Field experiments were conducted at the research field of the National Cereals Research Institute, Badeggi, Niger State, Nigeria (Lat. 9° 45' N, Long.06° 07' E). The experiments were designed as 5 x 4 factorial in Randomized Complete Block and laid out in split-plots arrangement, replicated three times. Results showed that the application of different combinations of organic manure and inorganic fertilizer resulted in significantly better growth and grain yield (2.51 t/ha for 1 t/ha + 20 kg N/ha urea and 2.26 t/ha for 0.5 t/ha + 40 kg N/ha urea), compared to the none application of any form of soil amendment (control) (1.38 t/ha), with the parameters also varying significantly among the soil amendments. The use of combined organic manure and inorganic fertilizer, more importantly, 1 t/ha PM + 20 kg N/ha and the cultivation of the NERICA 1 rice variety, are hereby recommended for the farmers in the experimental area.
