Abstract: Black cumin is an important spice cum medicinal crop mostly grown in northern parts of India and is being grown on small scale in south India, more specifically in certain areas of Karnataka as a rabi season crop owing to its high medicinal value. Considering the importance, demand and price offered for this spice cum medicinal crop across the country, farmers in the non-traditional areas like Karnataka are fascinated for the cultivation of black cumin. For profitable cultivation of this crop under Bengaluru conditions, efforts are needed to understand cultivation practices on scientific lines to realize maximum returns per unit area and time. In the recent years, the use of elicitors was found to be one of the best possible ways to achieve spectacular progress in increasing production, productivity and quality of seed spices. Hence, the study was taken up with foliar application of different elicitors and manual pinching in black cumin during Rabi seasons of 2018-19 and 2019-20 with an objective to study the cost-economics of elicitors in black cumin cultivation. The results of the investigation inferred that, the maximum gross returns (Rs 3,49,500 ha^-1) and net returns (Rs. 3,05,974 ha^-1) was from black cumin plants applied with salicylic acid at 50 ppm resulting in highest B:C ratio of 8.02. While, the treatment involving the application of ancymidol at 50 ppm had inferior effect and resulted in least net returns of Rs 1,21,248 ha^-1 with a B:C ratio of 2.64, owing to its high cost of cultivation due to high price of chemical.
