Growth Response and Production of Rice (Oryza Sativa L.) Plant Study of Planting Distance and Concentration of Rice Husk Nanosilica Fertilizer

Rice is a food crop that is really needed by the Indonesian population as a staple food. The need for food continues to increase along with the increase in population. In facing obstacles in cultivation, efforts are needed to increase production with various technologies that provide sustainable benefits. The aim of the research is to study the response to rice growth and production with the application of plant spacing and application of rice husk nanosilica fertilizer. The experimental method used a factorial randomized block design. There are 2 types of treatment, namely plant spacing with 3 levels and fertilizer concentration with 3 levels, analysis using ANOVA and Duncan's test 5% and BNT 5%. The research results showed that there was a real interaction between planting distance and nanosilica fertilizer on the observation variable of plant height aged 20 after planting in the K3J2 treatment (60 ppm nanosilica concentration and 25x25 cm planting distance) and it was different from the others. In a single treatment, nanosilica had no significant effect on all treatments. At a planting distance of 30x30 cm, it produced the highest number of panicles, 18.99 panicles
