Effect of Climatic Variability on Maize Production in Nigeria
نویسنده
چکیده
The study examines the changes in climatic elements and agronomic parameter (maize hectarage and output) for maize production in different ecological zones of Nigeria from 1980 2002. The study also evaluated the degree of variability in these parameters. To achieve these objectives, secondary data on climatic elements and agronomic parameters for 22years were analysed using two – way Analysis of Variance (ANOVA) and Coefficient of Variation. The result revealed significant differences in average annual rainfall, temperature, maize hectarage and output in the seven identified ecological zones (p<0.05). Less variability was shown by annual temperature and rainfall over the years. Annual maize hectarage and output exhibited high variability in the ecological zones. Development of irrigation facilities and adoption of cultivation method that will reduce exposure of soil to flood and erosion among others are recommended for savannah and forest zones respectively.

Impact of spatial-temporal variations of climatic variables on summer maize yield in North China Plain
Summer maize (Zea mays L.) is one of the dominant crops in the North China Plain (NCP). Its growth is greatly influenced by the spatial-temporal variation of climatic variables, especially solar radiation, temperature and rainfall. The WOFOST (version 7.1) model was applied to evaluate the impact of climatic variability on summer maize yields using historical meteorological data from 1961 to 20...

متن کاملThe Impact of Climate Change on Grain Yield and Yield Variability in Iran
In this paper, we have examined the effect of climate variables on the yield average and variability of major grain crops (rice, maize, and wheat) in Iran from 1983 to 2014. For this purpose, we made use of the Just and Pope Production Function crop yields panel data. The results revealed that the influences of climate variables were different in the crops. The time trend positively influenced ...
