Abstract

ABSTRACTThe farmers involved in Organic farming have many problems, particularly in agriculture, in terms of the provisions dealing with the cultivation of organic food which refers to SNI 6729 in 2010 in which the seed used must come from organic farming itself. In addition to the seed, organic farming requires a suitable varieties for organic conditions, suspected nutrient deficiencies, while special varieties are produced  to organic land  is  not  yet  available.  Research  done “The Effect  of differences seed origin in organic and conventional farming on the physiological and yield organic rice of local cultivars (Mentik Wangi Susu) and superior (IR-64)". The research conducted at greenhouse K.P.   Tridharma Faculty of Agriculture. University of Gadjah Mada, Yogyakarta from March to August 2012. The research aimed (1) to  study the effect of seed to the physiological properties, and yield of organic rice on local varieties and superior (2) to determining a good seed for rice varieties organically grown. Research design by randomized block consist two factors with 5 replications, the first factor is the cultivar i.e. local cultivars (Mentik Wangi Susu (M)) and superior cultivars (IR 64 (I)), the second is the seed used i.e. the seeds of organic farming (O) and seeds of conventional (K).  Data  were  analyzed,  if  there  is  a  significant  difference  continued  with Duncant multiple range test at 5% level. The results showed that there was no differences between organic and  conventional   seeds to the physiological properties and yield of organic rice on local cultivars (Mentik Wangi Susu) and superior (IR 64). Local cultivars (Mentik Wangi Susu) has higher grain yield per hill than superior (IR-64).Key  words   :   organic   rice,   local   cultivar,   superior   cultivar,   physiological properties, yield

Abstract

ABSTRACTMerah Delimais considered as superior native variety of water apple in Demak. The fruitis wellknown as the high quality water apple  in theregions. Suitable environment of climate,topography and soil physic chemical properties in Demak make it possible for the fruit to produce more than twice per year with attractive physical appearance of the fruit as redand shiny color, large, sweet, crispy and high economic value. However, researches of Merah Delima water apple were still limited compared to other fruit superior commodities. Therefore, the survey as assessment method of water apple was conducted to identify and study the differences of cultivation, growth and production of the fruits which were cultivated in dryland and paddy fields as specific conditions of Demak regency. The assessmentseries included pre-survey in October 2011 – January 2012 and plant’s observation in March –June 2012 which was a peak season for the fruits. The site locations were chosen purposively ,i.e. in Wonosalam, Demak and Bonang Sub Districts. Inthatcase, water apple tree’s population differences were being the criteria of sites selection. Inpresurvey, as many as 50 farmers were interviewed as respondents with the proportion of consecutive 28 : 14 : and 8 farmers for each Sub District. The plant’s observation included 54 trees which were chosen purposively. ‘Nested design’ was used (3 subdistrict x 2 land types x 3 plants). Basically the cultivation results were compared to Water Apple Standard Operating Procedures (SOP) issued by Demak Agriculture Services. Parameters observed in the survey involved physical and chemical properties of soil, microclimate, growth, production and quality of water apple. The results showed that water apple cultivation applied statuses in dry and paddy field were only in low and medium, based on Water Apple Standard Operating Procedures (SOP). Infact, there were significant interaction effect between land types and cultivation applied as well as between the land types and cultivation applied in Merah Delima Water Apple production. Water Apple cultivation in surjan system or integrated with fish – farming system were less suitable since most of the time the roots were under anaerobic condition. Water apple cultivationis more suitable in flat land within termittent irrigation system since soil moisture was not relatively high. In Grumosol soi ltype, available soil moisture is considered as one of soil physical properties that has negative significant effect for Merah Delima water apple production, both in dry land and paddy field. In that case, the higher available soil moisture the lower water apple Merah Delima production.Key words: Merah Delima Water apple, cultivation, dry land, paddy field, Demak SubDistrict

