Emergence of Phyllochron of 3 Rice Varieties in Different time of Land Flooding in System of Rice Intensification (SRI)

System of rice intensification (SRI) is a method of rice cultivation which has proven to increase the rice yield if comparing to the conventional method. The research aimed to study the influence of flooding of land to phyllochron emergence and tiller of rice plant. The research was conducted in farmer field in Koto Tangah, Padang from May-June 2018. Randomized block design in split-plot was used in this research. The main plot was the inundation time before planting in 7, 14, 21 and 28 days. Three replications were used in this research. The subplot was the three rice varieties, Pandan Wangi, PB 42 and Kuranji 012. The result showed that variety PB 042 and Kuranji 012 in 14 days of inundation were the best variety with the amounts of tillers were 40.
