“…Many previous studies have reported on yield performance and agronomic traits of sesame (Baraki and Berhe,2019;Ofosuhene and Yeboah-Badu, 2010;dos Santos et al, 2018;Matusso and Faruque, 2015;Nadeem et al,2015). However, this study is on yield of sesame under the rain-fed and marginal land conditions.…”

The objectives of this research were to evaluate grain yield, related traits and some agronomic performances of 15 sesame cultivars under rain-fed conditions on marginal land of Northeast in Thailand. The experiments were conducted at two locations; Maha Sarakham and Buriram provinces in Northeast Thailand during the summer of 2018. The fields were arranged in a RCBD with 4 replications and 15 sesame cultivars. Significant differences were observed for all traits at both locations except SPAD chlorophyll meter reading (SCMR) at 90 DAP in Maha Sarakham. Significant differences were found between locations for yield and some of the yield components. It appeared that pod/plant, plant height, number of branches, and plant biomass were the most important components attributing to yield. Harvest index was negatively correlated with yield. Heritability estimates were the highest for plant height (0.88), branches per plant (0.92), pod width (0.95), and pod length (0.89). At Maha Sarakahm, cv. UB3 had the greatest grain yield (1058.03 kg ha-1), and was among the highest for number of branches/plant, plant height, and number of pods/plant, whereas KKU1 had the highest harvest index (43.62%). Mahasarakham60 had the highest SCMR value at 60 and 75 DAP and also total chlorophyll content at 60, 75 and 90 DAP. At Buriram cv. Buriram had the highest number of branches/plant, plant height, SCMR, total chlorophyll content, and number of capsules/plant, but did not have a high grain yield (334.44 kg ha-1). UB1 had the highest grain yield (545.63 kg ha-1) at Buriram. Environmental factors affected agronomic performances and grain yield in sesame grown under the rain-fed condition and marginal land in Thailand. If breeding under various environmental conditions, traits such as plant height and number of branches per plant would achieve the highest gains.

“…The different responses found in the present study are possibly linked to factors of the soil-plantatmosphere relationship, indicating that it is not so simple to understand this relationship in the agricultural environment (Santos et al 2018). It is possible to emphasize this due to the variation in soil characteristics, mainly the organic matter of the soil between the two agricultural harvests.…”

“…The crop of sesame in the 1 st and 2 nd agricultural harvest was carried out at 110 and 105 days after sowing, respectively. Productivity (kg ha -1 ) was determined by weighing the grains of all the plants of the useful area, with 6% water content in the seeds (Grilo Júnior and Azevedo 2013;Santos et al 2018).…”

Nitrogen (N) is an essential macronutrient for plant growth and rate applications can influence the performance of sesame, and when applied in excess can cause nitrogen loss in the environment, and consequently make the cost of production more costly to the producer. Therefore, the objective of this work was to evaluate the efficiency of nitrogen use by different cultivars of irrigated sesame seeds under the edaphoclimatic conditions of the northeastern semi-arid region in two harvests. The experiments were carried out from February to May (1st harvest) and from July to October (2nd harvest) in 2016. The treatments were arranged in a split plot scheme, in which the plots were the five nitrogen doses (0, 30, 60, 90 and 120 kg ha-1), and in the subplots, the four sesame genotypes (CNPA G2, CNPA G3, CNPA G4 and BRS Seda), the design was in randomized complete blocks with four replications. The nitrogen use efficiency assessments evaluated were: agronomic efficiency (AE), physiological efficiency (PE), agrophysiological efficiency (APE), recovery efficiency (RE) and efficiency of use (EU). The rate that provided the greatest efficiency of use was 30 kg ha-1 of N applied. The cultivar BRS Seda had greater efficiency of use in relation to the other cultivars studied. The crop that had better efficiency of use was the 2nd agricultural harvest.

The objective of this work was to evaluate the agro-economic performance of sesame (Sesamum indicum) under nitrogen fertigation in the semiarid region of Northeastern Brazil. The experimental design was randomized complete blocks with four replicates, and the treatments were arranged in a split-plot, where the plots were assigned five N rates (0, 30, 60, 90, and 120 kg ha-1) and the sub-plots were represented by four sesame genotypes ('CNPA G2', 'CNPA G3', 'CNPA G4', and 'BRS Seda'). The following variables were evaluated in two agricultural harvests in 2016: gross and net incomes, rate of return, and profit margin. In both harvests, there was a variation in production costs between N rates. In the second harvest, the highest values of net income were achieved with 120 kg ha-1 N fertigation, being: R$7,428.36 ha-1 for 'CNPA G2', R$8,630.74 ha-1 for 'CNPA G3', R$9,828.64 ha-1 for 'CNPA G4', and R$8,354.06 ha-1 for 'BRS Seda'. Increasing N rates provide an increase in the gross income, net income, rate of return, and profit margin for sesame producers. Fertigation with 120 kg ha-1 N provides the maximum agro-economic performance for sesame, whereas the 'CNPA G4' genotype shows the greatest agro-economic efficiency.
