Evaluation of Several Superior Rice Varieties on Yield and Seed Production in North Sumatra

Abstract

The evaluation of several superior rice varieties on seed production and yield in North Sumatra aims to evaluate superior varieties that are adaptable and high-yielding, as well as produce quality seeds in North Sumatra to support the sustainability of certified rice seeds. The research was conducted in the IP2TP Pasar Miring from October 2021 to January 2022. The experimental design was a randomized block design with 3 (three) replications and 10 tested varieties (Ciherang, Mekongga, Cibogo, Inpari 16, Inpari 30, Inpari 32, Inpari 42, Inpari 43, Inpari 44, inpari 48, and Inpari Nutrizinc). The soil was perfectly cultivated, and the planting system was legowo 2:1, the spacing was 30 cm between rows, 15 cm within rows and 50 cm between rows (legowo). Among the ten varieties studied, Inpari 32 (6,159.00 kg/ha), Ciherang (5,738.67 kg/ha), and Mekongga (5,625.00 kg/ha) have the highest yields. Meanwhile, most seeds were produced by Inpari 32, which produced 4,575 tons/ha, followed by Ciherang (4,378 tons/ha) and Mekongga (4,073 tons/ha). Seed producers must pay attention to the market when producing seeds, which are seeds that are widely developed at the farmer level or varieties that consumers, both traders and farmers prefer.
