dc.description.abstractA study was conducted to evaluate the response of rice to P and P use efficiency from MPR, Minjingu mazao and TSP fertilizers under irrigated rice (Oryza sativa L.) production in Lekitatu village. The fertility status of the soils and their suitability for rice production at two experimental sites were evaluated based on technical indicators of soil fertility. The major soil fertility limitations included low soil organic matter, low total nitrogen and medium available phosphorus hence the rice soils in Lekitatu village were categorized as of low fertility status and moderately suitable for rice production. Phosphorus was applied at rates of 0, 20, 40 and 60 kg P ha’1 as MPR, Minjingu mazao and TSP. Nitrogen was applied uniformly at a rate of 60 kg N ha’1 as urea to the MPR, Minjingu mazao and TSP treatments plots taking into account the 10% N contained in the Minjingu mazao fertilizer. The P fertilizers were broadcasted and incorporated into the soils before transplanting the rice seedlings and N was applied at two equal splits, namely at tillering and panicle initiation stages. The ranges in yield components between the control (0 kg P ha’1) and the highest levels of P (60 kg P ha’1) were 12-22, 12-19 and 12- 22 number of tillers per plant, 7.67-25.97, 7.67-26.83 and 7.67-30.20 tha’1 dry matter yields and 1.5-8.63, 1.5-9.23 and 1.5-10.43 tha’1 grain yields for MPR, TSP and
