Effect Induction Bio Hormone on Production and Content of Nutritional Substances on Tomato Fruit Variety Cherry Small Fry and Cherry Japan
Food quality could be determined based on the criteria of food security, nutrition content, and trade standard on foodstuffs to food and beverages (Anonymous, 1996). At the stage of production or tomato cultivation system, the treatment accorded aims to increase the quantity and quality of tomatoes such as increased shelf life, organoleptic quality, and nutritional content. The content of the most prominent nutrient in tomatoes are vitamin C and carotene as forming pro-vitamin A. The content of vitamin C and carotene in tomatoes was useful to help the healing process sprue disease and night blindness. This type of research is experimentally using factorial completely randomized design. Factor I: Varieties of tomatoes which consists of two varieties, namely Cherry Small Fry (CSF) and Cherry Japan (CJ) and the second factor is the addition bio hormone i.e. non-induction bio hormone (B0) and induction bio hormone (B1). Each treatment was repeated 3 times so that overall there are 12 experimental units. Duncan test showed the CJ tomato induced growth hormone has the highest production with the average amount of 2449.10 grams
