The Effect of Nitrogen and NPS Fertilizer Rates and Inter-row Spacing on the Growth and Yield of Head Cabbage (Brassica oleracea L.) under Irrigation in Bako, Western Oromia, Ethiopia

Head cabbage is a popular leafy vegetable consumed all over the world. However, a number of factors, such as diminished soil fertility and poor agronomic practices, frequently restrict the crop’s production and productivity. A study was conducted at Bako Agricultural Research Center, under surface irrigation, during the cropping seasons of 2022 and 2023 for two years, to determine the effects of three levels of inter-row spacing, Nitrogen from urea, and Phosphorus from (NPS), were laid out in a randomized block design with three replications in a 3x3x3 factorial arrangement. The results analysis of variance indicated that the inter-row spacing of 55 cm had a substantial effect on the marketable yield (27483 kg ha-1) and total yield, (31842 kg ha-1). Likewise, 69 N ha-1 fertilizer rates from urea gave the highest marketable yield of 27861 kg ha-1 and total cabbage yield of 31824 kg ha-1. The partial budget analysis across year showed the highest net benefit of, 274720.0 birr obtained. Therefore, application 69 N ha-1 fertilizers and 100 kg ha-1 NPS with inter-row spacing of 55 cm under irrigation can be recommended for the production of head cabbage in study area and similar agroecology ecology based on the study’s findings
