Determination of Yield and Yield Components in Different Sowing Times of Black Seed (Nigella sativa L.) in Hatay Ecological Conditions

This study was carried out in order to determine the yield and yield components of Nigella sativa L. grown in different cultivation periods in Hatay ecological conditions at Mustafa Kemal University, Faculty of Agriculture, Medical Plants trial area in 2018-2019. The experiment was laid out at spilt plot in randomized blocks with three replications. Trial; The parcels split in random blocks were carried out with 3 repetitions according to the trial pattern. In the trial, sowing was carried out on 15 November, 1 January, 15 February, 1 March, 15 March, 1 April, 15 April, 1 May and 15 May. In the study, some properties related to phenological, herbal properties, yield and yield components were examined during field trial and after harvest. As a result of the measurements taken, the plant height is 19.03-54.00 cm, the number of branches is 8.80-3.78 number/plant the number of plant capsules 3.73-20.67 number/plant, thousand grain weight is 3.04-2.10 g, seed yield is 3.65-51.81 kg.da-1, constant oil rate % was found between 22.47-32.07 values. Due to the increase of summer temperatures early in Hatay ecological conditions, the yield and yield factors of summer planting decreased in this period compared to winter planting. For this reason, November 1-15 is recommended as the most suitable sowing time for black seed in Hatay ecological conditions.
