Abstract

Urea fertilizer usage in farmers is mostly applied at a higher dose than the standard dose of recommendation. The excessive urea fertilizer usage decreased the plant productivity and quality, also polluting the soil. The experiment aimed to observe the growth, yield, and quality response of rice in low N supplements. The experimental design used a factorial randomized complete block design, i.e., urea doses (0%, 40%, 100% 250 kg ha-1) and rice varieties (Way Apo Buru and Inpari 33). The traits observed were plant height (cm), number of tillers, number of leaves, chlorophyll fluorescence (unit), grain content (%), number of panicles, content of dissolved protein (mg g-1), ascorbic acid (mg g-1), reducing sugar (mg g-1). The results showed that a reduction of 40% urea produced the same higher number of tillers compared to the standard dose (250 kg ha-1). The standard dose of urea resulted in the highest ascorbic acid content, value of chlorophyll fluorescence, and number of panicles. Inpari 33 produced higher plant height and grain content meanwhile Way Apo Buru produced a higher number of leaves. The reduction of 40% urea in Inpari 33 resulted in the highest dissolved protein content. Inpari 33 produced the lowest reducing sugar and could be used as an alternative food for diabetics. Keywords: chlorophyll content, dissolved protein, reducing sugar, vitamin C

Abstract

Tanaman ubi kayu (Manihot Esculenta) merupakan komoditas yang diprioritaskan serta mudah untuk dibudidayakan. Perakitan tanaman ubi kayu memiliki kesulitan dikembangkan secara generatif sehingga dibutuhkan pendekatan kultur jaringan melalui induksi Friable Embryogenic Callus. Beberapa kendala dalam menghasilkan kalus yang embriogenik yaitu genotip serta eksplorasi dari metode dan protokol induksi FEC dari beberapa varietas ubi kayu masih terbatas. Penelitian dilakukan dengan beberapa tahapan yaitu induksi FEC pada media GD dengan perlakuan kultivar yang berbeda yaitu Kaspro (V1), Ketan (V2), Kuning (V3) pada media GD, dilanjutkan dengan proliferasi pada kultur suspensi dengan perlakuan jenis auksin yaitu picloram 12 mg.L-1 (P1), 20 mg.L-1 (P1), dan 2,4-D 12 mg.L-1 (P3) dan perbedaan kultivar. Hasil penelitian yang diperoleh yaitu respon kalus dari kultivar lokal menunjukkan rerata frekuensi dan skor FEC tertinggi terdapat pada Kultivar Kaspro sebesar 51,26% dan skor 4 sebagai kategori kemampuan membentuk FEC tinggi. Pertambahan berat segar tertinggi terdapat pada perlakuan P1 yaitu 1,19 gram serta perlakuan V2P1 yaitu 0,64 gram. Volume suspensi tertinggi terdapat pada perlakuan V1P2 serta viabilitas sel tertinggi terdapat pada perlakuan V3P2.TRANSLATE with x EnglishArabicHebrewPolishBulgarianHindiPortugueseCatalanHmong DawRomanianChinese SimplifiedHungarianRussianChinese TraditionalIndonesianSlovakCzechItalianSlovenianDanishJapaneseSpanishDutchKlingonSwedishEnglishKoreanThaiEstonianLatvianTurkishFinnishLithuanianUkrainianFrenchMalayUrduGermanMalteseVietnameseGreekNorwegianWelshHaitian CreolePersian //  TRANSLATE with COPY THE URL BELOW Back EMBED THE SNIPPET BELOW IN YOUR SITE Enable collaborative features and customize widget: Bing Webmaster PortalBack//
