An on-farm study at Kesobpur, Titas, Cumilla (AEZ-19) during 2022–23 and 2023–24 evaluated an improved cropping pattern—Mustard (BARI Sarisha-18)–Sesame (BARI Til-4)–B. Aman rice (BRRI dhan91)—against the farmers’ existing Mustard (Tori-7)–Fallow–B. Aman rice (Furchun). The improved system, tested in an RCBD with five replications, significantly (P < 0.05) increased yields of all component crops. Mean rice equivalent yield (REY) was 15.32 ± 0.33 t ha⁻¹, 151% higher than the existing pattern. Production efficiency, land-use efficiency, harvest index, gross return (Tk. 329,757 ± 7,000 ha⁻¹), and gross margin (Tk. 209,860 ± 6,250 ha⁻¹) were also significantly higher. The marginal benefit–cost ratio (4.39) confirmed economic superiority. The Mustard–Sesame–B. Aman rice pattern is statistically and agronomically superior and recommended for wider adoption in AEZ-19 and similar agro-ecological zones of Bangladesh.
