Evaluasi Varietas Padi Sawah Pada Display Varietas Unggul Baru (Vub) Di Kabupaten Karawang, Jawa Barat

Abstract

<p>More than 80 high yielding varieties of rice have been released nationally by IAARD to support acceleration of national rice production. Inpari 13 was the one of some new variety that has been released at 2011 and have superior trait i.e early maturity and high yielding. Inpari 13 and some another new variety would disseminated at ICM program at this year. That variety needed to evaluated on Display Area and cultivated by using ICM technology and its compared with old variety as well as Ciherang. This study was to evaluate performance and yield of some new varieties compared old varieties specifically in Dem area. The experiment was conducted in West Java AIAT Dem Area, District Jayakerta, Karawang. The study was done on DS 2011 (Mei 2011-Januari 2012) by using randomized block design with 3 replications. Six varieties were tested i.e Ciherang, St. Bagendit, Inpari Inpari-7, Inpari-10, Silugunggo and Inpari-13. Integrated Crop Manajemen system i.e legowo 2:1, optimal fertilization, and IPM were used at this research. The results showed that there were signifant differences between varieties in all characters except leaf color index. Ciherang has the highest plant height (97,59 cm). Inpari-7 has the highest number of productive tillers and 100 grains weight (25 tillers/clump and 2,8 grams) and the least number of empty grains (7 grains/ panicle). St. Bagendit has the highest number of pithy grain (183 grains/panicle). Silugonggo was the early maturity but it’s resistant to stems brown planthopper (almost had a crop failure). The highest dry grain harvest was owned by Situ Bagendit (8,10 t.ha 1) followed Ciherang (8,08 t.ha-1), Inpari-13 (8,07 t.ha-1), Inpari-7 (7,52 t.ha-1), Inpari-10 (6,71 t.ha-1), and Silugonggo (2,05 t.ha-1).</p>

Correlation and regression models of rice bran to predict chemical composition with organoleptic tests

“…The crude protein value is usually the opposite of the crude fiber value. The coarser a feed ingredient indicates a high protein value and a low crude fiber value [11].…”

“…The higher the crude fiber value of the rice bran, the lower the clumping capacity of the rice or the more crumbly the rice bran is if you hold it. The crumbly nature of rice bran is due to the voluminous nature of the fiber and has a hollow structure so that when held, the rice bran is easily crushed or crumbled [11].…”

Farmers Perception, Attitude, and Satisfaction Level of Soybean High Yielding Varieties in Kebumen Distric, Central Java

“…Badan Penelitian dan Pengembangan Pertanian (Balitbangtan) telah banyak menghasilkan teknologi varietas unggul kedelai yaitu sebanyak 37 varietas dengan keunggulan diantaranya adalah i) potensi hasil tinggi lebih dari 3 t/ha misalnya varietas Detap, Derap, Demas, Dega, Gema, Grobogan dan Biosoy, ii) toleran terhadap cekeman biotik dan abiotik tertentu misalnya tahan naungan lebih dari 50 % pada varietas Denasa, iii) umur panen genjah sehingga dapat disesuaikan dengan pola tanam misalnya varietas Gema dan Denasa, iv) keunggulan mutu hasil sesuai dengan permintaan pasar misal kedelai berbiji besar disukai oleh produsen tempe seperti varietas Grobogan, Anjasmara, Biosoy dan Denasa, sedangkan kedelai berbiji kecil-sedang lebih disukai oleh pengrajin tahu seperti varietas Gema, Dena dan Demas, v) tahan rebah dan tidak mudah pecah polong misalnya varietas Deja, Detap, Derap dan Dega (Balitkabi, 2021;BB Biogen, 2018). Banyaknya varietas unggul tersebut memberikan keleluasaan bagi petani untuk memilih varietas yang sesuai dengan kondisi spesifik lokasi dan pergiliran varietas (Rohaeni & Ishaq, 2016). Namun secara nyata, tingkat sebaran dan adopsi petani terhadap varietas unggul kedelai masih relatif lambat.…”

Effect of Corynebacterium Against Xantomonas Campetric Causes of Bacterial Leaf Blight in the Paddy Plant (Oryza sativa L.) Varieties Inpari 13

“…formal strata, strata of informal perseverance and the strata of mixed seed, varieties of Sarinah, IR-64 and Inpari 13 Potentially adopted and developed in the Wolayah of SPI [3]. The results of dried grain varieties of Situbagendit range from 8.10 tons ha-1, Ciherang 8.08 ton ha-1, Inpari 13 8.07 ton ha-1, Inpari 7 7.52 ton ha-1, Inpari 10 6.7 ton ha-1 [4], Dianawati and Sujitno added that Inpari 13 had a relatively high production of Inpari 4 [5]. Some research results showing the resilience of some rice varieties that are susceptible to bacterial leaf blight disease, namely Inpari 30, Situbagendit, Cibogo, Luk-Ulo [6], Inpari 3 and Inpago 9 [7].…”
