          Abstract

          El trabajo se desarrolló en el Instituto Nacional de Ciencias Agrícolas (INCA) con el objetivo de evaluar las respuestas provocadas en el rendimiento, producto de las variaciones de las temperaturas durante el ciclo del cultivo. Se utilizaron plantas de tres variedades de papa Call White, Spunta y Santana cosechadas durante los años 2010, 2011 y 2012, respectivamente. Se evaluó el comportamiento de las temperaturas mínimas, medias y máximas así como la amplitud de estas, además se determinó el rendimiento promedio por planta en kilogramos y se infirió en t.ha-1. Todo el procesamiento estadístico se realizó con el empleo del programa Statgraphycs v5.1 y los gráficos se realizaron con el programa Sigma Plot v3.1

          Translated abstract

          The work was developed at the National Institute of Agricultural Sciences in order to evaluate the responses elicited in product yield variations in temperature during the crop cycle. Plants of three varieties of potatoes Call White, Santana and Spunta harvested during the years 2010, 2011 and 2012 respectively were used. The behavior of minimum temperatures, average of temperature and maximum temperature, amplitude of these and accumulated temperature too, were evaluated. The average of yield per plant in kilograms and inferred in t.ha-1 were determined. All statistical processing was performed with the use of the program Statgraphycs v5.1 and graphics were performed with the program Sigma Plot v3.1

              Potato potential yield based on climatic elements and cultivar characteristics

              There is currently a great deal of interest in estimating crop productivity as a function of climatic elements by means of different crop weather models. An agrometeorological model is presented based on carbon dioxide assimilation maximum rates for C3 plants, fraction of photosynthetically active radiation, air temperature, photoperiod duration, and crop parameters under tropical climate conditions. Such crop parameters include leaf area and harvest indexes, dry matter content of potato tubers, and crop cycles to estimate potato potential yields. Field data from observed productivity obtained with the cultivar Itararé (IAC-5986), grown under adequate soil water supply conditions at four different regions in the State of São Paulo (Itararé, Piracicaba, Tatuí, and São Manuel), Brazil, were used to test the model. The results revealed an excellent performance of the agrometeorological model in study, with an underestimation of irrigated potato productivity less than 10%.
