“…However, Patil et al (1992) reported that increased number of capsule plant -1 with delaying sowing might be due to difference in genetic makeup and climatic conditions. This finding was in agreement with the result obtained by Nath et al (2000) and Rai et al (1999).…”

To study the effect of dates of sowing and improved cultivars on growth and yield of summer sesame in North Bengal five different dates of sowing (10 th February, 20 th February, 2 nd March, 12 th March and 22 nd March and three cultivars of sesame (Rama, Savitri and Tillotama) with three replications. The highest (114.66 and 115.83 cm) plant height was recorded when sesame sown on 12 th March (D 4) and which was statistically at par with 2 nd March (D 3). Among the varying date of sowing, the highest dry matter accumulation, leaf area index and crop growth rate was recorded in 2 nd day of March compared to the other date of sowing. Among the improved cultivars of sesame, the variety Rama recorded higher plant height, dry matter accumulation, leaf area index and crop growth rate compared to Savitri and Tillotoma. The highest yield was recorded when sesame sown on 2 nd March which was 55.99 and 40.85% higher than the crops sown on 22 nd March during 2013 and 2014 respectively. Rama also exhibited highest seed yield recording 17.70 and 12.06% higher than the cultivars Tillotama and Savitri. The date of sowing significantly influenced the yield attributes and highest yield attributes was recorded when sesame sown on 2 nd March. Improved cultivar, Rama recorded the highest yield attributing characters compared to the Savitri and Tillotoma. It can be concluded that sowing of sesame within 2 nd March to 12 th March is the optimum sowing dates of sesame to have optimum seed yield if grown as late summer crop. Result indicated that cultivar Rama can be adopted in terai zone of West Bengal during summer season, because of its highest seed yield ability.

“…Sesame sown on 15 March produced the highest seed yield (760.1 kg ha -1 ), which was 3.4, 3.8 and 18.3% greater over 1 March, 1 April and 15 February, respectively. The finding contradicted Nath et al, (1997) [6] , where maximum seed yield of sesame varieties was obtained with sowing on 19 February compared to early (10 February) and delayed sowings (1 March to 28 April) at Kalyani, Nadia, West Bengal. Among three varieties, Rama recorded the highest seed yield (731.8 kg ha -1 ) due to significant improvement in yield components, stover yield (2390.0 kg ha -1 ) and oil content (38.4%).…”

In the context of optimizing sowing dates and varieties for realizing higher productivity notably for sesame an experiment with varying sowing dates and varieties was executed under the climatic scenario of New Alluvial Zone of West Bengal. The experimental findings reveal that crop sown on 15th March (2017) recorded highest seed yield (760.1 kg/ha.), which was 3.4, 3.9 and 18.3% higher than the sowing time of 1 st March, 1 st April and 15 th February , respectively during 2017. Among the three varieties, Rama registered highest seed yield (782.7 kg/ha.) and oil content (38.3%) because of significant improvement in yield components and seed quality.

Article InformationA study was conducted to determine the magnitude of associations of traits and genetic divergence among the 64 sesame genotypes. The genotypes were arranged in 8 x 8 simple lattice design and grown in Arjo district, Western Ethiopia during 2013 cropping season. Data were recorded for 12 phenotypic traits and analyzed using SAS software version 9.20 (2002, USA). The results showed that seed yield had positive and significant genotypic and phenotypic correlations with all traits, indicating they are important yield components and can be used for yield improvement in sesame breeding program except for PH and BY. Further analysis by path coefficient method indicated that at genotypic level DM, CFP and HI exerted high positive direct effects on seed yield and strong and positive correlation with seed yield. Similarly, at phenotypic level positive and high direct effects were exerted by CFP, NPB and HI on seed yield and these traits had also strong positive associations with SY. Genetic distance analysis showed that the 64 sesame genotypes were grouped in to 4 clusters and maximum inter cluster square distance (D 2 ) was recorded between cluster I and II followed by cluster I and III. Hence crossing involving cluster I with II and cluster I and III may exhibit high heterotic values and could give transgressive segregants. The principal component analysis revealed that four principal components explained about 66% of the total variation existed among the genotypes. The dominant seed color observed was brown followed by white in the genotypes. The study generally indicated that there was significance genetic variability or divergence among the genotypes. Thus, there is enormous opportunity to use the existing genotypes for direct selection as well as using distant parents for crossing purposes to improve specific traits.
