This study was carried out to determine the effects of increasing cadmium (Cd) doses (0, 10 and 25 mg kg-1 soil) on root and shoot dry weights, shoot Cd, macro-and micronutrient compositions of bread (Seri-82) and durum (Balcali-85) wheat genotypes. Plants were grown under controlled conditions for 47 days. Following the harvest, shoot and root dry matter productions were determined, and the concentrations of nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), iron (Fe), copper (Cu), zinc (Zn), manganese (Mn), and Cd in shoots were measured. Macro-and micro-nutrient contents were calculated by multiplying shoot dry weights and nutrient concentrations. Increased Cd doses significantly decreased (P< 0.05) root and shoot dry matter productions and most of nutrient contents in shoot. The declines in shoot and root dry weights with increasing Cd levels were higher in durum wheat than bread wheat. Durum wheat genotype had higher Cd concentration in shoot than that of bread wheat. Effects of cadmium treatments on variations of nutrient contents were found to be different. Cadmium supplies decreased N, P, K, Fe, Zn and Cu contents of bread wheat and all measured element contents of durum wheat. The results revealed that durum wheat genotype was more sensitive to Cd supply than bread wheat and high Cd accumulation was possibly associated with more distinctive decreases of nutrient uptakes in durum wheat than bread wheat.

The present study was conducted to determine the effects of 3 different levels of probiotic on hatchability of Japanese quail (Coturnix coturnix japonica). In this study, 225 female Japanese quails were used. The experimental quails were divided into 3 dietary treatment groups of similar mean weight comprising 75 birds each, which was divided into 3 subgroups of 25 birds each. Treatment groups were assigned control group A (unsupplemented diet), group B (0.5 kg/tonne commercial probiotic supplemented diet) and group C (1.0 kg/tonne commercial probiotic supplemented diet) for 5 weeks. After 5 weeks, probiotic treatment was ceased and then all groups were allowed to nourish standard layer diet. Results showed that protexin supplementation to the diet did not affect hatchability of total eggs set, hatchability of fertile eggs set and fertile egg%.

A greenhouse pot-experiment was conducted in this research to investigate the effects of zinc (Zn) nutrition on sodium chloride (NaCl) stress of a bread wheat genotype (Triticum aestivum L., cv. Ceyhan 99). Plants were grown under 2 different Zn (0.25 and 5 mg kg-1 soil) and 3 different NaCl (0, 5 and 10 dS m-1) treatments. Plants were harvested after 78 days of growth and shoot dry matter production, shoot Zn, sodium (Na), potassium (K) and calcium (Ca) concentrations were determined and also shoot K/Na and Ca/Na ratios were calculated. Increasing salinity levels reduced shoot dry weights at both Zn doses. The reduction of dry weight in increased salinity with low Zn conditions receded remarkably with sufficient Zn treatment. Sufficient Zn application increased shoot Zn concentration significantly at all salt levels. Increases in Na concentration with salt treatments were found to be higher at low Zn supply than sufficient Zn conditions. Higher K concentrations were observed in each salt dose at sufficient Zn than low Zn level. Under high salt treatment, shoot K concentration significantly decreased at both Zn supplies. Calcium concentration of shoot significantly increased with increasing salinity doses at both Zn treatments. Lower Ca concentrations were observed at sufficient Zn than deficit Zn levels under 5 and 10 dS m-1 salinity levels. K/Na and Ca/Na ratios significantly decreased with increasing salinity under both Zn doses. The results showed that sufficient level of Zn in soil may ameliorate the detrimental effects of NaCl stress in bread wheat by reducing Na and increasing K concentrations in shoots. © by PSP.

