Abstract

Global climate exchange especially rainfallspurs the growth of oil palm adapt to environmental conditions, so the development of oil palm plantations requires seeds that are able to adapt well in drought conditions.This study aims to determine whether water stress affects the growth of oil palm seedlings and sees the response of the level of resistance of oil palm seeds to drought stress.This research was carried out in the greenhouse garden experiment Medan STIPAP was conducted from January to June 2018. This study used Non-factorial Randomized Block Design (RBD), which consisted of 3 levels, 3 samples and 3 replications. Parameters to be observed were plant height, stem base diameter, leaf number, root wet weight, root dry weight, plant wet weight, plant dry weight, root volume, root length, stomatal density and number of stomata.The results showed that the difference in giving A1 water (100%) was significantly different from A2 (60%) and A3 (20%) on the parameters of oil palm seedling growth especially for the parameters of plant height, root wet weight, root dry weight, plant wet weight, plant dry weight, root volume, and root length while the base diameter of the stem, number of leaves, stomatal density and number of stomata give no significant effect. Drought stress effected to reduce the growth of stem diameter.

Abstract

The cultivation of wheat in Indonesia especially at medium-low altitude faces problems such as high temperatures whicheffect negativelyon the yield. The aims of this research was to obtain informations on performance, genetic variability and heritability of agronomic characters of wheat putative mutant lines on M5 generation. Genotypes evaluated in the study consisted of 98 putative mutant lines of M5 generation and six varieties as checks, namely Dewata, Selayar, Oasis, Rabe, Kasifbey, and Basribey. The research was conducted at Research Station of IOCRI (Indonesian Ornamental Crops Research Institute), Cipanas. Genotypes were arranged in an augmented, randomized block design. Result of the experiment showed that high heritability estimates were observed for plant height (83.03%), tiller number (61.75%), days to flowering (85.41%), days to maturity (67.45%), spike length (70.25%), spikelet number (65.08%), unfilled grain number (71.49%), seed number per spike (75.16%), seed weight per spike (81.69%), and seed weight per plant (74.21%). The estimated genotypic coefficient of variation (GCV) were high for unfilled grain number(26.35%) and seed weight per plant (18.35%). Based on seed weight per plant, 30 best putative mutant lines were selected.Keywords: Augmented design, heritability, Triticum aestivum

Abstract

Root trainer technology can be an alternative for rubber plant nursery that have ease in transportation and distribution. Organic materials which are lightweight, porous, and contain nutrients are considered suitable for root trainer growing media. This research was carried out at Sungei Putih Research Center Greenhouse, Deli Serdang from January - May 2019. The research was arranged based on a Randomized Block Design (RBD) with 4 media combination treatments namely: top soil (P0), empty bunches and manure (P1), empty bunches and rice husks (P2), and empty bunches and solid decanters (P3). The results showed that the planting media did not have a significant effect on plant growth including stem diameter, plant height, and number of leaves, as well as the percentage of successful grafting. The treatment of oil palm empty fruit bunches and solid decanter gave better growth than other organic materials. The availability of empty bunches and solid decanter in North Sumatra is relatively abundant so that it can support rubber nurseries throughout the year.

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

The height of one of the external factors that affect production. Chlorophyll is one of the factors that can affect palm oil production. There are several other factors that affect the productivity of oil palm plants, namely climate, territorial shape, soil conditions, planting material, and cultivation techniques. Altitude (altitude) is one of the outside factors that affect production. Differences in altitude cause differences in productivity so that production data need to be analyzed and compared. Height differences cause differences in productivity so production data need to be analyzed and compared. This research was conducted in the Bah Birung Ulu PTPN IV in April-June 2018. This study aims to determine the effect of altitude in the highlands area the effect of the amount of leaf chlorophyll on the production of oil palm fruit (Elaeis guineensis Jacq.). The method used is descriptive analytic method by processing secondary data (LM 76) and take leaf samples and measure chlorophyll content using chlorophyll meters. The results showed that in the highlands (Kebuna Bah Birung Ulu) had the highest production in 2006, amounting to 22,976 Ton / ha / year. The highest amount of chlorophyll of palm oil was found in the 2005 planting year, which was 80.5 CCI. The largest production of oil palm is in the 2006 planting year of 22,976 Ton / ha / year with 3,148 mm / year of rainfall.

Abstract

The rubber plant (Hevea brasiliensis) comes from Brazil. The first rubber tree grew only in South America. Rubber plantations in Indonesia were introduced in 1864, since Hofland established a rubber plantation company in Tanah Panunukan and Ciasem, West Java. Attacks caused by Pestalotiopsis sp. showed brown spots on rubber leaves and a clear boundary between the spots and the healthy leaves. Infected leaves fall prematurely. Generally, those that are heavily attacked are rubber plants that have produced and are not maintained. The aim of the study was to determine the resistance level of introduced clones (PB 217, PB 260, PB 330, PB 340, RRIC 100, IRR 220 and GT 1) to leaf fall disease, namely Pestalotiopsis sp. The research was conducted at the Plant Protection Laboratory of the Sungai Putih Research Institute, using a non-factorial Completely Randomized Design (CRD). The observation result showed that clones PB 217 and GT 1 had the highest attack intensity after 8 days of inoculation namely 89.96% and 89.96%. The lowest attack intensity was found on clone IRR 220 namely 81.64%.

Abstract

Oil Palm (Elaeis guineensis Jacq.) Is one of the important plantation crops in Indonesia. This plant produces vegetable oils that are important for the food industry and for fuel (biodiesel). Oil palm produces the highest oil unity of area compared to other types of plants with oil potential of around 6-7 tons/ha/year. The research was carried out in the greenhouse of the Plantation Agribusiness Institute of Higher Education (STIPAP). The study period was 6 months from September to March 2018. This study also used a non-factorial randomized block design with 3 times replication, the number of polybags per treatment was 3. Parameter tests were arranged on the variance list and Duncan's Multiple Range Test (DMRT) was tested level of 5%. The results of this study indicate that DyxP DUMPY varieties have good resistance to water stress. Dy×P Dumpy varieties were relatively more adaptable and gave better growth compared to other varieties in the condition of giving 1000 ml of water which was shown in observing the height increase of plants, increasing the number of leaves, increasing the diameter of the stem.
