Publication Forage and grain yield performances of soybean lines(Univ Zagreb, Fac Agriculture, 2005-01-01) Bilgili, Uğur; BİLGİLİ, UĞUR; Şincik, Mehmet; SİNCİK, MEHMET; Göksoy, Abdurrahim Tanju; GÖKSOY, ABDURRAHİM TANJU; Turan, Zeki Metin; Açıkgöz, Esvet; Ziraat Fakültesi; 0000-0002-0012-4412; AAG-9296-2021; AAH-1539-2021; AAH-1811-2021Field experiments were conducted to evaluate the yield and yield components of twelve soybean genotypes as a forage and a grain crop in Marmara Region of Turkey in 2003-2004 growing seasons. Forage and dry matter yield and yield components at one vegetative stage (V5) and two reproductive stages (R2, and R4) and seed yield was determined in all soybean genotypes. The experiments showed that the harvest stages had significant effects on forage and dry matter yield, and R4 reproductive stage had the highest forage and dry matter yield. Dry matter partitioning of soybean plant parts was greatly affected by harvest stages, while the genotypes had little effect on dry matter partitioning of soybean plant parts. There were statistically significant differences between soybean genotypes in seed yield, but the differences were small. The correlations between forage and dry matter yield and seed yield were not statistically significant.Publication Determination of diurnal leaf gas exchange for drip-irrigated kenaf plant in sub-humid climatic conditions(Hard, 2022-01-01) Candoğan, Burak Nazmi; Yetik, Ali Kaan; Sincik, Mehmet; Demir, Ali Osman; Büyükcangaz, Hakan; CANDOĞAN, BURAK NAZMİ; SİNCİK, MEHMET; DEMİR, ALİ OSMAN; BÜYÜKCANGAZ, HAKAN; Ziraat Fakültesi; Tarla Bitkileri Bölümü; AAH-1811-2021; AAH-3102-2021; JLX-2232-2023; HHX-4880-2022Kenaf stands out as an important fiber source in the industry with its 4000-year history. Physiological properties have a great effect on the development process of kenaf. Physiological properties are significantly affected by seasonal air temperature changes and precipitation, as well as fluctuations during the day. The main reason for these fluctuations is seen as instant changes in environmental factors. In this study, it was aimed to determine the hourly changes of leaf gas exchange parameters of drip-irrigated kenaf plant and to examine the relationships between these parameters. Field experiment was conducted in Bursa, Turkey, which has sub-humid climatic conditions. For this purpose, net photosynthesis rate (A), stomatal conductivity (gs), intercellular CO2 concentration (Ci) and transpiration rate ( E) measurements were carried out on 18th September 2019 and 26th September 2020, between 08:00 h and 18:00 h. As a result of the study, while it was determined that A, gs, Ci and E parameters varied between 14.75-23.67 mu mol CO2 m(-2) s(-1), 0.23- 0.74 mol H (2) O m(-2) s(-1), 243-331 mu mol CO2 mol air(-1) and 2.67-7.37 mmol H (2) O m(-2) s(-1), respectively in 2019, they varied between 13.97-22.30 mu mol CO2 m(-2) s(-1), 0.29-0.58 mol H2O m(-2) s(-1), 217-278 mu mol CO2 mol air(-1) and 6.3-14.7 mmol H2O m(-2) s(-1), respectively in 2020. Different measurement times had significant effects on all parameters at the p<0.01 level for both years. As a result of the evaluation of the relationships between gas exchange parameters, it was determined that the gs-A and E-A relationships were statistically significant at the p<0.01 level for both years. On the other hand, in 2019 and 2020, Ci-A relationships were significant at p<0.05 and p< 0.01 probability levels, respectively. Information on the responses of leaf gas exchange parameters to weather changes occurring during the day in kenaf plant in sub-humid climate conditionsPublication GGE biplot analysis of genotype x environment interaction in soybean grown as a second crop(Soc Field Crop Sci, 2019-01-01) Kocatürk, Mehmet; Çubukçu, Pınar; Göksoy, Abdurrahim Tanju; Sıncık, Mehmet; İlker, Emre; Kadiroğlu, Abdullah; Vurarak, Yasemin; Şahin, Yeşim; Karakuş, Mehmet; Yıldırım, Ümran Akgün; GÖKSOY, ABDURRAHİM TANJU; SİNCİK, MEHMET; Ziraat Fakültesi; Tarla Bitkileri Bölümü; 0000-0002-0012-4412; 0000-0002-1568-2564; AAG-9296-2021; AAH-1811-2021The study was aimed to evaluate the adaptability and stability of the soybean genotypes based on the seed yield and the other observed characteristics in the sites cultivated second crop soybean of Turkey which have Mediterranean climate conditions using the GGE biplot analysis method. The experiments were performed under irrigated conditions in 2014, 2015 and 2016 in four different locations (Adana, Antalya, Izmir and Sanliurfa) of Turkey. Fourteen soybean