Adaptation Test of 3 Rice Strains (Oryza Sativa L.) By Using Two Comparison Varieties, Inpari 35 and Mekongga in Salin Land, Bokem Village, Merauke District

Abstract

The purpose of this study was to analyze the adaptation or adaptation of the 3 (three) rice lines tested with 2 (two) control varieties on saline soils in Kampung Bokem. The use of tolerant varieties is one of the most effective ways to exploit the potential of saline soils in an effort to increase national rice production. The area of saline land in Asia is around 21.5 million ha, of which 12 million ha are saline and 9.5 million ha are alkaline. This research was carried out using a randomized block design (RBD), using 5 (five) treatments and repeated 4 times so that 20 experimental units were obtained. Based on the results of the study, there were no strains that died due to salinity stress. This indicated that all of the lines included in this experiment were considered to be quite tolerant to salinity. The best growth line is line 10 with a number of productive tillers of 20.03 stems and the best production is line 5 with a production of 4.75 tonnes/ha.
