Abstract

This study aims to determine the effect of the concentration of ultra gene liquid biofertilizers and crowns compound NPK and to find out whether there is any interaction between the both of it on the growth of oil palm seedlings.This research was carried out at the main nursery land of Nusantara I Plantation Limited Company (PTPN I) Kebun Baru, Langsa City, Aceh Province from June to September 2017. This study used factorial randomized block design with 16 treatments repeated 3 times. This study consisted of two factors, namely the dose of ultra gene liquid biofertilizer 0.100, 200 and 300 ml and the dose of crowns compound NPK fertilizer 0,5,10 and 15 g. The results showed that the dose of Ultra Gen liquid biofertilizer significantly affected the stem diameter, leaf number and leaf area in almost all MSP and significantly affected the leaf area of 6 MSP. The dose of Ultra Gen liquid biofertilizer treatment has a very significant effect on the growth of oil palm seedlings, which is indicated by the parameters of the increase in stem diameter, number of leaves and leaf area, and only a significant effect on leaf area 6 weeks after observation. The dose of 200 ml of the Ultra Gen factor shows better growth than other doses. There is a real interaction on seedling growth as indicated by the parameters of the number of seedlings. The highest number of seed leaves was shown by the treatment of 100 ml / polybag ultra gen with NPK 5g/polybag (U1N1), and 200 ml / polybag with no NPK fertilization (U2N0), although not significantly different from the U0N0 and U3N3 treatment combinations, but significantly different with the combination of other treatments. Keywords: crowns NPK, oil palm seeds, ultra gene liquid biofertilizers

Abstract

The diversity of insects, both pests and natural enemies in each place differently is influenced by environmental factors and technical culture of cultivation. This study aims to determine the diversity of pests and natural enemies in nutmeg plants in South Aceh. Insect sampling was carried out at nutmeg plantations in South Aceh, followed by identification in the Faculty of Agriculture laboratory, Teuku Umar University. Methods of data collection using purposive sampling, using light traps, pit fall traps, yellow traps. The Parameters of this study are number of individuals, families, and insect diversity obtained. The results showed that the abundance of pests and natural enemies in Meukek was higher compared to Samadua. The Shannon-Wiener index shows a variety of pests in Meukek high (H'=3.029) and moderate in Samadua (H'=2,788). While the diversity of natural enemies in both Meukek and Samadua is relatively low, namely H'= 1.230 and H' = 1.049. Planting patterns and crop management affect the abundance and diversity of both pests and natural enemies in both locations. Plantations in Meukek tend to be heterogeneous which are planted with a variety of plantation crops (polyculture) while nutmeg plants in the same two are relatively homogeneous (monoculture of nutmeg). Keywords: diversity, pests, parasitoids, predators, nutmeg

Abstract

Seeds are mature ovules. One or more of the ovaries formed in the legume, but never more than one seed formed in the ovaries of monocots. Each ripe seed always consists of at least two parts, namely: (1) Embryo, (2) Seed coat (Seed coat or testa). Embryo is formed or derived from fertilized eggs (zygote) by undergoing cell division in the embryo sac. Seed coat is formed from the integument (one or more) of the ovules. In legumes generally there are two layers of seed coat. Every very young and growing seed always consists of three parts: (1) Embryo, (2) seed coat, (3) Endosperm. Endosperm is a storage food storage network which is absorbed by the embryo before or during seed germination and is always present in very young seeds. Polyembryonics is the presence of more than one embryo in one seed, but these embryos do not always mature or mature, remain undeveloped or degenerate. The purpose of this research is to study the germination of one seed that has more than one embryo and to determine the growth of seedlings from polyembryonic seeds. The results showed that the highest plant growth (plant height, number of leaves, fresh weight and dry weight of orange seeds) was found in orange seeds that had 1 embryo compared to orange seeds which had 2 and 3 embryos. Seed germination and growth is strongly influenced by the amount of food reserves stored in seeds (Magagula and Ossom 2011 in Hasnah M, 2013). Keywords: Citrus Seed, Polyembrioni, Seed Viability

Abstract

Abstract Histosol is an organic soil with a high acidity value (pH 4.5) and low levels of nutrients N, P, and K that is effects to plant growth and yield. This study aims to examine the effect of dolomite and NPK fertilization on the growth and yield of Okra (Abelmoschus esculentus L.) on Histosol soil. This research was conducted in the Experimental Garden of the Faculty of Agriculture, Teuku Umar University, West Aceh. This study used a factorial 4 x 4 randomized block design (RBD) with 3 replications. The factors studied include: 1) Dolomite factor (D) consists of 4 levels, namely: D0= without liming, D1= 22.5 grams/polybag, D2= 45 grams/polybag, D3= 67.5 grams / polybag; 2) NPK fertilizer factor (N) consists of 4 levels, namely: N0= zero NPK fertilizer application, N1= 11.25 gram/polybag, N2 = 18.75 grams/polybag, N3= 26.25 grams/polybag. The results showed that dolomite dose had a very significant effect on plant height, stem diameter and number of leaves of okra plants aged 15, 30, 45 and 60 HST. Very significant effect on the length of the okra fruit aged 73 HST and significant effect on the weight of the fruit age 73 HST, but no significant effect on fruit diameter, number of fruit age and production per hectare (tons) 73 HST. NPK fertilizer has a very significant effect on plant height and stem diameter aged 15, 30, 45 and 60 HST. Very significant effect on fruit length and diameter okra fruit aged 73 HST. Not significant effect on the number of fruits, fruit weight and per hectare production (tons) of okra aged 73 HST. There was no interaction between dolomite and NPK fertilizer from all treatments.Keywords : Histosol, acidity, liming and fertilizing, growth and yield of okra plants

Abstract

Nutmeg (Myristica fragrans Houtt) is a multipurpose plantation commodity crop that almost all parts of the plant have strategic economic value to be cultivated. In Indonesia there are the largest nutmeg commodity centers, including the Maluku islands, North Sulawesi and Aceh. The biggest problem with nutmeg plants is the attack of pests and diseases. One of the most severe diseases in nutmeg is white root mushroom (Rigidoporus lignosus). This study aims to 1) determine the fungus of white root fungus antagonists (Rigodoporus lignosus) from the Aceh nutmeg rhizosphere (Myristica fragrans Houtt), 2) identify the content of antibiotic fungus JAP antagonist compounds in Aceh nutmeg plants. The study was conducted by taking soil samples from nutmeg plants at three nutmeg plantations in South Aceh. The antagonist fungus isolation activity uses a dilution method. Isolation of JAP from infected roots using direct planting method. Furthermore, it is identified macroscopically and microscopically. The antagonist test was carried out using the dual culture method with RAL. From the rhizosphere in the nutmeg area, 5 candidate antagonist isolates were obtained, having high in vitro antagonism ability to the pathogen R. lignosus. Identification results showed that isolates 1, 2 and 3 were Trichoderma spp, and isolates 4 and 5 were Gliocladium virens.
