Abstract

Zingiberaceae is well known as gingers family with abundant numbers of spices widely used in Southeast Asia, because of their unique flavors, ornamental and also the medicinal values. The extracts of Zingiberaceae rhizome contain many essentials oils, including terpenes, alcohols, ketones, flavonoids and phytoestrogens that use as medicine. Zingiberaceae grow vigorously in a wide range of habitats ranging from riverine to the limestone area, from lowland to the upper mountain regions. They often grow in shady area but some of the native species are able to tolerate to the sun exposure. The cultivation of this family was developed widely. Gunung Cut Village is one the villages in Aceh Barat Daya district which cultivated four species of this family: Zingiber officinale, Curcuma domestica, Alpina galanga and Kaempferia galanga. They mainly use for medicinal purposes as it can cure many diseases traditionally.

Abstract

The study was aimed to obtain information regarding the early selection method of Limau lime under saline and drought condition including the proper method for seed extraction, observation period in germination testing, and type of germination media. The experiment was conducted from March 2015 to January 2016 at the Laboratory of Seed Science and Technology, Department of Agronomy and Horticulture, Faculty of Agriculture, Bogor Agricultural University. It consisted of four main experiments. The first experiment was the extraction method on Limaulime seed using distilled water, ash from the husk, talcum powder, and HCl 1%. The second experiment was germination testing of lime seed using three media i.e. sand, the combination of sand: soil (1:1) (v:v), and towel tissue. The third experiment has tested the vigor of Limau lime seeds in different saline conditions by using NaCl, i.e. 1500 ppm, 3000 ppm, and 4500 ppm. The fourth experiment, tested the vigor of Limau lime seeds in drought stress condition using PEG 6000, i.e. 0, - 0.75 bar, -1.5 bar, and -2.25 bar. The result of the first experiment showed that the treatments had no significantly different effect on all variables observed except for the seed moisture content. The second experiment revealed that the best germination media was elucidated from sand treatment and sand: soil (1:1) with the first and the second count at 20th and 29th day respectively. The result of the third and four experiment elucidated that the higher concentration of NaCl (Salinity stress condition) or PEG 6000 (drought stress condition), the smaller the germination percentage of Limau Lime’s seeds.

Abstract

Mangosteen (GarciniamangostanaL.) knows as one of the most delicious fruit in the word, it’s call as “Queen of fruits”. The problems in mangosteen culture are low productivity and low fruit quality due to less developed technical culture, especially on fertilizer. There is a little information available on mangosteen fertilizer recommendation standards based on scientific experiment.Phosphor fertilizer increased growth especially in the generative stage of mangosteen. Phosphor increases the number of flowers and fruits set. It also decreases the number of flowers and fruits drop, with a linear response. It indicates mangosteen trees absorb phosphor to increase the vegetative growth and support production. Fertilizers increase phosphor concentrations in leaf tissues. Leaf tissues analyses showed the status of phosphor status, This status has a correlation to the yield. The higher the nutrients concentration in the leaf tissues, the higher the mangosteens yield in the next harvest

Abstract

The availability of nutrients in plants depends on the ability of plants to absorb nutrients from the soil. One of the processes absorbed by plants is by the presence of the transpiration process.  Good transpiration will provide enough nutrients for plants which increase the productivity and quality of mangosteen. One of the quality standards of mangosteen fruit for export quality is the free from yellow sap contamination. It can be possible that transpiration can improve the quality of mangosteen fruit by applying fertilization. In this study Ca fertilization was carried out on mangosteen seeds, where this study aims to investigate the effectiveness of Ca uptake by mangosteen plants with the level of water loss by transpiration. This research was conducted in November 2016-March 2017 at the Leuwikopo Experimental Garden, Bogor Agricultural University. Morphological observations were carried out in its Experimental Garden and the Postharvest Laboratory whileanalysis of calcium content of plant tissue was done at the Department of Agronomy and Horticulture, Bogor Agricultural University. Data obtained then were analyzed using ANOVA test. If the results were significant, Duncan Multiple Range Test (DMRT) was then tested at 0.05 probability level. The results revealed that the transpiration rate of mangosteen plants from several treatments showed a significant difference, the transpiration rate was higher, especially in fertilized plants. The size of the 12th leaf, plants treated with fertilizer have a larger size than the treatment without fertilization. Fertilizing and providing enough water can maintain the growth of the plants.

Abstract

Pamelo (Citrus maxima (Burm.) Merr) is one type of orange that is prospectively cultivated in Indonesia. Pamelo in Indonesia is very diverse, as the skin of the fruit is green to red, some are  with seed and seedless. Pamelo plants have diverse leaves, both in shape, size, lamina and thickness. The various leaf shapes between plants which show below the genetic resources of pamelo plants are numerous and varied. Information about pamelo aceh plants, especially about the character of leaves is still very limited. This information can be used to determine the characteristics of pamelo aceh so that later it will be very useful in classifying and grouping plants. The purpose of this study was to determine the character of the Pamelo Giri Matang leaf in Aceh, Indonesia. The study aims to see the level of diversity of pamelo in the village of Pante Lhong. The study was conducted in the village of Pante Lhong, Peusangan District, Bireuen,  District, Aceh, Indonesia and at the Laboratory of Agroecotechnology, Faculty of Agriculture, Universitas Malikussaleh, from September to November 2017. The sample plants used were 15, aged between 10 and 25 years. The research was conducted using descriptive method with sampling by purposive sampling method. Observations were carried out quantitatively and qualitatively based on Descriptors for Citrus (PGRI).

Abstract

The quality of seed needs to be considered in carrot seed production to maintain its productivity. The research aims to find out the response of stecklings age and plant spacing on carrot seed quality and production. This research was held on July 2018 – April 2019 in Berastagi field trial (1340 m MSL). The experiment used Randomized Complete Block Design (RCBD) with two factors, i.e., stecklings age (2 and 3 months) and plant spacing (25, 50, 75, and 100 cm), replicated four times (32 experiment units), 10 plants from each experiment units were taken as samples. The result showed that stecklings age and plant spacing were affected to plant vegetative and generative stages. The combination of 2-month stecklings and 50 cm plant spacing increased the number of secondary umble, if compared to cultivation, which was generally used by the farmer (3-month stecklings and 25 cm plant spacing). The best quality of carrot seed was obtained from the combination of 3-month stecklings and 50 cm plant spacing.
