The research method used was the experimental method with Randomized Block Design (RBD) with five treatments repeated five times. Data were analyzed by variance and followed by Least Significant Difference (LSD) Test. The testing material consisted of five genotypes of cayenne pepper, namely one of the new superior varieties (Ratuni Unpad), and four varieties (CR8873, Dewata, Taruna, and Rabani). The tests were carried out in Sukamantri, Ciamis Regency in 983 m asl in August 2017 to February 2018. The observations were made on the character of the results and components of results which included the seed length, the seed diameter, the seed weight per unit, the seed weight per plant, the seed weight per plot, and the seed weight per hectare. The test results showed that there were differences in phenotypic characters between the five genotypes tested. The Dewata, Ratuni Unpad, and CR8873 genotypes show the highest potential yield (8.34 tons/ha, 7.71 tons/ha, and 7.24), with the character of fruit weights per fruit of 1.382 grams, 0.911 grams respectively. and 1,311 grams.PENAMPILAN KARAKTER FENOTIPIK HASIL PADA LIMA GENOTIP CABAI RAWITPenelitian ini bertujuan untuk mengetahui penampilan karakter fenotipik pada lima genotip cabai rawit di Sukamantri, Kabupaten Ciamis.

The study was carried out in the Ciparanje experimental garden of Padjadjaran University in Jatinangor in April to July 2017. The design used in this study was a Randomized Block Design which was repeated three times. The soybean seeds used are Anjasmoro varieties. Tricho-G as a source of Trichoderma sp. was used as a seed coating material. Bokashi cow manure and the soil used were from paddy fields. Other ingredients used were Urea, SP-36, KCl, and pesticides with the active ingredient Profenofos. The step of the research is bokashi application, seed coating, storage, planting, fertilizer application, and observation. The results show that the combination of seed coating using Trichoderma sp. and bokashi application had an effect on increasing the number and weight of seeds per plant. Coating of seeds with Trichoderma sp. low doses can still maintain plant growth and has a positive effect on crop yields.PENGARUH PELAPISAN BENIH TrichoDERMA SP.

Penelitian dilaksanakan di kebun percobaan Ciparanje Universitas Padjadjaran Jatinangor pada bulan April sampai dengan Juli 2017. Rancangan yang digunakan dalam penelitian ini yaitu Rancangan Acak Kelompok yang diulang tiga kali. Benih kedelai yang digunakan yaitu varietas Anjasmoro. Tricho-G sebagai sumber Trichoderma sp. digunakan sebagai bahan pelapis benih. Pupuk Bokashi kotoran sapi dan tanah yang digunakan berasal dari tanah sawah. Bahan-bahan lain yang digunakan yaitu pupuk Urea, SP-36, KCl, dan pestisida dengan bahan aktif  Profenofos. Langkah penelitian yang dilakukan adalah pemberian bokashi, pelapisan benih, penyimpanan, penanaman, pemupukan, dan pengamatan. Berdasarkan hasil penelitian ini dapat disimpulkan bahwa kombinasi pelapisan benih menggunakan Trichoderma sp. dan pemberian bokashi berpengaruh dalam meningkatkan jumlah dan bobot biji per tanaman.

The experimental design used was Factorial Randomized Group Design consisting of two factors, namely the administration of three levels of bokashi fertilizer and seed coating with Thiamethoxam and Trichoderma which consisted of five levels. The combination of the two factors contained 15 treatments which were repeated three times. DSAASTAT application was used in the further testing. The implementation of the research includes: power testing, weighing, seed vigor test, land preparation, application of bokashi fertilizer, planting, maintenance, destruction, main observations and supporting observations. The results showed that there was no effect of interaction between bokashi fertilizer and seed coating on seed vigor and growth of Anjasmoro cultivar soybeans. Giving 300 g / polybag of bokashi fertilizer can increase soybean plant growth. Coating with Trichoderma sp. 1 g / 100 seeds is the best dose of seed vigor, but the treatment without seed coating is not significantly different from other seed coating treatmentsPENGARUH PUPUK BOKASHI DAN PELAPISAN BENIH TERHADAP VIGOR BIBIT DAN PERTUMBUHAN KEDELAIPenelitian ini bertujuan untuk menentukan dosis pupuk bokashi dan pelapisan benih yang dapat memberikan pengaruh baik pada vigor bibit dan pertumbuhan kedelai. Rancangan percobaan yang digunakan yaitu Rancangan Acak Kelompok Faktorial yang terdiri dari dua faktor yaitu pemberian pupuk bokashi tiga taraf dan pelapisan benih dengan Thiamethoxam dan Trichoderma sp. yang terdiri dari lima taraf. Kombinasi dari kedua faktor terdapat 15 perlakuan yang diulang tiga kali. Uji lanjut menggunakan aplikasi DSAASTAT. Pelaksanaan penelitian meliputi:uji daya, penimbangan, uji vigor bibit, persiapan lahan, aplikasi pupuk bokashi, penanaman, pemeliharaan, destruksi, pengamatan utama, dan pengamatan penunjang. Hasil penelitian menunjukkan bahwa tidak ada pengaruh interaksi antara pemberian pupuk bokashi dan pelapisan benih terhadap vigor bibit dan pertumbuhan kedelai kultivar Anjasmoro. Pemberian pupuk bokashi osis 300 g/polybag dapat meningkatkan pertumbuhan tanaman kedelai. Pelapisan dengan Trichoderma sp. 1 g/100 butir benih merupakan dosis terbaik terhadap vigor bibit. Namun, perlakuan tanpa pelapisan benih tidak berbeda nyata dengan perlakuan pelapisan benih lainnya.","PeriodicalId":370796,"journal":{"name":"Jurnal Penelitian Saintek","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129144426","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
