Abstract: PAITON, EMELYN P., Don Severino Agricultural College, Indang,Cavite April, 1990. "Determination of Water Consumptive Use Coefficient of Tomato" . Adviser Eng'r. Conrado M. Baltazar. A total land are of 100 square meters at the experimental field of the Don Severino Agricultural College, Cavite was used in the experiment to determine the water consumptive-use coefficient of a Panagulan variety of tomato. Actual Evapotranspiration (ETA) was determined by the soil moisture balanced method. The potential Evapotranspiration was computed' using the method developed by Blanney and Criddle. Generally ETA obtained were low during the early stage of growth. It gradually increased up the flowering stage with a value of 6.0 Mimi meters. The decreasing evapotranspiration rate was observed. The average value of measured ETA was 4.22 millimeters and total for the whole growing season was -291.25 millimeters:. The value of water consumptive-use coefficient (Kc) was 0.46 3 days after transplanting-. It increases until the flowering stage. The maximum value was 1.16 which occurred at 40 days after transplanting. This began to decrease until harvest at 69 days after transplanting with a value of 0.52. The polynomial regression equation of the third degree developed to describe the behavior of the water consumptive-use coefficient curve. One equation describes the left curve that is from transplanting to 48 days after. other equation describes the right curve, from 42 days after transplanting to harvest.
