This study was conducted in the community of Yampupata, in the municipality of Copacabana, in the Manco Kapac province, La Paz, to an altitude of 3841 m.a.s.l, agricultural campaign 2003-2004. The purpose of the study was to determine and compare the fenological stages (germination, growth, leafing, and harvesting), hypocotyl yield (dry and fresh), classification of the hypocotyl (diameter, length, etc.), and the economical evaluation as well. The experiment set up was installed in the lower region of the community, dedicated to agriculture, performing all the aforementioned activities together for the period of a year. The experimental design was of Random blocking test, having three types of Maca (lepidium mevenni Walp.): yellow, purple, and cream , five levels of ovine manure ( 0.0, 2.5, 7.5, and 10.0 tn/ha), distributed in the four blocks, 15 treatments, 60 experimental units, with a planting density of 3 kg/ha, and a total area of 300 m². According to the results, it is recommended to plant the cream, and the yellow ecotype of Maca, due to their positive development under the conditions of the soil, and climate of the zone. The cream ecotype under the effect of 7.5 tn/ha of ovine manure (a3b3) had a yield of 8055.06 kg/ha in 238 days (8 months) , with a rentability index of 3.75. In comparison, the purple ecotype with a 0.0 tn/ha of ovine manure (a2b1) had a yield of 4319.55 kg/ha, and a rentability index of 1.74 in eight months. The cream ecotype with 7.5 tn/ha of ovine manure, presented the best behavior under local conditions (climate, soil, and handling), the yield and rentability index were superior to the other treatments; therefore, it is recommended to implement a production plan in the sector according to the results obtained from the study.
