Pollination is an essential process in the production of seed plants, it results in a genetically diverse production of offspring and its role is not well understood and appreciated in the local farming system. This study was conducted to evaluate the effect of honeybees pollination on Black cumin seed yield and yield related parameters at Sinana Agricultural Research center at on-station. The study had three experiment; these includes plots caged with honeybees (T1), plots caged without honeybees (T2) and open pollinated plots (T3). All collected data were analyzed using One-way-Analysis of Variance (ANOVA). In the study seven species of insects were identified as Nigella sativa visitors or pollinators with the most frequent visitors were honeybees at 11:30 am time and minimum at 3:00 pm on open pollinated plot. There were no significant different (P>0.05) on Date of blooming, Date of flowering, Flowering period, Primary and secondary branches among the three treatments. Whereas, there were a significant difference (P |
