Efecto del laboreo sobre la calidad del suelo y la producción de quinua (Chenopodium quinoa), bajo dos sistemas de siembra en la parroquia Santiago de Quito, provincia de Chimborazo

Abstract

The present research is aimed to evaluate the effects of working about quality of soil, using two sowing methods in the (Chenopodium quinoa Wild) quinoa production, parish Santiago de Quito, Colta canton, Chimborazo province by using a plot design divided in bifactorial arrangement with 6 treatments and 4 repetitions. In the soil quality evaluation, by analyzing physic, chemical and biological factor the soil of the experiment area was considered of low quality for the quinoa cultivation. The following variable were analyzed: percentage of emergency, days to flowering size of panicle, days to harvest, plant height, root size, net performance, performance per hectare; in chemical properties: pH, , organic-matter content and N,P,K content; in physical properties: texture, structure and shear strength; and in the biological properties; number of worms and insect in larval state. The best treatment for quinoa cultivation was that minimum farming + sowing in lines (T2) reaching 160cm in plant height and more performance per hectare with 1992 kg and with 674%. In addition the essay got an average of 82.5% for the days to the emergency, 79 days to the panicle, 12.28 cm of height of panicle, 115cm of plant height, 15.5 cm of height of root and 170 days to the harvest. It is concluded that the best agronomic answer in this harvest was gotten with the minimum farming and the sowing in lines, while traditional farming with in furrow sowing got the best marginal rate
