Amino Acid Profile, Nutrients Content and Yield of Chickpea (Cicer Arietinum L.) Genotypes
(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.

Correlation and path coefficient analysis for yield and some yield components of wheat (Triticum aestivum l.)
(Scibulcom Ltd., 2017) Togay, Necat; Togay, Yeşim; Doğan, Yusuf; Doğan, Yusuf
The experiment was conducted to determine the relationship among yield and some yield components using correlation and path coefficient analysis. This study was performed under Mardin conditions the years of 2011–2012 and 2012–2013. Fifteen bread wheat varieties were used in the experiments. The randomised complete blocks design with 3 replications was used. The characteristics such as plant height, spike height, numbers of seed per spike, seed yield, harvest index, biological yield and 1000 seed weight were investigated in the study. Positive and statistically significant (p < 0.01) relationships were determined between seed yield, spike height, numbers of seed per spike, biological yield and harvest index. According to path coefficient analysis, there were strong direct effects of the biological yield and harvest index on the seed yield, p = 0.53549 and 0.548321, respectively. The results of this study indicate that numbers of seed per spike, biological yield and harvest index affected seed yield and it was concluded that these characters should be considered as significant selection criteria in wheat breeding for yield under the regional conditions of southeast Turkey. © 2017, Scibulcom Ltd.

Effects of Zno Nanoparticules Produced by Green Synthesis on Germination and Seedling Of Salvia Officinalis L. Seeds
(Polish Society Magnesium Research, 2021) Gunes, Zubeyir; Toncer, Ozlem; Eren, Abdullah
Nanotechnology is a research subject in many interdisciplinary engineering fields today. Nanoparticles have important effects on seed germination and seedling growth of plants. The aim of this study has been to produce a 54.68 nm-sized ZnO nanoparticle obtained from the Nigella sativa L. plant by green synthesis. The effect of medicinal sage (Salvia officinalis L.) on germination of plant seeds and seedling growth was investigated. The trial was set up under controlled conditions and conducted for 14 days according to a factorial trial design with 5 replications for each dose (0, 0.5, 1.5 and 2.5 mg ZnO NP kg-1). As a result of ZnO NP application in different doses, germination of Salvia officinalis L. seeds varied between 90-94%, stem length was 1.86-2.92 cm and shoot length was between 1.01-1.98 cm. The highest root and shoot length was obtained after the application of 2.5 mg ZnO kg-1 NP. In the light of the results, ZnO nanoparticles are thought to be useful for seed development and agricultural applications.
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.
