This research was carried out to compare the yield and quality characteristics of four sunflower (Helianthus annuus L.) genotypes (i.e., confectionery Tekirdag landrace, confectionery Erzurum landrace, oilseed Sirena and oilseed C70165 hybrids) and one corn (Zea mays L.) genotype (i.e., SZE TC-S13 hybrid) in the Agriculture Faculty of Ataturk University in the east of Turkey during the period between 2005 and 2006. The study was designed in a randomized complete block design with five treatments replicated three times. The genotypes were evaluated in terms of forage properties as well as chemical and physical properties of silages in both years. According to the results, the corn genotype had better yield and silage qualities than sunflower genotypes. But crude protein contents of silages of sunflower genotypes were superior in comparison to the corn genotype. Also amongst sunflower genotypes, confectionery Tekirdag and Erzurum landraces had slightly higher silage qualities than oilseed sunflower hybrids. Source

Sugar beet is one of the most important crop among the other major industrial crops. Plants are used directly or indirectly in many areas. The suitable agro-ecological growing areas for sugar beet should be determined. Crop growth planning should be done according to agro-ecological zones. The use of water resources in accordance with plant needs in the most effective way is of great importance. Water consumption of the sugar beet should be calculated according to the development period and location where the crop is grown. In this study, the calculation of the reference water needs of the sugar beet plant according to different climate conditions of Turkey was performed. Thus, by knowing the water needs and irrigation water consumption of the sugar beet, current water resources could be managed effectively. © 2015 IEEE. Source

The aims of the study were to determine heritabilities of growth characteristics and growth characteristics of Morkaraman sheep raised by local breeders in Erzurum province between 2006 and 2010. Growth characteristics such as live weight and daily live weight gains of Morkaraman lambs in the various periods were examined for this purpose. The effects of some environmental factors such as herd type, sex, birth type and years on these characteristics were also examined. In the study, growth characteristics of lambs obtained from mating of 5339 ewes and 253 rams were measured based on performance tests and a selection practice was performed. Elite, multiplier flock and commercial herds were established. The heritabilities of traits in question were determined. The breeding value for daily live weight gains up to the end of grazing season in the fifth year was calculated. Birth weight, birth weight heritability, weights and weight heritability at the beginning of grazing season, weight and weight heritability at the end of grazing season, daily live weight gain up and daily live weight gain heritability to the beginning of grazing season, daily weight gain up and daily live weight gain heritability to the end of grazing season were found 3.5±0.01 kg, 0.26±0.149, 21.4±0.07 kg and 0.41±0.103, 37.4±0.09 kg and 0.43±0.138, 239±1.33 g and 0.48±0.083, 201±0.78 and 0.47±0.082, respectively. At the end of the research, to improve the growth characteristics of Morkaraman sheep and to increase live weight gain to be obtained from each lamb were targeted. As a result, the live weights at the end of grazing season of lambs, Morkaraman provided an increase of approximately 5 kg. In terms of examined growth characteristics of Morkaraman sheep measured by individual performance testing, it is determined that Morkaraman sheep can be breeded by local breeders to improve its growth traits. © 2013 © 2013 Taylor & Francis.
