(Scibulcom Ltd., 2015) Dogan, Y.; Doğan, Yusuf
Chickpea has significant amounts of all the essential amino acids except sulphur-containing types. It was found that chickpea is a rich source of protein and minerals. The experiments were conducted in a Randomised Complete Block Design with three replications 2013 and 2014 years in South-Eastern Turkey. A total of fifteen varieties, lines and populations were used as materials. In the study were investigated different parameters such as amino acids of protein, seed yield, protein and fat rate in seed, phosphorus, potassium, calcium, manganese, zinc, copper and iron contents and of seeds. The essential amino acid leucine (8.43 mg/100 g in 2013 and 8.59 mg/100 g in 2014) was found in highest concentration, followed by lysine (7.14 mg/100 g in 2013 and 7.27 mg/100 g in 2014) and phenylalanine (5.99 mg/100 g in 2013 and 6.07 mg/100 g in 2014) in the chickpea. Mineral composition of chickpea genotypes showed that they contribute sufficient amount of Ca, P, K, Cu, Zn and Mg in human diets to meet the recommended dietary allowance. According to the average of two years, the highest grain yield was obtained from Diyar-95 variety with 1618 kg ha–1, the lowest grain yield was obtained from M-1 local population with 1104 kg ha–1. © 2015, Scibulcom Ltd.

(Corvinus University of Budapest, 2019) Dogan, Y.; Togay, N.; Togay, Y.; Doğan, Yusuf
The aim of this study was to determine the most suitable irrigation schedules and sources of manure for maize under Mardin ecological conditions. For this purpose, four sources of fertilizer and three irrigation schedules were applied in hybrid maize cultivar to find out their effects on the yield and yield factors in the years of 2014 and 2015. The study used a randomized complete block with split block design with 3 replications. In the study, significant differences were determined on traits at the level of 1% and 5%. The plant height, first cob height, cob length, number of seeds per cob, cob yield, 1000 seed weight, seed yield per unit, hectoliter, protein and oil ratio in seed, Mg, K, Fe, Ni, Cu, Zn, Mn, Na, Ca content of seeds were significantly influenced by irrigation schedules and sources of fertilizer for two years. The highest values were obtained from chicken manure with 9646 kg ha-1 in the first year and 11019 kg ha-1 in the second year, whereas the lowest values were obtained from control with 6363 and 6662 kg ha-1 for the first year and the second, respectively. But the difference between 180-80 kg N-P2O5 - ha-1 and chicken manure was not statistically significant in the second year. According to the irrigation schedules, the grain yield ranged between 6386-10678 kg/ha in the first year and 7575-12133 kg ha-1 in the second year. The lowest grain yield per area was from the four-irrigation application, whereas the highest values were obtained from the six-irrigation application. The results of the study showed that grain yield and nutrient level of corn seeds increased, depending on irrigation time and number. © 2019, ALÖKI Kft., Budapest, Hungary.
Investigating the Quality of Durum Wheat Landraces and Determination of Parents To Use in Breeding Programs
(Corvinus Univ Budapest, 2019) Kendal, E.; Eren, A.; Dogan, Y.; Oral, E.; Koyuncu, M.; Doğan, Yusuf
The study was conducted to evaluate the quality of durum wheat grain. For this reason, genetic resources are crucial for the identification of parents and the enrichment of the gene pool that can be used in the development of new varieties for better nutrition of people. For this purpose, 131 populations of landraces, 9 promising line and 5 new varieties were used. The experiment was set up in randomized blocks with 7 replications, according to the augmented (increased) experimental design in 2015-2016 growing season. In the study, we examined total nitrogen content, protein ratio, CIE (Commission Internationale Eclairage) wheat color analysis (L* brightness, b* jaundice, a* redness) of 145 genotypes of durum wheat seeds. According to analysis of variance, highly significant differences (P < 0.05 or P < 0.01) were determined for total nitrogen, protein content and CIE L* value, while differences were not significant for b* value and a* value. The superiority of the genotypes was determined by the first two principal components (IPC1 (principle component) and IPC2) in order to create a two-dimensional GT biplot. The sum squares of the first two components were accounted by 45.34% (PC1) and 40.03% (PC2) for genotypes. The GT (genotype x trait) biplot indicated that 9 (nine) sectors occurred among genotypes and quality parameters. On the other hand, three groups occurred among the quality parameters based on the genotypes. The scatter plot demonstrated that there is a high correlation between b* jaundice, and a* redness. The results showed that cultivars and more landraces have general adaptability for all quality parameters, while some genotypes (G79, G78), (G22, G102), (G3) and (G121, G5) showed specific adaptation for N (nitrogen), PC (protein content) and L*, a* and b* values, respectively. According to the biplot techniques, G36 came forward with the N, P and a* value and desirable landraces, G5 for b* value, G30 stable line for all quality parameters, while (G128, G61) and the majority of promising lines (L4, L6) did not come forward with any quality parameters. The results of the study indicated that the majority of landraces can be used as parents to improve the quality of durum wheat varieties. The study indicated that GT biplot can be used to evaluate the genotypes graphically to select the best genotypes for parents to use in breeding programs.
