The objectives of this study were to (1) examine the light intensity and to (2) investigate the light period for the production of Wolffia globosa . The methodology of this research was divided into 2 steps: (1) the first step employed a completely randomized design (CRD) with 5 treatments and 4 replications including 4,000, 8,000, 12,000, 16,000 and 20,000 lux in order to select the light intensity level affecting the maximum marginal yields, and (2) the second step used a completely randomized design (CRD) with 5 treatments and 4 replications including 8, 10, 12, 14 and 16 hours per day, respectively. The data were collected twice per day as follows: temperature, pH and electrical conductivity of water quality for every 5 days for the 30-day period. The data were analyzed by means of analysis of variance (ANOVA) and Duncan's Multiple Range Test (DMRT) at the 0.05 level of significance. The results showed that the optimum light structure for the production of the aquatic macrophyte (Wolffia globosa) was light intensity 12,000 lux with 14 hours per day of the light period which produced maximum marginal the aquatic macrophyte yield (295.20±17.96 grams) and the aquatic macrophyte dry weight yields (11.44±0.66 grams).
