This research is based on the evaluation of drip irrigation systems on growth and crop production of quinoa (Chenopodium quinoa Willd). It was conducted during the period from June to October 2014, in the experimental fields of the National Agricultural Innovation Program Crops (PNIA), District of La Molina. Evaluating two irrigation systems: drip (RI) and exudation (RO) in divided with four blocks (B1, B2, B3, B4) plots. The variables studied were: crop water demand, application efficiency, plant height, root length, dry biomass, canopy cover (CC), leaf area index (IAF), harvest index (IC) performance heat units (D °) required to reach each stage of development and financial analysis benefit / cost (B / C). Once the study is completed, the variables under study reached the following results: total volume of water applied under the irrigation system by exudation to 1571.6 m3 / ha and drip 1708.5 m3 / ha. Application efficiency obtained was 81% and 78% drip for exudation. Canopy coverage to 80 DDS was higher (88.5%) for bleeding compared with dripping (69.8). The optimal leaf area index had to be 73 DDS (2.9) under exudation and (2.5) under drip irrigation, harvest index by exudation was highly significant with a value of (0.5) unlike drip (0.3). The irrigation system by exudation had the highest performance with 3519.3 Kg / ha followed by dripping with 1587.9 Kg. / Ha. More efficient water use (USA) was under irrigation by exudation with 2.2 kg / m3 and the lowest in dripping with 0.9 kg / m3. The cultivation of quinoa variety Inia 431- Altiplano, requires on average a total of 1178.8 degrees of heat accumulated day the crop requires to complete its cycle. The financial analysis B / C and profitability determine the best irrigation system is oozing with 2.9 B / C and 190% return and secondary drip irrigation with 2.4 B / C and 186% return. Water demand, efficient water use, crop development and financial analysis benefit / cost responded positively in the production of quinoa under the irrigation system by exudation unlike drip irrigation.
