Abstract
Plant probiotic soil amendment is claimed significantly improved nutrient absorption due to more developed plant roots. This study was carried out at the Faculty of Sustainable Agriculture, Universiti Malaysia Sabah from June 2016 until November 2016 to investigate the effect of plant probiotic (0.0, 3.0, 5.0, and 7 .0 g/25L water) on growth and yield of rice variety TR-8 and MRIA-1 for wetland rice and aerobic rice, respectively. Treatment were arranged using Complete Randomized Design (CRD) with four replications. Data collected were analysed using two-way ANOVA at 5% significance level and mean was separated by Duncan's Multiple Range Test (DMRT). The results showed that vegetative growth of rice plants, treatment P3 produced the highest mean plant height among all the treatments (105.3cm) for MRIA-1 and treatment P4 forTR-8 which was 86.37cm. Treatment P3 had the highest number of tillers (23) while treatment P4 had the highest percentage of productive tillers (85.94%) for MRIA-1, while for TR-8, treatment P4 had the highest number of tillers (44) while treatment P2 had the highest percentage of productive tillers (60.08% ). In terms of moisture content, treatment P3 and P4 showed the higher moisture content of rice MRIA-1 (55.06%) and TR-8 (32.82%) compared to other treatments. For shoot:root ratio, treatment Pl showed the highest ratio for both treatments that revealed the roots obtained more nutrients and well developed than shoot. For yield component of rice plant, treatment P3 produced the highest number of spikelets per panicle (214) for MRIA-1 rice variety and treatment P2 (320)for TR-8 rice variety. For analysis for pH value of soil, treatment P3 had the highest pH value for both rice variety. Best performance was obtained as follows: aerobic rice, MRIA-1, with treatment P3 (Sg/25L water) increase 122% in panicle number compared to other treatments while 92% increase in panicle number for TR-8 with treatment P2 (3g/2SL water). Thus, it can be recommended that the treatment P3 and P2 is the best rate to be recommended to farmers for MRIA-1 and TR-8, respectively, because they produce the highest yield components.
