Abstract

Conservation agriculture (CA) technologies involve minimum soil disturbance, permanent soil cover through crop residues or cover crops, and crop rotations for achieving higher productivity. Today tillage is seen destroying activity that leads to decline in organic matter and destruction of soil structure. Hence, the objective of this study was then to improve soil moisture and structure through minimizing soil disturbance which can be explained by the obtained yield response of sorghum. The research was undertaken at twenty one (21) interested farmers’ piece of land (10 m x 10 m) at Tanqua Abergelle Wereda in specific sites called Sheka Tekli and Agbe tabias’, it was successful only at thirteen (13) farmer’s land at Sheka Tekli. The conservation farming practices such as basin was prepared two weeks earlier from its sowing date. Grain yield and farmers perception on each practice of conservation agriculture were collected and subjected to simple descriptive statistics. Accordingly, the grain yields obtained from tied-ridger and basin technologies were 1.6 t/ha and 1.31 t/ha, respectively. However, conventional tillage revealed the lowest grain yield of sorghum. Farmers have shown great interest and promise to adopt tie ridger than basin due to lower yield. Therefore technology promotions and popularization on the study and similar agro ecological areas should be carried out in collaboration with stakeholders.
