%X The main obstacle to increase rice yield in new opening paddy fields, is that high levels of dissolved ferrous ions (Fe2+) which toxic to plants. This research aimed to study the growth and yield of several rice cultivars tolerant to Fe2+ in the new opening paddy fields with multi-packet technology. The experiment was conducted from April toDecember 2010, at the new opening pay fields in Koto Baru of Dharmasraya District, West Sumatra. Experiments used a factorial in a Completely Randomized Design with three replications. The first factor was, selected rice varieties which were: Krueng Aceh; IR 36; Tukad Balian; Ciherang; and Cisokan. The second factor was thedifferent plant spacing which were a 30 กม 30 cm with two seeds per hole, and Plant spacing (10 กม 10) กม 30 กม (10 กม 10)cm with one seed per hole. The rice cultivation with packet technology can improved the growth and yield of paddy rice cultivated in new opening paddy field high in Fe2+. Technology package consisting a combination of rice variety (Krueng Aceh, IR36, and Tukad Balian) + SRI system + peat amelioran 20 Mg ha-1 + plant spacing (10 กม 10)กม 30 กม (10 กม 10) cm with one seed per hole, had the best growth and yield of rice cultivated in the new opening fields high in Fe2+, especially in Koto Baru of Dharmasraya District, Krueng Aceh was a variety with the highest grain production by 5.65 Mg ha-1.
