Rice (Oryza sativa L.) is the world leading cereal crop for human utilization, with cultivated area of almost 150 million hectares and a total production of almost 600 million mega grams annually. The cultivation of rice in Ethiopia is of more recent history than its utilization as a food crop. The production and productivity of the crop under farmers’ field conditions is low (about 2600 kg of rice grain ha−1 on the average) compared to its yield levels under farmers’ conditions in other parts of the world due to low soil fertility. Therefore, experiment was conducted at Tole village, Gimbi District, West Wollega, Oromia, Ethiopia from June - December during the main rainy season of 2019. The experiment consisted of factorial combination of four levels of blended fertilizer (0, 100,150 and 200kgha-1) and four level of nitrogen fertilizer (0, 46, 69, and 92kgha-1) which was laid out in a randomized complete block design with three replications. The data was recorded on phenology, growth and yield related parameters of the crop. The results had shown that the main effects of rates of blended fertilizer and nitrogen were significant (P < 0.01) difference on different growth parameters, yield and yield components of rice. There were significant interaction effect on rates of blended fertilizer and nitrogen on days to heading, days to maturity and grain filling period. Earliest days to heading and maturity were recorded by the interaction of no blended and no nitrogen fertilizer, whereas latest days to heading and maturity was recorded at 200kgh-1BF and 200kgha-1Urea. The maximum grain yield was obtained as fertilizer rates increased. However, the partial budget analysis indicated that application of 100kg of BF ha-1 and 46kg of N fertilizer resulted higher marginal rates of return (1,781% and 823.1%) respectively. It could, thus, concluded that application of 100kgBF ha-1 and 100kg Nha1 resulted in optimum growth and grain yield of the crop. Hence, application of inorganic fertilizer for the production of rice resulted the highest yield and benefits for the growers in the study area, but further study is needed in the future for recommendation.
