The prevalence of challenges on mineral fertilizer such as escalating cost in Ethiopia urged to explore and exploit alternative organic nutrient sources like cow urine. Hence, the current study was initiated to understand the composition dynamics across bred types and storage conditions of Cow urine, and evaluate its effect on wheat growth, yield, and quality and soil properties. The composition dynamics phase was dealt in laboratory and had 30 factorial combined treatments of bred type (local and cross breed), temperature (4, 21 and 38°C) and time (0, 24, 48, 72 and 120 hours) laid in triplicate and completely randomized design. The crop response evaluations had treatments of factorial combined urea: Cow urine integration and urine concentration with respective levels of (0:0, 100:0, 0:100, 50:50 and 75:25) and (15, 25, 35, 50, 75and 100%) for the pot, and (0:0, 100:0, 25:75, 50:50 and 75:25) and (0, 15 and 50%) for the field. The result showed that storage time and breed type highly influenced the total nitrogen and total phosphorus composition of Cow urine as compared to 0hr. Total phosphorus at 120 hour and total nitrogen at 48 hour were the highest records. Likewise, local bred total nitrogen and total phosphorus were superior to cross breeds with records of 0.9%, and 22%, respectively. Supplementation of 75% Recommended nitrogen from urea with 25% Recommended from Cow urine and 50% Recommended nitrogen from urea with 50% Nitrogen from Cow urine exhibited the highest biomass and grain yield of wheat irrespective of the farm typology and statistically at par with the full Recommended from urea (positive control). Further validation of the output is essential to confirm the effectiveness of the technology.
