Abstract: Rice is one of the most important food commodities in Indonesia because it is the staple food of most of the population. However, until now the rice crop productivity is low and has not fulfilled the overall needs. Therefore, efforts are needed to increase yields of rice plants. One effort to do this is by providing nutrient silica (Si) on rice cultivation. To reduce costs, given the element Si was isolated from rice husks are made in nano size. This study aims to know the influence of nutrient in the nano-size Si on the growth of rice plants. Treatments include: (1) The type and dose of fertilizer is fertilizer Ordinary Silica (OS) in the form of fertilizer SiP with normal particle size, concentration 0.9, 1.8, 2.7, 3.6 and 4.5 ppm and Nano-Silica (NS) concentration 0.09, 0.23, 0.45, 0.68 and 0.9 ppm and (2) Rice varieties, namely paddy rice IR 64, Ciherang and upland rice Situ Bagendit, Situ Patenggang. Based on the results of the study concluded that the granting of nano-silica treatment gives a better effect than ordinary silica fertilizer application (SiP) and controls at all observation variables such as plant height, root length, leaf length, canopy and root fresh weight and dry weight of canopy and root.
