Fruit Quality of Tomato (Lycopersicon esculentum Mill) Applied with Combined Wild Peanut (Arachis pintoi) Extract and Inorganic Fertilizer Grown under Two Cultivation Systems

Romecita R. Rosalada


The study generally aims at evaluating the efficacy of Arachis pintoi extract as a supplement to organic foliar fertilizer combined with inorganic fertilizer on the fruit quality of tomato. The sensory qualities of tomato as affected by the application of different combination of organic and inorganic fertilizers were also evaluated. To achieve these objectives, two experiments were done simultaneously, in randomized complete block design (RCBD) under open field condition and protected cultivation with three replications and with 10 sample plants per treatment. Results showed that plants applied with foliar organic fertilizer Arachis pintoi performed better in terms of fruit quality, and fruit physico-chemical characteristics, and had longer shelf life than other treatments, but had lower lycopene content. The results also suggest that the type of cultivation has contributed to the fruit quality produced by the application of the different fertilizer treatments. Generally, those under protected cultivation had longer number of days to reach 50
