Physical dormancy can be broken by scarification techniques. There are three scarification techniques, namely mechanical, physical, and chemical scarification. This study aimed to determine which scarification techniques were effective against the breaking of kenaf seed dormancy. The research was carried out at the Seed Laboratory of the Indonesian Sweetener and Fiber Crops Research Institute in January-May 2019. The research method used a randomized block design consisting of seven scarification treatments with four replications. The treatment consists of mechanical treatment, water soaking treatment at 70oC for 3 hours, water soaking treatment at 80oC for 3 hours, water soaking treatment at 90oC for 3 hours, H 2 SO 4 98% soaking for 5 minutes, H 2 SO 4 98% soaking for 10 minutes and H 2 SO 4 98% soaking for 15 minutes. The results showed that the scarification technique had a significant effect on increasing the viability of kenaf seeds. Scarification treatment with H 2 SO 4 98% soaking for 5 minutes effectively broke the dormancy of kenaf seed. It could improve the germination of kenaf seeds up to 6%, reduce the number of seed trichomes, and effectively exfoliate the hilum cap . The study suggest that soaking the kenaf seeds in H 2 SO 4 98% for 10 minutes could be adopted to break the seed dormancy to improve the germination.

Benih kenaf memiliki struktur permukaan yang keras, trikoma, dan penutup hilum yang menempel kuat. Hal ini dapat menghambat proses perkecambahan benih kenaf dan menjadi salah satu penyebab dormansi fisik. Dormansi fisik dapat dipatahkan dengan teknik skarifikasi. Terdapat tiga teknik skarifikasi, yaitu skarifikasi mekanik, fisik, dan kimia. Tujuan penelitian ini yaitu untuk mengetahui teknik skarifikasi yang efektif terhadap pematahan dormansi benih kenaf. Penelitian dilaksanakan di Laboratorium Benih Balai Penelitian Tanaman Pemanis dan Serat pada bulan Januari-Mei 2019. Metode penelitian menggunakan rancangan acak kelompok yang terdiri atas tujuh perlakuan skarifikasi benih kenaf dengan empat ulangan. Perlakuan terdiri dari perlakuan mekanik, perendaman air suhu 70oC selama 3 jam, perendaman air suhu 80oC selama 3 jam, perendaman air suhu 90oC selama 3 jam, perendaman H 2 SO 4 98%  selama 5 menit, perendaman H 2 SO 4 98% selama 10 menit dan perendaman H 2 SO 4 98% selama 15 menit. Banyaknya benih tiap perlakuan adalah 400 biji. Hasil penelitian menunjukkan bahwa teknik skarifikasi berpengaruh nyata terhadap pematahan dormansi benih kenaf.

Some putative sugarcane mutants originating from the PS 881 variety have been produced through mutation induction using colchicine. The study aimed to determine the effect of colchicine induced on genome size and agronomical traits, and its correlation with sugarcane putative mutants production. The experiment was conducted at the UPBUP of IAARD, Bogor, July 2018-April 2019. The research was carried out in an augmented design in randomized complete block design, using 35 genotypes of the first generation G0 (30 putative mutants from colchicine 0.03 and 0.05%, five check varieties). The genome size, agronomical traits, i.e. stem number, length, diameter, and weight per meter; internode number and length; brix, and production, were evaluated. This result showed that colchicine increased 5.03-13.64% genome size of putative sugarcane mutants compared to the original variety PS 881. It is significantly different for almost all of agronomical traits. The genome size was significantly correlated very positively with brix and significantly positively with stem length and diameter, and production. Path analysis showed that stem (weight per meter and length) has a direct effect on production, in contrast, genome size, stem diameter, internode number, and brix have an indirect effect through stem weight per meter to production. Indirect selection to obtain high production can be done through stem (weight per meter and length), consider for genome size, stem diameter, internode number, and brix. This is  experimental preliminary information, validation on field is needed among direct and indirect of production components to production.

The experiment was arranged in a Complete Randomized Design with 7 treatments and three replications. The seven treatments were: control (no reprocessing), thermal treatment steam heat at 90 - 100°C for 0, 30, 60, 90 minutes and non-thermal immersionin ozonized water for 0, 20, 40, dan 60 minutes.

