EVALUATION OF SESAME (SESAMUM INDICUM L.) AS AFFECTED BY NPK FERTILIZER RATES AND COWPEA [VIGNA UNGUICULATA (L.) WALP.] SOWING DATES IN SESAME AND COWPEA INTERCROPPING IN SUDAN SAVANNA, NIGERIA

The study was conducted during 2021 and 2022 rainy seasons; to determine the effects of Sesame (Sesamum indicum L.) as affected by NPK fertilizer rates and Cowpea [Vigna unguiculata (L.) Walp.] sowing dates in sesame and cowpea intercropping in Sudan savanna, Nigeria. The treatments consisted of four rates of NPK fertilizer (0, 50, 100, and 150 kg/ha) and three cowpea sowing dates (simultaneous sowing of cowpea with sesame, sowing of cowpea two weeks after sesame (CSAS) and sowing of cowpea three weeks after sowing the sesame (CSAS), laid out in a factorial arrangement, fitted into a split plot design and replicated three. The NPK fertilizer was assigned to the main plots while cowpea sowing dates were allocated to the sub-plot. Data on growth and yield parameters collected included plant height (cm), number of leaves per plant, leaf area per plant (cm2), number of capsules per plant, 1000 seeds weight (g) and seed yield per hectare (kg/ha ). The data generated from the study were subjected to Analysis of Variance (ANOVA) using Statistix 10.0 and where there is a significant difference; the means were separated using LSD at 5% probability level. Results revealed that NPK fertilizer had significantly improved the growth and yield of sesame. Sesame yield increased with increase in NPK fertilizer rates up to 100 kg ha-1. The highest grain yield obtained for the combined was 934.76 kg/ha. As for the cowpea sowing date, it was noticed that when the cowpea was sown three weeks after sesame, the yield of the sesame increased significantly. The interaction of 100 kg NPK/ha with three weeks after cowpea sowing recorded significantly greater grain yield in both years. Based on the findings, it is concluded that application of 100 kg NPK/ha with three weeks after cowpea sowing is recommended for sesame + cowpea in the Sudan savanna of Nigeria.

Seed and foliar application of nano-selenium improves sesame triacylglycerols and oil yield via photosynthetic pigment and enzymatic and chemical antioxidant enhancement revealed by spectrophotometric, UHPLC-analysis and chemometric modeling

The current study aimed to investigate the effects of plant-mediated selenium nanoparticles (SeNPs) on plant growth, photosynthetic pigments, antioxidant activity, and the triacylglycerol profile of sesame (Sesamum indicum L.). The green synthesis of SeNPs was achieved using garlic extract, resulting in spherical nanoparticles with an average size range of 70–75 nm. Three SeNP treatments (T3, 30 ppm; T4, 40 ppm; and T5, 50 ppm) were applied through seed and foliar spray on six sesame varieties (V1, TS-5; V2, TH-6; V3, Til-18; V4, Niab Millennium; V5, Niab Pearl; and V6, NS-16). All enzymatic antioxidant parameters showed an increase in the treated groups, such as SOD (74.4% in V1 at T4), POD (43% in V5 at T5), APX (62% in V1 at T3), and GPX (31.56% in V3 at T4). CAT showed the highest percentage improvement in T5 for V1, V2, V4, and V5, while V3 and V4 exhibited the highest values at T4. Likewise, seed antioxidant parameters also showed increase in antioxidant activity, highest total phenolic content (6.06 mg GAE/g) was found at T5 treatment with percent increase of 27.41%, but the highest percent increase was found to be at T4 treatments in V1 with increase of 46.83%. Percent oil yield was also noted to be higher as highest percent (60%) oil yield was obtained at T4 treatment in V3. Ultra High Performance Mass-Spectrometry (UHPLC-MS) analysis and chemometric modeling suggested a total of 10 triacylglycerol (TG) biomarkers separating untreated groups, with higher relative abundance values at T4 and T5 treatments compared to control. PCA and correlation analysis showed clustering of untreated groups from T4 and T5, which suggests that these two treatments result in higher accumulation of oil. A generalized linear model with ANOVA showed a highly significant impact of treatments on all the growth and oil parameters, with significance involvement of varieties. The interaction between variety and treatment showed no significant effect on the growth and oil biomarkers of sesame. However, it can be concluded that the T4 and T5 treatments (40 ppm and 50 ppm) of SeNPs, applied through seed and foliar methods, have a strong influence on the overall growth and oil yield of sesame. This warrants further transcriptomic and molecular analysis to gain deeper insight into the mechanisms of action of SeNPs.

