Abstract

This research was conducted on September 2017 – March 2018, in the greenhouse and laboratory of STIPAP Medan. This study used a factorial randomized block design with three repetitions, with total sample was 27 samples. Parameters observed were plant height, stem base diameter, leaf number, leaf area, root number, root length, root dry weight, shoot dry weight, root volume and number of stomata. The data obtained were analyzed statistically by analysis of variance (ANOVA) with Duncan's advanced test of 5%. The results showed that the di erence in the provision of water in the Main Nursery nursery a ected to the growth of oil palm seedlings significantly a ected plant height, canopy dry weight, leaf chlorophyll and root volume except stem diameter, leaf number, leaf area, number of roots, root length, weight dry root and number of stomata. Oil palm is a plant that has shallow roots (root fibers), so it is easy to experience drought stress. Water availability is one of the main limiting factors for the growth and production of oil palm plants. In the vegetative phase lack of water availability can cause damage to plant tissue, while in the generative phase can reduce the production of oil palm plants.

Abstract

Mucuna bracteata is a type of Leguminosae Cover Crop (LCC) which is widely used in Indonesian plantations. The advantage of Mucuna bracteata is that it grows fast. Based on this, a study was conducted to see the rate of difference in the number of internodes planted which could accelerate the growth and development of Mucuna bracteata. The research was carried out in the practical garden area of ​​the Medan Agricultural College of Agribusiness (STIPAP). The research was conducted from May to June 2020. This study used a non-factorial randomized block design (RBD), which consisted of 1 treatment with 4 levels, namely R0 (1 rolled segment), R1 (2 rolled sections), R2 (3 rolled humps), R3 (4 rolled humps) and with 5 repetitions. The results showed that the treatment of R2, namely 3 bundles of rolled knuckles, gave the best effect on the parameter increase in tendril length, namely 89.66 cm, the increase in the number of tendrils, namely 6.38, the increase in the number of leaves, namely 12.50 strands, the increase in the number of segments, namely 11.32 pieces, and the measurement of the root volume, namely 13.00 ml. The treatment of the number of bunded knots had a significant effect on the parameters of tendril length, number of tendrils, number of leaves, number of internodes, and volume of roots.

Abstract

Physical damage to fruit on oil palm fresh fruit bunches due to harvest and postharvest activities include injuredfruit mesocarp, fruit weight loss, and loss in fruit bunches. One of the postharvest handling that can maintainthe physical quality of the fruit is by giving gibberellins (GA3). This research aims to determine the effect of theconcentration of gibberellins (GA3) whit application time before harvest on the physical quality of postharvestoil palm fresh fruit bunches. The research was conducted at Afdeling VI Garden Cot Girek PT. PerkebunanNusantara I and in the Cot Girek Palm Oil Factory laboratory. The time of the research was conducted in Juneuntil July 2019. The study used a non factorial randomized block design method with 4 treatment levels (0 mg/l,50 mg/l, 100 mg/l, and 150 mg/l) with 3 replications. The administration of gibberellins has a significant effecton fruit loss and fruit weight reduction with the best concentration og gibberellins is 50 ppm but does not havea significant efffect on pH, moisture content, and fruit free fatty acids.
