<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. The experiment was arranged in the form of a split plot, with the main plot being a pruning consisting of 2 levels ie; not pruned and. The subplot of fertilizer foliar consists of 4 types namely; 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). Experiment repeated 3 times. Data were analyzed statistically by using ANOVA 5% if treatment had real effect done with BNT test 5%. Parameters include; the weight of crop forage, plant height, a percentage of productive tillers, flowering age and harvest, straw and paddy production per hectare. From the experimental results, it was concluded that administering 800 mg L<sup>-1</sup> of single N fertilizer from Urea or adding it to POC as foliar fertilizer was not favorable for growth and yield of ratoon rice. Pruning does not reduce grain yield reaching 5.37 t ha<sup>-1</sup>, and earn farming can still be offset by the existence of HPT of 3.63 t ha<sup>-1</sup>.</em></p><p> </p><p> </p>

Experiments were carried out to assess some insecticide modules against major insect pests of rice. Each module consists of a basal application of carbofuran 3G @ 1 kg a.i ha-1 at 20 DAT and Rynaxypyr 20 SC @ 30 g a.i ha-1 at 45 DAT except untreated control. All modules differ with each other only in third treatment which was applied in 65 DAT. The third treatment includes: Imidacloprid 17.8 SL @ 27 g a.i ha-1, Pymetrozine 50 WG @ 150 g a.i ha-1, Triflumezopyrim 106 SC @ 27 g a.i ha-1, Buprofezin 25 SC @ 250 g a.i ha-1; Glamore (Imidacloprid 40+Ethiprole 40% w/w) 80 WG @ 100 g a.i. ha-1, Thiacloprid 24 SC @ 60 g a.i ha-1, Azadirachtin 0.03 EC @ 8 g a.i ha-1, Dinotefuran 20 SG@ 40 g a.i ha-1 and untreated control. All the treated plots recorded significantly lower percent of dead heart, white ear- head caused by stem borer and silver shoot caused by gall midge. Module with Pymetrozine 50 WG @ 150 g a.i ha-1 treated plot recorded significantly higher per cent reduction of plant hoppers (>80% over untreated control) and produced higher grain yield (50.75 qha-1) than the other modules. Among the different treated modules the maximum number of spiders was found in Azadirachtin 0.03 EC @ 8 g a.i ha-1 treated module plot followed by other treatments.