This research was conducted to determine forage yield and botanical composition of duo (alfalfa + one grass) and trio ( alfalfa + two grasses) mixtures of some warm season perennial grass species such as dallis grass (Paspalum dilatatum Poir.), Rhodes grass (Chloris gayana L.), Bermuda grass (Cynodon dactylon (L.) Pers.) Guineae grass (Panicum maximum Jacq.), blue couch grass (Digitaria didactyla Willd) and finger grass (Digitaria milanjiana (Rendle) Stapf) with alfalfa (Medicago sativa L.) as well as their pure sowings under irrigated conditions of Mediterranean during the years of 2011 and 2012. In the study, green herbage yield, dry matter yield, alfalfa proportion in dry matter yields and land equivalent ratio (LER) were determined. The experimental design was completely randomized block design with three replications. According to the results, it was determined that the ratios of warm season grasses in the botanical composition of the mixtures declined with the establishment age while rate of alfalfa in the botanical composition of the mixtures increased. Increasing the rate of alfalfa in the botanical composition of the mixtures also increased hay quality of the mixtures. The mixtures gave higher dry matter yield than pure sowings of the species. The highest green herbage yield (98.14 t ha1) was obtained from the mixture of Rhodes grass + alfalfa. The highest dry matter yield (22.46 t ha1) was obtained from the mixture of dallis grass + Guinea grass + alfalfa. The highest value of land equivalent ratio (LER) (1.49) was obtained from the mixture of bermuda grass +Rhodes grass + alfalfa. From the results of the study, it was concluded that Guinea grass and finger grass did not show good adaptaion to the Cukurova conditions due to low temperatures during the winter season. Bermuda grass, Rhodes grass, blue couch grass and dallis grass could be used to establish pasture mixtures with alfalfa, having long grazing season and giving high hay yield and quality. Before the establishment of such pasture mixtures, it was needed to research proper mixture ratios and proper management techniques of the mixtures. © 2014, Society of Field Crops Science.

This study was carried out to determine the effects of cadmium (Cd) (0 and 2 mg kg-1 soil) and salt stress (NaCl 0 and 3000 mg kg-1 soil) on shoot dry weights and shoot Cd, sodium (Na) and potassium (K) concentrations of salt-tolerant (Maverik) and salt-sensitive (RX-9292) hybrid maize varieties. Plants were grown under controlled greenhouse conditions for 19 days. Shoot dry matter productions and shoot Cd, Na and K concentrations were determined following the harvest. Element contents were calculated by multiplying shoot dry weights with element concentrations. Cadmium, NaCl and Cd+NaCl treatments significantly decreased (P < 0.05) shoot dry matter productions of both varieties. The decline in dry matter production was higher in RX-9292 compared to Maverik. Higher increases in Cd concentrations and contents with Cd treatments were observed in RX-9292 than that of Maverik. Combined treatments of Cd and NaCl also yielded higher Cd concentration and contents in RX-9292 compared with Maverik. The variety of RX-9292 had higher Na concentration and content than Maverik under NaCl and Cd+NaCl treatments. Cd-induced growth decline and Cd accumulations in shoots revealed that salt-sensitive RX-9292 was more sensitive to Cd compared to the salt-tolerant Maverik. Plant tolerance of Cd and salinity should definitely be known in cultural practices carried out over agricultural lands with salinity and Cd concerns.

This study aimed to evaluate the effects of probiotics on fattening performance and carcass parameters in 1-to 35-day-old Japanese quails. Day-old male Japanese quail chicks (288) were randomly divided into 4 treatments with 3 replicates of 24/pen (mean body weight 8.39 g). The dietary treatments were as follows: Group A, basal diet; group B, basal diet supplemented with 0.5 kg/tonne protexin; group C, basal diet supplemented with 1.0 kg/tonne protexin; and group D, basal diet supplemented with 1.5 kg/tonne protexin. The study lasted for 5 weeks. Results showed that probiotic did not influence body weight gain (BWG), feed intake (FI), feed conversion ratio (FCR), and carcass traits of 35-d-old broilers (P> 0.05). Inclusion of 1.5 kg/tonne probiotic in the diet of quails decreased average weekly body weights, compared with those fed with basal diet and another groups (P< 0.05).

This study was conducted to determine the effect of water stress to maize during 3 different growing periods on field at the Agricultural Research Institute during 2008 - 2009. In this study, the material for seed was P-3394 hybrid maize and 4 water stress treatments were examined in different growing periods. Plant height, ear height, thousand grain weight, ear diameter, ear size, grain number per ear and some agronomic characteristics were determined. Seasonal evapotranspiration was 771.2 mm. Monthly evapotranspiration varied from 90 to 195 mm/month (3 - 6.5 mm/day). According to those findings, the plants must be irrigated 5 times including emergency water at different periods, especially in the periods of tassel irrigation had to be made on time without skip. Application of water shortage to field is reduced 9% in the period of pollination (corn tassel). It was predicted that the first irrigation for second crop maize in Çukurova had to apply 30 - 35 days later from sowing, second irrigation before corn tasseling, third irrigation during the emergence period of ear, and fourth irrigation in the period of grain loading, totally 5 irrigation applications, including tail-water.
