This study aims to determine the Response Growth and Production of Crops (Brassica juncea L.) Against Watering Time Interval In Various Hydroponics Media. The research was conducted at the experimental gardens of Faculty of Agriculture, Faculty of Agriculture, University of Medan Area, located on No. Pond Street. 1 Medan Estate. This research was conducted from October 2013 until December 2013. The design used was RAL Factorial, with 2 replications, 10 combinations. The first factor of the hydroponic planting medium is: M1: Frying Roots, M2: Coconut Coir Powder, M3: Fryer Seal, M4: Rokwool, and M5: Sawdust, the second factor is the time interval: I1: 3 hours a day I2: 5 hours a day, starting from 08:00 a.m to 06:00 p.m. The result of this research indicates that the treatment of watering liquid fertilizer with different time interval does not show a real effect on the growth of mustard plants, Media treatment used on hydroponic systems have an influence very evident on the parameters of plant height, leaf number, leaf area, production weight and significant effect on leaf level parameters, influential planting medium and have the best number is M3 (fuel husk). Interaction interval of watering time on various hydroponic media did not have a significant effect on observed parameters, namely: plant height, leaf number, wet weight, and weight of production, while the leaf color parameter had significant effect on leaf width.
<p class="8AbstrakBahasaIndonesia">Penelitian Budidaya Tanaman Sawi (<em>Brassica Juncea L.</em>) Pada Media Tanam Yang Berbeda Secara Vertikultur. Tujuan penelitian untuk mengetahui teknik budidaya tanaman Sawi yang lebih efisien dengan menggunakan media tanam yang berbeda secara vertikultu. Penelitian dilakukan di kebun percobaan Fakultas Pertanian Universitas Medan Area yang berlokasi di jalan Kolam No. 1 Medan Estate, Kecamatan Percut Sei Tuan dengan ketinggian tempat 25 m dari permukaan laut, topografi datar dan jenis tanah alluvial. Penelitian ini dilaksanakan Mei 2014 / Juli 2014, penelitian mengunakan rancangan acak kelompok faktorial yang terdiri dari 2 faktor perlakuan, yaitu Faktor pertama Pola Budidaya (P) yang terdiri dari 3 taraf, P1 = Konvensional P2 = Vertikultur bambu P3 = Vertikultur botol plastik bekas. Faktor kedua Media tanam (M) yang terdiri dari 2 taraf : M1 = tanah + pupuk kandang sapi dan M2 = tanah + pupuk kompos sayuran. Hasil penelitian menunjukan bahwa pemberian pupuk kandang sapi dan kompos sayur tidak menunjukan perbedaan yang nyata terhadap pertumbuhan tanaman sawi, tetapi pola tanam menunjukan pengaruh yata pada pertumbuhan tanaman sawi hijau (P1) konvesional dan disusul dengan pelakuan perikultur yang tidak jauh berbeda yaitu P2 (verikultur dengan Bambu). Secara umum penelitian tidak menunjukan hasil yang berbeda nyata tetapi pengunaan pola tanam verikultur dengan bambu dapat digunakan karea hasil tidak jauh berbeda dengan konvensional.</p>
Tujuan penelitian ini adalah mengetahui respon pertumbuhan dan produksi tanaman cabai merah (Capsicum annum L.) di berbagai media tanam dan pemberian pupuk organik. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) Faktorial yang terdiri dari dua faktor. Faktor pertama adalah pemberian pupuk Tiens Golden Harvest (notasi H) terdiri dari 4 taraf, yaitu: Ho = pupuk dasar, H1 = 0,5 l/ha, H2 = 1 l/ha dan H3 = 1,5 l/ha. Faktor kedua adalah pemberian sekam padi dan arang (notasi P) terdiri dari 3 taraf, yaitu: Po = 100 % tanah (sebagai kontrol), P1 = Tanah : Sekam Padi = 3 : 2 dan P2 = Tanah : Arang = 3 : 2. Parameter yang diamati dalam penelitian ini adalah: tinggi tanaman, jumlah cabang, umur panen dan berat produksi per plot. Hasil penelitian menunjukkan bahwa perlakuan dosis pupuk Tiens Golden Harvest dapat meningkatkan tinggi tanaman, jumlah cabang, berat produksi per plot, dan mempercepat umur panen. Perlakuan media tanam dengan penambahan sekam padi dapat lebih meningkatkan tinggi tanaman, jumlah cabang dan berat produksi per plot, tetapi tidak dapat mempercepat umur panen, dibandingkan dengan yang menggunakan penambahan arang. Interaksi antara dosis pupuk Tiens Golden Harvest dan media tanam berpengaruh tidak nyata terhadap semua parameter yang diamati.
The research was conducted in farm experiment faculty of agriculture, the University of Medan Area The research was done by using the method of random designs that the group 's group (RAK) are composed of two treatment factors, those are: 1) Mixed of baglog compostwith cows manure (notation B) 2) Organic fertilizer, liquid waste of palm(notation K) consisting of 4 treatments, are Ko= without treatment, K1=liquid waste 50 ml/l/plants, K2=chemicals 75ml/l/plants, K3= liquid waste 100 ml/l/plants. Every treatment repeated as much as two times. The parameters in this study is focus on the diameter of steam (cm), flowering age (day), total of pods/plants (fruits), long pods/plants (cm), thick/ plants (g), and production/plot (kg). The conclusion of this study as follows: 1) giving the mixed Baglog compost with cows manure had no real effects to the diameter of steam, total pods per plants, long pods/plants, thick and plants, and productions/plot but it had real effects to flowering age. 2) giving thePOC liquid waste ofpalms had the real effects to the diameter of steam 5 MST ages, flowering age, total pods per plants, long pods per plants, thick per plants, and production. And 3) the combination both of factors had real effects to long pods per plants, and production per plot, but had no real effects to the others parameters.
<h1>In the Indonesian economy, the oil palm commodity plays a pretty bright role because it serves as a source of foreign exchange. The need to develop technology in producing superior seeds. In this study discuss about the Influence of Giving Fertilizer and Mikoriza Against the Growth of Palm Oil Plants (Elaeis guineensis jacq.) In Pre-Nursery Nursery. This study aims to determine the effect of manure and mycorrhizal fertilization as well as its interaction on the growth of coconut plants in pre-nursery nurseries. The study was designed by Factorial Randomized Block Design consisting of 2 treatment factors. The first factor of treatment of manure (K) consisting of 4 levels, namely: K0 = 0 kg / polybag, K1 = 0.15 kg / polybag, K2 = 0.30 kg / polybag, and K3 = 0.45 kg/polybag. The second factor of mycorrhizal treatment (M) consisting of 4 levels, namely: M1 = 12.5 g/polybag, M2 = 25.0 g/polybag, M3 = 37.5 g / polybag. The results showed that the treatment of cow manure up to 0.45 kg/polybag can increase the height of seedlings, stem diameter, total leaf area, wet weight of seedlings and dry weight of seedlings, but did not affect the number of oil palm seedlings.Mikoriza treatment up to 37, 5 g / polybags can increase seed height, stem diameter, total leaf area, wet weight of seedlings and dry weight of seedlings, but have no significant effect on the number of oil palm seedlings. The interaction between cow manure and mycorrhiza had no effect on all parameters observed.</h1>
