ABSTRACT
A study was conducted to classify and establish the fertility status of the soil at the Dakawa Irrigation Scheme (DIS) and subsequent to this, a screen-house pot experiment was conducted to assess the response of rice (variety TXD 306) to nitrogen and phosphorus applied to the dominant soil type at the DIS. According to the Soil Taxonomy and the World Reference Base for Soil Resources, the soil of the study area classified as Inceptisol and Cambisol, respectively. Based on physical, chemical and biological properties of composite soil sample, the soil hadlow total N, low OC, organic matter and exchangeable Ca and Mg,and hence rated as marginally to moderately suitable for rice production. For the response of rice (variety TXD 306)to N and P, rates adopted were0, 50, 100, 150, 200 kgNha-1 and 0, 40, 80, 120, 160 kgPha-1 , respectively. The sources of N and P used were(NH4)2SO4) and (Ca(H2PO4)2), respectively applied in 5 2 factorial in CRBD. The number of tillers increased significantly (P < 0.05) with N and P levels from P0N0 kgha-1 to P80N200kgha-1 . Biomass weight (g) increased significantly (P < 0.05) from 10.99 g pot-1 to 93.04 g pot-1 at P0N0 kgha-1 and P160N200 kgha-1 , respectively. Grain yield(g) increased significantly (P
