Growth and yield attributes of black cumin (Nigellla sativa L.) as affected by sowing dates and methods

A field trial was carried out at the Research fields of Agronomic Research Institute Faisalabad, Pakistan (2010-11) to estimate the influence of different sowing dates and types of methods on growth and yield attributes of black cumin (Nigellla sativa L.). Four no. of planting dates with the interval of 15 starting from 15th October to 30th November 2010 were selected accordingly. Four types of sowing methods like broad casting, line, ridge and bed sowing were appraised. The experiment was laid out as a split plot arrangement of a randomized complete block design with three repeats. Black cumin sown on 15th October produced the highest plant growth and seed yield with higher capsules plant^-1, seeds capsules^-1 and 1000-seed weight than other treatments. The yield was significantly decreased with each late interval in sowing from 15th October to 30th November. Bed sowing produced the highest seed yield followed by ridge sowing, line sowing. The lowest seed yield was recorded in broad cast method of sowing.
