Item Determinación de la eficiencia de la técnica de riego solar en la producción de lechuga (Lactuca sativa) en agricultura urbana(2021-09) Cordero Arévalo, María De Los Ángeles; Santana Mayorga, Rita CumandáThe present research refers to the implementation of an irrigation technique known as Kondenskompressor or solar drip irrigation for one of the most produced vegetable crops in the area of urban agriculture: Lettuce (Lactuca sativa). Which is based on the evaporation of water placed in plastic bottles (PET) recycling product as bases covered by a hood of the same material, which through the incidence of solar energy inside causes a greenhouse effect, very similar to the operation of the solar distillers in which the air is heated and the water evaporates condensing in the bell to form drops each time large which causes precipitation on its walls. In this trial, two study factors were evaluated: the number of bottles B1 (one bottle), B2 (two bottles), B3 (three bottles) per pot and volume of water D1(100 cc), D2 (200 cc), D3(300cc) resulting in nine treatments combining both factors. Although there were no statistical differences between treatments, one of the best results was obtained from the B2D1 treatment, but still did not provide enough water to obtain the expected results in the crop, so we determined that it is not efficient for lettuce cultivation due to the high demand for water from the crop and the climate (rain and cloudy sky) of the sector in which the test was conducted, they no longer allowed its full development due to lack of solar energy.
