peru por Carrasco Chilon, William Leoncio, Alvarez García, Wuesley Yusmein, Cervantes Peralta, Marieta Eliana, Quilcate Pairazamán, Carlos Enrique, Vásquez, Hector V.

“…The rye (Secale cereale L.) crop shows a high potential to contribute to the sustainability of high Andean livestock because it supports the agroclimatic conditions and acid soils in the Peruvian Andes. The production of green forage, hay, and grain from the rye crop in acid soils was studied with the use of different levels of phosphorus and potassium fertilization in four local rye ecotypes (CBI-001, CSM-001, CJS-001, and CCE-001). …”

Short Communication: Prediction of body weight using morphometric measurements in Creole goats from Peru por Paredes Chocce, Miguel Enrique, Sessarego Davila, Emmanuel Alexander, Tafur Gutierrez, Lucinda, Temoche Socola, Victor Alexander, Salinas Marco, Jorge, Acosta Granados, Irene Carol, Ruiz Chamorro, Jose Antonio, Cruz Luis, Juancarlos Alejandro, Trillo Zarate, Fritz Carlos

“…The selected candidate model met all established tests and, upon validation, reached an r² of 0.66 (p<0.001), indicating that the model can adequately predict the BW of Peruvian Creole goats and serve as a practical tool to support selection programs, feeding strategies, and market decision-making in smallholder systems.…”

Mapping of suitable release areas for the parasitoid Dolichogenidea gelechiidivoris (Marsh) for the classical biocontrol of Tuta absoluta (Meyrick) using temperature-dependent phen... por Mujica, N., Carhuapoma, Pablo, Kroschel, Jürgen, Kreuze, Jan F.

“…Dolichogenidea gelechiidivoris (Marsh) is a larval endoparasitoid native to the Neotropics, where it is the dominant biological agent of T. absoluta along the Peruvian coast. The determination of the parasitoid’s temperature-dependent development is crucial for better predicting the potential of the parasitoid to establish in new regions and to control the target pest. …”

Can Regenerative Agriculture in Andean Potato Farming Enhance Productivity, Profitability, and C Sequestration While Reducing Carbon Footprint? A Case Study from Northern Peru por Briceño, P., Ninanya, J., Seminario, J.F., Otiniano, R., Rinza, J., Mestanza, C., Arias, E., Villanueva, C., Mendoza, W., Mendiburu, F. de, Kreuze, Jan F., Ramirez, D.

“…This two-trial study evaluated the potential of regenerative agricultural practices for potato production in the Peruvian Andes over two seasons (2022–2024), in terms of productivity (FTY: Fresh tuber yield), profitability (BCR: Benefit-cost ratio), C footprint (CF), and soil properties. …”

Molecular and pathobiological characterization of sixty one potato mop-top virus full-length cDNAs reveals great variability of the virus in the center of potato domestication, nov... por Kalyandurg, P., Gil, J.F., Lukhovitskaya, N.I., Flores, B., Muller, G., Chuquillanqui, C., Palomino, L., Monjane, A., Barker, I., Kreuze, Jan F., Savenkov, E.I.

“…Interestingly, all isolates characterized previously (from Europe, Asia and North America) fall into the S-type clade, whereas most of the Peruvian isolates belong to the M-type. Taken together, our results support the notion of the single introduction of PMTV from the centre of potato origin to Europe, and subsequent spread of the S-type into Asia and USA. …”

Land cover change interacts with drought severity to change fire regimes in Western Amazonia por Gutiérrez Vélez, Victor Hugo, Uriarte, M.A, DeFries, Ruth S., Pinedo Vasquez, M., Fernandes, K., Ceccato, P, Baethgen, Walter E., Padoch, Christine

“…We then combined these maps with land cover and climate information to understand the influence of land cover change in cleared lands and dry‐season severity on fire occurrence and spread in a focus area in the Peruvian Amazon. Fire occurrence, quantified as the probability of burning of individual 232‐m spatial resolution MODIS pixels, was modeled as a function of the area of land cover types within each pixel, drought severity, and distance to roads. …”

Identification of Elite Potato Clones with Resistance to Late Blight Through Participatory Varietal Selection in Peru por Gastelo Benavides, Manuel Antonio, Burgos, Gabriela, Bastos Zuñiga, Carolina, Perez, Juan Miguel, Otiniano Villanueva, Ronal, Cabrera Hoyos, Héctor Antonio, Ccanto, Raul, De Scurrah, María Mayer, Zum Felde, Thomas

“…During 2016–2017, 36 clones previously selected for high levels of resistance to late blight from population B developed by the International Potato Center, and three varieties used as controls (INIA 302 Amarilis moderately resistant, INIA303 Canchan and Yungay susceptible to late blight), were evaluated in five Peruvian locations. At harvest, five clones were selected based on (i) evaluations made by farmers through Participatory Varietal Selection, (ii) analysis of mixed models and Best Linear Unbiased Predictors for tuber yield, (iii) low glycoalkaloid content in tubers, and (iv) good organoleptic quality. …”
