In this study carried out in 2015 under conditions of Kahramanmaraş province of Turkey, it was aimed at determining the effects of sawgin and rollergin methods on fiber quality in some cotton (Gossypium hirsutum L.) cultivars. In the study varieties of Lydia, Carisma, PG 2018, Flash, BA 440, BA 119 Maraş-92 and Erşan-92 were used as experimental materials. The trial was established according to factorial randomized block design with four replications. Seed cottons obtained from the trial were ginned in the rollergin and sawgin machines. In the obtained lint cotton samples, a number of fiber characteristics were determined by using HVI and AFIS fiber analysis devices. Ginnig outturn (38.6%), fiber length (30.21 mm), uniformity index (86.02%), fiber strength (31.76 g tex-1), spinning consistency index (SCI) (104.68) determined by using rollergin system were found higher than ones determined by using sawgin system (respectivelly 37.2%, 29.78 mm, 84.61%, 30.97 g tex-1, 94.50). Short fiber index (3.47%) and nep count (59.40 number g-1) obtained from rollergin system were found lower than ones obtained from sawgin system (respectivelly 4.38% and 119.34 number g-1). As a result it can be said that the rollergin method has positive effect on ginnig outturn, fiber length, uniformity index, fiber strength, spinning consistency index, short fiber index and nep count. When fiber length, fiber strength, spinning consistency index, nep size are considered together the best variety was Lydia cv. (respectivelly 30.87 mm, 32.56 g tex-1, 104.25, 675.63 μm). Ginning outturn, uniformity index, short fiber index, total particule number, dust particule number and trash count are considered together the best variety was Erşan-92 cv. (respectivelly 39.4%, 86.02%, 3.48%, 231.4 number g-1, 206.3 number g-1, 25.13 number g-1). For fiber fineness the best varieties were BA 119 and Maraş-92 cv. (respectivelly 4.78 mic. and 4.80 mic.).
This study was performed in the 2013-2014 cultivation season with the purpose of determining the most suitable planting season of fenugreek under the ecological conditions of Kahramanmaraş. The trial was established in two different cultivation periods as winter and spring at the Eastern Mediterranean Transition Zone Agricultural Research Station in according to factorial randomized block design with three replications. In the study, the Gürarslan fenugreek variety as well as Candicate Line-1 and Genotype-1 fenugreek genotypes were used as material. In the study, features such as plant height, first pod height, number of branches per plant, pod length, number of pods per plant, number of seeds per pod, seed yield per plant, seed yield per decare, thousand seed weight, mucilage rate, fixed oil ratio, fixed oil yield, crude protein ratio, humidity, raw ash ratio, and the rates of linoleic acid, alpha linoleic acid, oleic acid, palmitic acid, stearic acid as important fatty acids were studied. Variance analysis made on the data obtained by using SPSS statistical package program. In the comparison of the means, Duncan multiple comparison test was used. As a result, in this study, was found that in the region where the study was performed, the most suitable planting season for fenugreek cultivators is the winter planting dated winter planting when the highest values of plant height, number of pods per plant, seed yield per plant were obtained. From the features studied in the research the difference between genotypes was found significant only from the perspective of seed yield per plant and fixed oil ratio. While the best results were obtained from Genotype-1 for seed yield per plant, the best results for fixed oil yield were obtained from Candicate Line-1.