Influence of Liquid Biofertilizers on Growth and Yield of Sesame (Sesamum indicum L.)

A field experiment was conducted at S.V. Agricultural College Farm, Tirupati during summer, 2024 to study the influence of liquid bio fertilizers and different levels of fertilizers on growth and yield of sesame. Results revealed that the application of 100% RDF + seed treatment + soil application of liquid bio fertilizers (Azospirillum, PSB and KSB) reported higher plant height( 99 cm), leaf area index(1.72), dry matter accumulation (3341 kg ha-1), seed (945 kg ha-1) and stalk (1890 kg ha-1) yield as compared to other treatments. The grain yield of sesame with100% RDF + seed treatment + soil application of liquid bio fertilizers (Azospirillum, PSB and KSB) was enhanced by 26.5% and 24.3% when compared to the 100% RDF alone. The lowest seed yield (380 kg ha-1) and stalk yield (830 kg ha-1) was registered with absolute control.

Integrated uses of organic and inorganic fertilisers to increase sesame productivity on coastal sand fields

Sesame is recognised as a valuable oil plant with potential health benefits due to its disease mitigating properties. It shows exceptional growth rates in light soil types, such as sandy beach soils which are often deemed infertile. To address the issue, it is necessary to apply eco-friendly fertilisers derived from animal manure. Consequently, research has focused on performance evaluation over two growing seasons, namely the dry and rainy seasons, on coastal sandy soils. Employing a split-plot design across three replicates, the study investigated the influence of planting time and cultivar on the growth and yield of sesame. The study aimed to assess the impact of mixed fertiliser application timing on sesame growth and yield, focusing on both quantitative and qualitative parameters across the rainy and dry seasons. Results indicated that applying a mixture comprising chicken manure and inorganic fertiliser at the planting time significantly affected several growth parameters. These included plant height, chlorophyll content, flowering time, number of branches, net assimilation rate, root volume, and total sesame oil content, particularly in the dry season. Specifically, employing a dosage of 24.75 g of inorganic NPK fertiliser, comprising 1.45 g of nitrogen, 0.74 g of phosphorus, and 1.25 g of potassium per plant at planting time during the dry season, demonstrated the most favourable outcomes in terms of growth, yield components, and soil fertility. This approach also yielded a remarkable 54.51% oil content in the cultivar ‘Sbr-1’.

High-density genetic map construction and QTL mapping to identify genes for blight defense- and yield-related traits in sesame (Sesamum indicum L.).

Sesame (Sesamum indicum L.) is an important oilseed crop widely cultivated in subtropical and tropical areas. Low genetic yield potential and susceptibility to disease contribute to low productivity in sesame. However, the genetic basis of sesame yield- and disease-related traits remains unclear. Here, we represent the construction of a high-density bin map of sesame using whole genome sequencing of an F2 population derived from 'Yizhi' and 'Mingdeng Zhima'. A total of 2766 Bins were categorized into 13 linkage groups. Thirteen significant QTLs were identified, including ten QTLs related to yield, two QTLs related to Sesame Fusarium wilt (SFW) disease, and one QTL related to seed color. Among these QTLs, we found that SFW-QTL1.1 and SFW-QTL1.2 were major QTLs related to Fusarium wilt disease, explaining more than 20% of the phenotypic variation with LOD > 6. SCC-QTL1.1 was related to seed coat color, explaining 52% of the phenotypic variation with LOD equal to 25.3. This suggests that seed color traits were controlled by a major QTL. Candidate genes related to Fusarium wilt disease and seed color in the QTLs were annotated. We discovered a significant enrichment of genes associated with resistance to late blight. These genes could be spectral disease resistance genes and may have a role in the regulation of Fusarium wilt disease resistance. Our study will benefit the implementation of marker-assisted selection (MAS) for the genetic improvement of disease resistance and yield-related traits in sesame.

