Tan, Mustafa; Yolcu, Halil; Dumlu Gul, Zeynep
Sunflower (Helianthus annuus L.) having shorter growing season, better cold tolerant and more drought resistant is important alternative silage plant in highlands. But it has poor silage quality. To improve the quality of sunflower silage can be mixed an appropriate amount of corn (Zea mays L.) and alfalfa (Medicago sativa L.). This research was carried out to evaluate quality characteristics of nine silage types: Sunflower, corn and alfalfa silages; plus their some mixtures silages (75% sunflower + 25% corn, 50% sunflower + 50% corn, 25% sunflower + 75% corn, 75% sunflower + 25% alfalfa, 50% sunflower + 50% alfalfa and 25% sunflower + 75% alfalfa); at two harvest stages: Beginning of flowering for sunflower and alfalfa and milk-dough stage for corn (early stage), and end of flowering stage for sunflower and alfalfa, and dough stage for corn (late stage). The experimental design was in a factorial arrangement of randomized complete block with replicated four times. Dry matter content (DM), crude protein content (CP), neutral detergent fiber content (NDF), acid detergent fiber content (ADF), silage pH and physical characteristics (PC) of silages were determined in this study. Mixing of alfalfa in NDF, ADF and CP and corn in DM, pH and PC had positively effect in sunflower silages. Late stage had positively affected DM, PC and pH for silage. Consequently, sunflower silages mixed with corn, with the condition of not being less than 50% at late stage, are recommended for farmers.

Yildirim, Mustafa; Çakmak, Mustafa
Grain yield estimate from early segregating populations is an interesting feature of today's wheat breeding programs, and F-1 populations are generally recommended as the most suitable population by researchers. In the present study, we evaluated the population vigor of diallel F-4 offsprings of six bread wheat genotypes (Sultan, Bezostaya, Suzen, Harmankaya, Altay and Gerek) under irrigated (IR) and rain-fed conditions (RF). The experiment as two sets under IR and RF were established in the field of Anatolian Agricultural Research Institute, Eskisehir. The mean of grain yield (5468 kg ha(-1)) of F-4 populations in RF and IR had been lower than the mean of genotypes (5654 kg ha(-1)). The mean of grain yield of genotypes (7062 kg ha(-1)) under IR was higher than F-4 populations (6703 kg ha(-1)), while genotypes and F-4 populations were nearly similar under RF (4246 kg ha(-1) and 4234 kg ha(-1), respectively). The mid-variety population vigor for grain yield varied from -6.70% (Hrm/Grk) to 8.77% (Bez/Grk) under RF, and from -22.58% (Sltn/Alty) to 10.87% (Bez/Suzen) under IR. There was not positive significance population vigor in F(4)s. According to results under RF and IR, F-4 populations are observed as the most suitable populations for realistically estimation of grain yield performance of populations.
