Abstract

This study aimed to examine the effect of paclobutrazol concentration and side shoots pruning on the growth and yield of cherry tomato plants. This study used a factorial Complete Randomized Design (RAL) with 2 factors and 3 replicates. The first factor was the concentration of paklobutrazol consisted of 4 levels, namely 0 ppm (P0), 75 ppm (P1), 150 ppm (P2), and 225 ppm (P3). The second factor was side shoots pruning consisted of 2 levels, namely without pruning (M1) and with pruning (M2). Parameters observed include plant height, number of leaves, leaf area, chlorophyll and carotenoid content, flowering time, number of fruits, fruit weight, fruit diameter, fruit length, flesh thickness, fresh weight of plant biomass, dry weight of plant biomass, and harvest index. The data were statistically analyzed by analysis of variance (ANOVA), then continued with the 5% Honest Significant Difference (HSD).The results showed that paclobutrazol treatment had a significant effect on plant height parameters, number of leaves, leaf area, flowering time, number of fruits, fruit weight, fruit diameter, fruit length, thickness of fruit flesh, wet weight of plants, dry weight of plants, and harvest index. Pruning treatment has a noticeable effect on the parameters of plant height and number of leaves. The interaction between paklobutrazol concentration treatment and pruning is in the parameter of leaf count.

Abstract

Tomatoes are a popular commodity in Indonesia, with demand increasing every year. The lack of production compared to the demand for tomato commodities requires 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 Group Design. The main plot was Tomato Plant Variety, which consisted of two types, namely Fortuna Variety and Servo F1 Variety. 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 Fortuna tomato variety gave the best results in the parameters of dry weight of biomass per plant and chlorophyll content, while the application of moringa leaf extract gave the best results in the parameter of leaf area.
