Determination of Physiological and Biochemical Reactions of Different Pea Varieties and Lines Under Chilling Stress
(Scibulcom Ltd, 2016) Togay, Y.; Yasar, F.; Togay, N.; Yildirim, B.; Uzal, O.
Under field conditions, growth parametres like fresh weight and leaf number, superoxide dismutase (SOD), catalase (CAT), ascorbic peroxidase (APX) enzymes in the antioxidant defence sytems are analysed on 12 lines and two cultivars of pea seedlings which are specified as tolerant against cold. Besides the relationship between the protection mechanisms from abiotic stress conditions (change on the antioxidant enzymes) on the pea plant is tried to be revealed. In terms of macro and microelement accumulation, considering control plants, the effect of low temperature application is not observed in Mn, Mg, Cu microelements. However, approximately ten times decrease is observed on Fe and Zn accumulations. It is also observed that there is not a change on K and Ca accumulation of the plants considering control plants. It is seen that with the low temperature application, there are significant increases on CAT, APX and SOD enzyme activities which are among the antioxidant enzymes of the plants.
Effect of Different Sowing Time on Yield and Yield Components of Lentil (Lens Culinaris Medic.) Varieties in Mardin Kiziltepe Conditions
(Univ Namik Kemal, 2014) Dogan, Y.; Togay, Y.; Togay, N.
The aim of this work is to determine the most suitable sowing date for lentil in Mardin Kiziltepe conditions. Three cultivars of lentil (Firat-87, Sakar andYerli Kirmizi) were sown at three different sowing dates (November 10, 25 and 10 December). The trial was conducted in the experimental fields of Kiziltepe Vocational High School of Mardin Artuklu University by using split plots in randomized factorial blocks design with the three replicates in years of 2011-12 and 2012-13. Experiment was established as main plots and sowing times treatments as split plots. Effects of sowing dates on plant height, first pod height, numbers of pod per plant and numbers of seed per plant, numbers of seed per pod, 1000 grain weight, grain yield, harvest index and biological yield were investigated for three cultivars. According to the two years results; effects of varieties and sowing time on the yield and yield components of lentil were obtained significantly. While the highest grain yield per area was obtained at the Sakar cultivar as 237.48kg/da and 210.34 kg/da, the lowest grain yield per area was obtained at the Yerli Kirmizi cultivar as 164.07 kg/da and 148.22 kg/da in years of 2011-12 and 2012-13 respectively. The most suitable sowing time was determined with November 25 in Mardin conditions.

(Agricultural Research Communication Centre, 2015) Togay, N.; Togay, Y.; Erman, M.; Cig, F.
The study was carried out to determine the effect of different levels of iron (0, 5, 10 and 20 kg ha(-1)) and molybdenum (0, 2, 4 and 6 g kg(-1) seed) on the yield and yield components in lentil (Lens culinaris Medic. cv. Sazak-91). The experiments were conducted in a factorial design with three replications during 2006-07 and 2008-09 in Van, Turkey. The highest seed yield was obtained from 20 kg ha(-1) iron with 956 kg ha(-1) and 6 g kg(-1) seed molybdenum levels with 963 kg he in the first year, while it was obtained from 20 kg ha(-1) iron with 1031 kg ha(-1) and 6 g kg(-1) seed molybdenum with 1010 kg ha(-1) in the second year. Seed nutrient contents such as protein rate, phosphorus, manganese, copper and molybdenum significantly increased under the influence of iron and molybdenum treatments over control.
Effect of Humic Acid and Phosphorus Applications on the Yield and Yield Components in Lentil (Lens Culinaris Medic.)
(Agricultural Research Communication Centre, 2014) Dogan, Y.; Togay, Y.; Togay, N.; Kulaz, H.
Lentil is commonly grown as a rotation crop in east and southeast of Turkey. It is an important crop because of its high protein content of seed and straw for human and animal nutrition. Phosphorus in the soil has developmental activity in the plant's root growth. The effects of humic substances on plant growth, under conditions of adequate mineral nutrition, consistently show positive effects on plant biomass. An experiment was conducted to study the effect of different levels of humic acid and phosphorous on yield and yield attributes of lentil during 2008-09 and 2009-10 in Agricultural Faculty experiment field of Yuzuncu Yil University. The results of the study indicated that humic acid and phosphorus applications increased significantly the seed yield and yield components. Whereas the highest seed yield were obtained from 80 kg phosphorus ha(-1) with 1135 kg ha(-1) and 600 kg humic acid ha(-1) application with 1097 kg ha(-1) in the first year, the values were 80 kg phosphorus ha(-1) with 1756 kg ha(-l)and 600 kg humic acid ha ha(-1) application with 1625 kg ha(-1) in the second year.

