Abstract

Physical damage to the fruit affects the quality of Crude Palm Oil (CPO) of palm oil. Gibberellin (GA3) is known as a growth hormone that is able to extend cells and is widely usedin maintaining the shelf life of several types of fruits. This study aims to study the effect of gibberellin dosage, the effect of gibberellin application on the physical quality of oil palm freshfruit bunches. The research was carried out at the North Julok Rayeuk Garden, PT. Perkebunan Nusantara I. The research period was 10 days, in March 2021. This study used a non-factorial Randomized Block Design (RAK) method and 6 replications with a total of 2 samples and a total sample of 48 samples. Parameter testing is compiled on a list of variances and statistical analysis is carried out which tests the average difference with Analysis of Variance (ANOVA) then further tests are carried out using Duncan's Multiple Range Test (DMRT) at 5% level. The results showed that the treatment dose of Gibberellin G1 (15 ml/L water) had a significant effect on reducing fruit loss and had no significant effecton the value of freefatty acids. Keywords: Elaeis guineensis Jacq,Gibberellins(GA3),physical quality

Abstract

This study was conducted to determine the effect of the application of liquid organic fertilizer in cow urine on the vegetative growth of oil palm seedlings in early nurseries. This research was conducted in the experimental garden of ITSI Medan. This research was conducted for 3 months. Starting from August 2021–October 2021. This study used a non-factorial Randomized Block Design (RAK) method consisting of 5treatments with 5 replications, so the number of samples was 25 seeds. Parameters observed were plant height, stem diameter, number of leaves, shoot dry weight, root dry weight, shoot wet weight and root wet weight. The data obtained were statistically analyzed by DMRT and ANOVA tests. The results of this study indicate that the application of liquid organic fertilizer cow urine has an effect on the vegetative growth of oil palm seedlings in early nurseries with the best dose of 20 ml cow urine. The standard gave some significant and very significant effects on stem height, stem diameter, number of leaves, but had no effect on wet weight and dry weight. Keywords:urine, pre nursery, poc
