This report aims to understand response various herbafarm granule doses of growth and the production of rice (Oryza Sativa L.) fields with the SRI (System Of Rice Intensification). Draft use is a random (group shelves) non factorials namely fertilizer herbafarm granule consisting of 6 standard treatment consisting of 3 test, H0 (Without treatment), H1 (2,43 g/plot), H2 (4,86 g/plot), H3 (7,29 g/plot), H4 (9,72 g/plot), H5 (12,15 g/plot). Each treatment repeat three times, 18 units in order to obtain a plot / experiment, Every a plot there were 9 plants and 7 of them sample plants. The quantity of a crop a whole 162 plant. Then the data obtained by in statistically analysis, further by test different real bnj truthful , 5 percent the first. Based on the research done so it can be concluded that treatment fertilizer herbafarm granule with the SRI give impact on the real parameters, for observation age flowering ( 77.33 hst ) and aged harvest ( 109 .33 hst ) treatment is the best H1 treatment, As for the number of productive saplings (39.90 stem) and heavy of dried grain (87.48 gram) treatment is the best H4 treatment.

Penelitian ini telah di lakukan di Desa Purwodadi Kecamatan Padang Sidimpuan Batunadua Kota Padangsidimpuan Provinsi Sumatera Utara dari bulan Mei sampai dengan bulan Agustus 2017. Tujuan dari penelitian ini adalah untuk menguji beberapa jenis mulsa dalam mengendalikan gulma pada beberapa varietas tanaman padi sawah dengan metode System Of Rice Intensification. Percobaan ini menggunakan Rancangan Petak Terpisah (Split plot design) dalam pola RAK dengan dua faktor. Faktor utama adalah varietas padi sawah yang terdiri dari tiga taraf perlakuan yaitu varitas Aryze H6444, varitas Situ Bagendit dan varitas Siganteng. Faktor anak petak adalah penggunaan mulsa yang terdiri dari empat taraf perlakuan yaitu jerami padi, sekam padi, titonia dan mulsa plastik hitam.Varitas Aryze H6444 Gold dan varitas Siganteng menunjukkan hasil terbaik pada penggunaan mulsa plastik, sedangkan varitas Situ Bagendit menunjukkan hasil terbaik pada mulsa jerami padi. Jenis gulma Ludwigia octovalvis merupakan gulma yang mendominasi pada pemberian mulsa jerami padi, sekam padi dan mulsa plastik. Sedangkan pada mulsa Titonia jenis gulma yang mendominasi adalah gulma Eleusine indica. Penggunaan mulsa plastik lebih baik dari pada penggunaan mulsa Titonia, mulsa jerami padi dan sekam padi dalam menekan pertumbuhan gulma pada tanaman padi sawah dengan sistem SRI. Kata Kunci : pengendalian gulma, jenis mulsa, beberapa varitas,metode SRI.

A field experiment on rice (Oryza sativa L.) crop was conducted at Rice Research Station, Kaul (Kaithal), India during kharif season of 2017 and 2018 to evaluate the optimum schedule of nitrogen application in the rice grown under early and late planting conditions. The treatments consisted of three timings of transplanting (3rd week of June, 1st week of July and 3 rd week of July), four levels of N (90, 120, 150 and 180 kg Nha-1) and four timings of N fertilizer application (½ at transplanting + ½ at 21 DAT, ½ at 21 DAT + ½ at 42 DAT, 1/3 at transplanting + 1/3 at 21 DAT + 1/3 at 42 DAT and LCC based N supply) and were laid out in split-plot design with transplanting time and N levels in main plots and N application time in sub-plots. The growth parameters (plant height, number of tillers/m2 and dry matter accumulation/m2), yield attributing characters (number of panicles/m2 and grains/panicle) and yield (grain and straw yield) of rice crop reduced significantly under late planting (3rd week of July) as compared to that under the two earlier plantings (3rd week of June and 1stweek of July) whereas the two earlier plantings were at par in respect of these parameters. The growth, yield attributes and the yield increased with every increase in N application rates but the increase was significant up to 150 kg Nha-1. The highest yield was (7.33 tha-1), however, obtained with the crop transplanted early (up to1st week of July) and supplied with 150 kg Nha-1.Application of N in three equal splits (at 0, 21 and 42 DAT or as per LCC schedule), being at par, resulted into higher yield (grain and straw) than the N application in two equal splits. The net returns and B: C ratio increased appreciably with increase in N application levels upto 150 kg Nha-1 obviously due to increase in crop yield.