Effects of soil amendments and coverings on the kenaf yield and soil physicochemical properties in saline-alkali land

In order to investigate the effects of various treatments on the growth of kenaf in saline soil, this study employed a comprehensive experimental design incorporating a dual approach of soil amendment and mulching techniques. Soil treatment of saline and alkaline land, as well as biological material mulching treatment after sowing kenaf, were conducted. The growth dynamics of kenaf were assessed before the mid-term investigation, and the harvest period was examined. Soil physicochemical properties were measured and analysed at different periods. The results show that in the analysis of red sesame yield traits, the differences mainly appeared between soil treatments. There is no significant difference between the different mulching treatments within each soil treatment. In the mid-term study, significant differences were observed in kenaf plant height. Plant height was the most affected by soil conditioners, while other yield traits did not show significant variations. During harvest, only stem thickness and dry weight of a single plant did not show significant differences, whereas other yield traits did. The application of soil conditioners resulted in a 58.15% increase in dry hull yield compared to organic fertilizers and a 22.66% increase compared to regular fertilizers. Soil conditioners also led to higher levels of effective phosphorus, quick-acting potassium, organic matter, and total nitrogen throughout the kenaf growth period compared to organic and regular fertilizers. This is beneficial for enhancing soil quality and reducing soil alkalinity. Combined with the results of kenaf yield and soil physical and chemical properties analysis, it has been proven that the application of soil conditioner has the best effect, followed by the application of compound fertilizer, with organic fertilizer treatment being the least effective.

Productivity and profitability of sesame (Sesamum indicum)- chickpea (Cicer arietinum) organic cropping system as influenced by nutrition and planting geometry

An experiment was conducted during 2021–22 and 2022–23 at the research farm of Punjab Agricultural University, Ludhiana, Punjab to optimize organic nutrition and planting geometry for improved productivity and profitability of sesame (Sesamum indicum L.)-chickpea (Cicer arietinum L.) organic cropping system. The experiment was conducted in a split-plot design (SPD) with three organic nutrition management practices in main plots, viz. Application of farmyard manure (FYM) to supply recommended doses of nitrogen (RDN) i.e. 52.5 kg/ha for sesame and 15 kg/ha for chickpea; Application of FYM to supply RDN + natural farming concoctions (NFCs) i.e. beejamrit, ghanjeevamrit and jeevamrit; and Control i.e. without application of FYM and NFCs. In sub-plots, four planting geometries were evaluated for sesame (30 cm × 15 cm, 45 cm × 10 cm, 60 cm × 10 cm, and paired rows) and chickpea (30 cm × 10 cm, 45 cm × 7 cm, 60 cm × 7 cm, and bed planting). Application of FYM significantly improved growth, yield attributes and seed yield of sesame and chickpea compared to the control, whereas the addition of NFCs along with FYM did not further enhance these parameters significantly during both the years. Paired row sowing followed by (fb) bed formation led to notably higher seed yield in sesame, while chickpea sown at 30 cm × 10 cm spacing achieved the highest seed yield, statistically equivalent to sowing at 45 cm × 7 cm and bed planting. The most productive system, recorded a sesame equivalent yield of 18.1 q/ha, net returns of ₹1,06,224/ha, and a benefit cost (B:C) ratio of 1.51, achieved through paired row sowing of sesame and bed planting of chickpea. Conclusively, the optimized organic nutrition and planting geometry significantly enhanced the productivity and profitability of the sesame-chickpea cropping system, with paired row sowing and bed planting emerging as the most effective strategies.

