Demonstration of Soil Test Based NPS Fertilizer Rate Based on Calibrated for Teff in Girar Jarso District of North Shewa Zone, Oromia

Abstract

The pre-extension demonstration of soil test based NPS fertilizer rate based on calibrated for Teff technology with its full packages practices was done to demonstrate and evaluate the newly adapted teff variety and thereby create awareness for farmers and agricultural extension agents. One improved teff variety (Dagim) was demonstrated Girar Jarso district in two kebeles (Wartu and Dire doyu) two peasant associations were selected purposely from the district based on teff production potential. The experiment was demonstrated on a simple plot with a size of 10 x 10 m. teff grain yield data, and farmer perceptions and preferences were collected and analyzed by simple descriptive statistics. The varieties showed remarkable variation in their yield potential across the testing areas. The average yield performance of the Dagim with soil test based (13.81 qt/ha) obtained from the farmer's field was relatively higher than Dagim without soil test based (10.12 qt/ha) variety and used local variety as a standard check. Similarly, the average yield performance recorded for Dagim with soil test-based technology was higher as compared to Dagim without soil test-based technology. Based on the procedure of variety evaluation and selection criteria, farmers set their criteria to evaluate and select the best variety following the real situation existing. Thus, against each of the criteria and weight attached, Dagim with soil test-based technology was selected for high yield, tolerance to disease and lodging, and early mature as compared to local variety. Therefore; it is important to scale up this variety/technology on a larger scale to improve yield. Thus, Dagim with soil test based NPS fertilizer rate based on calibrated technology Dagim with soil test based NPS fertilizer rate based on calibrated technology recommended for further scale-up.