Dua galur lainnya yaitu RC.74 dan RC.104 beradaplasi sempit (spesiik lokasi) sesuai untuk daerah Bayan Nusa Tenggara BaratKata kunci : Ricmus commums, stabilitas hasil, spesifik lokasi ABSTRACT Yield Stability of Castor LinesThe experiment was conducted in two locations at Sandubaya (East I-ombok) and Bayan (West lombok), in planting session 1998/1999 and 1999/2000 from November 1998 to September 2000 This experiment was aimed to ind oul superior lines of castor, high productivities, that can be developed in speciic dry area in easten pat of Indonesia. The trial was arranged in randomized block design with 3 replications. Nine lines, RC.67, RC.74, RC.86, RC.104. RC.106. RC.220, RC. 221, RC6I, KF.VIII and 3 control varieties, Asembagus 22, Asembagus 60 and Asembagus 81 were used as treatment. Results of this experiment found out 3 superior lines: RC 67, RC.221 and RC.64, which have the same potential with Asb.81 variety, have broad adaptation (stable lines). Two other lines : RC.74 and RC.104 have narrow adaptation (speciic location) just for Bayan.

Salah satu usaha untuk mengatasinya adalah dengan menanam berbagai jenis tanaman sela di antara kelapa atau disebut polatanam campuran. Untuk mengetahui penggunaan dua model pola¬ tanam padi dan kacang tanah di antara kelapa yang lebih produktif dan menguntungkan telah dilakukan penelitian di Desa Caringinnunggal, Kecamatan Ciracap, Kabupaten Sukabumi, Propinsi Jawa Barat dengan jenis tanah podsolik merah kuning, tipe iklim Cl (Oldeman), dan kctinggian tempat 250 m dpi. Penelitian dilaksanakan secara on farm dengan menggunakan mctode observasi dimulai dai bulan Juni 1999 sampai dengan Maret 2000. Perlakuan yang diuji adalah dua model polatanam yaitu : (1) padi dan kacang tanah (75% : 25%); (2) padi dan kacang tanah (50% 50%) dengan dasar kelapa. Hasil penelitian menunjukkan bahwa penggunaan dua model polatanam (padi + kacang tanah) campuran berpengaruh positif terhadap tanaman pokok kelapa, khususnya pada karaktcr jumlah daun, jumlah bunga betina, setting buah dan produksi nira. Produktivitas tanaman sela padi pada dua model yang diuji sangat rendah. Produktivitas padi pada model satu adalah 798 kg dan model dua 496 kg gabah kenngpanen atau masing-masing setara dengan 1 064 kg dan 992.0 kg gabah keing panen/ha petanaman kelapa. Produktivitas tanaman sela kacang tanah pada dua model yang diuji cukup tinggi. Produktivitas kacang tanah pada model satu adalah 670 kg dan model dua I 220 kg polong basah atau masing-masing setara dengan 2 680 kg dan 2 440 kg polong basah/ha petanaman kelapa. Hasil. analisis finansial menunjukkan, bahwa model polatanam satu memberikan keuntungan Rp. 904 300/ha/th, B/C ratio 1.12 dan LKM 0.0495, sedang model dua membei keuntungan Rp. 1 367 800/ha/th, B/C ratio 1.17 dan LKM 0.0333.Kata kunci: Cocos nucifera, Oryza saliva, Arachis hipogea, polatanam campuran, Sukabumi ABSTRACT Two model of rice (Oryza sativa> and peanut (Arachis hipogea) cropping system on coconut land in Sukabumi Regency -West JavaThe productivity of coconut smallholder's income, in general, is still low. One of the solutions to overcome this problem is to introduce some intercrops in the coconut land. This study was conducted in Cainginnunggal Village, Ciracap, Sukabumi Regency, West Java Province, rom June 1999 to March 2000. The soil is red yellow podsolic, the climate is C (Oldeman), the altitude is 250 m above sea level. This research used on-farm method with two models, namely (1) ice and peanut 75%: The results of the research showed that the intercropping of rice and peanut on coconut land had good effect on coconut as the main crop, particularly on the coconut leaf number, female lower number, ruit setting, and toddy production. The productivity of ice as the intercrop was very low. On the first model was 798 kg and on the second model was 496 kg harvest dry seed or eqivalent to 1.046 kg and 992 kg harvest dry seed/ha of coconut land.
