Evaluación de la adaptación y rendimiento de diez líneas de quinua (Chenopodium quínoa W), en la parroquia Calpi cantón Riobamba provincia de Chimborazo.

Abstract

The present investigation aims to evaluate the adaptation and performance of ten lines of quinoa (Chenopodium quinoa Wiild.), in Calpi parish, Riobamba canton, Chimborazo province. We used a completely randomized block design with 13 treatments and four repetitions and evaluated the following parameters: days after panicle, days after blooming, length and width of the leaf, height of the plant, length of panicle diameter of panicle, presence of plagues, severity of attack of mildew, days after crop, performance per plot, saponin content in the grain and the economical analysis according to cost benefit relation. The treatment with few days after panicle, blooming, and severity of mildew is T12 (Pata of venado). Deer foot, with average of 65.80, 131 days and 3.5 of the scale 1-9 respectively, while T8 (LQEP4) presented high length and width of the leaf with averages of 8.37 and 7.42 cm respectively. On the other hand, T4 (EQ28) showed less height with an arithmetic average of 105.85 cm and the treatment with higher length and diameter of the panicle as well as high content of saponin was T13 (Chimborazo) with averages of 35.9, 16.33 cm and 0.1% respectively. While treatment T9 (LQEP8) showed high performance with an average of 1147.22 kg/ha. Finally, when we carried out the economic analysis, the treatment T9 (LQEP8) was the best because it had a cost benefit with a high profitability of 1.04 USD of utility per each dollar invested under environmental conditions of Calpi parish, Riobamba canton, Chimborazo province.
