(Academic Journals, 2008) Togay, Necat; Togay, Yesim; Dogan, Yusuf
Significant grain yield increase to applied municipal sewage sludge was obtained. This study was carried out in order to investigate the effects of the different doses municipal sewage sludge application on the heavy metal concentrations, yield and quality of dry bean in the 2006 and 2007 years. The trial was conducted in randomized complete block design with three replications. Four municipal sewage sludge doses (0, 20 000, 40 000 and 60 000 kg ha(-1)) were applied. Significantly higher pod and seed number per plant in municipal sewage sludge treatments had increasing effects on grain yield. Whereas grain yield, which was the highest component was obtained from 60 000 kg ha(-1) municipal sewage sludge with 1766.3 kg ha(-1) in the first year and with 1881.6 kg ha(-1) in the second year. The lowest grain yield were obtained from 0 kg ha(-1) municipal sewage sludge in both years. 60 000 kg ha(-1) municipal sewage sludge application was optimal with respect to increasing yield and yield characteristics. Concentrations of heavy metals in grain and shoot were similar to those in the fertilizer treatments. Cu, Zn, Cr, Pb and Ni in grain and shoot were well below their toxic thresholds.
Evolotion Barley Genotypes in Multi-Environment Trials by Ammi Model and Gge Biplot Analysis
(Parlar Scientific Publications (p S P), 2019) Oral, Erol; Kendal, Enver; Kilic, Hasan; Dogan, Yusuf
The uniformity of genotypes are significant for crop breeding program decisions to improve new varieties. The AMMI (Additive main effects and multiplicative interaction) analysis and Genotype x Environment Interaction (GEI) is make to estimation grain yield and understands GxE interaction patterns by researches as differential ranking of variety yields in multi-environment trials. Therefore, fifteen barley advanced line and six national cultivars and four foreign varieties (registered in abroad) were used in the study. The experiments were performed according to a complete randomized block design with four replications at five environments during two years. The stability and superiority of genotypes for yield and other traits were determined using AMMI and GGE biplot analysis. Factors (G, GE, and GEI) were found to be highly significant (P < 0.01) for grain yield. AMMI analysis indicated that the major contributions to treatment sum of squares were environments (98.52%), GE (0.45%) and genotypes (1.02%), respectively, suggesting that grain yield of genotypes were effected environmental conditions. The GGE biplot indicated that PCA 1 axes (Principal component) was significant as P<0.01 and supplied to 49.36% of complete GxE interaction. The AMMI indicated that G8 and G23 desirable and stabile genotypes for grain yield in multi-environment. Moreover, E2 and E5 (irrigated environments) were high yielding, while E3 (drought stress) low yielding as forecast. On the other hand, GGE biplot indicated that three group were occurred among traits, first group (GY: grain yield, CC: crude cellulose, CD: cold damage), second group (PC:, HVV: hectoliter weight, TGW: thousand grain weight, SH: seed humidity), third group (LOD: lodging, PH: plant height, HT: heading time). Moreover: the study showed that G3, G6, G7, G8, G13 and G21 were the best genotypes both grain yield and other traits. The results of AMMI model and GGE biplot indicated that G8 is suitable to recommend for release and G23 desirable origin for yield stability and G7 valuable source for quality to use in barley breeding program.
Relationships Between Yield and Some Yield Components in Pea (Pisum Sativum Ssp Arvense L.) Genotypes by Using Correlation and Path Analysis
(Academic Journals, 2008) Togay, Necat; Togay, Yesim; Yildirim, Bunyamin; Dogan, Yusuf
This research was carried out Yuzuncu Yil University, Agricultural Faculty experimental field in 2002-03 and 2003-04. The experiment was conducted to determine the relationship among yield and some yield components using correlation and path coefficient analysis. In the experiment 12 pea genotypes were used. The experiment was designed randomized complete blocks design with four replications. At the end of the study, positive and significant relationship were found among seed yield and pods per plant and biological yield in both years. The strongest and direct positive effects were the biological yield (p = 0.6500), numbers of pods per plant (p = 0.3137) and the seed yield. These were followed by first pod height (p = 0.2398) and number of seeds per pod (p = 0.2227).
Research on the Effect of Phosphorus and Molybdenum Applications on the Yield and Yield Parameters in Lentil (Lens Culinaris Medic.)
(Academic Journals, 2008) Togay, Yesim; Togay, Necat; Dogan, Yusuf
Lentil is one of the oldest domesticated crops grown and used mostly in human diets in Turkey. The trial was laid out in a factorial randomized complete block design with three replications. Sazak-91 lentil variety was applied at three different phosphorus levels ( 0, 30 and 60 kg ha(-1)) and four different molybdenum levels ( 0, 2, 4 and 6 g/kg seed) in 2005-2006 and 2006-2007. In the study, the effect of phosphorus and molybdenum levels on the plant height, number of branches, number of pods per plant, number of seeds per plant, 1000 seed weight, grain yield, harvest index, biological yield, number of nodules per plant, root dry weight, shoot dry weight protein ratio and phosphorus content in seed were investigated. Whereas the highest grain yield were obtained from 60 kg ha(-1) P with 1086 kg ha(-1) and from 6 g/kg seed molybdenum with 1231 kg ha(-1) in the first year, the values were 80 kg ha(-1) P with 1049 kg ha(-1) and from 6 g/kg seed molybdenum with 1089 kg ha(-1) in the second year.
Variation of Salinity Tolerance in Bean Genotypes
(Academic Journals, 2011) Ciftci, Vahdettin; Turkmen, Onder; Dogan, Yusuf; Erdinc, Ceknas; Sensoy, Suat
Bean is among the very sensitive plant species to soil salinity. This study was carried out using the 55 bean genotypes collected from Gevas-Van region in Turkey to determine their salinity tolerance. This study aimed to investigate the salt tolerance capacity of this local bean population. 50 mM NaCl was applied to the bean seedlings, and the measurements and observations were done 20 days after the salt application, when the differences among the genotypes appeared. Number of leaves, seedling heights, and root and shoot weights and some nutrients (phosphorous, potassium, iron, calcium, manganese, magnesium, copper, zinc, and sodium) of the seedlings were determined. The wide variation at salt stress tolerance was observed in this population. The overall performances of local genotypes were better than the tried commercial cultivars.
