Tomato (Lycopersicon Esculentum Mill.) is one of the popular fruit vegetables, especially rich in vitamins, minerals, and antioxidants. Inconsistent light intensity, due to unfavorable weather conditions, reduced tomato performance. Response of one tomato variety (Diamante Max F1), under different light intensities (T1: Control, T2: Single net T3: Double net,) was assessed in field trials. The experimental design was a randomized complete block design (RCBD). Effects of different light intensities were measured in terms of plant height, number of days to flower, number of fruits, the weight of fruits, yield per hectare, and light intensity received in every treatment. All results were significantly different at a 1% level of significance for all parameters. Treatment 2 manifested the highest mean for plant height, treatment 1 for the number of days to flower, and treatment 3 for the number of fruits. Treatment 3 obtained the highest yield per hectare and Treatment 1 for the highest light intensity received per treatment. Treatment 2 has the least mean for all parameters measured, in conclusion, the effect using a double net is highly recommended in tomato production.
