<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>

Abstract Background Rice (Oryza sativa L.) is a common staple food in Nigeria. However, cultivation is impaired by heavy metal contamination, particularly iron (Fe). This study aimed to investigate the impacts of biosynthesized nanoparticles (NPs) in enhancing the growth and yield components of rice sown in ferruginous soil. Viable seeds of O. sativa var. nerica were sown in ferruginous and non-ferruginous soils. After four weeks, the plants were exposed to foliar sprays of biosynthesized NPs from silver nitrate, using extracts of leaves of Carica papaya, Vernonia amygdalina, Moringa oleifera, and Azadirachta indica; and the flowers of Hibiscus sabderiffa, following standard procedure. The originally prepared stock solution was diluted to give 5, 15, and 30% concentrations of each synthesized NP. Results Results showed that soil ferrugenicity impeded the growth and yield of rice. Azadirachta-synthesized NPs was better enhanced in the ferruginous soils, which might be due to Fe interaction and activities. Moreover, there was increased antioxidant activity in the ferruginous rice compared to the non-ferruginous rice, thus it is evidence that ferrugenicity is a major source of physiological stress for the rice plant. Conclusion The study provided evidence that Ag-NPs can enhance plant yield by huge proportions in ferruginous soil, a condition (ferrugenicity) that was hitherto inimical to yield disposition of rice.

Rice (Oryza sativa L.) is a major cereal food crop worldwide, and its growth and yield are affected by several fungal phytopathogens, including Magnaporthe oryzae, Fusarium graminearum, F. moniliforme, and Rhizoctonia solani. In the present study, we have isolated and characterized root-associated bacterial endophytes that have antifungal activities against rice fungal phytopathogens. A total of 122 root-associated bacterial endophytes, belonging to six genera (Bacillus, Fictibacillus, Lysinibacillus, Paenibacillus, Cupriavidus, and Microbacterium) and 22 species were isolated from three rice cultivars. Furthermore, the 16S rRNA sequence-based phylogeny results revealed that Bacillus was the most dominant bacterial genera, and that there were 15 different species among the isolates. Moreover, 71 root-associated endophytes showed antagonistic effects against four major fungal phytopathogens, including M. oryzae, F. graminearum, F. moniliforme, and R. solani. Additionally, the biochemical, physiological, and PCR amplification results of the antibiotic-related genes further supported the endophytes as potential biocontrolling agents against the rice fungal pathogens. Consequently, the findings in this study suggested that the isolated bacterial endophytes might have beneficial roles in rice defense responses, including several bioactive compound syntheses. The outcomes of this study advocate the use of natural endophytes as an alternative strategy towards the rice resistance response.

The experiment was conducted to determine the growth and yield response of pak choi (Brasiccarapa var. Chinkang Genghis Khan) to different foliar fertilizers (viz. vermitea, commercial foliar fertilizer, effective microorganisms [EM-1] and natural farming inputs [NFI]) under protected cultivation. It aimed to evaluate the influence of the different foliar fertilizers on pak choi in terms of growth characteristics, yield components, and pests and disease incidence. Similarly, to conclude which among the foliar fertilizers evaluated will be most the economical for pak choi production. The study was done in the DA-ATI IV-A and LSPU Organic Agriculture Learning Site in the Laguna State Polytechnic University, Siniloan, Laguna in December 2015 to February 2016. A total of 300 plants were used as experimental units in the study. Every treatment was replicated three times and each replication has 10 polyethylene bags planted with two plants each. Data was collected and analysed with the use of the Duncans Multiple Range Test (DMRT). Results revealed that the foliar fertilizers used have no remarkable effect on the weekly height, weekly growth rate, length of leaves, and shoot root ratio of pak choi. Nevertheless, commercial fertilizer significantly increased the mean number of leaves (7.53cm), width of leaves (15.10cm), economic and biological yields (105.10 grams and 106.88 grams, respectively) of pak choi compared with the rest of the treatments, except for vermitea which produced a comparable width of leaves (15.04cm). Also, a significantly lower number of the damaged leaves caused by looper (TrichoplusianiHübner) was noted on plants treated with commercial foliar fertilizer (0.51 leaf per plant). The highest net income was obtained by commercial foliar fertilizer-treated plants, but plants treated with vermitea earned the highest return of investment (ROI). Therefore, the utilization of vermitea in pak choi production can reduce the cost of fertilizer and contribute to an economical production system under protected cultivation.
