Assessment of the impact of climate variability on Sesamum indicum L production in Gimbi district west Wollega Ethiopia

Abstract

This research aimed to understand the impact of climatic variability on sesame yield, plant growth, and rainfall and temperature changes in Gimbi District over the past 30 years. Data was collected through surveys and analyzed using tables and percentages. The study found that temperature is increasing annually, with an average maximum temperature of 260 degrees Celsius and a range of 270 degrees Celsius. The 176 farmers in the study region were selected using a random sample procedure. The study reveals a positive correlation between maximum temperature and sesame output, with a 100% positive correlation. However, a negative correlation exists between sesame and minimum temperature, indicating a drop in production as temperatures drop. A complete positive correlation (.127) exists between average temperature and sesame, indicating a strong relationship between the two variables. The shattering problem is the largest loss of produce when the wet season is prolonged at harvesting time. Late sowing and sufficient human work are the best ways to avoid this issue. Sesame production was significantly related to extreme weather events, average temperature, precipitation, and minimum and maximum temperatures. Maximizing sesame output in the research region requires examining additional variables such as humidity, snowfall, fertiliser, and other soil components.
