Abstract
The freshwater swampland is one alternative as a source of food production in Indonesia because it is quite fertile and vast about 25.20 million ha. Several limitations of this area includes unpredictable water regime, floods in the rainy season, and drought in the dry season. The objective of this study is to evaluate new high yielding varieties and planting methods in the freshwater swampland. The experiments were carried out in the freshwater swampland of the Alabio polder area, Teluk Cati Village, Hulu Sungai Utara Regency covering an area of 5 ha, in the dry season in 2013 and 2014. In 2013 there were two kinds of treatment: first planting method (2:1 and 4:1) and varieties (Ciherang, Inpari-1, Inpari-17, and Inpari-19). In 2014, the treatment were varities (Ciherang, Inpari-1, Inpari-17 and Inpari-30) and planted by jajar legowo planting 4:1. The treatments were implemented by randomized block design with 10 replication. This study indicates that high-yielding varieties can increase rice productivity and farmer income. Rice productivity in the two growing seasons ranges from 4.46 to 7.12 t ha-1 dry grain. In the dry season of 2013, the Inpari-17 variety showed higher yields than the Inpari-1, Inpari-9, and Ciherang varieties. In the dry season of 2014, the results of Inpari-30, Inpari-17, and Inpari-1 were higher than that of Ciherang. Rice farming on freshwater swampland is immensely profitable (RC-1 3.09 and 2.78) and worth cultivating (BC-1 2.09 and 1.78).