Penelitian tentang rancang bangun prototipe mesin penyiang mekanis pada budidaya tanaman padi (Oryza sativa L.) system of rice intensification (SRI) dilaksanakan pada bulan Febuari sampai dengan April 2009. Tujuan penelitian ini adalah menciptakan sebuah prototipe mesin penyiang gulma padi sawah mekanis yang efisien dan berkapasitas tinggi, sesuai dengan kebutuhan petani sehingga dapat mengatasi masalah keterbatasan tenaga kerja untuk melakukan penyiangan gulma. Penelitian ini dilaksanakan dengan metode rancang bangun yang menggunakan pendekatan hubungan sebab akibat, diagram alir proses,  pembuatan model matematis. Perancangan konsep produk, dimulai dengan analisis kebutuhan, blok diagram dan analisis validasi. Analisis validasi  mesin melihat kinerja mesin keseluruhan. Hasil penelitian diperoleh kapasitas efektif penyiangan 0,0547 ha/jam,  efisiensi lapang 49,37 %, kehilangan waktu belok  32,03 %, tingkat kerusakan tanaman 7,7 %,  gulma tidak tersiangi 3,12 %. Daya motor terpakai 2,52 Hp, tingkat kebisingan dalam batas diizinkan. Penyiangan dengan mesin tergolong kerja sedang. Hasil analisis ekenomi menunjukan biaya pokok penyiangan per hektar Rp. 463.322,67 dengan BEP penyiangan 29,03 ha per tahun,  NPV  Rp. 7.139.779,01 dan B/C Ratio 1,093 pada tingkat suku bunga 10 %, yang berarti mesin layak digunakan. Agar mesin dapat diterima di masyarakat, perlu sosialisasi, penyempurnaan sistem transmisi, penggunaan material lebih ringan serta perlu pengaturan jarak dan kelurusan  barisan tanam agar tercapai kinerja mesin yang optimal.

Wet And Dry Seasons

Field experiments were conducted during the wet and dry seasons of 2002 and 2003 at Tamil Nadu Agricultural University Farm, Coimbatore, India to study the effect of practices recommended in the system of rice intensification (SRI) on the yield attributes, yield and water productivity of rice (Oryza sativa L.). The experiments were laid out in a randomized block design with three replications. The treatments were i) using 21-day-old (conventional) or 14-day-old (dapog nursery) seedlings; ii) crop geometry at 15 × 10 cm, 20 × 20 cm or 25 × 25 cm; iii) irrigation at 5.0 cm depth (conventional) or 2.0 cm depth when hair-line cracks developed (SRI); iv) weed control (conventional and SRI weeding), and v) nitrogen management (recommended and LCC-based N application) during the wet season of 2002. During the second crop season (dry season, 2003), all the treatments were repeated except nitrogen management, since there was no response to LCC-based N in the wet season. The treatments were slightly modified based on the results of the wet season crop. The yield attributes (panicle length, number of panicles hill-1, total number of grains panicle-1) were significantly higher in the treatment involving 14-day-old seedlings + 25 × 25 cm spacing + water-saving irrigation + LCC-based N management + SRI weeding than in the other treatments during the wet season. During the dry season, greater values of panicle length, no. of panicles hill-1 and filled grains panicle-1 were recorded in the treatment combination involving 14-day-old seedlings + 25 × 25 cm spacing + water-saving irrigation + SRI weeding. The grain yield and water productivity were significantly increased when applying SRI weeding with 14-day-old dapog seedlings planted at 25 × 25 cm spacing to achieve yields of 7009 and 5655 kg ha-1, and 0.610 kg and 0.494 kg per m3 of water, respectively, in the wet and dry seasons.
