EFFECT OF PLANTING DATE AND FOLIAR APPLICATION OF HUMIC ACID ON VEGETATIVE GROWTH, YIELD, AND FIXED OIL OF BLACK CUMIN PLANTS
An experiment was established to study the influence of humic acid (HA) application at different rates (0, 1.5, 3.0 and 4.5 g/l) on vegetative characters and the production of black cumin (Nigella sativa L.) sown on three different dates (15th Oct., 1st and 15th Nov.). The plants cultivated on the f...

| description | An experiment was established to study the influence of humic acid (HA) application at different rates (0, 1.5, 3.0 and 4.5 g/l) on vegetative characters and the production of black cumin (Nigella sativa L.) sown on three different dates (15th Oct., 1st and 15th Nov.). The plants cultivated on the first date (15th October) gave the best results compared to the late dates concerning plant height (61.54 and 55.34 cm), branch number/plant (4.42 and 3.62), stem diameter (5.71 and 4.42 mm), number of capsules/plant (18.10 and 16.75), seed yield/plant (8.70 and 8.92 g), total seed yield/feddan (464.03 and 475.38 kg), fixed oil percentage (19.88 and 17.28 %), fixed oil/plant (1.76 and 1.59 ml), fixed oil/feddan (93.88 and 84.52 l), chlorophyll a (0.57 and 0.57 mg/g), chlorophyll b (0.30 and 0.75 mg/g) and carotenoids (0.32 and 0.43 mg/g) during both seasons respectively. Foliar application of HA in medium rate (3 g/l) gave the best productivity of the same previous parameters compared to the lower and higher rates: plant height (58.46 and 53.33 cm), branch number/plant (3.90 and 3.65), stem diameter (5.57 and 5.00 mm), number of capsules/plant (14.94 and 14.67), seed yield/plant (8.26 and 9.13 g), total seed yield/feddan (440.62 and 486.70 kg), fixed oil percentage (26.63 and 23.30%), fixed oil/plant (2.20 and 2.11 ml) and fixed oil/feddan (117.26 and 112.67 l) during both seasons respectively. The application of humic acid in the medium concentration on black cumin sown in mid-October seems to be the best interaction for getting higher seed yield and a high percentage of fixed oil. |
