    Background: This study was conducted to determine the effects of microbial fertilizer and vermicompost applications on the yield and yield related parameters of broad beans (Vicia faba L.) under zero chemical fertilizer applied conditions. Trial area was a highland remote to sea under Mediterranean climate in South Eastern Anatolia of Turkey. It is located in fertile crescent and 180 km away to Karacadag Mountains (Diyarbakir) where Einkorn wheat (Aegilops monococcum L.) was first cultivated in history approximately ten thousand years ago. The broad bean was also among the founder crops of the Near East including the trial location. Methods: Rhizobium leguminosarum inoculant were used as microbial fertilizer in the experiments. Applied vermicompost doses were 0, 400, 800 and 1200 kg ha(-1). The trials was conducted for two years and replicated thrice in a randomized block deign. Conclusion: Application of vermicompost was found significantly effective on the plant height, first pod height, number of pods per plant, number of seeds per pod, 100 grain weight and grain yield. Aapplication of 800 kg ha(-1) and 120 kg ha(-1) vermicompost along with Rhizobium leguminosarum inoculation was found superior for grain yield.

    Enhancement of Root System Architecture, Seedling Growth, and Germination in Lentil under Salinity Stress by Seed Priming with Silicon and Salicylic Acid
    (Hard, 2023) Ceritoglu, Mustafa; Erman, Murat; Cig, Fatih; Ceritoglu, Figen; Ucar, Ozge; Soysal, Sipan; EL Sabagh, Ayman
    To deal with increasing salinization, plants show an array of responses such as root system architecture remodelling, thereby enhancing stress tolerance. Although various chemical, molecular and genetic techniques such that generally expensive and difficult applications are used to enhance stress tolerance, out of them, seed priming with suitable substrates is an easy-applicable and cost-effective treatment. The experiment aimed to evaluate the effects of salicylic acid (SA), silicon (Si), and sodium chloride (NaCl) priming on lentil seed germination parameters, seedling development, and root system architecture. In 2022, the experiment was carried out in the Field Crops Department laboratory at Siirt University in Turkey. Petri and pot investigations were part of the two stages of the experiment. Three concentrations of NaCl and priming treatments were utilized. Germination characteristics were impeded by rising saline levels. But seed priming, which boosted uniformity of germination by 50% as compared to unprimed seeds under saline stress, enhanced germination characteristics. A pot experiment revealed that the dry matter accumulation in roots was reduced by 24.6% due to salt stress. Si priming increased number of lateral roots by 32.6% compared to control seeds, whereas salt stress lowered it by 22.8%. The total length of lateral roots (TLLR) and mean length of lateral roots (MLLR) were inhibited by salinity stress by 75% and 63, respectively. Total root area was reduced by salinity stress by almost 70%, although seed priming increased it by as much as 29.3%. The SA and Si priming treatments improved germination stage and induced seedling growth by reducing salinity stress via more effective shoot development and root system architecture. In conclusion, seed priming with SA and Si is an affordable and sustainable method for reducing salt stress in lentil farming.

    Screening of lentil genotypes during germination and early growth stages under PEG-induced drought stress
    (Inst Investigaciones Agropecuarias - Inia, 2024) Cig, Fatih; Erman, Murat; EL Sabagh, Ayman; Ceritoglu, Mustafa; Soysal, Sipan; Ucar, Ozge; Ceritoglu, Figen
    The objective of this experiment was to determine drought tolerance exhibited by lentil lines developed by the International Center for Agricultural Research in the Dry Areas (ICARDA) in an artificial environment, and to investigate the relationships between traits with various methods. This experiment examined 15 traits of 21 lentil (Lens culinaris Medik.) accessions grown under artificial drought stress created with polyethylene glycol (PEG)-6000 (0%, 10%, 15% and 20%) concentrations during germination and early seedling stages. Germination characteristics, seedling developmental properties and root system architecture traits were investigated to observed the impacts of drought stress. The originality lies in enabling the identification of drought-tolerant and sensitive genotypes through a brief and practical research method, while shedding light on the key traits by principal component analysis. The first two PCs explained 22.9% and 31.7% (total 54.6%) under optimal conditions while they described 14% and 58.3% (total 72.3%) under PEG-induced drought conditions, respectively. Variation in PC1 was mostly contributed by positive coefficients of germination index, uniformity of germination and germination energy, and negative coefficients of mean germination time. Variation in PC2 was mostly contributed by positive coefficients of seedling vigor index, root fresh weight and root dry weight. 'Tigris', G3664 and G3840 exhibited higher performance in terms of germination characteristics, while G3710, G3829 and G3840 produced higher DM accumulation, total biomass and lateral roots. Overall, PC-biplot denoted that selection based on germination index and seedling vigor index at germination and seedling stages would improve drought tolerance. In conclusion, genotypes G3840 and G3664 were identified as drought-tolerant, whereas genotypes G35, G3659, G3759, G3837, and G3844 were classified as drought-sensitive. In addition, G3664, G3840 and G3710 exhibited the highest stress tolerance index (STI) under artificial drought conditions.

    (Agricultural Research Communication Centre, 2021) Ucar, Ozge
    Background: This study was conducted in 2016-2017 to determine the effects of Mesorhizobium ciceri inoculation and different doses of vermicompost applications on the yield components and yield of chickpea under semi-arid Mediterranean highland condition of Turkey. Methods: Mesorhizobium ciceri inoculant were applied to seeds (at 10(8) cfu bacteria per seed dose) as microbial fertilizer in the experiments. Vermicompost doses were 0, 1000, 2000 and 3000 kg ha(-1). The trials were set up with three replications according to the randomized complete blocks design. Conclusion: Plant height, first pod height, pod number per plant, number of seeds per plant, 100 grain weight and grain yield were determined as 56.1-61.9 cm, 29.4-34.9 cm, 31.4-46.3 pods plant(-1), 32.9-44.0 seed plant(-1), 30.4-37.4 g and 1463-2072 kg ha(-1), respectively. Co-application of 1000 kg ha(-1) vermicompost with Mesorhizobium ciceri inoculation produced the highest values for all examined parameters for both years. Further applications of vermicompost reduced yield and related components. Control parcels and excess vermicompost applications (2000 and 3000 kg ha(-1)) produced lowest values. Mesorhizobium ciceri inoculation produced medium values between Co-application of 1000 kg ha(-1) vermicompost with Mesorhizobium ciceri and control and excess vermicompost applied conditions. In conclusion, use of Mesorhizobium ciceri + 1000 kg ha(-1) vermicompost was recommended in chickpea cultivation for maximum yield in the ecological conditions of Siirt province of Turkey or in similar ecologies.
