This paper examines the determinants of CA technology practice on major crop productivityrnamong small holder farmers in Amhara region East Gojjam zone Gozamin woreda atrn(Yenebirina and Chimbord) kebele. The study was follow and employed mixed methodsrnresearch approach addressed by cross- sectional survey data since the study has been done atrnone season of time and place. The results indicate that sampled households are found inrndifferent categories of crop productivity with CA technology practice, i.e., medium yieldrnincrement of crop productivity (11.58 %), high increment of crop productivity (65.26 %) andrnhigher yield increment of crop productivity (23.16 %). The results of the ordered logit modelrnshow that some socio-economic and institutional factors affect the crop productivity underrnCA technology practice differently. Access to input, availability of mulch materials, age,rnlevel of education and percent of area of cultivated land covered under CA technologyrnpractice have significant positive influence on high and higher yield increment of major croprnproductivity category under CA technology practice.rnThe study shows CA extension advisory services is not included with multi discipline manner.rnThere was limitation of integration of CA technology with farm implement mechanization.rnThe study indicated that from the total cultivated land 38.58% covered under CA. Area ofrnland coverage under CA is low due to constraints of mulch materials. The study resultrnindicated among the three principles of CA technology practice (minimum soil disturbance,rncrop residue retention and crop rotations) farmers well practiced minimum soil disturbancernand crop rotation. However, crop residues retention or mulching is not well addressed due tornmulch material constraint.
