TREND ANALYSIS OF AGROCLIMATIC PARAMETERS AND CROP YIELDS IN SOKOTO STATE NORTHWEST NIGERIA

Abstract

This study examined the trends and variability of climate parameters and crop yields in Sokoto State, 
northwest Nigeria, recognizing the importance of climate in agricultural production. Secondary data on 
temperature, precipitation, humidity, solar radiation, and wind speed were obtained from NASA archives, 
while crop yield data for maize, millet, rice, and sorghum were sourced from national agricultural 
databases including NAERLS, NFRA, and NBS. Trend analysis was employed to assess trends and 
patterns over the 15-year period. Results revealed positive trends with intermittent fluctuations across all 
climate parameters, projected to persist in the near future. Maize, millet, and sorghum showed increasing 
yield trends, whereas rice exhibited a slight decline during the study period. Owing to fluctuations 
observed, the study concludes that continuous monitoring of climatic variables and adaptive crop 
management strategies are essential for sustainable agricultural development. It recommends integrating 
climate-smart agriculture and long-term planning frameworks to enhance resilience and ensure food 
security in the region.
