The development of nanotechnology has been an emerging multidisciplinary field that can have vast potential impact on the society specifically in the areas of agriculture. Nanofertilizers have been known to have a slow and steady release of nutrients needed by the plant and therefore reduce the loss of nutrients and improve nutrient use efficiency. A research was conducted to investigate the effect of different rates of FertiGroe nanofertilizers N, P and K on the growth and yield of corn during dry season. The agronomic and physiological parameters measured indicated that plants applied with 50% optimization rate (OR) have significant effect on days to emergence, days to tasseling, days to silking, stalk diameter, leaf length, plant height, dry matter yield and biological yield. Based on the data obtained, plants applied with 50% OR FertiGroe N, P and K showed significant difference compared with other treatments. Other treatments applied with fertilizer higher than 50% OR showed negative effects. In fact, stunted growth was also observed probably due to toxicity effect of excessive nutrients. The resulting yield of the different treatments is significant different from the control but not significant different from each other. Thus, it is suggested to not use higher fertilizer rates than the recommended and conduct and experiment for another season to further support the claims on this study and recommended a final rate to attain best potential yield of corn.
