“…This may be attributed to the competition between the different plant parts under high planting density. Similar findings were reported by Mujaya and Yerokum (2003), Adebisi et al (2005) and Abdalla et al (2008). However, the number of capsules per plant increased with increasing nitrogen levels in both seasons (Table 2).…”

“…Therefore, under these circumstances, _______________________________________________________________________ maintaining an optimum plant density plays a vital role in realizing the yield potential of the crop (Guanamurthy et al 1992;Ghosh and Patra, 1994;Caliskan et al 2004). Generally, a favourable increase in yield is obtained with increase in plant population, and a stand of up to 222 000 plants/ha is considered necessary to obtain reasonably good seed yield (Subrahmaniyan and Arulmozhi 1998;Adebisi et al 2005). With further increase in density beyond 330 000 plants/ha, the number of capsules per plant and seed weight per capsule decreased significantly (Mujaya and Yerokum 2003).…”

The interactive effect of plant density and nitrogen fertilizerlevels on growth and yield of sesame (Sesamum indicum L. cv. Shuak)was investigated under irrigation. The field experiments were conductedduring 2005/06 and 2006/07 seasons in the Experimental Farm of theFaculty of Agriculture at Darmali, Nile Valley University, River NileState, Sudan. Four plant densities (100 000, 150 000, 200 000 and 250000 plants/ha) and three levels of nitrogen fertilizer (0, 22 and 44 kgN/ha) were used. A split-plot design with four replications was used toexecute the experiment. The plants were sown during the first week ofJuly. The results showed that plant height, number of branches per plant,height to first capsule and leaf area index were significantly affected byplant density and level of nitrogen fertilizer. The highest values of thesecharacters were obtained with a plant density of 250 000 plants/ha andtreatment receiving 44 kg N/ha. Increasing plant density significantlydecreased the number of capsules per plant, seed yield per plant andincreased seed yield per unit area. Nitrogen levels significantly increasedseed yield and number of capsules per plant. Significant interaction wasnoted, and the highest seed yield was obtained by the application of 44 kgN/ha at a planting density of 150 000 plants/ha

“…However, the other eight genotypes had a value of Ys i less than the mean Ys i .Therefore; these genotypes were judged to be unstable. These results are agreement with Gebeyahu and Assefa (2003) and Adebisi et al (2010).…”

The present study aimed to estimate different stability statistics to evaluate the behavior of some sesame genotypes grown under12 diverse environments in four successive summer seasons of 2011, 2012, 2013 and 2014. Forteen sesame genotypes, in addition to one check cultivar, were planted in three locations of upper Egypt, [Shandaweel (Sohag), El-Mataana (Luxor) and Mallawi (Elmenia)]. The design used was randomized complete blocks design with three replications as well as using four stability methods [Eberhart and Russell (1966), Tai 1971, shukla (1972 and Kang and Magari (1995)]. The studied characters were plant height, length of fruiting zone, number of capsules/ plant,1000 seed weight, seed weight/plant (g) and seed yield (ardeb/fed). Results indicated that the genotypes significantly differed for all the studied traits. Also genotype x environment (GxE) interaction was highly significant for all the studied traits. Genotype No.12 (N.A.653) was phenotypically and genotypically stable using the three stability procedures of Eberhart and Russell (1966), Tai (1971), and Kang and Magari (1995) for plant height. Considering fruiting zone length, genotype No. 4 (B21) was stable using the three stability methods while the genotype No. 6 (N.A. 463) was stable for number of capsules/ plant using the same three methods of stability. Concerning 1000 seed weight, genotype No. 6 (N.A. 463) was stable by using Shukla (1972) and Kang and Magari (1995) methods of stability. The results revealed that genotype No. 5 (Hybrid167), No. 10 (N.A.542) and No.12 (N.A.653) for seed weight/plant, and genotypesNo.4 (B21), No.5 (Hybrid167) and No.10 (N.A.542) for seed yield (ardab/fed), were stable by using two methods of stability Eberhart andRussell, 1966 andMagari, 1995 . In light of the current results, it can be concluded that genotype No. 5 (Hybrid167) may be recommended to be released as a commercial stable genotype for seed weight/plant (g) and seed yield (ardab/fed) by using two methods of stability (Eberhart and Russell (1966) and Kang and Magari (1995), and incorporated to be as a breeding stock in any future breeding program.

“…Sesame seed oil also has valuable applications in industries. It is used in the manufacture of cosmetic products (Barel et al, 2014;Weldemichael and Juhar, 2018), soaps (Warra et al, 2016;Sharma et al, 2017;Hassan and Wawata, 2019), biodiesels (Mujtaba et al, 2020;Nematian et al, 2021;Lee et al, 2022), biopesticides (Vasanthi and Rajavel, 2021), and varnishes (Adebisi and Ajala, 2011). Additionally, sesame seeds have a very rich flavor profile with over 200 volatile compounds that can be used as food additives (Jia et al, 2019;Yin et al, 2019).…”

Sesame (Sesamum indicum L.) is one of the most recommended oil crops due to its nutritional and medicinal properties. It is a tropical and subtropical plant; however, it is also cultivated in arid and semi-arid regions, including Morocco. Nevertheless, the sesame crop in this country faces many constraints and challenges that restrict its production potential. The objective of this study is to present the situation of sesame production in Morocco during the last twenty years by describing and discussing the seed production, the harvested area, the value of imports, and the most important challenges. Also, some relevant strategies and measures to counteract these constraints and, thus, improve sesame production have been proposed and discussed. To make a fair diagnosis, a survey was carried out among 33 sesame producers in the Tadla area, in addition to the national and international databases that were consulted. The results showed that sesame area and production dropped markedly between 2000 and 2020. As a result, the import quantities and values have been significantly and gradually increased during the same period. The observed decline in both the area and the production may be due to several constraints including recurrent drought, restricted supply in irrigation water, poor cultural practices, low-yielding cultivars, and pests and diseases. Therefore, there is an urgent need for scientific research in terms of breeding to develop and release high-performing and adapted varieties and crop management to find and adopt the best cultural practices. Besides, sesame producers should organize themselves in associations or cooperatives to ensure an added value of their production and improve their profit margin and income. All these actions and measures would be able to promote and develop the sesame sector in Morocco to meet and satisfy the high domestic and global demand for this precious and valuable seed.
