Mustafa Güneşdoğdu | Ahmet Şekeroğlu
The basic rule in honeybee (Apis mellifera L.) rearing is to work with qualified queens. Quality queen means strong and healthy colonies. Honey bee colonies are a social community, each managed by a single queen bee. The queen bee is the only female that produces eggs in the colony under normal conditions, and the quality and healthy queen is important for the continuity of the colony. Many factors affect the quality of the queen bee, such as the rearing colony, the age of the transferred larva and the transfer medium, the season, cell emergence weight, spermatheca charged, the characteristics of the starter and finisher hives. In this paper, the issues to be considered in raising a quality queen are emphasized.

It is known that agricultural lands remain limited due to the ever increasing human population. That is why the necessity of increasing the crop production is constantly emphasized. In the crop production, quality should be increased along with yield. Nonetheless, there are amounts that people should take from each group of nutrients daily to ensure adequate and balanced nutrition. As known, malnutrition has negative effects on human health, which causes some diseases. Field crops, as well as other feeding groups, are of great importance in human nutrition. It is known that oil plants, which belong to the group of industrial plants, have an important place in human nutrition as in the vast majority of field crops. Thus, in this article, some important oil plants will be examined in terms of human nutrition.

Yield and quality performances of 27 soybean cultivars were evaluated in two years field experiment between 2015 and 2016 at the Experimental Farm of Faculty of Agricultural Sciences and Technologies, Nigde Omer Halisdemir University, Nigde, located in the Central Anatolia Region. The field experiments were laid out in the randomized complete block design with three replications in each year. The main phenological stages of development such as time to emergence, flowering, time to pod formation and time to maturity were determined as calendar days. Plant height, the first pod height, numbers of branch, pod and seed per plant, number of seed per pod, 100-seed weight, protein content, oil content and seed yield per decar were determined as yield and quality parameters. The results of two-year study revealed that the soybean cultivars differed significantly for all characters studied under Nigde conditions. It was also observed that yield and quality performances of cultivars fluctuated in years. Average seed yield values of cultivars were ranged from 135.2 kg/da-1 (Inton-I. maturity group) to 295.8 kg/da-1 (Adasoy-IV maturity group) in 2015 and 2016. In two years mean, the cultivars Adasoy, Sa-88 and Nova were determined as the most promising genotypes for main crop production in Nigde conditions.

Ayşe Bayramoğlu | Fatih Şen
This study was carried out to determine the effects of different openings onto the polyethylene (PE) packages used in storage of ‘Sultani Çekirdeksiz’ grape variety on quality, SO2 damage, pathological and physiological disorders of grapes. Grapes were harvested at full maturity and placed in PE bags with ‰0 (control), ‰0.5, ‰1 and ‰2 openings. After pre-cooling grapes in the case of SO2 pets were placed after the mouth of the bags were closed. Grapes were stored at 0°C and 90-95% relative humidity for 4 months, and quality changes were determined in monthly samples. SO2 concentrations detected at the end of storage in PE packages with ‰0, ‰0.5, ‰1 and ‰2 openings were 11.16, 5.80, 2.05 and 0,00 mg/kg respectively. It has been found that grapes in packages without opening had significant SO2 content and SO2 damage, especially the end of storage. However, grapes in packages with ‰2 openings had high weight loss and browning scores in stems. The results showed that ‘Sultani Çekirdeksiz’ grapes could be stored more successfully in PE packages with ‰0.5 openings. ‘Sultani Seedless’ grape variety, it may be suggested to use PE bags without openings for 2 and 3 months storage.
