Nigella sativa L. is an annual herbaceous seed spice crop belonging to the family Ranunculaceae. It is widely cultivated throughout South Europe, Syria, Egypt, Saudi Arabia, Iran, Pakistan, India and Turkey. The nigella seeds are also known as black cumin. It has been used as herbal medicine for more than 2000 years. As seed spice, it is also used as food additive and flavour in many countries. Considering its economic and medicinal importance a field experiment was conducted during rabi crop season of 2012-13 and 2013-14 at ICAR - NRCSS research farm, Ajmer (Rajasthan), India to evaluate suitable and economical methods of weed management & its effect on yield attributes of nigella. The experiment was laid in randomized block design with 10 treatments including control and three replications each. Results of the two year data revealed that after weed free treatments (T1) the highest yield attributes like maximum number of siliqua plant-1 (17.67), number of seeds siliqua-1 (83.83) and test weight (1.88 g) as well as seed yield (8.81 q ha-1) and straw yield (23.10 q ha-1) were recorded with the pre- emergence application of oxadiargyl @ 75 g + one hand weeding at 45 DAS (T2), followed by post emergence (Pt.E) application of oxadiargyl @ 75 g at 20 DAS + one hand weeding at 50 DAS (T4). The lowest values of yield attributes and yields were recorded in weedy check (T4). The highest gross returns and net returns per ha was obtained in weed free treatment (T1) followed by effective weed
control with oxadiargyl (T2) after sowing, the highest B: C ratio (2.62) was recorded with pre-emergence application of oxadiargyl (T2).
