Field experiments were conducted during 2018/2019 at two locations; Toke-Kutaye and Ilu-Gelan districts in west Shoa zone, Ethiopia, to evaluate Bombardier fertilization on growth and yield of tomato. The experiments were laid out in randomized complete block design with three replications. The treatments consisted of control, conventionally recommended di-ammonium phosphate (DAP) 196 kg ha-1 plus 97 kg ha-1 urea, Bombardier fertilizer (10Lha-1), DAP (196 kg ha-1) plus urea (97 kg ha-1) plus Bombardier fertilizer (10Lha-1). The highest plant height (70.78 & 65.44 cm), number of primary branches (4.78 & 4.44) and secondary branches (10.89 & 7.44) at Toke-Kutaye and Ilu-Gelan respectively recorded in the plot received combination of Bombardier and conventional fertilizer While the lowest results were obtained in untreated plot. The highest number of fruits per plant (67.89 and 65.89), marketable yield (51.8 & 43.53 tonnesha-1) and highest total yield (55.53 & 48.53 tonnesha-1) at Toke-Kutaye and Ilu-Gelan, respectively were from applying Bombardier and conventional fertilizer together and the lowest values were recorded from control treatment. Bombardier also influenced total soluble solids, pH and titratable acidity. The positive effects of combining Bombardier with DAP and urea treatments suggest that, Bombardier is promising in improving fruit yields of tomato.
