Wheat (Triticum aestivum L.) is a major cereal crop belonging to the family Poaceae, ranking second after rice in global consumption. A field experiment was conducted at the Agronomy Field Laboratory, Department of Agronomy and Agricultural Extension, University of Rajshahi, Bangladesh, from December 2019 to March 2020, to evaluate the effect of split urea application on the growth, yield-contributing characters, and yield of wheat. The experiment comprised two varieties—BARI Gom-26 (V₁) and BARI Gom-28 (V₂)—and four urea application schedules: T₁ (full dose as basal), T₂ (two equal splits at basal and 20 DAS), T₃ (three equal splits at basal, 20, and 40 DAS), and T₄ (four equal splits at basal, 20, 40, and 60 DAS). The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. Results indicated that split application of urea had a significant effect on all growth and yield parameters. The highest performance was recorded under T₄ treatment, which produced the maximum number of effective tillers per plant (6.28), spike length (10.56 cm), number of spikelets per spike (20.61), number of grains per spike (51), 1000-grain weight (46.01 g), grain yield (2.59 t ha⁻¹), straw yield (3.32 t ha⁻¹), biological yield (5.91 t ha⁻¹), and harvest index (43.78%). The interaction between V₂ (BARI Gom-28) and T₄ exhibited superior results in all yield parameters, achieving a grain yield of 2.64 t ha⁻¹ and biological yield of 6.01 t ha⁻¹. It may be concluded that BARI Gom-28, when fertilized with urea in four equal splits (basal + 20 DAS + 40 DAS + 60 DAS), enhances growth and yield performance of wheat under the agro-climatic conditions of Rajshahi, Bangladesh.
