ResumenAntecedentes: La papa (Solanum tuberosum L. grupo Andigena y Phureja) es un tubérculo de vital importancia en Colombia y en especial en el departamento de Boyacá. En la Universidad Pedagógica y Tecnológica de Colombia (UPTC) se cuenta con más de mil trabajos de grado, realizados en los 55 años de trayectoria del programa académico de Ingeniería Agronómica, entre los cuales 130 corresponden a investigaciones relacionadas con este cultivo. Objetivo: se recopiló información de dichos trabajos de grado desarrollados en este período y se analizaron 5 áreas de investigación: entomología, nutrición, fisiología vegetal, fitopatología y economía, en 3 lapsos de tiempo de 10 años cada uno y un último de 12 años. Resultados: En entomología se adelantaron 42 trabajos de grado (32,3%), siendo los de gusano blanco (Premnotrypes vorax Hustache) los más representativos. En el área de nutrición con 35 trabajos de grado (26,9%), se resaltaron los temas sobre correctivos de acidez y nutrición con elementos mayores N-P-K, haciendo énfasis en la evaluación del uso del fósforo. En fisiología vegetal se documentaron 20 trabajos de grado (15,4%), dentro de los cuales, se destacaron los temas sobre estadios fenológicos, crecimiento y desarrollo del cultivo de papa. En economía con 18 trabajos de grado (13,8%), fue más importante la evaluación económica y respuesta agronómica en fertilización, y finalmente en fitopatología con 15 trabajos de grado (11,5%), el tizón tardío (Phytophthora infestans) correspondió al patógeno más estudiado. Conclusión: Esta revisión brinda información a estudiantes, profesionales e instituciones involucradas con el sector papero colombiano y departamental, para la orientación y enfoque de futuros trabajos de investigación.Palabras clave: economía, entomología, nutrición, fisiología vegetal, fitopatología.AbstractBackground: Potato (Solanum tuberosum L. Andigena y Phureja groups) is a very important tuber in Colombia, mainly in the Boyacá department. At the Universidad Pedagógica y Tecnológica de Colombia (UPTC) students had developed over one thousand thesis, along 55 years of the agronomic engineer academic program, 130 of those related with potato crop. Objective: Information provided by those thesis during that period was taken together, and five research lines were analyzed: entomology, fertilization, plant physiology, phytopathology and economy in three timeframes of ten years and a last one of twelve years. Results: In the entomology area 42 studies were performed (32.3%), being Andean potato weevil (Premnotrypes vorax Hustache) the most representative. In the nutrition area with 35 studies (26.9%), the topics on soil acidity management were highlighted and plant nutrition with N-P-K elements, emphasizing in phosphorous use. In plant physiology 20 studies (15.4%) were documented, among which, phenology and potato growth and development were the most relevant. In the economic area with 18 studies (13.8%), the most important topic was economic evaluation and agronomic response to fertilization; and finally, in phytopathology with 15 studies (11.5%), late blight (Phytophthora infestans) was the most studied pathogen. Conclusion: This review brings information to students, professionals and institutions involved in potato crop production in Colombia and Boyacá, giving guidelines and focus for future potato research.Key words: economy, entomology, nutrition, plant physiology, phytopathology.Resumo Antecedentes: A batata (Grupo Solanum tuberosum L.

No presente trabalho são relatadas experiências com 12 variedades de batatinha (Solanum tuberosum L.), recebidas da Holanda (Prinslander, Irene, Froma e Barima), Alemanha (Merkur, Sabina, Linda e Concordia) e Suécia Konsuragis, Eigenheimer, Voran e Jätte-Bintje). Essas experiências, em número de seis, das quais três no chamado período "da sêca" (março-julho) e três no "das águas" (setembro-janeiro), foram executadas nas localidades de Campinas, Louveira o Capão Bonito, no Estado de São Paulo. Ficou evidenciado o seguinte: a) dado o bom estado de brotação dos tubérculos, as porcentagens de falhas no plantio "da sêca" foram baixas; já no plantio "das águas", as variedades de brotação lenta, como "Voran" e "Sabina", falharam muito; b) "Prinslander" e "Konsuragis" resistiram bem à sêca prolongada, e "Barima" o "Linda" mostraram ser muito sensíveis; c) "Linda", "Voran" e "Merkur", principalmente a primeira destas, apresentaram boa resistência a Phytophthora infestans, e "Jätte-Bintje" foi muito suscetível; "Voran", "Irene", "Prinslander" e "Barima" não ofereceram resistência a Alternaria solani; d) "Merkur" e "Konsuragis" foram as mais produtivas para as duas épocas de plantio, sendo que "nas águas", "Eigenheimer", "Barima", "Concordia" e Jätte-Bintje", também produziram bem. Outros aspectos relacionados com variedades foram estudados.

Summary. Potatoes (Solanum tuberosum L.) cv. ‘Delaware’ were grown over winter on a yellow Karrakatta sand amended with Alkaloam–gypsum (AG; previously referred to as red mud–gypsum) at up to 240 t/ha, both freshly-applied (2 experiments) and applied 2.5 years earlier (1 experiment). Several levels of phosphorus fertiliser (0–600 kg P/ha) were applied to the freshly-applied AG and a single level (600 kg P/ha) was applied to the previously-applied AG. Amendment of the soil with 60 t AG/ha (freshly-applied) doubled the amount of fertiliser phosphorus retained in the top 30 cm of soil when 100 kg P/ha was applied. On freshly-applied AG, bicarbonate-extractable phosphorus showed an upward trend with level of AG, being 16 mg/kg (0–15 cm) at 0 t AG/ha and 34 mg/kg at 90 t AG/ha. This will decrease phosphorus fertiliser requirements in the following potato crop by 49% relative to unamended soil based on previously published soil test standards. Amendment with freshly-applied AG increased the level of applied phosphorus required for 99% of maximum petiole phosphorus concentration by 46 and 139% in the 2 experiments compared with unamended soil. Maximum yield was significantly reduced by 7–10% at 60 t/ha of freshly-applied AG compared with unamended soil while on residual AG it was only reduced at 240 t/ha (12%) (trend only). Yield reductions were not correlated with a reduced availability of phosphorus, however, they may have been due to a reduced availability of potassium. The concentrations in the tubers of antimony, arsenic, cadmium, chromium, cobalt, lead, mercury and nickel did not exceed legal limits on soil amended with AG.

Background: In a Mediterranean agrosystem of low productivity, a study was carried out on the effects of municipal solid waste compost (MSWC) compared to other organic and inorganic amendments on the production, quality and yield of three potato varieties (Solanum tuberosum L.) and an advanced clone. Method: Simultaneously, the agronomic and nutritional parameters of the potato crop, the degree of bioavailability and the possible risks of heavy metal contamination were studied. Results: Two stages are observed in the yield and content of macro, micronutrients and heavy metals. The addition of all amendments and especially that of urban waste compost increased potato production and the content of macronutrients, micronutrients and heavy metals in the soils of all varieties, showing a progressive accumulation in tubers. Nevertheless, the performance is not maintained over time with a notable decrease during the second stage of its application. Conclusion: Highlighting the potato clone A7677 not only in its performance but also in the concentration of iron, zinc, copper, essential micronutrients for human consumption and especially for populations deficient in these trace elements.
