    EFFECTS OF RAINFALL VARIABILITY ON CASSAVA PRODUCTION IN LAFIA LOCAL GOVERNMENT AREA OF NASARAWA STATE, NIGERIA
    (DEPARTMENT OF GEOGRAPHY FACULTY OF ENVIRONMENTAL SCIENCES NASARAWA STATE UNIVERSITY, KEFFI, 2019-04-09) Bulus, Alidu Denis
    Rainfall variability is a threat to crop production and food security in the tropical environment. When there is a wide deviation from the long term average rainfall of an area, crop production may be adversely affected. This study therefore examined the effects of rainfall variability on cassava production in Lafia Local Government Area of Nasarawa State, Nigeria, from 2000 - 2017. The objectives of the study were to examine the trend of rainfall received, determine the trend in cassava production and the relationship between rainfall received and cassava production in the study area during the period. The data on rainfall and cassava production were collected from Nigerian Meteorological Agency and Nasarawa Agricultural Development Programme, Lafia respectively. The study employed the use of statistical techniques such as Time Series Trend Analysis for the rainfall and cassava production and the Pearson Product Moment Correlation Coefficient to determine the relationship between rainfall variability and cassava production. The study showed that the rainfall trend in the study area has been increasing during the period, with the coefficient of variation of50.63% and annual mean rainfall of 3190mm. The time series trend of cassava production on the other hand showed a positive increasing trend. The correlation analysis on rainfall variability and cassava production showed a strong positive linear relationship of 0.711 between both variables. This implies that cassava production is highly dependent on rainfall. With the results obtained, the study recommended that a hybrid cassava variety that can easily adapt to the rainfall variability trend in the study area should be developed and that farmers should begin their planting of cassava in the month of April, which marks the proper onset of rainfall in the study area.
