    Effect of Poultry Dung and Organomineral Fertilizer on the Growth of Maze
    (International Journal of Innovation and Scientific Research, 2015-09-11) Oladipupo, Olayinka
    This project is aimed at determining the effect of poultry dung and organomineral fertilizer on the growth of maize (plant height) at different stations (Apomu, Iwo and Jago). Response Surface Methodology, the first- order and the second- order models are used to determine the optimal plant height for given level of each of the variables or factors considered. Each location needs different requirement of fertilizer application, Apomu and Jago locations need the average of 83kg/ha of poultry-dung while Iwo location needs as much as 100kg/ha of organomineral to produce the optimum plant height.

    Estimating Inflation Rate And Money Demand In Nigeria Using The Generalized Polynomial Regression
    (iSTEAMS Multidisciplinary Cross-Border Conference, 2018-10-11) Oladipupo, Olayinka
    Inflation plays an important role in demand for money (M1). M1 is a function of inflation rate besides the rates of return of alternative assets and real income. The study aimed to empirically investigate the role of inflation on money demand function in Nigeria. The data collected was analysed using Polynomial regression. The quarterly time series data over the period from 1990:01 through 2017:04 was obtained from the Statistical Bulletin of the Central Bank of Nigeria (CBN) for monetary aggregates ( ), consumer price index and gross domestic product. Results of polynomial regression show that the relationship between inflation and demand on is nonlinear and represents a parabola. When the inflation rate increases above 3.64 percent, relationship between inflation and demand for will become negative. Results of polynomial regression model also shows that inflation is negative in relation to money demand; when the rate of inflation is above a critical level of inflation. Relationship between inflation and money demand follows the quadratic function. Demand for is only a function of rate of inflation and real income because treasury bills rate is statistically insignificant. During the high inflation period, inflation is negatively correlated with money demand. High money growth is consistent with high inflation, a low real money demand (high money velocity). In conclusion, empirical evidence suggests that money velocity is in general volatile, contradicting the assumption of a stable money demand.
