Abstract

The study focused on trend analysis of climate parameters (Rainfall, Temperature and Relative humidity) viewed across years of crop production in the Ogoja, Cross River State, Nigeria. The purpose of the study was to examine the trend pattern of climate parameters in relation to crop production over thirty years of period. The study adopted the use of participatory research method in addition to data obtained from Nigeria meteorological Agency (NIMET) Ogoja. Hypothesis was tested using regression analysis. The result of regression analysis revealed that there is a significant relationship between climate parameters (rainfall, temperature and relative humidity) and years at 0.05 level of significance. This implies that the area experience heavy amount of rainfall from year to year, but the uncertainty in the rainfall pattern (timing and amount) at the study area influenced crop production. Temperature has significant positive relationship with time. Normally, increase in temperature should have positive impact on crop yield in the tropical or near tropical zone, because normal high temperature enhances high rates of bio-chemical reaction in plants. Therefore significant increase in temperature may result in accelerated physiological development, leading to increase yield and maturation. The study recommends the cultivation of crops with natural adjustment potentials to climate oscillations