Refining flowering date enhances sesame yield independently of day-length

BackgroundThe transition from vegetative to reproductive growth is a key factor in yield maximization. Sesame (Sesamum indicum), an indeterminate short-day oilseed crop, is rapidly being introduced into new cultivation areas. Thus, decoding its flowering mechanism is necessary to facilitate adaptation to environmental conditions. In the current study, we uncover the effect of day-length on flowering and yield components using F2\\documentclass[12pt]{minimal} \\usepackage{amsmath} \\usepackage{wasysym} \\usepackage{amsfonts} \\usepackage{amssymb} \\usepackage{amsbsy} \\usepackage{mathrsfs} \\usepackage{upgreek} \\setlength{\\oddsidemargin}{-69pt} \\begin{document}$$_2$$\\end{document} populations segregating for previously identified quantitative trait loci (Si_DTF QTL) confirming these traits.ResultsGenerally, day-length affected all phenotypic traits, with short-day preceding days to flowering and reducing yield components. Interestingly, the average days to flowering required for yield maximization was 50 to 55 days, regardless of day-length. In addition, we found that Si_DTF QTL is more associated with seed-yield and yield components than with days to flowering. A bulk-segregation analysis was applied to identify additional QTL differing in allele frequencies between early and late flowering under both day-length conditions. Candidate genes mining within the identified major QTL intervals revealed two flowering-related genes with different expression levels between the parental lines, indicating their contribution to sesame flowering regulation.ConclusionsOur findings demonstrate the essential role of flowering date on yield components and will serve as a basis for future sesame breeding.

Assessment of cluster front line demonstration on yield and economics of summer sesame

Sesame is one of the most important oilseed crops which play a major role in increasing the income of small and marginal farmers of the Kutch region of Gujarat. To promote the improved cultivation technology of sesame with high yielding variety ‘GT4’ and ‘GJT5’, 123 cluster front line demonstrations (CFLDs) were conducted in 63.2 ha area during summer, at ICAR-CAZRI, Krishi Vigyan Kendra, Kukma, Bhuj, Kachchh, Gujarat during summer 2017 to 2020. The four years data revealed that the average yield increased to 16.34% over the existing practice due to adoption of improved practice. The average technology gap, extension gap and technology index were 270.5 kg/ha, 121 kg/ha and 24.95%, respectively. Furthermore, the economics of the demonstrations and farmers practice showed an increased net return of ₹39,319/ha with benefit: cost ratio (BCR) of 2.47 in demonstrated plots over conventional plots where it was ₹30,700/ha and 2.19, respectively. By conducting front line demonstration of the proven technologies, yield potential of sesame crop could be enhanced to a greater extent with increase in the income level of the farming community.

The influence of climate change on the sesame yield in North Gondar, North Ethiopia: Application Autoregressive Distributed Lag (ARDL) time series model

Sesame is a major annual oil crop that is grown practically everywhere in tropical and subtropical Asia, as well as Africa, for its very nutritious and tasty seeds. Rising temperatures, droughts, floods, desertification, and weather all have a significant impact on agricultural production, particularly in developing countries like Ethiopia. Therefore, the main objective of this study is to examine the influence of climate change on the sesame yield in North Gondar, North Ethiopia, by using the autoregressive distributed Lag (ARDL) time series model. This study employed climate data from the Bahirdar Agrometeorological Center and secondary data on sesame production from the Ethiopian Statistical Service, spanning 36 years, from 1987 to 2023. Autoregressive Distributed LAG (ARDL) includes diagnostic tests for both short- and long-term autoregressive models. The results for the long-run and short-run elastic coefficients show a significant positive association between temperatures and sesame yield. Sesame yield and rainfall have a significant negative long-run and short-run relationship in North Gondar, North Ethiopia. ARDL results confirm that temperature and rainfall have significant effects on sesame productivity. Temperature had a considerable favorable effect on sesamen production, but rainfall had a negative effect in North Gondar, Ethiopia. Based on the evidence acquired from our study, we made several policy recommendations and suggestions to government officials, policymakers, new technologies, researchers, policy development planners, and other stakeholders in order to develop or implement new technology to halt its production and direct adaptation measures in light of the certainty of global warming and the characteristics of climate-dependent agricultural production.

Study Design: Randomized Block Design with three replications. Place and Duration of Study: During 2018 and 2019, this experiment was carried out at the Odisha University of Agriculture and Technology's Regional Research and Technology Transfer Station, which is located in Mahisapat, Dhenkanal district, Mid Central Table Land Zone, Odisha. Methodology: The treatments were T1- STBFR (S control), T2- STBFR + 30 kg ha-1 S from Ammonium Phosphate Sulphate, T3- STBFR + 40 kg ha-1 S from Ammonium Phosphate Sulphate, T4- STBFR + 30 kg ha-1 S from Gypsum, T5- STBFR + 40 kg ha-1 S from Gypsum, T6- STBFR + 30 kg ha-1 S from SSP, T7- STBFR + 40 kg ha-1 S from SSP. Results: Among seven treatments, T7 (STBFR along with 40 kg ha-1 S from SSP) was superior among all the sources and doses w.r.t. yield components and yield. The quality parameters like oil content under different sulphur fertilization was found to be maximum with STBFR along with 40 kg ha-1 S from SSP. Highest total nutrient uptake in terms of N, P, K and S of 55, 26, 37 and 5 kg/ha was recorded with the same treatment. Conclusion: Sulphur fertilization (T7) in the acid Alfisols of Odisha exhibited improved yield, oil content and nutrient uptake in sesame.

