Title : Influence of the height of the growing place on the yield and quality of flower seeds on shallot (Allium ascalonicum L.) In yogyakarta province


Yogyakarta Special Region (Daerah Istimewa Yogyakarta/DIY) with its specialty has the potential of a large area, with a diversity of elevations, ranging from highlands to lowlands or land on the coast in the height range of 0-2911 meters above sea level. DIY consists of Kulon Progo Regency, Bantul Regency, Gunung Kidul Regency, Sleman Regency, and Yogyakarta Municipality. The diverse state of agroecosystems can be grouped in coastal land agroecosystem zones, rice fields, lowland dryland, and highland dryland.  The purpose of this study is to find out the influence of place height on the results and quality of shallot seeds. The research was conducted on-farm research in Selopamioro village, Imogiri Subdistrict, Bantul (400-700 HSL); Hargobinangun village, Pakem Subdistrict, Sleman (> 700 HSL); and Gerbosari village, Samigaluh subdistrict, Kulonprogo (< 400 HSL), in April - August 2017. This experiment was conducted with a Randomized of Complete Block Design (RCBD) nested, with a design of one-factor treatment and blocks in the form of villages in one province at that height. Factors used are the altitude of the place consisting of lowlands (<400 mL), medium plains (400–700 HSL), and plateaus (>700 HSL). The observed parameters are microclimate sand, soil ground content and soil chemical fertility, plant physiological activity, and analysis of the results and quality of shallot seeds. The results of this study show that differences in the height of places will affect the differences in microclimate, in the form of air temperature, soil temperature, air humidity, and soil content which will later affect the results of shallot seeds and the quality of growing power of shallot seeds, while other quality variables are influenced by chemical fertility conditions in the soil,  as in the weight of shallot seeds that are affected by the content of Ca and C-organic.


I am Dr. Tria (Tri Martini Patria), a researcher in the field of crop protection from AIAT Yogyakarta, a research institute under the Ministry of Agriculture located in Yogyakarta Province. Graduated from a doctoral program at Universitas Gadjah Mada in 2014. Have experience in conducting research in Food Crops and Horticulture commodities, including releasing varieties of several types of floriculture in Indonesia. Research related to land resources was conducted to find out the potential for the development of agribusiness areas in DIY provinces.
