Effect of effective microorganism (EM) application at different phenology on aerobic paddy Cv. Mria 1 / Siti Wardatul Laily Che Hamid

This research was conducted to evaluate the effect of EM application at different phenology of aerobic rice cv. MRIA 1. The objective of this research was to determine the effect of EM application at different phenology on growth and yield component on MRIA 1. This experiment was carried out by using CRD experimental design consisted of three treatments with two replications. Aerobic seed variety of MRIA 1 was obtained from MARDI used as planting materials and has been applied by three different treatments of EM during different phenology. The first treatment (T1) as a control, applied with recommended chemical fertilizer (normal practices) with 1.8g NPK + 0.9g Urea with no additional of EM was applied on seedling stage (17 DAS). Second treatment (T2) consisted of 1.8g NPK + 0.9g Urea + 200 ml EM solution applied on vegetative stage (30 DAS) and third treatment (T3) was treated with 0.9 g NPK + 0.9g Urea + 200 ml EM solution applied on reproductive stage (50 DAS). Plant growth parameters were collected at five series of harvesting at 40, 60, 74, 88, 102 DAS. Result shown that there were no significant differences between treatments for parameters studied (shoot and dry weight, SPAD value and number of tiller and panicle). The result shown that the patterns are more rapid on T1. Application of T1 showed that the highest increment of shoot dry weight (4.3335 g), root dry weight (1.878 g), numbers of panicle (22.5/pot) and numbers of tiller (6.1/pot). However, T2 obtained the highest value in mean SPAD for 5 series harvesting (H1:38.62, H2:40.19, H3:36.23, H4:48.49 and H5:38.85 nmol). But there were significant different on between each of treatment on fill seed/pot (g). Where the T1 have the higher value (1.6125 g). As a conclusion, application of EM on different phenology growth was not improved plant growth parameter and yield component of aerobic rice cultivation.