genotypes consisting of 10 advanced soybean lines and four standard varieties were analyzed by a randomized complete block design with 4 replications. The combined analysis of variance revealed significant (P<0.01) effects for all sources of variation (environment, genotype, and GxE interaction) for the seed yield and yield components. Genotype and environment accounted for about 2.59% and 51.04% of the total variation for seed yield, respectively, while the GE interaction explained 20.84% of the total variation. According to the GGE principle, five mega-environments were formed in the present study. Results of the research revealed that genotypes G8 (KANA), G9 (KASM 02), G11 (ARISOY), G3 (BATEM 306), G1 (BATEM 207) and G12 (ATAEM 7) were found as stable. According to GGE Biplot analysis for all traits and genotypes, G4 (BATEM 317) had the largest values for plant height, first pod height, days to 50% flowering, days to maturity and seed yield.Publication Response and yield stability of canola (brassica napus l.) genotypes to multi-environments using gge biplot analysis(Univ Centroccidential Lisandro Alvarado, 2021-01-01) Acar, Mustafa; Gizlenci, Sahin; Atagun, Gulhan; Suzer, Sami; Ulusoy, Yahya; ULUSOY, YAHYA; Sincik, Mehmet; SİNCİK, MEHMET; Senyigit, Emre; ŞENYİĞİT, EMRE; Goksoy, Abdurrahim T.; GÖKSOY, ABDURRAHİM TANJU; Mustafakemal Paşa Yüksekokulu; Tarla Bitkileri Ana Bilim Dalı; 0000-0002-0012-4412; 0000-0001-8641-6995; 0000-0003-2658-3905; AAH-1811-2021The GxE interaction (GEI) provides essential information for selecting and recommending cultivars in multi-environment trials. This study aimed to evaluate genotype (G) and environment (E) main effects and GxE interaction of 15 canola genotypes (10 canola lines and 5 check varieties) over 8 environments and to examine the existence of different mega environments. Canola yield performances were evaluated during 2015/16 and 2016/17 production season in three different locations (Southern Marmara, Thrace side of Marmara, and Black Sea regions) of Turkey. The trial in each location was arranged in a randomized complete block design with four replications. The seed yield data were analyzed using GGE biplot and the yield components data were analyzed using ANOVA. The agronomical traits revealed that environments, genotypes, and GEI were significant at 1 % probability for all of the characters. The variance analysis exhibited that genotypes, environments, and GEI explained 21.6, 21.7, and 25.7 % of the total sum of squares for seed yield, respectively. The GGE biplot analysis showed that the first and second principal components explained 57.3 and 18.3 % of the total variation in the data matrix, respectively. GGE biplot analysis showed that the polygon view of a biplot is an excellent way to visualize the interactions between genotypes and environments.Publication Effect of rainfed and irrigated conditions on yield and quality traits of new-improved sunflower (Helianthus annuus) hybrids in a sub-humid climate(Indian Council of Agricultural Research, 2013-01-01) Öz, Mehmet; Karasu, Abdullah; Kuşcu, Hayrettin; Sincik, Mehmet; Turan, Z.

Over two years (2006 and 2007), significant differences for all characters except plant height and crude oil per-cent were found between irrigation regimes (irrigated and non-irrigated conditions) while genotypes showed significant differences for all characters investigated. Also, genotype x irrigation regime interaction was highly significant for all traits except crude oil percent. In addition, year x irrigation regime, year x genotype and year x genotype x irrigation regime interactions were statistically significant for head diameter, 1 000 seed weight, seed yield and crude oil yield. The seed yield and crude oil yield increased highly with irrigations. The seed yield increases for irrigated treatment compared with non-irrigated treatment were 58.3 % in 2006 and 101.4 % in 2007. Compared with non-irrigated treatment, crude oil yield increases for irrigated treatments were 56.9 % in 2006 and 99.4 % in 2007. Differences between genotypes in seed yield and crude oil yield significantly varied according to irrigated and non-irrigated conditions. The control variety, Sanay and experimental hybrid, C 10 x R 10 produced more seed yield and crude oil yield than those of others in irrigated conditions, whereas highest seed yield and crude oil yield was obtained from the control variety, Muson in non-irrigated condition and differences among other hybrids were not statistically significant under rainfed condition.