Abstract

ABSTRACTSapodilla (Manilkara zapota (L.) van Royen) is a perishable fruit that exhibits rapid deterioration after harvesting. Low temperature storage has been extensively used to extend the storage life of many fresh commodities, however it is still rarely used for sapodilla. UV-C radiation has been studied for its capability to inhibit fruit ripening and senescence, and hence prolonging the period of fruit salability. This UV-C radiation might be a pre treatment for sapodilla before storage at low temperature. The objective of this research was to extend the storage life of sapodilla fruits by retarding ripening process through UV-C radiation and low temperature storage. Sapodilla fruits were exposed to four levels of UV-C exposure time i.e. 0 (no radiation), 5, 10, and 15 minutes, then stored at room temperature (27,13–28,11oC) and low temperature (16,70–18,13oC). Observations were taken on fruit respiration and ripening, and other related variables. The results showed that there was no interaction between UV-C radiation and storage temperature. The UV-C radiation did not significantly inhibit fruit ripening, thus did not inhibit the fruit senescence and deterioration. Keeping the fruit at low temperature inhibit fruit ripening and prolong its shelf life 6 days longer than those stored at room temperature. Key words : Sapodilla, UV-C radiation, low temperature storage, ripening, deterioration.

Abstract

INTISARIBiji  bawang  merah  sebagai  bahan  tanam  memiliki  posisi   strategis beberapa tahun terakhir. Meskipun demikian, kemampuan berbunga tanaman bawang merah cukup terbatas khususnya pada penanaman di dataran rendah. Di dataran  rendah,  jumlah  tangkai  bunga  yang  dihasilkan  per  individu  tanaman sangat terbatas. Beberapa hasil penelitian sebelumnya memberikan informasi bahwa perlakuan vernalisasi mampu meningkatkan pembentukan bunga pada tanaman bawang merah, khususnya pada penanaman di dataran tinggi. Pada penanaman bawang merah di dataran rendah, informasi mengenai pengaruh perlakuan vernasilasi terhadap kemampuan berbunga hingga saat ini belum ada. Oleh karena itu, penelitian terkait hal tersebut cukup penting untuk dilakukan. Tujuan penelitian adalah 1) mengidentifikasi pengaruh lama vernalisasi terhadap pertumbuhan, pembungaan serta hasil umbi dan biji bawang merah dan 2) menentukan lama vernalisasi yang optimum untuk meningkatkan pertumbuhan, pembungaan serta hasil umbi dan biji bawang merah.  Penelitian dilaksanakan di Kebun Tridharma Fakultas Pertanian UGM, Banguntapan, Bantul, Yogyakarta dari bulan Oktober 2011 – Januari 2012. Percobaan disusun dalam rancangan acak kelompok  lengkap  faktorial  dengan  3  blok  sebagai  ulangan.  Faktor  pertama adalah varietas yaitu: Katumi, Biru, Bima dan Tiron. Faktor kedua adalah lama vernalisasi yaitu tanpa vernalisasi, vernalisasi selama 4 minggu, 5 minggu, dan 6 minggu. Pengamatan dilakukan terhadap tinggi tanaman, jumlah daun, jumlah anakan, jumlah umbi, diameter umbi, berat segar, dan berat kering jemur umbi. Analisis pertumbuhan meliputi indeks luas daun, laju asimilasi bersih, laju pertumbuhan tanaman, dan indeks panen. Hasil penelitian memberikan informasi bahwa lama vernalisasi yang optimal untuk peningkatan berat segar umbi varietas Bima adalah 12-13 hari, dengan indikasi peningkatan berat segar umbi hingga mencapai 14,47 g. Berat kering umbi terbaik dihasilkan oleh varietas Bima (6,00 g) dengan lama vernalisasi 13-14 hari. Pembungaan tidak terjadi pada semua perlakuan  yang diuji sehingga dapat disimpulkan bahwa perlakuan vernalisasi tidak mampu menginduksi pembungaan pada tanaman bawang merah yang ditanam di dataran rendah yang dikarenakan faktor lingkungan (suhu, angin) rata- rata cukup tinggi dan panjang penyinaran yang rendah pada saat penelitian berlangsung.Kata kunci : bawang merah, varietas, vernalisasi, pembungaan.
