A series of on-farm fi eld experiments were conducted in two locations in Padang, Koto Panjang and Koto Tingga, West Sumatera, Indonesia in 2015. The purpose of the experiment was to establish the formula of organic fertilizer derived from Tithonia supplied with micro nutrients, Zn and Mn, on rice. The experiments were conducted using completely-randomized block design with six treatments and three replications. The treatments were P = Tithonia Organic Fertilizer Plus (TOFP) + 3.0 kg Mn.ha-1, Q = TOFP + 3.0 kg Mn.ha-1+ 3.0 kg Zn.ha-1, R = TOFP + 4.5 kg Mn.ha-1 + 6 kg Zn.ha-1, S= TOFP + 4.5 kg Mn.ha-1+ 9 kg Zn.ha-1, T = TOFP only, U = 100% chemical fertilizer only. Treatment with micro nutrients as addition to TOFP (TOFP+ 3.0 kg Mn.ha-1 and TOFP+ 3.0 kg Mn.ha-1+3.0 kg Zn.ha-1) increased rice grain yield by 80 g per clump.

Rice (Oryza sativa L.) is an important food crop that is the staple food of more than half of the world's population because it contains nutrients that the body needs. Information on the genetic diversity of local rice scattered in the Kuantan Singingi Regency is still not available. Due to this fact, the genetic diversity of local rice can be identified by DNA analysis. A DNA-based molecular marker that can be applied as a plant genetic marker is SRAP. The SRAP (Sequence Related Amplified Polymorphism) marker system is one of the powerful molecular tools for the clarification of individual sex and estimating the genetic diversity of plant species. This study aims to determine the genetic relationship of rice plants in the Kuantan Singingi Regency through SRAP markers. Twenty-four (24) local genotype samples were used in this study. Observational data were processed using Ms. software. Excel and (NTSYS-pc) version 2.02. The results obtained 17 fragments in Primer M, which resulted in a similarity analysis between 71% to 100%. There are two (2) groups at 75% similarity, then there are five (5) groups at 81% similarity and there are four (4) groups that have 100% similarity. The results of this study are expected to be taken into consideration in developing rice breeding strategies in the future.

Application of system of rice intensification (SRI) method has been considered as one of powerful efforts to increase the harvested yield by modifying the plant and itssurrounding environment. This study was aimed to determine the effect of different environment towards the response of rice varieties grown using SRI method. Two rice varieties, Batang Piaman and IR-42 were grown in District of Tanjuang Barulak (Regency of Tanah Datar) and District of Saniang Baka (Regency of Solok). Plant height and several yield parameters, such as productive tillers, panicle length, grain number per panicle, and yield per plot were assessed from both varieties and locations. Statistical analysis was conducted using randomized block design (RDB) and significance was further evaluatedusingDuncan’s New Multiple Range Test (DNMRT) with a p>0.05. Batang Pariaman appeared in taller performance than IR-42. Regarding the number of productive tiller, Batang Piaman resulted more productive tillers in Solok, while IR-42 was dominant in number of productive tiller compared to Batang Piaman in Tanah Datar. Unlike IR-42, Batang Piaman exhibited longer panicle, more grain amounts per panicle, and higher yield per plot than IR-42 in both locations.

Population growth rates cause an increase in food demand, but the planting area is decreasing due to land-use change. The land available to be utilized by farmers is mostly suboptimal land. The disadvantages of suboptimal land are low pH values (4.7) and a small number of nutrients (Nitrogen = 0.11%, Phosphorus = 0.45 ppm, very low Carbon, very high Aluminum, and medium Cation exchange capacity) and for increasing the value of suboptimal land can be given organic fertilizer such as cattle manure and kieserite. This study aims to determine the effect of cattle manure and kieserite on rice growth with the SRI planting system in suboptimal land. The study was carried out in farmers' paddy fields at Ambacang Market, Kuranji District, Padang from June to October 2019. This experiment uses a completely randomized design (CRD). Data were analyzed by the F test at a 5% significance level. If it is significantly different, it is continued with the Honestly Significant Difference test (HSD) at the 5% significance level. The results showed that the application of cattle manure and kieserite can increase the height of rice plants and the number of tillers.

Penggunaan pupuk sintetik merupakan faktor penentu produksi terbesar, tetapi harganya makin mahal, sehingga menjadi masalah nasional. Oleh karenanya, pupuk alternatif harus ditemukan, salah satunya adalah POTP. Pupuk organik titonia plus (POTP) dapat mengurangi aplikasi pupuk sintetik hingga 50% dalam meningkatkan hasil padi pada sawah bukaan baru di Dharmasraya, serta sawah intensifikasi di Padang, Solok, dan di Tanah Datar. Akan tetapi, hasil padi pada sawah intensifikasi dengan POTP tersebut masih sekitar 6 ton/ha, pada hal hasil optimal yang diharapkan dengan POTP sekitar 8 ton/ha. Hal itu diduga akibat adanya gejala kekurangan unsur hara mikro. Unsur hara mikro apa yang diperlukan dalam pembuatan POTP belum diketahui. Tujuan penelitian ini adalah: untuk melengkapi formula POTP dengan unsur hara mikro untuk mengurangi aplikasi pupuk sintetik hingga 50% pada sawah intensifikasi dengan target hasil gabah sekitar 8 ton/ha. Hasil penelitian sebelumnya didapatkan 3 kombinasi Mn dan Zn yang ditambahkan dalam pembuatan POTP. Tiga formula POTP tersebut telah diteliti di lapangan pada dua lokasi sawah intensifikasi di kota Padang. Hasilnya formula POTP+3,0kgMn/ha+0kgZn/ha dan POTP+3,0kgMn/ha+3,0kgZn/ha dan POTP+4,5kgMn+6kgZn dapat diaplikasikan ke sawah, untuk diuji multi lokasi di kabupaten Solok dan Tanah Datar. Perlakuan yang dilakukan pada dua lokasi tersebut adalah POTP+3,0kgMn/ha+0kgZn/ha, POTP+3,0kgMn/ha+3,0kgZn/ha, POTP+4,5kgMn+6kgZn, POTP saja, dan 100% pupuk sinntetik. Rancangan yang digunakan berupa rancangan acak kelompok (RAK) dengan 3 kelompok. Hasil terbaik yang telah dilakukan pada sawah intensifikasi di Kabupaten Tanah Datar dan Solok adalah formula POTP+3kgMn/ha+3kgZn/ha serta POTP+3kgMn/ha+3kgZn/ha. Penambahan unsur mikro memberikan peningkatan hasil sebanyak 3,8 15%. Kata kunci: padi, unsur hara mikro, dan POTP
