“…The causes poor growth and development of plants, especially sensitive varieties against at nutrient stress (Noor et al, 2012). Utama et al, (2012) The high solubility of Fe, which reached 104.69 mg kg -1 and the low availability of nutrients for plants (Table 1), affecting the growth and development of all brown rice varieties cultivated in these experiments, it can be seen in all parameters of observation (Table 2, 3 and 4). The presence of interactions between the two treatment factors, namely: rice varieties with plant growth regulator (PGR), all parameters were observed, an indication of the different tolerance of each of the brown rice varieties to stress ferrous.…”

The aim of this experiment was to increasing production and iron content of the brown rice, through the biofortification program in paddy fields gripped the iron. The experiment was conducted in the Sub-District of Koto Baru, Dharmasraya, from March to July 2015. The purpose of the experiment is to produce, grain brown rice super high levels of iron, and increased production of brown rice. Methods of bio-fortification with iron in biofortification method in the fields of ferro gripped, by utilizing the technology package can increase production paddy cultivation reached 5.1 Mg ha -1 with the iron levels of 25.6 mg kg -1 Inpari 24.Brown rice tolerant varieties (Inpari 24) + Ameliorant cow manure 10 Mg ha -1 + System of square utama [(7.5 × 7.5 cm) × 25 cm × (7.5 × 7.5 cm)] + One seedling per planting point, age 10 day + plant growth regulators, auxin 5ml liter -1 can be used to achieve the growth and production of the best for brown rice varieties cultivation on paddy fields gripped Fe, especially in Koto Baru, District of Dharmasraya.

“…This is presumably because the levels of ion ferrous high and low soil fertility (Audebert and Sahrawat. 2000;Utama et al, 2012), will lead to poor growth and development of plants, (Ma, 2000;Rengel, 2000), especially on varieties sensitive (Haryoko et al, 2012).…”

“…High iron content as a result of irrigating wetlands causes reduction of Fe 3+ to Fe 2+ which causes poisoning. Another problem, which often arises is the low level of soil fertility due to nutrient binding by heavy metals [30]. Rice fields that experience iron poisoning, will cause delays in plant growth and development, especially in sensitive varieties.…”

Increased production, many face increasingly complex challenges. The problem, which is not less important is the limited rice varieties tolerant to iron stress. The aim of the study was to obtain growth and distribution patterns of Fe2+ ions in several hybrid rice varieties. Experiment in Koto Baru, Sitiung I, Dharmasraya Regency, West Sumatra. The experiment used a completely randomized design, with five replications. The single factor is rice varieties, namely: Mekongga, Inpari 24, Inpari 27 and Inpari 28. The paddy fields used contain 104.69 mg kg-1 Fe2+, these concentrations greatly affect growth which causes poisoning. The production of milled dry grain in all varieties remained high even though it was iron-strapped, because the number of productive tillers formed in the SBSU system was more than 21 stems per clump, with production of grain weight > 5.4 Mg ha-1. The pattern of iron distribution occurs through absorption and translocation in the vegetative and generative phases to roots, stems, leaves, grain, and rice. The difference in iron levels in each part shows the ability of each variety to adapt. To obtain rice grains rich in iron and able to grow and produce well in iron-clamped conditions, it is recommended that aquaculture using the SBSU system with Inpari 27 varieties be able to produce iron content in rice grains of more than 27 mg kg-1 with production of grain weight 6.83 Mg ha-1.
