Abstract

This research was conducted in Medan Marelan District, Medan City, North Sumatra. This research began in April 2024 until July 2024. The aim of this research was to determine the effect of administering several concentrations and methods of application of Paklobutrazol on the growth and production of beet plants. This research used a factorial randomized block design (RAK) consisting of two treatment factors, with the first factor being Paklobutrazol with the symbol (P) consisting of 3 treatment levels, namely: P0 = control, P1 = Paklobutrazol 0.5 grams/plant, P2 = Paclobutrazol 1 gram/plant. The second factor is the application method with the symbol (A) which consists of 2 levels, namely A1 = pour 100 ml of water/plant, A2 = sow. The parameters observed in this research were plant height (cm), number of leaves (strands), wet weight per plant (gr), tuber weight per plant (gr), and sugar content per plant (%). The results of the research showed that Paklobutrazol treatment had a very significant effect on plant height at 6 WAP and 7 WAP, wet weight per plant, tuber weight per plant. The application treatment had a very significant effect only on the tuber weight parameter per plant. The interaction of the two treatments had a very significant effect on plant height at 5 WAP, 6 WAP and 7 WAP, number of leaves at 5 WAP, 6 WAP and 7 WAP, fresh weight of plants, weight of tubers per plant, and sugar content per plant. The best treatment combination was in treatment P1A1 (Paklobutrazol 0.5 grams per plant) and (application method with cocor).

Abstract

This research was conducted in Medan Marelan District, Medan City, North Sumatra Province. They were starting from January to July 2024. Cherry tomatoes (Solanum lycopersicum var. cerasiforme) are one of the vegetables grown by Indonesian farmers. Cherry tomatoes have great economic value and can not only be used as vegetables but also as raw materials for the pharmaceutical, cosmetic, and food industries. This research aimed to determine the effect of giving several concentrations of gibberellin and humic acid PGRs on the growth and yield of cherry tomato plants. This research used a factorial randomized block design (RAK) consisting of two treatment factors, with the first factor being gibberellin with the symbol (G) consisting of 3 treatment levels, namely: G0 = control, G1 = Gibberellin 10 ml/Liter of water, G2 = Gibberellin 20 ml/Liter of water. The second factor is humic acid with the symbol (A) which consists of 4 levels, namely A0 = control, A1 = 1 gr/Liter of water, A2 = 2 gr/Liter of water, A3 = 3 gr/Liter of water. The parameters observed in this study were plant height (cm), stem diameter (mm), number of branches (bb), flowering age (days), leaf color (bwd), number of fruit per plant (fruit), fruit weight per plant (gr ) and fruit weight per plot (gr). The research results showed that gibberellin treatment had a significant effect on flowering time and the number and weight of fruit on cherry tomato plants. Humic acid treatment has a substantial impact on plant height at 4 WAP, 5 WAP, 6 WAP, and 7 WAP, stem diameter at 4 WAP, 5 WAP, 6 WAP, and 7 WAP. The interaction of the two treatments had a very significant effect on stem diameter at 6 WAP and 7 WAP.
