Yield and quality responses of tomato plants (Solanum lycopersicum L.) to natural growth regulators

Abstract

Abstract Tomato are horticultural commodities that had been widely consumed by the people of Indonesia, but their production is still fluctuating. Tomato commodities have increased in demand because they can be used in various preparations with nutritional content that is good for health. The lack of production compared to the demand for tomato commodities required steps to increase production, one of which is by providing a booster in the form of a natural growth regulator. This study used a Split Plot Design (2x5) with a basic design of Randomized Block Design. The main plot was tomato variety consisting of two types, namely Fortuna and Servo F1. The subplots were natural growth regulators consisting of five types, Water, GA3 100 ppm, Sweet Corn Extract equivalent to 100 ppm GA3, Shallot Extract equivalent to 100 ppm, and Moringa Leaf Extract equivalent to 100 ppm GA3. The results showed that the treatment of different plant varieties affected the parameters of the number of flowers per plant 5 weeks after planting, and the number of fruits per plant. The interaction between natural growth regulators and varieties affected the number of flowers per plant at 8 weeks after planting and Brix.
