Introduction of components of rice varieties technology in waterlogged land in Kendal Central Java

Abstract

Climate change can cause sea level rise and the expansion of rice fields affected by intrusion or seawater runoff. This problem is the adaptation of rice varieties that are tolerant of fresh or sea waterlogged in the farmers’ land. The location of the activities was in Brangsong Sub-Regency, Kendal Regency, Central Java, in 2018. A split-plot factorial experiment was designed with 3 factors, variety of paddy, ameliorants, waterlogged height. This study’s data analysis techniques are analysis of variance followed by standard real difference analysis and descriptive analysis. The observations of ubinan (rice harvesting tool) showed that Inpari 30 had the highest harvested dry grain productivity of 10 tons/ha in humic acid treatment in a 5 cm puddle. Meanwhile, the recommended varieties of Inpari 34 and Inpari 35 did not produce high productivity due to the easily collapsed cropping. Inpari 34 has a high percentage of filled grain, namely 90%.
