<p>Perbanyakan karet (Hevea brasiliensis Muell. Agr.) dengan okulasi cokelat membutuhkan waktu yang lama dalam pembibitannya, sedangkan perbanyakan dengan okulasi hijau belum banyak dilakukan karena tingkat keberhasilan masih sangat rendah. Salah satu faktor yang diduga berpengaruh terhadap keberhasilan okulasi hijau adalah umur bibit batang bawah. Tujuan penelitian adalah mengetahui pengaruh perbedaan umur batang bawah terhadap persentase keberhasilan okulasi hijau pada tiga klon karet. Penelitian dilaksanakan di Kebun Percobaan (KP.) Pakuwon, Balai Penelitian Tanaman Industri dan Penyegar pada bulan Januari-Desember 2013. Penelitian menggunakan rancangan petak terbagi, tiga ulangan dan ukuran petak 25 pohon. Petak utama adalah jenis klon batang bawah, terdiri dari 3 klon, yaitu K1 = AVROS 2037, K2 = PB 260, dan K3 = GT 1. Anak petak adalah umur batang bawah terdiri dari 4 taraf, yaitu U1 = 4 bulan, U2 = 5 bulan, U3 = 6 bulan, U4 = 7 bulan. Okulasi dilakukan dengan cara membuka kulit batang bawah, kemudian entres dimasukkan ke dalam jendela sayatan hasil pembukaan. Pengikatan sambungan dilakukan dengan menggunakan plastik khusus dengan cara dililitkan dari bawah ke atas. Pengamatan dilakukan terhadap persentase keberhasilan okulasi hijau pada umur tiga minggu setelah okulasi (MSO). Hasil penelitian menunjukkan bahwa keberhasilan okulasi hijau pada tanaman karet dipengaruhi oleh umur batang bawah. Untuk Klon PB 260 dan GT 1, makin tua umur batang bawah sampai maksimum 7 bulan di polybag maka semakin meningkat persentase keberhasilan okulasi, sedangkan pada klon AVROS 2037 belum memperlihatkan perbedaan yang nyata.</p><p>Kata kunci: Hevea brasiliensis, umur batang bawah, klon, keberhasilan okulasi hijau</p><p>Propagation of rubber (Hevea brasiliensis Muell. Agr.) using brown budding need a long time in the nursery, whereas the propagation usinggreen Budding has not yet been done due to the success rate is still very low. One of the factorthat might influence the successfulness of green budding is rootstock age.. The purpose of this study was to determine the effect of different age of rootstock on the percentage of green budding success in three rubber clones. The experiment was conducted at the Pakuwon experimental station (ES), Indonesian Industrial and Beverage Crops Research Institute, from January-December 2013. The research was done using split plot design with three replications, and the plot size is 25 trees. The main plot was the type of clones used for rootstock that comprised of 3 clones: K1 = AVROS 2037, K2 = PB 260, and K3 = GT 1. Meanwhile, the subplots were rootstock age consists of 4 levels, namely: U1 = 4 months, U2 = 5 months, U3 = 6 months, U4 = 7 months. Observations were made on the percentage of green budding success at 3 weeks old after grafting . The results showed that the success of the green budding on the rubber plants is influenced by the age of rootstock. The use of rootstock up to 7 months old in polybag in PB 260 dan GT 1 clones would increase the percentage of grafting success, whereas AVROS 2037 clone did not show any significant different.</p><p> </p>

<p><strong>The effect of living post and pepper vines primings on the pepper yield</strong></p><p>To obtain good yield of pepper, farmers fequently apply various treatments to their crops, including pruning of the pepper vines and or their living post. Studies on the aspects of the pruning ae however very limited. Therefore a ield experiment was conducted to investigate the effects of pruning of pepper vines and their living post on the pepper yield. The experiment was carried out at Sukamulya Research Station, Sukabumi. A split plot design with three rcplicaties was used. The main plot was the pruning of living post, and the sub plot was the pruning of pepper vines Plot size was 20 plants per plol wilh spacing of 2.5 m x 2.5 m Results showed that there was signiicant interaction between the pruning of living post and pepper vines. The pruning of living post may be carried out either 3 times (October, January and April) or twice (October and January) a year. However. If the pruning of the living post is carried out 3 times per year, Ihe vine would be pruned once a year or not at all. On the other hand, if the pruning of living post is carried out twice a year, the pepper vines would be pruned 6 times a year.</p>

A Field trial was conducted at the aerobic rice experimental field of the NationalCereals Research Institute (NCRI), Badeggi, Nigeria (9 ° 04 N and 6° 7 E)in 2007 and 2008 wet seasons to determine the weed competitiveness andperformance of inter Ã¢â‚¬Â and intra‐specific aerobic rice (Oryza sativa L.) varietiesunder seven weeding regimes. The trial was laid out in a split plot designwith the two varieties of rice (NERICA 1 as inter Ã¢â‚¬Âspecific and FARO 46 asintra Ã¢â‚¬Âspecific) assigned to the main plot while seven weeding regimes (hoeweeding at 25, 45, and 65 days after sowing (DAS), 25 DAS, 45 DAS, 25 and45 DAS, application of 3’,3’ Ã¢â‚¬Â dichloropropionanilide /2, 4 – Dichlorophenoxyacetic acid (orizo plus R) by Candel Company Ltd. at 3.5 kg active ingredient(ai )ha Ã¢â‚¬Â1 at 25 DAS, hoe weeding at 25 DAS followed by orizo plus at 3.5 kg aiat 45 DAS and weedy check) constituted the sub – plots. The treatmentswere replicated three times in a split plot design. From the results, interspecificvariety (NERICA1) had better weed suppression ability with highergrain yield of 3.1 t ha Ã¢â‚¬Â1 than the intra‐specific variety (FARO 46). Weed controlwas better when hoe weeding was done at 25, 45 and 65 DAS or 25 and45 DAS and at 25 DAS followed by orizo plus at 45 DAS than in other treatments.However, hoe weeding at 25, 45 and 65 DAS gave significantlygreater grain yield than other treatments. Although economic yield was obtainedfrom hoe weeding at 25 DAS followed by orizo plus at 45 DAS.

