“…Therefore, height and the number of leaves per plant were significantly affected by AGDD. Results of the previous studies were in line with the findings of the present study (Pandey and Paul 2017; Gloaguen et al 2018). Meena and Rao (2013) suggested that AGDD is more important for plant growth than the number of days after seed sowing.…”

The present experiment was conducted to determine the impact of accumulated thermal time on the growth, yield and phenology of Sesame (Sesamum indicum L.) in the dry zone of Sri Lanka. Uma, Malee and MI-3 varieties were selected and the seeds were sown on three different dates in the 2016 Yala and 2016/2017 Maha seasons. The experiment was set up according to a two-factor factorial randomized completely block design with three replicates. Accumulated thermal time was calculated as growing degree days at the vegetative stage, flowering initiation, 50% of flowering, 100% of flowering and physiological maturity using minimum and maximum daily temperature. Then the plant height and the number of leaves per plant were plotted against the accumulated thermal time using the sigmoid growth model. The seed dry weight and dry weight of 1000 seeds were recorded at maturity. The relationship of plant height and the number of leaves per plant with accumulated growing degree days (AGDD) was significant for all varieties at different sowing dates in both seasons. The flowering of sesame initiated at 741 and 713.1 of AGDD in Yala and Maha seasons, respectively. The AGDD needed for 50 % flowering in the Yala is greater than the Maha season. Full flowering occurred in Maha earlier than the Yala season. Plants reached physiological maturity early in the Maha season. Seed weight per 15 plants and seed weight per plot were significantly affected by the interaction between variety and the sowing date in Maha and Yala seasons, respectively. The highest seed weight per 15 plants was recorded in var. Uma and var. Malee in Yala season while the highest seed weight per plot was also recorded by var. Uma. Furthermore, 1000 seed weight was greater in var. Uma than other varieties in both seasons. Sowing seeds early in the season increased seed weight per 15 plants in Yala while seeds per plot and 1000 seed weight in Maha season. According to the results of the present study, var. Uma could be considered as an efficient sesame variety that performed better when sown early in the season. Therefore, cultivating var. Uma, early in the seasons might be beneficial in terms of growth and yield in the dry zone of Sri Lanka. However, further field studies are needed to give a solid recommendation.

“…Achieving higher leaf water content in the first planting date resulted in less water loss (0.159). These results align with studies conducted on sesame varieties with different planting dates, where early planting dates generally excelled in most studied plant traits [9,14,15].…”

“…The earliest planting date on March 15 excelled in plant height, height to first capsule, and number of branches per plant. Another study conducted in Florida, Southeastern United States, by Gloaguen et al, [9] when sesame was planted on three dates (May, June, and July), showed significant differences among traits. The earliest planting date (May) excelled in plant height, number of branches on the main stem, and productivity per unit area, achieving the highest averages for those traits.…”

A Field experiment was conducted during the summer season of 2023 at the Al-Hamadiyah station, College of Agriculture, University of Anbar, east of Ramadi city, Iraq, with the aim was to determining the effect of planting dates on four varieties of sesame crop. A randomized complete block design (R.C.B.D) was used with three replications, in a split-plot arrangement, where planting dates (1/5, 15/5, and 1/6) occupied the main plots and varieties (Had, Al-Rafidain, Common Local, and Foreign) occupied the subplots. The results showed a significant increase for the first planting date in all the studied traits, namely: number of branches, leaf area, leaf water content, lesser water loss, higher chlorophyll content in leaves, and plant dry weight (all traits were measured at the beginning of flowering) (5.72 branches plant-1, 463.10 dm2, 99.77, 0.159, 55.82 SPAD, and 96.42 grams, respectively,). While, the second planting date achieved lower averages for the aforementioned traits, except for water loss, which recorded a lower average of 0.122%. The Hade variety excelled in the number of branches (6.46 branches plant-1), leaf area (463.10 dm2), and dry weight (86.56 grams plant-1). In contrast, the foreign variety had the highest relative water content and the least water loss percentage (93.77 and 0.123) respectively. The Rafidain variety showed the lowest number of branches, at 3.82 branches plant-1. The interaction between the two factors had a significant effect on all studied traits, indicating a difference in the response of plant varieties to the effect of planting dates.

“…Besides, Çağirgan et al [ 66 ] stated that screening for closed capsules is advisable to arrange M2 populations in the form of M1 plant progenies instead of bulk, although the cc-1 is selected in a bulk. Furthermore, other studies developed non-dehiscent sesame varieties that succeeded in producing and releasing dozens of high shattering resistance varieties [ 67 , 68 ]. Moreover, Couch et al [ 62 ] developed improved non-dehiscent sesame variety (named S29) with shattering resistance.…”
