The study was executed in the experimental field of Irrigation and Water Management Division (IWM), Bangladesh Agricultural Research Institute (BARI), Bangladesh to investigate the effect of irrigation on onion seed yield. There were six irrigation treatments: T1= Irrigations at vegetative, bolting, flowering and seed formation stages, i.e., no stress, T2= Stress at vegetative stage, T3= Stress at bolting stage, T4= Stress at flowering stage, T5= Stress at seed formation stage, and T6= Irrigations at vegetative and flowering stages (Farmers practice). Bulb to seed method was used for this study. Recommended doses of fertilizers for “BARI piaz-1” were applied for all treatments. Measured amount of irrigation water was applied at different growth stages according to the treatment combinations. Data on yield attributing characters, yield, and seasonal water use were recorded. Results showed that umbel diameter and 1000- seed weights were significantly influenced by different irrigation treatments. Irrigation treatments did not show any significant effect on other yield contributing characters studied. The highest yield (1110.89 kg/ha) was observed from the treatment receiving irrigations at four different growth stages while the treatment in which stress was imposed at flowering stage produced the lowest seed yield (897.70 kg/ha). Water productivity was observed highest (0.45 kg/m3) in treatment T5 while the lowest (0.38 kg/m3) was observed in treatment T4. The highest benefit-cost ratio (3.84) was obtained from treatment T1 while the lowest one (3.14) was found in treatment T4. The results suggested that irrigation at the flowering stage is critical for onion seed production.
