The Growth of Rice (Oryza Sativa L.) Ratoon System at Various Times Flooding Rice Stump from Conventional Cultivation and the System of Rice Intensification (SRI)

The research was carried out in the UPT of the experimental garden of the Faculty of Agriculture, Andalas University, in the form of using bucket media at an altitude of 350 MDPL from February to September 2017. The aim was to find out the best interaction when the flooding of conventional rice stumps and the System of Rice Intensification (SRI) was conducted. get good cultivation for the ratoon system and know the best flooding time for the growth of rice plants. To get good cultivation results for the ratoon system and find out the best flooding time for improving the ratoon system rice production. This study uses two-factor completely randomized design (CRD) of 3 replications. The first factor is the stump of cultivation (the origin of conventional cultivation stumps and the System of Rice Intensification (SRI)) and the second factor is the time to start flooding stump of 3 DAH (Day After Harvest), 6 DAH, 9 DAH, and 12 DAH. The data obtained were analyzed by variance with the F test and if the calculated F was large from the F table, it was continued with a 5% Honest Real Difference test. The results of observations that have been made, there is no interaction of conventional cutivation stumps and SRI method with various time flooding of the ratoon system rice growth
