Abstract

In Bangladesh, sesame suffers from water-logging during its growing period. Multi-year and multi-location field trials were carried out to study the effect of different durations of water-logging at different growth stages on seed yield of sesame. From two years results, it is revealed that the effects of water-logging during a particular growth stage or particular duration of water-logging on seed yield depends on pre- and/or post water-logging from the rainfall. Differential effects of the cultivars were also observed. The cultivar Binatil-2 and Binatil-3 showed reasonable seed yield under water-logging at flowering and mid pod-formation stages for 24 to36 hours.

Summary

Introduction

Water-logging, drought and salinity stresses are the major adverse environmental conditions that limits plant growth (Dossa et al, 2017; Ali, 2017; Mila et al, 2017). It is reported that sesame is drought tolerant but susceptible to water-logging (Wang et al, 2016). Sesame seed oil is a rich source of nutrients. Sesame is one of the major oilseed crops that is cultivated during the Kharif season (Mid February to June) in Bangladesh. The cultivated area of sesame in Bangladesh is low. The reason is low yield (which is about 0.91 t/ha, national average) (BBS, 2017) and sensitivity of the cultivars to water-logging. In order to increase the production of sesame, emphasis should be given to cultivate high yielding varieties applying different modern management practices with special consideration to water-logging (Sarkar et al, 2016; Wang et al, 2016)
