Abstract

Ginger (Zingiber officinale Rosc.) is one of the spices and medicinal plants which has many benefits and usefulness. Currently ginger production in Indonesia is still very low, du e to limited sources of genes possessed by plant breeders (narrow genetic stock), therefore it is  necessary to  obtain new  genetic diversity. The  purpose of  this  study was  to  conduct exploration activities to collect local ginger germplasm in Southeast Sulawesi to get information in the form of (a) genetic diversity of accessions, (b) determination that can be used to identify germplasm genetic diversity of ginger of Southeast Sulawesi, (c) description of the collected ginger types, for the benefit of ginger crop improvement through breeding programs. This study began with exploration activities, then planting accessions for collection and conservation which will be utilized in various ginger breeding programs. The results of exploration obtained as many as 18 accessions from Kendari, Konawe, Bombana, Muna and Buton regencies. Results of the collection of some areas of Southeast Sulawesi showed that ginger genetic diversity was quite high, seen from the morphological appearances of the rhizome.  Based on the size, shape and color of the rhizome, the ginger accessions of Southeast Sulawesi can be classified into three major groups, i.e. large white/yellow ginger, small white/yellow ginger, and red ginger. White ginger was large and more attractive than red ginger, but less spicy aroma due to its low essential oil content, and less disease resistant, but high productivity. Keywords: ginger, Zingiber officinale, genetic diversity

Abstract

Biodiversity is high value genetic resources required for the good of human being. Globally, biodiversity has been degraded into a danger level.   Identification of problems, alternative solutions to protect, to conserve, and to utilize the biodiversity is a primary priority. The utilization of local rice cultivars, as a source of germplasm for rice breeding programs must get special attentions to protect the germplasm from vanishing. Biotechnology or genetic engineering technology provides an alternative way and a short cut in manipulating and producing improved plant varieties.  Different kinds of methods can be used to genetically engineer plant species. Since 1980s and ever since, many achievements and improvements have been made by scientists around the world in the area of genetic engineering, including genetic improvement of rice crops.   As an example, scientists have engineered transgenic rice crops that contain pro-vitamin A in the endosperm.  Pro-vitamin A is a substance that does not naturally occur in rice, but is urgently required to prefend human’s eye blindness. Another example, recently a group of scientist has developed super- rice strain that defies triple whammy of stresses (drought, salty-soils, and lack of fertilizer) simultaneously. Keywords: Biodiversity, biotechnology, genetic improvement, and local rice cultivars

Abstract

The aim of this research was to know the effect of urea fertilizer on growth and yield  of  mustard  plant.  This  research  was  carried  out  at  the  Experimental  farm  of Agriculture Faculty, Haluoleo University, from October to November 2012. This research was carried out using completely randomized block design, that consisted of 6 treatments namely: without Urea fertilizer (U0), 25 kg ha-1 equals to 1.6 g plot1 of urea fertilizer (U25), 50 kg ha-1 equals to 3,2 g plot-1  of urea fertilizer (U50), 75 kg ha-1equals to 4,8 g plot-1of urea fertilizer (U75), 100 kg ha-1 equals to 6,4 g plot-1 of urea fertilizer (U100),125 kg ha-1 equals to 8 g plot-1 of urea fertilizer (U125) . Each treatment was repeated 3 times which resulted in 18 experiment units. The experiment data were analyzed using analysis of variance method and then followed by Honest Significantly Difference Test. The result of the research showed that the application of various dosages of urea fertilizer has an effect on the growth and yield of mustard plant. The application of urea fertilizer to mustard plant effected plant height, leaf area at the age of 21 and 28 days after planting, dry weight of root, dry weight of leaves and relative growth rate. However, the application of urea fertilizer has no effect on the number of leaves, leaf area at the age of 14 days after planting, leaf fresh weight, and the root fresh weight of mustard plant. An increase in the dosages of Urea fertilizer was followed by an increase in the growth and production of mustard plant. 125 kg ha-1 urea fertilizer increased growth and production of mustard plant a lot higher compared to other of urea fertilizer with a production yield of 10 ton ha-1. Keywords: mustard plant, urea