Field experiment was conducted in 2019 at Haskell Agriculture Laboratory, Concord, NE, USA. Goal of the study was to test the influence of PRE-EM herbicides on the Critical Time for Weed Removal (CTWR) in dicamba-tolerant soybean. The study was arranged in a split-plot design which consisted of four herbicide regimes as main plot treatments and seven weed removal timings as subplot treatments, with four replications. The herbicide regimes included: (1) no PRE and glyphosate, (2) acetochlor and dicamba as PRE and glyphosate as POST, (3) acetochlor and dicamba as PRE and glyphosate and dicamba as POST, and (4) acetochlor and fomesafen as PRE and acetochlor, glyphosate and dicamba as POST. The five weed removal times included the V1, V3, V6, R2 and R5, and there were also weedy and weed-free season long plots. By utilizing herbicide regimes, the CTWR was delayed to 632 GDD (until V4 soybean growth stage, 28 days after emergence) for acetochlor and dicamba as PRE and glyphosate as POST, 861 GDD (until V6 soybean growth stage, 32 days after emergence) for acetochlor and dicamba as PRE and glyphosate and dicamba as POST, and 1060 GDD (until R1 soybean growth stage, 42 days after emergence) for acetochlor and fomesafen as PRE and acetochlor, glyphosate and dicamba as POST.

<p>Kentang merupakan sayuran yang memiliki prospek untuk mendukung program diversifikasi pangan. Akan tetapi saat ini produksi di dalam negeri masih rendah akibat penggunaan benih yang kurang bermutu. Sistem irigasi tetes berpeluang untuk diterapkan pada produksi benih kentang G0. Penelitian  bertujuan untuk mengetahui pengaruh frekuensi dan volume fertigasi terhadap produksi benih G0 kentang pada sistem irigasi tetes. Penelitian  dilaksanakan sejak bulan Mei sampai dengan September 2016 di Rumah Kassa Desa Cikahuripan, Lembang, Bandung Barat, Jawa Barat dengan ketinggian 1.200 m dpl. Percobaan menggunakan rancangan petak terpisah (split plot design) dengan rancangan acak kelompok lengkap dan tiga ulangan. Sebagai petak utama adalah frekuensi fertigasi sebanyak 3, 5, dan 7 kali. Sebagai anak petak adalah volume fertigasi (ml) setiap aplikasi, yaitu 100, 200, 300, dan 400. Hasil penelitian menunjukkan tidak terjadi interaksi antara perlakuan frekuensi dan volume fertigasi terhadap semua peubah pengamatan. Frekuensi fertigasi terbaik terhadap bobot ubi per tanaman umur 100 HST adalah lima kali, yaitu jam 7, 10, 12, 14, dan 16. Volume fertigasi terbaik terhadap jumlah ubi ukuran besar umur 100 HST adalah 300 ml per aplikasi per polibag. Volume dan frekuensi fertigasi terbaik ini diharapkan tidak saja meningkatkan produksi benih, tetapi juga keuntungan usahatani yang diperoleh. Perlu dilakukan penelitian lebih lanjut untuk menginduksi pengumbian dengan mengalihkan ukuran ubi menjadi peningkatan jumlah ubi sebagai tujuan produksi benih G0.</p><p><strong>Keywords</strong></p><p><em>Solanum</em> tuberosum L.; Irigasi tetes; Fertigasi; Frekuensi; Volume</p><p><strong>Abstract</strong></p><p>Potato is one of vegetables that can be used as an alternative to support food diversification programs. But the potato production domestically is still low because of low quality seed. One of the potato seed technologies that can be developed is arragement of fertigation volumes and frequencies on drip fertigation. The objective of this research was to determine the best fertigation volume and frequency in G0 potato seed production in drip irrigation. This research was conducted from May to September 2016 at Screen House Cikahuripan Village, Lembang, Bandung on 1,200 m asl. The treatments were arranged in split plot design with randomized complete block design and three replications. The main plot was fertigation frequency which was consisted of three levels; 3, 5, and 7 times per day. The subplot was fertigation volume which was consisted of four levels; 100, 200, 300, and 400 ml per aplication. The result showed there was no interaction between fertigation frequency and volume on all observation. The best fertigation frequency on tuber weight per plant at 100 day after planting was five  times, i.e. 7, 10, 12, 14, and 16 o’clock. The best fertigation volume on number of big tuber at 100 day after planting was 300 ml per application. The best fertigation volume and frequency will increase not only seed production, but also profit of bussiness. Next research will be done to induction tuberization by transfering measurement of tuber to increase the amount of tuber as goal of production of G0 potato seed.</p><p> </p>
