<br/><br/> ANACAN, JERWIN C., Performance of Drip-Irrigated Lettuce Under Various Soil Substitutes. Undergraduate Thesis. Bachelor of Science in Agricultural Engineering, Cavite State University, Indang, Cavite. February, 2007. Adviser: Dr. Leyma L. Cero. <br/>The study was conducted at CvSU, Indang, Cavite from January 26, 2006 to February 24, 2006. The study aimed to: a) evaluate the performance of lettuce grown under the drip irrigation system; b) determine the growing medium suited for growing lettuce under drip irrigation system; and c) determine the cost of the study. The study was conducted with four treatments having three replications each. The treatments were: T1 (pure coir dust), T2 (50 % coir dust and 50 % carbonized rice hull), T3 (50 % coir dust and 50 % saw dust) and T4 (50 % coir dust, 25 % saw dust and 25 % carbonized rice hull). The treatments were arranged in Completely Randomized Design (CRD). <br/>The study revealed that the plant height, number of leaves, leaf diameter, leaf length, root length and yield were significantly affected by the different growing media. Lettuce grown in treatments having a mixture of coir dust and carbonized rice hull produced the greatest yield. The fixed cost and the variable cost of the study amounted to P 7,273.50 and P 2,161.55, respectively, giving a total cost of P 9,435.05. <br/><br/><br/>
