JF - Revista Brasileira de Engenharia de Biossistemas JA - Braz J Biosyst Eng VL - 15 IS - 1 SE - Regular Section DO - 10.18011/bioeng2021v15n1p142-153 UR - https://seer.tupa.unesp.br/index.php/BIOENG/article/view/989 SP - 142-153 AB - <p>The use of cow urine can be considered an agricultural practice of low cost for farmers in Southwest Paraná. This work aimed to evaluate the effect of cow urine on growth and production of lettuce seedlings. The experimental design was completely randomized with four replications. We analyzed the effects of seven cow urine concentrations (1,0, 2,0, 3,0, 4,0, 5,0, 6,0 and 7,0%) (v v<sup>-1</sup>). In the conditions of Southwest Paraná, the best lettuce development was obtained with the application of 5,0% concentration. Chlorophyll indices (a and b), were also higher with the use of concentration 5,0% concentration.</p> ER -
