Abstract:

Bread wheat is an important food security and cash crop in Ethiopia, particularly in the Bale and Arsi highlands. However, the yield of the crop is constrained by poor soil fertility management practices. Therefore, a field experiment was conducted during the 2015 main cropping season at Selka Kebele of Sinana District in Bale zone of Oromia Regional State, southeastern Ethiopian with the objective of investigating the influence of biochar, farmyard manure, and mineral nitrogen fertilizer on soil physico-chemical properties and yield, and yield components of bread wheat. The treatments consisted of two levels of farmyard manure (0 and 6 tons ha-1), three levels of biochar (0, 5, and 10 tons ha-1) and three levels of nitrogen (0, 23 and 46 kg N ha-1). The experiment was laid as a randomized complete block design (RCBD) with three replications using the improved bread wheat variety Sanete (14F/ HAR 1685) as a test crop. The results revealed that the interaction effects of biochar, farmyard manure, and mineral nitrogen fertilizer significantly (P
