The study was conducted during 2018 cropping season at Dugda Woreda to investigate the effect of in situ moisture conservation techniques on grain yield and yield components of maize. Treatments comprised of tied ridge, furrow closed at both end and farmer practice as control. The experiment was laid out in a randomized complete block design with 3 replications. The grain yield and 1000 seed weight were highly significantly (p<0.001) difference on tied ridge and furrow closed at both end as compared to farmer practices. But stand count and number of cobs at harvest per hectare and plant height were not significantly (p>0.05) difference on tied ridge, furrow closed at both end and farmer practice respectively. Tied ridge practices were increased maize grain yield and 1000 seed weight (g)by up to 45.52% (2.79 tonha-1) and 41.43% over farmer practice (control) respectively. And also furrow closed at both end increased the grain yield and thousand seed weight (g) by up 30.68% (1.88 tonha-1) and 27.63% as compared to farmers' practice respectively. Therefore, in situ moisture conservation (tied ridge and furrow closed at both end) structure is promising moisture conservation structures to mitigate dry spell period and improve maize production in the study area and similary agro ecology.
