<p>Percobaan penambahan N pada POC sebagai foliar fertilizer untuk tanaman padi ratoon telah dilaksanakan Di Kota Padang, September 2017 - Januari 2018, Tujuan penelitian mendapatkan kombinasi dari pemberian Nitrogen buatan terhadap POC untuk meningkatkan pertumbuhan dan hasil padi ratoon.  Percobaan disusun dalam bentuk split plot, dengan petak utama adalah pemangkasan terdiri atas 2 taraf yaitu; tidak dipangkas dan dipangkas.  Anak petak berupa pemberian foliar fertilizer terdiri atas 4 jenis yaitu; 0 (F1); 800 mg L<sup>-1</sup> Urea (F2); 25 ml L<sup>-1</sup> + Urea (F3); 50 ml L<sup>-1</sup> POC + Urea (F4), diulang 3 kali. Data dianalisis secara statistika menggunakan ANOVA α 5%, jika perlakuan berpengaruh nyata dilakukan dengan uji lanjut BNT α 5%.  Parameter  antara lain; berat hijauan pangkasan, tinggi tanaman,   persentase anakan produktif, umur berbunga dan panen, produksi jerami dan gabah per hektar. Dari hasil percobaan maka disimpulkan bahwa pemberian 800 mg L<sup>-1</sup> pupuk N tunggal dari Urea atau menambahkannya ke dalam POC tidak menguntungkan bagi pertumbuhan dan hasil padi ratoon. Pemangkasan tidak menurunkan hasil gabah yang mencapai 5,37 t ha<sup>-1</sup> GKP, dan peroleh usaha tani masih dapat diimbangi dengan adanya HPT sebesar 3,63 t ha<sup>-1</sup> yang sangat penting bagi program integrasi padi dan ternak. </p><p> </p><p><em>The experiment of an addition of N on foliar fertilizer for ratoon rice plant has been done In Padang City, September 2017 to January 2018, in a semi-intensive paddy field, with altitude 10 m above sea level.

Poor agronomic practices coupled with herbicide mismanagement influence crop performance, yield, weed infestation and environmental hazards. Thus, field experiments were carried out to investigate the effect of spacing and reduced levels of butachlor on weed control and yield of NERICA 1 rice (Oryza sativa L. x Oryza glaberrima L). The experiments were conducted in the 2011 rainy season at the Teaching and Research Farm of the Department of Crop Production and Horticulture, Modibbo Adama University of Technology, Yola, and Lake Gerio, Yola in the 2012 dry season. Yola is located between latitude 9o14? N and longitude 12o28? E in the Northern Guinea Savanna ecological zone of Nigeria. Treatments consisted of four spacings (20 cm x 20 cm, etc.) and four butachlor levels (3, 2, 1, and 0 kg ha-1 a.i.). The experiments were laid out in a split-plot design with spacings assigned to the main plot and butachlor levels assigned to the sub-plot and were replicated three times. Data were taken on percentage establishment, number of leaves per plant, general weed cover, panicle length and grain yield per hectare. Data generated were subjected to analysis of variance. Means showing a significant F-test were separated using LSD. Results obtained showed that butachlor at 1 kg ha-1 and 14 cm x 14 cm spacing gave the highest grain yield of 1441 kg ha-1 and maximum weed control. They are, therefore, recommended for adoption by farmers in Yola and similar environments.

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.

Rice (Oryza sativa L.) is first staple crop of Nepal. The national average yield of rice is less than its potential yield, for which poor agronomic management has been reported as the critical factor. Among various agro-management practices seedling age, seeding density and nitrogen rates significantly affect the growth and yield of rice. The lower seeding density produces the taller plant, more effective tiller, lower sterility and higher grain yield. On the other hand, seedling of older age from higher seeding density gives the lowest yield. Transplanting younger seedling with low seeding density and application of recommended dose of nitrogen gives a higher yield. This article summarizes various effects of seedling age, seeding density and nitrogen rates on plant height, number of effective tillers, number of filled grains, thousand grain weight and grain yield of rice. This information may be useful for maize growers and researchers.

The research aimed to study effect the application of river sand (RS), coconut coir (CC), and banana coir (BC) on growth and yield of rice (Oryza sativa L.) in Ustic Endoaquert. The research was carried out in a green house using 3 × 3 × 3 factorial design. The RS factor consists of three treatment levels which were 0% RS, 25% RS, and 50% RS. Meanwhile, the CC and BC consist of three treatment levels, where each level were 0 Mg ha-1, 10 Mg ha-1 and 20 Mg ha-1. The results showed that RS, CC and BC applications did not have significant effect on plant height. On the other hand, all ameliorant applications had significantly increase leaf length and the highest percentage increasing was in BC (13.49%). The leaf numbers and tiller numbers had relatively similar pattern, except BC that had significantly increased leaf numbers by 77.69% and amount of tiller numbers by 49.45%. Furthermore, for yield components, RS, CC and BC applications had significant increased panicle numbers by 37.76%. It was only RS and BC that increased panicle lenght and the best increasing of 26.82% on RS. Meanwhile, the BC application only increased the rice grain numbers.[How to Cite: Nurdin and F Zakaria. 2013.
