Discovery Agriculture, 7(17), 26-362347–3819e-2347–386Xhttps://repository.futo.edu.ng/handle/20.500.14562/1481This article contain tables and figureA field experiment was conducted from December, 2017 to April, 2018 dry seasons at the Center for Agricultural Research and Extension, Federal University of Technology, Owerri, to determine the effect of different rates of Pig slurry on a degraded sandy soil and the yield of Upland Rice (Oryza sativa). There were 6 treatments namely T1 (Control), T2 (NPK 20:10:10) at 800 kg.ha-1, T3(10t/ha of pig slurry), T4 (20t/ha of pig slurry), T5 (30t/ha of pig slurry), T6 (40t/ha of pig slurry) and replicated 3 times. Each plot measured 2 m X 2 m with a 1 m alley between plots. Pre harvest and post harvest soil samples were collected from the sites at 0-30cm depth and used for the determination of selected physical and chemical properties. Grain yield was adjusting to 12 % moisture content and weighed. The experiment was mapped out according to Randomized Complete Block Design. The data generated was subjected to analysis of variance (ANOVA) and significant means were separated using Fishers Least Significant Difference at P = 0.05.The soil properties and grain yield of rice were not significantly affected when T1 (control) was compared with T2 (NPK) treatments. While the application of different rates of Pig Slurry when compared with the control and NPK rates revealed significant effects on soil properties and grain yield of rice. Grain yield increased with increase in rates of pig slurry application. Rice grown on plots treated with 40 t.ha-1 pig slurry gave the highest grain yield as it showed 95, 90, 85, 40, and 20% higher yield when compared with rice yield from the control, NPK, 10 t.ha-1, 20 t.ha-1 and 30 t.ha-1 plots respectively. Pig slurry application rate at 40t.ha-1 has proved to be a good rate for rice production with a promise that increasing the rate beyond this level may continue to give economic yield on a degraded sandy soil.enAttribution-NonCommercial-ShareAlike 4.0 InternationalRates of pig slurrydegradedirrigatedsandy soilyieldupland riceDepartment of Soil Science and TechnologyArticle
