The present work aimed to structure a low cost and ecologically correct hydroponic production system with reuse of materials, available at the UTFPR - Londrina Campus. The experiment was carried out in the city of Londrina-PR, in an open area with high light intensity. After the construction of the hydroponic system, all possible leaks and blockages were checked, with the aim of remedying the problems and starting crops. Also, by the experimental method (volume/time) the flows of each tube in the hydroponic system were calculated. The nutrient solutions used in the system were 50 grams YaraTerra "Kristalon" Mixed Mineral Fertilizer, 50 grams YaraTerra "Calcilit" Simple Mineral Fertilizer (Calcium Nitrate) and 0.8 mL NutriPlant "Green Top MicrosQ" Liquid Foliar Fertilizer. After checking all the processes, the crisp lettuces were transplanted to the stage known as the nursery, where they remained for a period of 30 days and then harvested. Daily, the pH and electrical conductivity of the nutrient solution were analyzed, and subsequently, an amount considered essential for the development of the lettuce crop was inserted. After harvesting, the variables wet weight and dry weight of roots + stems and leaves were evaluated. The reuse of civil construction waste resulted in a reduction of R$ 238.17 in costs for the construction of the hydroponic system, totaling a 47.5% reduction. For the analyzed parameters, the flow and pH presented good results, but the electrical current obtained divergent data due to the fact that monitoring is manual. Finally, the statistical analyzes showed uniform results in dry matter, but in green matter there was a significant difference. |