Nutrient Status and Yield of Chickpea (Cicer Arietinum L.) as Influence by Application of Different Harvest Timing and Sulphur Fertiliser
(Scibulcom Ltd., 2015) Dogan, Y.; Togay, N.; Togay, Y.; Doğan, Yusuf
The objectives of this research were to study the effect of harvesting time and sulphur levels on the yield, protein and mineral nutritional value of chickpea seeds. Three different harvesting times (early, on-time and late) and four sulphur levels (0, 20, 40 and 60 kg ha–1) were used. Yield, protein ratio and mineral nutritional value of chickpea were significantly affected by sulphur and harvest timing. The highest grain yields according to the harvest time were obtained from on-time harvest with 1527 and 1434 kg ha–1 for the first and second years, respectively. The lowest grain yields were obtained from the control plots, whereas the highest values were obtained from the plots given 60 kg ha–1 sulphur. Generally, protein, phosphorus, calcium, magnesium, copper, zinc, and manganese concentrations of the seeds in on-time harvest and 60 kg ha–1 sulphur aplication were found to be greater than in early and late harvested plants. Positive significant relationships were found between harvest time and protein (r = 0.64**), Fe (r = 0.75**) and Zn (r = 0.27*). Positive significant relationships were found between sulphur doses and grain yield (r = 0.44*), protein (r = 0.26*), P (r = 0.71**), K (r = 0.73**), Ca (r = 0.36**), Mg (r = 0.76*), Zn (r = 0.57) and S (r = 0.96*). © 2015, Scibulcom Ltd.

Seed Priming With Zinc Oxide Nanoparticles And/Or Calcium Ion: Alleviation Potential for Salt Toxicity in Tomato (Solanum Lycopersicum) Through Modulation of Physiochemical Attributes and Antioxidant Enzyme Activity
(Pleiades Publishing, 2024) Dogan, Y.; Faisal, M.; Faizan, M.; Alatar, A.A.
Abstract: This study assesses how zinc oxide nanoparticles (ZnO-NPs) and calcium chloride (CaCl2), affect the physiology and growth of tomato (Solanum lycopersicum L.) under salt (NaCl) stress. Before sowing, tomato seeds were soaked in 100 mM of ZnO-NPs and 2 mM of CaCl2 for 12 h alone and in combination with 100 mM of NaCl. The findings showed that salinity stress had an adverse effect on tomato plant growth and physiology by reducing photosynthesis, fresh and dry weight, and the SPAD value of chlorophyll, carbonic anhydrase (CA), nitrate reductase (NR) while increasing the activity of antioxidant enzymes, hydrogen peroxide (H2O2), malondialdehyde (MDA), proline, and other chemicals that are directly linked to increased oxidative stress. Pre-treatment of ZnO-NPs and CaCl2 alleviated the negative effects of salinity on tomato plants, as indicated by improving these attributes. Seed soaking treatments of ZnO-NPs and CaCl2 was found efficient in improving the length, fresh and dry weight, photosynthesis, transpiration rate, total carbohydrate and reducing sugar in tomato plants under salinity stress. Beside, ZnO-NPs and CaCl2 decreased the NaCl-induced oxidative stress by declining proline, Na+, and Na+/K+ contents. Thus, our research showed that ZnO-NPs are more efficient and advantageous than CaCl2 in encouraging tomato plant growth and mitigating the negative impacts of NaCl stress. © Pleiades Publishing, Ltd. 2024.
