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>
