Abstract
Rainfall is the vital ingredient and factor of soil nourishment on which crops are grown. The basic agricultural practices all over the world depend on rainfed cultivation for their sustainable development. This study focus on the rainfall trend between 2010 -2018 as it affects crop production in Keffi Nasarawa State, Nigeria. The time series analysis was conducted by using appropriate techniques of data collection and analysis. The linear integration model, quadratic trend model, growth curve model and regression analysis was applied to show the correlation between the rainfall and crop production in the study area. It was discovered that the period of rainy months have high correction and significantly fitted the model which indication high crop yields per harvest.
Highlights
1.1 Effects of Temperature and Rainfall Variability on Crop Production in NigeriaNigeria agriculture is almost entirely rain-fed which makes it intuitively susceptible to the vagaries of weather scientific evidence is overwhelming that there is climate change in Nigeria and its presents serious environmental risks and challenges demand urgent national response; that is, climatic fluctuation is putting Nigeria's agricultural system under serious threat and stress (Ayanlade et al, 2010)
In Nigeria it has been shown that rainfall patterns are highly variable from year to year
An examines the spatial-temporal dynamics of rainfall and temperature fluctuations in Nigeria over the last century and shows that the mean annual temperature has increased by about 0.04oc (Ayanlade et al, 2009)
Summary
Nigeria agriculture is almost entirely rain-fed which makes it intuitively susceptible to the vagaries of weather scientific evidence is overwhelming that there is climate change in Nigeria and its presents serious environmental risks and challenges demand urgent national response; that is, climatic fluctuation is putting Nigeria's agricultural system under serious threat and stress (Ayanlade et al, 2010). Temperature and precipitation (rainfall) are the climatic variables most critical to measure with regard to crop production systems This change in climate, according to tile report of Intergovernmental Panel on Climate Change can be caused by the natural process of volcanic eruptions, variations in the sun's intensity or very slow changes in ocean circulation or land surfaces which occur on time scales of decades, centuries or longer (Swart et al, 2003). Human activities are by far the major causes of climate change through the continuous release of greenhouse gases and aerosols into the atmosphere by changing land surfaces, and by depleting the stratosphere ozone layer This change in climate has the potentials of affecting all-natural systems thereby becoming a threat to human development and survival socially, politically and economically (Apata et al, 2009). Important rainfall indices crucial for agricultural activities in the tropics are the rainfall onsets, cessation and the length of the rainy season which is synonymous with the length of the growing season (LGS) (Oguntunde et al, 2012)
