Shallots are vegetable commodities that have high economic value, as a fulfillment of national consumption, farmers' sources of income, as well as their potential as foreign exchange earners. One way to increase the production of shallots is to develop a number of high-altitude shallots as well as to adjust the spacing that is suitable in the lowlands. This study aims to determine the growth and yield of some highland shallots due to different spacing in the lowlands. This research was conducted at Experiment Garden 2 East Sector and Horticulture Laboratory Faculty of Agriculture, Syiah University Kuala, Darussalam, Banda Aceh from April to June 2018. This study used a Randomized Block Design 4 x 3 factorial pattern with 3 replications. Factors studied were red onion varieties consisting of 4 levels namely Local Gayo, Tajuk, Batu Ijo, and Brebes spacing consisting of three levels, namely 20 cm x 15 cm, 20 cm x 20 cm, and 20 cm x 25 cm. The data obtained were analyzed using F test, followed by BNJ test at the level of 5%. The results showed that varieties had a very significant effect on the growth and yield of onion plants on all parameters observed. The treatment of plant spacing has a very significant effect on plant height at the age of 15, 30, and 45 day after planting, diameter of tubers, weight of wet seedlings, wet weight of tubers, dry weight and weight of tubers. There is a very real interaction between plant spacing with varieties on wet-weighted, wet weight of tubers, dry-weighted weight and dry weight of tubers.

Dari hasil pengujian diperoleh nomor<br />yang menghasilkan rata-rata bobot rimpang tertinggi yaitu V4 (53,58<br />g/rumpun atau setara dengan 10,7 ton/ha), rata-rata kadar minyak atsiri<br />tertinggi (6,64%) dan beradaptasi secara spesifik pada lingkungan tumbuh<br />yang sama dengan lokasi penanaman di Cijeruk, Sumedang dan Suka-<br />mulya. Sedangkan V2 dengan nilai diameter rimpang terbesar (2,089 cm),<br />stabil di 4 lokasi pengujian, responsif terhadap pemupukan, serta V3<br />dengan rata-rata produksi rimpang 51,98 g/rumpun atau setara dengan 10,4<br />ton/ha, beradaptasi secara spesifik pada lingkungan tumbuh yang sama<br />dengan lokasi penanaman kencur di Cileungsi, Cijeruk dan lokasi asalnya<br />di Sumedang.<br />Kata kunci : Kencur, Kaempferia galanga L., varietas unggul, stabilitas<br />hasil, spesifik lokasi, Jawa Barat<br />ABSTRACT<br />Stability of five promissing Galanga lines production<br />Breeding of Galanga was focused on the improvement of rhizome<br />yield and quality based on the Indonesian Materia Medica Standard, to<br />increase farmers’ income. Based on the selection on rhizome yield and<br />quality, 5 accession numbers were selected as promising lines for their<br />high rhizome yield (&gt;40 g/tiller) and essential oil contents (&gt; 1.5%), e.g.<br />V1, V2, V3, V4 and V5. All numbers were subjected to multilocation tests<br />at 5 locations, e.g. Cileungsi (80 m asl) and Cijeruk (650 m asl) (Bogor),<br />Subang (80 m asl), Sumedang (550 m asl) and Sukamulya (350 m asl)<br />(Sukabumi), for 2 planting-seasons (2002/2003 and 2003/2004). Experi-<br />ments were arranged in a randomized-block design, with 6 replications,<br />plant spacing 20 cm x 20 cm, plot size of 4 x 1 m2, and population 100<br />plants/plot. The research results showed that the highest average of<br />rhizome yield was performed by V4 (53.58 g/tiller, equal to 10.7 t/ha),<br />with essential oil content 6.64% and specifically adaptable to the same<br />agro-climate as the environment conditions at Cijeruk (Bogor), Sumedang<br />and Sukamulya (Sukabumi). Meanwhile, V2 with the highest diameter of<br />rhizome (2,089 cm), stable at 4 out of 5 locations and responsive to<br />fertilizer application. On the other hand, V3 with the average of rhizome<br />yield 51.98 g/tiller, equal to 10.4 t/ha, specifically adaptable to the agro-<br />climate similar to the environment conditions at Cileungsi, Cijeruk<br />(Bogor) and its native, Sumedang.<br />Key words: Kaempferia galanga L., superior variety, yield stability,<br />specific location, West Java

Dayak shallot has various phytochemical compounds that useful for health; people use it as medicinal plants. The technique of cultivating plants has not been informed completely. Hence, the research needs to be conducted to understand the competitiveness of weeds and the best planting space for optimal production. The research objectives are to obtain the effect of weed control and plant spacing for Dayak shallot growth and development. This research was used <em>randomized block design</em> two factors. The first factor is plant spacing and the second factor is weed control. There are four combinations of treatments between planting space and weed control. The treatment combinations used are: (1) Plant spacing of 15 cm x 15 cm with weed control; (2) Plant spacing of 15 cm x 15 cm without weed control; (3) Plant spacing of 30 cm x 30 cm with weed control; and (4) Plant spacing of 30 cm x 30 cm without weed control. Each treatment combination was repeated three times. The results showed that a combination of plant spacing and weed control was affected the percentage of flowering, the number of flowers on 4 and 6 days after planting, and the dry weight of Dayak shallot. The components of plant growth of Dayak shallot (plant height, number of leaves, root length, leaf biomass, root biomass, and total flavonoid content) was not affected by the combination of treatments. The dominant weed is <em>Borreria latifolia,</em> with SDR 30.623%.
