“…The reason could be attributed to the difference in the genetic characteristics of the cultivars and their speed of response to environmental conditions, which was reflected in the variation in the number of branches per plant. The results are in line with findings of previous studies [15,16] which pointed out that the number of branches is depended on genetic diversity among sesame cultivars.…”

A field experiment was conducted in the summer season of 2023 at the Hamidhia Research Station of the College of Agriculture - University of Anbar at latitude and longitude (33.45, 43.38). With aim to study the growth traits of four sesame cultivars under the influence of potassium fertilizer spraying. The experiment was implemented using a randomized complete block design (RCBD) with split-plot arrangement and three replications. The potassium concentrations (0, 2000, 4000, 6000) mg L-1applied as foliar s applications, allocated to the main plots while the cultivars (Wada’a, Black Malaysian, Magnali 53, Golmarmuros) occupied the sub-plot. The results demonstrated that the Magnali 53 cultivar excelled in plant height (157.87 cm), branch number (6.98 branches per plant), chlorophyll index (55.51 SPAD), leaf area (6853 cm2 per plant), and leaf area index (5.47). On the other hand, the Wada’a cultivar showed superiority in days to flowering with 37.33 days. The concentration of 4000 mg L-1 yielded the highest averages plant height (166.50 cm), branch number (6.08 branches plant-1), chlorophyll index (55.79 SPAD), leaf area (7091 cm2 plant-1), and leaf area index (5.66). The results indicated the significance of the interaction between potassium application concentrations and cultivars in plant height, chlorophyll content, leaf area, and its index.

“…Also, it has been demonstrated that plant density in the farm is one of the most important factors that influences sesame yield [63]. A study by Ali et al [64] in Gedaref showed that planting sesame at 5 cm between rows can increase its yield by 210.18 kg ha −1 . For sorghum, our results showed that the climatic variables were responsible for 70% of the variation in its yield.…”

Climate Variability and Change Affect Crops Yield under Rainfed Conditions: A Case Study in Gedaref State, Sudan

It is projected that, on average, annual temperature will increase between 2 °C to 6 °C under high emission scenarios by the end of the 21st century, with serious consequences in food and nutrition security, especially within semi-arid regions of sub-Saharan Africa. This study aimed to investigate the impact of historical long-term climate (temperature and rainfall) variables on the yield of five major crops viz., sorghum, sesame, cotton, sunflower, and millet in Gedaref state, Sudan over the last 35 years. Mann–Kendall trend analysis was used to determine the existing positive or negative trends in temperature and rainfall, while simple linear regression was used to assess trends in crop yield over time. The first difference approach was used to remove the effect of non-climatic factors on crop yield. On the other hand, the standardized anomaly index was calculated to assess the variability in both rainfall and temperature over the study period (i.e., 35 years). Correlation and multiple linear regression (MLR) analyses were employed to determine the relationships between climatic variables and crops yield. Similarly, a simple linear regression was used to determine the relationship between the length of the rainy season and crop yield. The results showed that the annual maximum temperature (Tmax) increased by 0.03 °C per year between the years 1984 and 2018, while the minimum temperature (Tmin) increased by 0.05 °C per year, leading to a narrow range in diurnal temperature (DTR). In contrast, annual rainfall fluctuated with no evidence of a significant (p > 0.05) increasing or decreasing trend. The yields for all selected crops were negatively correlated with Tmin, Tmax (r ranged between −0.09 and −0.76), and DTR (r ranged between −0.10 and −0.70). However, the annual rainfall had a strong positive correlation with yield of sorghum (r = 0.64), sesame (r = 0.58), and sunflower (r = 0.75). Furthermore, the results showed that a longer rainy season had significant (p < 0.05) direct relationships with the yield of most crops, while Tmax, Tmin, DTR, and amount of rainfall explained more than 50% of the variability in the yield of sorghum (R2 = 0.70), sunflower (R2 = 0.61), and millet (R2 = 0.54). Our results call for increased awareness among different stakeholders and policymakers on the impact of climate change on crop yield, and the need to upscale adaptation measures to mitigate the negative impacts of climate variability and change.

“…Our findings suggest that there is prospect of using those phenotypic characters as selection criteria in breeding programs for enhanced sesame yield. Ali et al (2020) also reported that taller plants with the higher number of capsules are favorable for seed yield improvement in sesame. In our study, genotypes BARI til-4, GM-11, CW-1, GM-10, GM-9 and GM-8 had the tallest plants accompanied with higher capsules plant -1 .…”

Identification of genetic diversity and their relationships among breeding materials is crucial in crop improvement strategies. In this study, 38 sesame genotypes were characterized for their genetic diversity. The results revealed significant variations among various traits such as plant height, maturity, capsule plant-1 and seeds capsule-1. The number of capsule plant-1 showed significant positive correlation with seeds capsule-1. The highest heritability was found for the numbers of capsules plant-1 (98.67%). The 38 genotypes were separated into six distinct clusters. Comparison within the populations of the cluster IV and those of cluster VI had the highest capsules plant-1, seeds capsule-1 with enormous genetic diversity. For molecular characterization, 7 microsatellite markers and 5 SSR primers with polymorphism were finally chosen for genetic diversity analysis. Altogether, 19 alleles were identified among the 38 genotypes, and the average number of alleles per locus was 3.80. The lowest and the highest numbers of alleles were 3 and 5, respectively. The polymorphism information content (PIC) ranged from 0.3201 to 0.5934 and SI-ssr30 showed to be highest at 0.5934. The UPGMA based clustering depicted a significant variation at molecular level among the sesame genotypes, having a coefficient of similarity between 0.29 and 1.00. The present study confirmed that extensive genetic diversity existed among the sesame genotypes and valuable agronomic traits may result in the development of high yielding genotypes.
