Abstract

ABSTRACT Cherry tomato (Lycopersicum esculentum var. Ruby) is a horticultural commodity that has increased development prospects because of its use in a wide range of people. This study aims to obtain the best interaction between PGR paclobutrazol and types of nitrogen fertilizers on the growth and yield of cherry tomato (Lycopersicum esculentum var. Ruby). This research was conducted in February 2023 - May 2023 in Paciran Village, Paciran District, Lamongan Regency, East Java. The study used a randomized block design (RBD) which consisted of 2 factors, namely the concentration of paclobutrazol and the type of nitrogen fertilizer with 20 combination treatments repeated 3 times. The first factor was Paclobutrazol (P) with 5 treatment levels, namely 0 ppm, 100 ppm, 125 ppm, 150 ppm and 175 ppm. The second factor was the type of nitrogen fertilizer with 4 treatment levels, namely NPK 25 g/plant, Urea 8 g/plant, ZA 17 g/plant and KNO3 28 g/plant. The results showed that the combination treatment of paclobutrazol concentration and type of nitrogen fertilizer had a significant effect on all research parameters. The combination treatment with a concentration of 150 ppm paclobutrazol and a type of nitrogen fertilizer KNO3 28 g/plant showed the best results on the age of flower emergence (22.50 days), the total number of flowers per plant (406 flowers), the number of fruits per bunch (27.17 fruits), total number of fruit per plant (70.01 g), total fruit weight per plant (137.80 g), fruit set (89.17%), and sweetness level (9.20%). Keywords : Paclobutrazol, Nitrogen Fertilizer, Cherry Tomato.