Estimating yield stability and predicting the response of sesame genotypes to climate change using the SALTMED model

AbstractClimate change (CC) could lead to many crises. Therefore, increasing the number of cultivated varieties represents a low‐cost factor in confronting this problem. The effect of the genotype × environment (G × E) interaction on yield stability was estimated for 28 new sesame lines in the Beni Suwef, El‐Beheira and El‐Menoufia governorates in Egypt across 15 environments from 2019 to 2022 using AMMI analysis. The SALTMED model was used to predict the yield of sesame plants under five increasing air temperature scenarios (CC factor) to obtain future projections of sesame yield to determine the lines that are most genetically stable and facing CC. Variance analysis revealed significant differences in yield between the G and E groups and between the G × E interaction group. Fifteen genotypes yielded better control, and C6.4, C5.8 and C9.6 were selected as genetically stable according to AMMI analysis. The SALTMED model predicted that the yields of lines C3.8 and C6.2 were not affected under the high‐temperature scenarios across the three governorates, moreover lines C1.8, C2.3, and, C6.12 productions were not affected under Beni Suwef and El‐Beheira governorates. of lines C1.8, C2.3 and C6.12 were also not affected by the Beni Suwef or El‐Beheira governorates. It is now possible to establish a hybridization programme in sesame that combines parents with high productivity and high resilience to CC.

Effect of Mineral Fertilizer on Yield, Quality and Nutrient Uptake of Black Sesame [Sesamum radiatum (L.)

A field study aimed to evolve efficient nutrient management for improving yield and quality of sesamum was conducted during pre-rabi season of 2022. The experiment was laid out in a factorial randomized block design replicated thrice with twelve treatments. Treatments consisting of two levels of nitrogen (25 and 50 kg/ha), two levels of phosphorus (12.5 and 25 kg/ha) and three levels of sulphur (0, 20 and 30 kg/ha). Seed and stover yield as well as total nutrient uptake were recorded significantly higher with the application of 50 kg/ha N, 25 kg/ha P and 30 kg/ha S. The application of 50 N and 30 kg S was recorded significantly higher oil content and oil yield over the rest of the nitrogen and sulphur levels. N content in seed (3.13%) and stover (1.226%) were found significantly influenced by 50 kg/ha N. Phosphorus @ 25 kg/ha was recorded significantly higher P content in seed (0.493 %) and stover (0.392%).S content in seed (0.325%) and stover (0.171%) were found significantly influenced by 50 kg/ha S. Significantly higher available nitrogen (281.22 kg/ha) was found under application of nitrogen @ 50 kg/ha. Significantly the higher residual phosphorus (28.81 kg/ha) was obtained with the application of 25 kg P/ha. Significantly the higher residual sulphur (7.63 mg/kg) was obtained with the application of 30 kg S/ha.

