“…The sesame cultivars revealed differences in the expression of their morphological characteristics due to genetic variability and the prevailing environmental factors. Similar explanations were suggested by the previous findings [24,25]. Among the branched cultivars, SG-30 and TH-5 produced the highest seed yield because of their dominant genetic ability and yield stability in all growing conditions, mainly due to producing a higher number of capsules plant −1 .…”

Sesame cultivars perform differently in various environments comprising specific locations and years. Micronutrient fertilizers increase crop yields and can enhance resistance to environmental hazards and contribute to potential yield. For assessing the effect of environment and micronutrients, field experiments were carried out at three different locations (BARI, URF and NARC) of Pothwar region, Pakistan, in two succeeding years (2014, 2015). Four sesame cultivars and three micronutrients (Zn, B and Mn) with a control treatment were used in RCB design with a split-plot procedure and four replications. The results showed significant differences in the main effects of all tested factors (cultivars, micronutrients, locations and years). Maximum mean values of plant height, capsules plant−1, biomass yield and seed yield were recorded for SG-30, while TH-6 was the lowest for these parameters. Maximum mean values of capsule length, capsule weight, seeds capsules−1 and the weight of 1000 seeds were recorded for TH-6 but vice versa for SG-30. Maximum capsule length and seeds capsule−1 were observed at NARC, while other growth and yield attributes were maximum at BARI and URF, including biomass yield and seed yield. The interactive effect of cultivar × location × year was highly significant for all growth and yield traits except capsule length. Sesame cultivars revealed a differential response for all traits at three locations during both years. Application of micronutrients significantly augmented all growth and yield features of sesame. Micronutrient fertilizers (i.e., ZnSO4 at 10 kg ha−1, borax at 10 kg ha−1 and MnSO4 at 5 kg ha−1) would increase yield and yield-attributing traits in low- or medium-precipitation areas where suitable cultivars have been designated.

“…If the stomatal conductance is low there will be faster rate of intercellular CO 2 utilization compared to the rate of CO 2 uptake through stomata. This result is in agreement with the studies made by Akter et al, (2016) [2] in sesame. The maximum values of internal CO 2 were documented for RT-346 (358 ppm) followed by RT-127 (346 ppm) and TKG-22 (338 ppm).…”

A field experiment was conducted to evaluate the performance of ten sesame varieties viz, RT-346, RT-351, RT-127, GT-10, TKG-22, Swetha til, JCSDT-26, DS-1, YLM-66 and KMS-59 for physiological, biochemical and yield traits using randomized block design with three replications under rainfed conditions. Results showed that the varieties significantly differed for the physiological parameters such as photosynthetic rate, stomatal conductance, internal CO2 concentration where as transpiration rate remain non-significant. Variety JCSDT-26 recorded high photosynthetic rate which is positively correlated with the seed yield and low transpiration rate and internal CO2 concentration which are negatively correlated with the seed yield. The highest value of oil content was observed in JCSDT-26 (48.5 %) because of its white seed colour. The maximum value of palmitic acid was also recorded in the variety JCSDT-26 (10.57%). Hence, the variety JCSDT-26 is considered as suitable for cultivation under the rainfed conditions.

Sulphur is a component of plant amino acids, proteins, vitamins, and enzyme structures which influence the productivity of oil seed and total oil content. The experiment was conducted to find out the effect of sulphur on the seed yield and oil content of sesame in Bangladesh. The experiment comprised three varieties of sesame viz. Binatil-2, Binatil-3 and BARI Til-4 and six levels of sulphur (S) viz. 0, 10, 20, 30, 40 and 50 kg S ha–1. The experiment was laid out in a randomized complete block design with three replications. Dry matter production, crop characters, yield components, seed yield and oil content were significantly influenced by variety, level of sulphur and their interaction. The highest dry matter production plant–1 at 50 DAS (17.56 g), plant height (101.3 cm), number of branches plant–1 (3.66), number of pods plant-1 (41.56), number of seeds pod-1 (58.83), seed yield (747.2 kg ha-1), stover yield (2243.0 kg ha–1) and oil content (40.03%) were obtained in BARI Til-4 while the corresponding lowest values of all parameters were recorded in Binatil-2. In case of sulphur application, the highest dry matter production plant–1 at 50 DAS (20.81 g), plant height (109.7 cm), number of branches plant–1 (3.87), number of pods plant–1 (46.13), number of seeds pod-1 (56.67), seed yield (800.0 kg ha–1), stover yield (2787 kg ha–1 ) and oil content (43.97%) were obtained when crop was fertilized with 30 kg S ha–1 while the lowest seed yield (502.2 kg ha–1), stover yield (1550.0 kg ha–1) and oil content (32.80%) were obtained in control (0 kg S ha–1). BARI Til-4 fertilized with 30 kg S ha–1 produced the highest dry matter plant–1 at 50 DAS (24.80 g), number of pods plant–1 (51.13), seeds pod–1 (62.0) and seed yield (1011.0 kg ha–1). The highest oil content (43.97%) was also recorded in BARI Til-4 fertilized with 30 kg S ha–1, which was as good as that of BARI Til-4 fertilized with 40 kg S ha–1. Therefore, BARI Til-4 fertilized with 30 kg S ha–1 can be considered as a promising practice in respect of seed yield and oil content of sesame in Bangladesh. J. Bangladesh Agril.
