dc.description.abstract | This study aims to determine the effect of vitamin B1 application, variety
and interaction of vitamin B1 and variety on the growth of cacao seedlings
(Theobroma cacao L). This research was conducted in the Gauze House. Faculty
of Agriculture, Universitas Sumatra Utara Medan, with an altitude of ± 25 meters
above sea level. This research was conducted from July to December 2023. This
study used a factorial randomized group design (RBD) consisting of 2 treatment
factors. The first factor was cocoa plant variety consisting of three levels namely
ICS 60, RCC 70, and Lindak, and the second factor was vitamin B1 application
(concentration of 10 ml/liter) consisting of 4 application method namely control,
soaking seeds, foliar aplication and soaking seed + foliar application. Observed
vanabels were plant height, stem diameter, number of leaves, leaf area, number of
branches. The results showed that vitamin B1 application, variety, interaction
between varicty and vitamin B1 did not significantly affect all observation
variables except vitamin B1 application significantly affected stem diameter at 6
WAP. However, based on several observation variables it is known that seedlings
of Lindak variety which sprayed wilh vitamin B1 (V3B2) had better growth than
other treatment combinations. | en_US |
