Leaves are capillary, pinnatisect, 2.5 to 5.0 cm long, cut into numerous fine linear, lanceolate, segments, not involucrating the flower. Effect of Nitrogen, Phosphorus & potassium on morphological characters of Nigella under Mandsaur region of Madhya Pradesh. Among the yield and yield attributes application of different levels of NPK showed the significant variations expect harvest index (%), oil content in seed (%). However, T₈ - 70:70:55 kg ha^-1 NPK was registered with highest value of number of capsules plant^-1 (77.13), number of seeds capsules^-1 (106.87), seed yield g plant^-1 (19.69), seed yield q ha^-1 (10.24), biological yield q/ha (43.09), test weight (3.17 g), harvest index (27.91%) and oil content in seed (0.46%) compared to T₁ - 40:20:20 kg ha^-1 NPK (recommended dose).
