Ethiopia was using urea and DAP fertilizers as sources of nitrogen and phosphorous
nutrients for a long time. However, the crop and agro-ecology diversity in the country demand more multi-nutrient blends including micronutrients than nitrogen and phosphorus. This increasing demand requires evaluation of different fertilizer resources based on soil type, crop species, and location to provide new alternative fertilizer products to Ethiopian production system. Cognizant of this fact, an experiment was conducted to evaluate the efficacy of Tradecorp AZ Bentley plus as a supplementary fertilizer to improve yield of tomato under irrigation in different areas in east Shoa Zone of Oromia, during 2018-2019. The experiment consisted of five treatments ( Control, recommended fertilizer, recommended fertilizer + 1.8 kg product, recommended fertilizer + 3.0 kg product and recommended fertilizer + 4.2 kg product) laid out in randomized complete block design (RCBD) with four replications. The results revealed that application of Tradecorp AZ Bentley plus fertilizer product improved tomato marketable and total yields at testing sites. In addition, the application of Tradecorp AZ Bentley plus as supplementary fertilizer in combination with the recommended fertilizer rate attained acceptable net returns of tomato at both locations. Hence, Tradecorp AZ Bentley plus is recommended as supplemental fertilizer for tomato producing farmers in testing areas.