Effects of Rhizobium Inoculation, Sulfur and Phosphorus Applications on Yield, Yield Components and Nutrient Uptakes in Chickpea (Cicer Arietinum L.)
(2008) Togay, N.; Togay, Y.; Cimrin, K.M.; Turan, M.
This study was carried out to determine the effects of sulfur and phosphorus application and rhizobium inoculation for a chickpea variety, Aziziye-94, under Eastern Turkey conditions in 2004 and 2005. The trial was laid out in split-split block design with three replications. Chickpea variety was applied on three different sulfur levels (0, 50 and 100 kg ha-1), phosphorus levels (0, 40 and 80 kg ha-1) and inoculation (inoculated and uninoculated). Whereas the highest grain yield were obtained from 80 kg ha-1 P with 819 kg ha-1 from 100 kg ha-1 S with 758 and from inoculation with 723 kg ha-1. In the first year, they were obtained from 80 kg ha-1 P with 879 kg ha-1 from 100 kg ha-1 S with 818 and from inoculation with 784 kg ha-1 in the second year. Nutrient uptake by grain of chickpea significantly increased due to sulfur doses, except for P uptake in grain at the year of 2004 and S uptake in grain at the year of 2005. Sulfur application significantly increased the uptake of Fe, Mn, Zn and Cu in grain in the both years. The effects of different doses of phosphorus application on nutrient uptakes by grain were found to be statistically significant in both years. © 2008 Academic Journals.
Nitrogen Levels and Application Methods Affect Weed Biomass, Yield and Yield Components in 'tir Wheat (Triticum Aestivum)
(Rsnz Publishing, 2009) Togay, N.; Tepe, I.; Togay, Y.; Cig, F.
Nitrogen (N)fertilisation is an important component of integrated weed management systems in wheat (Triticum aestivum). This study was conducted to determine the effects of N and application methods on the weed-crop competition in 'Tir' winter wheat (T. aestivum var. leucospermum) in the absence of herbicide. The trial was conducted in a factorial randomised complete block design with 4 replications in 2 years (2005-06 and 2006-07). Three N rates (0, 60, and 120 kg N ha(-1)) and three application methods ((I) broadcast on the soil surface; (2) banded 10 cm broadcast between every crop row; and (3) banded 10 cm deep between every crop row) were applied. Weed flora composition and density, weed biomass, grain yield, biological yield, plant height, spike length, number of seeds per spike, 1000 seed weight, and protein ratio in grain and shoot were investigated. The differences between treatments for weed density were not significant in either year. However, application of N up to 120 kg ha-1 increased total weed biomass to 1020 and 2009 kg ha(-1) in the 2 respective years, whereas weed biomass of 643 and 862 kg ha(-1) was obtained with 0 N ha(-1). Greatest weed biomass was recorded with N applied by broadcast and banded between crop rows, whereas weed biomass was least for N banded 10 cm deep with values of 722 and 1139 kg ha(-1) in 2 successive years. Highest grain yields were obtained with 120 kg ha(-1) N (1568 and 1190 kg ha(-1)) and for N banded 10 cm deep (1263 and 1132 kg ha(-1)) in the 2 successive years, respectively. Information gained from this study will be used to develop more efficient fertilisation levels and application methods in winter wheat as components of integrated weed management in the absence of herbicide.
Nutrient Status and Yield of Chickpea (Cicer Arietinum L.) as Influence by Application of Different Harvest Timing and Sulphur Fertiliser
(Scibulcom Ltd, 2015) Dogan, Y.; Togay, N.; Togay, Y.
The objectives of this research were to study the effect of harvesting time and sulphur levels on the yield, protein and mineral nutritional value of chickpea seeds. Three different harvesting times (early, on-time and late) and four sulphur levels (0, 20, 40 and 60 kg ha(-1)) were used. Yield, protein ratio and mineral nutritional value of chickpea were significantly affected by sulphur and harvest timing. The highest grain yields according to the harvest time were obtained from on-time harvest with 1527 and 1434 kg ha-1 for the first and second years, respectively. The lowest grain yields were obtained from the control plots, whereas the highest values were obtained from the plots given 60 kg he sulphur. Generally, protein, phosphorus, calcium, magnesium, copper, zinc, and manganese concentrations of the seeds in on-time harvest and 60 kg ha(-1) sulphur aplication were found to be greater than in early and late harvested plants. Positive significant relationships were found between harvest time and protein (r = 0.64**), Fe (r = 0.75**) and Zn (r = 0.27*). Positive significant relationships were found between sulphur doses and grain yield (r = 0.44*), protein (r = 0.26*), P (r = 0.71**), K (r = 0.73**), Ca (r = 0.36**), Mg (r = 0.76*), Zn (r = 0.57) and S (r = 0.96*).

(indian Counc Agricultural Res, 2008) Togay, Y.; Togay, N.; Erman, M.; Dogan, Y.
An experiment was carried out during 2004 - 05 to study the effect of different doses of phosphorus (10, 40 and 80 kg/ha) and sulphur application (0, 40, 80 and 120 kg/ha) on yield and quality of dry bean (Phaseolus vulgaris L.). The trial was conducted in factorial randomized complete block design with 3 replications. The highest grain yield was recorded with 80 kg/ha P and 120 kg/ha S applications, being 1.530 tonnes/ha in the 2004 and 1.606 tonnes/ha in 2005. The highest phosphorus content (0.29 % in 2004 and 0.30 % in 2005) in grain was observed when 80 kg/ha P and 120 kg/ ha S were applied.
