Black seed, Planting dates, Seed yieldAbstract
The research was carried out during the Agronomic season 2018-2019 in Jarjanaz, located at eastern countryside of Maarat al-Numan, in the Idlib governorate.
The research aims to study the response of the black cumin to different planting dates and their impact on the productive Traits of this crop.
The seeds were planted in a dry way and on lines [20 x 500] cm (The length of the line is 5 m, and the distance between the line and the other is20 cm).
The experiment was carried out according to a randomize complete block (RCBD)with4 replication with 4 sowing dates. The dates of experiment are (December 1 st, December 20th, January 10 th, and the first of February) respectively The results showed that early planting in the first date led to a significant superiority in biological yield [3047] kg/ha, and to superiority in seed yield [2130] kg/ha, as well as the number of seeds/plants [723] seeds/plant and weight of seeds/plant [1.850]g.The relationship was positive, significant, and insignificant between yield, number and weight traits of seeds/plant, and biological yield, and not significant with the trait of 1000-seed weight.
