Abstract:
Bread wheat is one of the key food crops in the study area and grown for home consumption,
market and strategic crop to address food security in Ethiopia. However, the productivity and
yield is mostly constrained by soil fertility and lack of better fertilizer rate in the study area.
The study was conducted at Bule Hora District, southern Ethiopia during the main cropping
season of 2023. The study was aimed to determine the combined application of NPS and
Urea(N) fertilizer rate for bread wheat (Triticum aestivum L.) production and to identify the
optimum fertilizer for higher grain yield with the higher economic return. The treatments
were: (0 NPS)negative control, 60Kg NPS, 120kg NPS, and 180 kg NPS) and (0N)negative
control, 140kgN, 280kg N) and positive control (100/100kg ha -1 NPS/ N). The treatments were
arranged in a randomized complete block design and replicated three times
