Analysis of Climate Variability and Trends for Climate-Resilient Maize Farming System in Major Agroecology Zones of Ethiopia

Maize is one of the most important cereal food crops, and it can be grown all year in various agroecological zones. However, its vegetative growth yield are susceptible to rainfall temperature variability. As a result, analysis variability trend was urgently needed maize-growing agroecology zones restructure production system. The aim study examine trends for developing climate-resilient maize farming system major northwest Ethiopia. implemented low productive (LPZ), medium (MPZ), high (HPZ) Ethiopia using daily time series climate data during period 1987–2018. coefficient variation (CV), precipitation concentration index (PCI), anomaly (RAI), standardized (SPI) were applied Mann–Kendall’s Sen’s slope estimator tests used detecting statistical significance changes temperature. Statistically significant increasing annual maximum minimum temperatures recorded maize-producing mean has exhibited warming 0.12 0.54°C per decade. average decreased by 38 67 mm decade Our research also showed that droughts now happen every three years; even consecutive seen 2009, 2010, 2011. For this reason, could required develop address issues both global sub-Saharan countries make up our area. Climate-resilient agronomic activities have been determined analyzing onset, length (LGP), cessation date. Accordingly, lower upper quartiles date onset range May 9 June 2, respectively; (LGP) rainy season ranges from 97 232 days, November 1. Therefore, short- long-maturing varieties planted 2 begin harvested first week under current climatic circumstances.