Enhancing Sesame Yield in Arid Conditions through NPK Fertilizer Optimization

Sesame, an important oilseed crop and valuable source of protein, plays a central role in global agriculture. This study, conducted during the 2021-2022 Kharif season at Karor Adaptive Research Farm (ARF), Layyah, Pakistan, aimed to optimize the use of NPK (nitrogen, phosphorus and potassium) fertilizers to increase sesame yield under dry conditions. Our research aimed to determine the most effective application rates of NPK fertilizer (34:24:12) kg/acre for sesame variety TH-6 in the region, consistent with the objectives of maximizing sesame yield and biomass accumulation. The experimental design RCBD included multiple treatments, with meticulous attention to plot sizes, replicates, and robust data collection and analysis methods. These measures ensure the reliability of our results and their potential applicability to similar agroclimatic conditions. The use of NPK fertilizer at the rate of (113:113:60) kg ha-1 in ARF gave promising results. A maximum grain yield of 765.3 kg ha-1 was observed in 2021, exceeding the yield of 738.6 kg ha-1 in 2022. Similarly, the use of NPK (113:113:60) kg ha-1 in a farmer's field resulted in a maximum grain yield of 828.6 kg ha-1 in 2021, as opposed to 702.6 kg ha-1 in 2022. These results highlight the potential of NPK fertilizer application combined with optimal field practices to increase sesame yield and its components under the challenging agro-climatic conditions of Karor, Layyah. The discussion interprets the results and emphasizes the importance of NPK fertilizers for sesame cultivation. Although our primary focus is not on climate discussions, the consistent methodology in both years, from sowing to harvesting, revealed significant differences in yield and growth parameters, leading to climate change being considered as a potential contributing factor. This study shows that the application of NPK fertilizer at the rate of (113:113:60) kg ha-1 can significantly increase sesame yield under adverse conditions.

Nutrient Uptake and Quality of Sesame (Sesamum indicum L.) as Influenced by Sulphur and Boron

At the Agronomy Field Unit, ZARS, UAS, GKVK, Bengaluru, a field experiment was carried out in kharif 2017 to examine the impact of sulphur and boron on sesame yield and quality (Sesamum indicum L.). Twelve treatments were reproduced three times in the experiment, which was set up using a factorial RCBD design. The application of the recommended dose of fertilisers (RDF) with 30 kg sulphur and 5 kg borax per ha resulted in significantly higher seed yield (470.00 kg ha-1) and stalk yield (3126 kg ha-1) than the application of the recommended dose of fertilisers with 40 and 5, 40 and 2.5, 30 and 5 kg sulphur and borax per ha (461.56 and 2826.67, 455.13 and 2733.33, 445.67 and 2626.67 kg per ha, respectively). Increased nutrient uptake of nitrogen (40.23 kg ha-1) phosphorus (15.01 kg ha-1) potassium (45.23 kg ha-1) sulphur (13 kg ha-1) and boron (162.4 ppm) was primarily responsible for increased seed and stalk yield. The application of the recommended dose of fertilisers with 40 kg sulphur and 5 kg borax per ha resulted in higher seed protein (10.72%). This matched RDF + 40 kg sulphur + 2.5 kg borax (10.66%). RDF+30 kg sulphur + 5 kg borax per ha produced the highest C: B ratio (3.5).

Present study was carried out in major sesame growing areas of Northern Telangana zone in districts namely; Nizamabad, Jagtial, Nirmal and Kamareddy. The main objective of this study is to assess the soil quality and to find out the relation between sesame yield and soil quality index. Based on the seed yield data of sesame, the above-mentioned districts were divided into high, medium and low productivity zones. 50 samples from each productivity zone with a total of 150 surface soil samples (0-15 cm were collected and analysed for various physical, physico-chemical, chemical and biological properties. Physical properties included texture, bulk density and water holding capacity. Physico-chemical properties like pH, EC and organic carbon were analysed. Chemical properties of soil namely available nitrogen, available phosphorus, available potassium, available sulphur, exchangeable bases like exchangeable calcium and magnesium, potassium and sodium, available micronutrients like iron, copper, manganese and zinc were analysed. Biological properties like urease, acid and alkaline phosphatase and labile carbon were analysed. Principal component analysis, minimum dataset was derived which contained available nitrogen, sand, pH, available phosphorus, exchangeable calcium and magnesium and urease with 70.81% variance. These are identified as the key indicators of soil quality. Mean soil quality index values were 0.669, 0.549 and 0.443 for high, medium and low sesame productivity zones respectively and is in the order of high>medium>low sesame productivity zones. Percent contribution of MDS to SQI are in the order of, available nitrogen (44.44%> pH (16.85% >exchangeable calcium (9.87%> exchangeable magnesium (8.89%> urease (7.86%> available phosphorus (7.38% > sand (4.89%. This study concluded that the SQI was more significantly positively correlated with sesame yield, which revealed that soil variables from the minimum data set had biological significance and effectively evaluated the status of the sesame growing soils of Northern Telangana Zone.
