Impact of climate variability on rain-fed maize and sorghum yield among smallholder farmers

چکیده
Rain-fed food crop production is very sensitive to climate variability. The majority of Ethiopian population reliant on rain-fed seasonal agriculture, which the backbone country’s economy. objective study was investigate impact rainfall and temperature changes maize sorghum yields. data were analyzed using Mann–Kendall trend test, Sen’s slope, correlation, regression models. study’s findings demonstrated that have different effects Mann-Kendall test has detected presence a significant increasing for both Though there an upward trend, result also suggests yields been fluctuating more. There variation 90% 88% in yield, respectively. R-squared statistics indicated variability 25.21%, 1.12%, 20.39% yield explained by its growing period rainfall, minimum, maximum Growing minimum positively correlated with output, while negatively correlated. A association between temperature. model revealed temperatures 46.81%, 5.08%, 30.18% production, Both crops showed unpredictability as changes, emphasizing necessity irrigated agricultural diversification, livelihood diversification respond

The 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 ...

Nitrogen management strategies for smallholder maize production systems: Yield and profitability variability
Maize (Zea mays L.) production requires large amounts of nitrogen (N) thatdirectly affect production cost. Poultry litter can be used as an alternative source ofN. To optimize its use, poultry litter requires technical and economic feasibilityanalyses. Crop simulation models have proven to be efficient tools to support thistype of research. The objectives of this study were to determine yield a...
