Petronila M Anuada, Pet Roey L Pascual and Danny E Carabio Abstract A field experiment was conducted at the Cebu Technological University-Barili Campus compound from April-June. The study determine the effect of combined organic fertilizer application on the growth and yield of cherry tomato (Solanum lycopersicum) as to height, days to flowering, number of flowers, days to first harvest, fruit per plant, and fruit weight. The study was laid out in a Randomized Complete Block Design (RCBD) with three replications. The results showed that the combined bat guano and fermented seaweed fertilizer produced the tallest plants at, 55.06±3.81SE cm. The earliest plants to produce flower were those treated with combined bat guano and fermented plant juice at 28.17±0.27SE days after transplanting. Also, combined bat guano and fermented plant juice significantly produced 11.33 ±0.57SE more flower per plant gathered after 45 days from transplanting. Moreover, these plants had the highest number of fruits 9.39 ±0.51SE at first harvest. Furthermore, yield parameters of cherry tomato plants treated with combined bat guano and fermented seaweed is doubled 509±0.20SE g total yield compared to the recommended rate of inorganic fertilizer (229±0.68). Based on the study's findings, the combined bat guano and fermented seaweed seem to promote growth at 55.06±3.81SE cm tall compared to the recommended rate fertilizer 39.61±3.6 SE cm. Furthermore, the combined bat guano and fermented seaweed improved the yield of cherry tomato at 509±0.20SEg two times heavier compared to the recommended rate of inorganic fertilizer 229±0.68SE g. Thus, 500kg/ha of bat guano and 500L/ha of fermented seaweed is recommended for growers of cherry tomatoes. Keywords: cherry tomato, bat guano, chicken dung, fermented seaweed, fermented plant juice Introduction Cherry tomato (Solanum lycopersicum L.) is among the world’s major vegetable crop and a good source of nutritive value. It is rich in vitamins specifically vitamin C and other minerals like phosphorus, iron, and calcium (Bhowmik et al., 2012) [6] . Consumers demand and competition imposed by the market have the provision of a high standard of nutritional value of cherry tomatoes. (Rahul et al., 2018) [22] . Inorganic fertilizer is usually immediately and fast containing all necessary nutrients that are ready for plants (Roba, 2018) [23] . But, in recent years consumption of fertilizer exponentially increased throughout the world, results from serious environmental problems. Fertilization may affect the soil and plant system. Plants consume the fertilizer throughout the soil, they can penetrate the food chain. Then, fertilization leads to soil acidity and water contamination (Savci, 2012) [24] . Though synthetic fertilizers are most frequently applied, organic forms such as bat guano, compost, livestock manure, etc. are broadly used throughout the world (Sothearen et al., 2014). Compared to inorganic fertilizers organic fertilizers have more benefits in the long run (Roba, 2018) [23] . Developing nations used organic fertilizer to avoid environmental pollution by doses of synthetic in the soil (Thirumaran et al., 2009) [30] . Bat Guano carried essential nutrients macro and microelements (Misra et al., 2019) [17] . Also, chicken manure carried excellent fertilizer and released nutrients uptake after mineralize in the soil (Masarirambi et al., 2012) [16] . Regarding the expansion source of manures, seaweed fertilizers are useful in enriching the soil and achieving higher production. Compared to commercial seaweed organic fermented seaweed extract have a beneficial effect to the plant height (Pascual et al., 2020) [21] . Moreover, applying fermented plant juice (FPJ) to vegetable
