Food grain yield response to climate variability in Nigeria: an empirical analysis

Abstract

The effect of variability of climate parameters on grain yield and the proportion of change in production that is due to impact of climate variability demands urgent attention. This study looks at the consequences of climate variability on grain yield in Nigeria within 1970-2012.The result revealed that the yield of rice was negatively affected by rainfall (p=0.1) and (p=0.05) for fertilizer quantity. Maize yield was observed to be influenced negatively by area harvested (p=0.1). Based on these findings, the use of improved high yielding varieties, availability of more input supplies, introduction of improved farming techniques and cultural practices are necessary to increase the yield of these grains.

Keywords: climate variability, yield and grain, cultural practices
