Abstract:                The objective was to evaluate the behaviour of the cultivation of the quinoa with different doses of semi-descompuesto manure.. The variables were plant height,,diameter and length of panicledepth, and, breadth of root,,severity of downy mildew,,, harvest index,, grain yield, grainsize and percentage of germination.. The research wasestablished under the design completely randomized withfour replicates blocks ,and used the Tukey mean test..Assessed (witness) T1, T2, T3, T4 and T5 with 2, 4, 6 and 8 t/ha ,manure semi-descompuesto. The results showed,,differences for the variables. The T4 showed the greater sizeof height with 105.67 cm, diameter of panicle of 4.39 cm and,24.31 panicle length cm. For root depth T5, T4, T3 and T2,,treatments had a good depth of 26.75 to 27.98 cm and thesee obtained an amplitude of 28.98 to 29.94 cm root.. Theseve-rity of the downy mildew affection most to T1 (witness),with a value of 33,47% was the most susceptible.The highestrate of harvet obtained the T4 of 0.54 who joined 6 t/ha.The T4 got 3744.15 to grain yield kg/ha then thetreatments T3, T2 and T5 are values of 2946.78, 2870.33 and2578.3kg/ha. In grain quality, the treatments showed-predominance in grain of big category with 25.73,24.80, and.24.43% by weight in the T4,T3 and T2 treatments.Where joined semi- descompuesto manure treatments T2, T3, T4 and T5 large grain germination percentage are similar. TheT4 with6 t/ha manure semi-descompuesto obtained thehighest benefit/cost of 4.24 Bs. Semi-descompuesto manure favored the expressions of agronomic variables.
