MEZA, Norkys et al. Growth and yield of potato varieties in Cuencas, Urdaneta township of Trujillo state, Venezuela. Agronomía Trop. [online]. 2013, vol.63, n.3-4, pp.177-183. ISSN 0002-192X.

Potato production (Solanum tuberosum L.) is part of culture and way of life of Andean horticulturists. It is a strategic crop forbeing a source of carbohydrates, proteins and vitamins. Potato has versatile forms of consumption and wide adaptability to different agro-ecological conditions. To evaluate local varieties Montañita and Sin nombre from Táchira state, and commercial varieties Tibisay, Maria Bonita, Única peruana, Granola and Maria Reiche, a trial was conducted in Cuencas, Urdaneta township, Trujillo state, Venezuela; 1,627 meters above sea level, relative humidity 80-90% and temperature 14-16 °C, with an experimental design in random blocks with 4 replications; 4 rows per 3 m length plots and 10 tubers per row, planted at 0.80 x 0.30 m. The evaluation was performed by methodology proposed by International Potato Center (CIP). Highest percentages of emergency were found in Única peruana (97.50%), María Reiche (91%) and Tibisay (90%). Sin nombre, María Reiche and Tibisay achieved the greatest heights; while Sin nombre the highest number of stems and tubers. Best yields were achieved in Montañita (19,246.43 kg h^-1) and Única peruana; (17,413.32 kg h^-1) and the lowest yield was obtained by María Bonita variety (10,276.19 kg h^-1). Única peruana and María Reiche produced highest percentage of potatoes for consumption and were suitable for industrial processing in the production of sticks. Other varieties can be used for flakes production.
