Abstract

Rice plant (Oryza sativa L.) is one of important food crops that will always be cultivated and developed in producing the main food for people of Indonesia. The experiment aiming to know effect of organik manure and micro nutrient on storability vigor (SV) of seeds of two rice varieties had been conducted during July 2009 to January 2010. Three treatments were arranged factorially within a split-split plot design with three replicates. The organic manure of 0 ton/ha (as control) and 2 ton/ha were applied as main plots, the micro nutirent of 0 (as control), 1, and 2 kg/ha were applied as subplots, and two varieties of Mira and Mayang were applied as sub-subplots. The storability vigor of seeds was measured using a chemical rapid ageing method with saturated ethanol vapour (CRAM). Intensity of ageing used were 0, 10, 20, 30, 40, and 50 minutes. The seeds used in each replicate were 50 seeds. Variable observed in this experiment was the slope value (b) of each linear curves of SV that derivated from each variable of seed viability. Those were percent of total normal seedling (TNS), strong normal seedling (SNS), percent of abnormal seedlings (ANS), and dry weight of normal seedling (DWNS). The SV curves of straight line Y = a ± b X were built from the values of seed viability as Y axis and ageing intensity as X axis. Then, the data of slope (b) values of SV curves were analyzed using analysis of variance at 5% level of significance. Tukey's test, at 5% level of significance, was used to comparing mean value among the treatments. Results show that storability vigor of seed was affected by orgnic manure and micronutrient, and between organic manure and varieties. Combining between organic manure of 2 ton/ha and micronutrient of 1 kg/ha could produce rice seeds with the highest storability vigor of seed. The storability vigor of Mira seeds was higher than of Mayang seeds. The storability vigor of seed of Mira variety was higher than those of the Mayang. Key word: manure, micro nutrient, organic, rice, storability vigor.
