    Econometric Analysis of the Effects of Land Size on Cereals Production in Nigeria
    (Islamic University Multidisciplinary Journal, 2020) Akanni, Saheed B; Garba, Mohammed; Banjoko, Alabi; Afolayan, Razaq
    This study employed the techniques of unrestricted VAR to model and analyzed the causal effects of Land used for Cereals Production (LP) on Cereals Production (CP) in Nigeria for the period of 50 years (1966 to 2016). The data extracted from the repository of World Bank were used to obtain the time plots which depicted that the CP and LP series are not stationary at level. The unit root and cointegration tests carried out suggested that the series are integrated of order one I (1) and that the series are not co-integrated. This confirmed that the use of VAR(p) model was appropriate for analyzing the data. Based on the LR, FPE and AIC selection criteria, VAR (2) model was fitted to the data. Results from the fitted model estimates showed that both CP and LP series in immediate past periods t-1 (2015) and two previous periods t-2 (2014 and 2015) have significant impacts on CP series in current time period t (2016) while only LP in immediate past period t-1 (2015) has a significant effect on LP in current time period t (2016). The results of Granger causality test indicate a unidirectional relationship which runs from LP to CP. It is recommended that the Federal Government of Nigeria should re-visit the land tenure system policies and embrace those that will enhance easy acquisition of land by farmers for more cereals production.

    Modeling Effect of Some Factor that Contribute to Cereals Yields in Nigeria using Toda- Yamamoto Techniques
    (Sule Lamido University Journal of Science and Technology (SLUJST), 2020-06) Garba, Mohammed; Akanni, Saheed B; Yahya, Waheed Babatunde; Kareem, K. Y.; Afolayan, Razaq
    This study aimed to examine the direction of causality among Cereals Production (CP), Land used for Cereals Production (LP) and Cereal Yields (CY) in Nigeria for a period of 50 years (1966 to 2016) using techniques of Toda-Yamamoto. The maximum order of integration and optimal lag order of the series confirmed that VAR(2+1) model best fitted the data. Results from the estimated model revealed that two year past values t-2 (2014 and 2015) of CP is the major determinant of CP series in current time period t (2016) while one year past value t-1 (2015) of CY and two year past values t-2 (2014 and 2015) of CP and LP are major determinants of CY series in current time period t (2016).The results of Toda-Yamamoto causality examination showed that CY is Granger caused by both CP and LP. Based on the sequence of analyses carried out in this study, it was concluded that cereals yields in Nigeria can be predicted by both cereal production and the size of farmland used for planting cereal crops. The study then recommended that adequate plots of land be allocated to farmers interested in cereals production in order to improve yields of cereals and ensure food security in the country.
