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.

Yield And Yield Components

A field experiment was carried out to study the influence of sowing times on yield and yield components of barley (Hordeum vulgare L.). Seeds of four barley cultivars (BB 1, Karan 19, Karan 163 and Karan 351) were sown with four sowing times (5 November, 17 November, 29 November and 11 December). Most of the yield and yield components were significantly highest in 17 November sowing. Among the cultivars most of the characters showed their highest values in BB 1 and the lowest in Karan 19. Harvest index was found highest in Karan 351 and lowest in BB 1. Key words: Barley, Sowing time, Yield.   doi: 10.3329/jbs.v15i0.2154   J. bio-sci. 15: 139-145, 2007

Canola, Indian mustard, and wheat were grown under dryland conditions at Ariah Park and Cowra (canola only) in the cropping belt of New South Wales, Australia, to determine the effects of sowing time (canola and wheat) and nitrogen (N) fertiliser on the growth, grain yield, and yield components of the crops. Compared with an April sowing, the grain yield of canola at Ariah Park was reduced by 35% for a May sowing and by 67% for a July sowing. Canola yield at Cowra was reduced by 45% between early and late May sowings. Wheat yield declined by 35% between the May and July sowings at Ariah Park. Grain yields of canola and wheat at Ariah Park responded to N fertiliser in the April and May sowings, but not in the July sowing. Indian mustard had a higher yield than thecomparable sowing of canola. Canola yields at Cowra were more responsive to N fertiliser than at Ariah Park, and increased from 0.5 to 2.9 t/ha with 100 kg N/ha. For each day that sowing canola was delayed at both sites after Aprill—early May, anthesis was delayed on average by 0.52 days. For Dollarbird wheat, the delay in anthesis was 0.39 days per day sowing was delayed. Dry matter accumulation by the oilseeds was greatest during flowering, but before anthesis for wheat. Late sowing had little effect on the proportions of dry matter accumulated in a particular growth period. Irrespective of sowing time, grain yields and dry-matter harvest indices of the oilseeds were similar to values for wheat when differences in the biosynthetic costs of grain and straw production were taken into account. Late sowing usually resulted in a greater reduction in canola oil concentration than high N fertiliser rates. Canola oil concentration was reduced by 1.7 percentage points per 1mp;deg;C increase in mean temperature during grain filling as a result of sowing late. It was concluded that N fertiliser could not compensate for the yield reduction in canola and wheat due to sowing late. Early sowing was essential to achieve high oil levels in canola.
