Abstrak: The study aims to determine the effect of the combination of cow compost and fertimix solution on the growth and production of two cultivars of lettuce (Lactuca sativa L.) on a raft floating hydroponic system. The first factor is lettuce cultivars New Grand Rapid and Chia Thai Seed cultivar. The second factor is composed of the combination of 0 ppm composted cow solution and 2000 ppm nutrient solution Fertimix as a control, a solution of 500 ppm cow compost and 1500 ppm nutrient Fertimix solution, solution of 1000 ppm cow compost and 1000 ppm nutrient Fertimix solution, solution 1500 ppm cow compost and 500 ppm nutrient solution Fertimix, and a solution of 2000 ppm cow compost and 0 ppm fertimix solution. Giving a combination of cow compost and Fertimix solution lowering effect of plant height, leaf number, root length, shoot fresh weight and root dry weight. Thai Chia seed cultivars and New grand rapid no effect on plant height, leaf number, root length, fresh weight and dry shoots, roots and stover. Giving a combination of 0 ppm cow compost solution and 2000 ppm Fertimix solution with lettuce cultivars effect on plant height, root fresh weight and wet weight stover, and shoot dry weight and dry weight of stover.
