Abstract
In fact food security can be increased through improved land use and land management practices. In Ethiopia much of the increase in crop production in the past decade has been due to increases in area of cultivated. To what extent expansion can continue remains a question, therefore obtaining higher yield rates is the challenge of Ethiopia’s agricultural system. Conservation agriculture (mulching); which here refers to minimizing soil disturbance through no-till practice, application of organic mulch cover, and cropping in time; has the potential to improve soil quality, water, and crop productivity. The objectives of this critical review is to collect available information in similar production environments, indicators on the essential of CA contributions to soil quality, crop and water productivity both in dry and rainfall seasons of Ethiopian agriculture. Recently a study on the role of conservation agriculture indicates improve soil quality, crop yield and water productivity. In addition to this CA can be protect soil layer for erosions either wind or runoff, to optimize infiltration rate minimize runoff, to crate the path of soil it contributes micro nutrients move easily. So, reviewer concluded that conservation agriculture is potentially important to improve sustainable Ethiopian agricultural production and productivity. This agricultural practice (CA) should be able to adopt for irrigated and rain fed farms of Ethiopia.

Summary
Food security can be increased through improved land use and land management practices (Branca et al, 2013; van der Molen, 2017; Ramankutty et al, 2018), Agriculture in the decade will have to produce more food on less land (Hobbs, 2007; Hobbs et al, 2008; Govers et al, 2017) and purchased production inputs by making more efficient use of natural and applied resources but with a minimal negative impact on the environment (Stagnari et al, 2009; Meemken and Qaim, 2018; Baylis et al, 2021). This review pepper was troubled to conservation agriculture (CA); which here refers to minimizing soil disturbance through no-till practice, application of organic mulch cover, and cropping in time; has the potential to improve soil quality, water, and crop productivity. History of Agricultural practice in Ethiopia The history of tillage dates back many millennia when humans changed from hunting and gathering to more sedentary and settled agriculture mostly in the Tigris, Euphrates, Nile, Yangste and Indus river valleys (Hillel, 1991) as cited by (Hobbs et al, 2008) From those Ethiopia is the source of Blue Nile the agriculture is generally dominated by smallholder, rain-fed, low-input-low-output mode of production (Agerie, 2013) Since, Ethiopian farmers have been practicing excessive soil tillage using animal traction for thousands of years (Goe, 1987) as cited by (Getnet et al, 2015).
