Abstract :An experiment was conducted to evaluate the effect of sowing date and plant density on yield and yield components of Black Cumin Cuminum carvi L. under dry farming conditions. Four plant densities 50, 100, 150 and 200 plants m-2 and three sowing dates 3, 13 and 23 of March were applied. Result showed that seed yield was influenced by sowing date and plant density interaction. Early sowing date resulted in higher seed yields as evident from higher aboveground biomass, the number of umbrella per plant, the number of seed per umbrella and plant height. Harvest index and 1000-seed weight were not affected by sowing date and planting density. Earlier sown plants with density of 200 m-2 resulted in higher seed yields
