Öğe DETERMINATION OF WATER-EFFICIENCY RELATIONSHIPS AND SILAGE QUALITY CHARACTERISTICS OF THE MAIZE SPECIES FOR SILAGE(ZEA MAYS L.)THE FIRST PRODUCT GROWN UNDER SEMI-ARID CLIMATE CONDITIONS(2016-10-28) Uçak, Ali Beyhan; Gençoğlan, Cafer; Bağdatlı, M.Cüneyt; Turan, Nizamettin; Arslan, Hüseyin; İnal, BehçetIn this study, a field study was carried out to determine the effect of different irrigation water amounts on dry matter efficiency and silage quality features of species of corn for silage P32K61, P31Y43, P30B74 and the relationship of water and dry matter, as well as the threshold value of the dry substance to be used in silage quality estimation by leveraging such relationship. The study was planned as three repeats in a trial pattern of divided parcels in randomized blocks. Irrigation program was established by reapplication of 100% (I100), 70% (I70), 35% (I35) of the water consumed every 7 days with the drip irrigation method. Thus, the irrigation consists of 1 full and 2 different deficit irrigation. In the study, irrigation water amount applied to I100,I70 and I35 of types P32K61, P31Y43 and P30B74 was 637-653-666; 491-495-509; 342-363-371 mm, respectively, seasonal plant water consumption values were 705-714-738; 559-554-583mm, dry matter efficiency values ranged from 24.38-24.29- 32.36, 23.26-23.33-25.5, and 12.8-14.46-14.13 t ha- 1 . Linear relations were determined between dry matter (DM) efficiency of the species and irrigation water (I) as DM=20.57I+6369(r2=0.997**), DM=30.95I+4340(r2=0.999**),Y=36.14I+5826 (r2=0.998**);and between dry matter-plant water consumption (ETa) values as Y=26.02ETa+832.1(r2=0.969**),Y=36.55ETa- 22.83 (r2=0.995**), Y=42.75ETa-1949 (r2=0.997**). The highest and lowest protein amounts by irrigation were 8.67% in the interaction of I100 irrigation and P32K61 species and 6.14% in the interaction of I35 irrigation and P31Y43 species, respectively; digestible dry matter ratio was 70% in the interaction of I100 irrigation and P30B74 species and 60% the interaction of I35 irrigation and P31Y43,respectively. No statistically significant relation between the ADF (Acid Detergent Fiber) and NDF (Neutral Detergent Fiber) values was found. The highest water consumption efficiency was 4.38 kg/da-mm in I100 irrigation and 3.37 kg/damm in I35 irrigation. In addition, thecorrelation coefficient between ET, dry matter and protein amount was r 2 :0.81** and r 2 :0.80**, and a statistically significant positive relationship was observed (p<0.01) between ETa, dry matter and protein amount. As a result of statistical and economic analyses, threshold dry matter efficiency value on which the silage quality starts to drop was determined at 25.5 t ha-1 in I70 irrigation.Öğe Effects of treatments of gibberellic acid, citric acid and stratification on germination of seeds of Salvia siirtica Kahraman, Celep & Doğan sp. nov. (Lamiaceae)(Journal of Applied Biological Sciences, 2017) Arslan, Doğan; Çığ, Arzu; Arslan, Hüseyin; Bayraktar, Önder Volkan; Tülücü, FarukSalvia siirtica Kahraman, Celep & Doğan sp. nov. (Lamiaceae) have been recently reported as a new species from southeaster Turkey. It is currently grown in remote areas, where locally adapted and sparsely populated. The study will be of paramount importance for understanding of germination behavior in Salvia siirtica, possibly due to encouraging its propagation, but not being endangered. For this reason, conducted a study, consisting of a set of germination tests, under the tissue culture laboratory. In this study, Salvia siirtica seeds were treated with gibberellic acid (24 h and 48 h in GA3 of 250 mg l-1), citric acid (5 and 10 min in its solution of 4 %) and stratification (14 and 28 day in fine sand maintaining in refrigerator of + 4 °C). Experiment was set up in completely randomized factorial design with three replications. Comparing with control, sole gibberellic acid treatment or combined with other treatments had no effect on Salvia siirtica germination and rooting behavior. But, combined effects of citric acid and stratification treatments were statistically significant (p<0.01). The highest germination and rooting rates (21.25 and 17.97 %, respectively) were measured on stratification treatment of 28 day.Öğe Effects of treatments of gibberellic acid, citric acid and stratification on germination of seeds of Salvia siirtica Kahraman, Celep & Dogan sp. nov.

Genotiplerinin Belirlenmesi(2017) Hatipoğlu, Halil; Arslan, Hüseyin; Karakuş, Mehmet; Abrak, ServetBu araştırma, bazı susam hatları ile Arslanbey ve Özberk-82 susam çeşitlerinin Harran Ovası koşullarındaki II. ürün performanslarını belirlemek amacıyla, 2010 ve 2011 yetiştirme sezonlarında GAP Tarımsal Araştırma Enstitüsü Müdürlüğünün Talat Demirören Araştırma İstasyonunda yürütülmüştür. Deneme tesadüf blokları deneme desenine göre 3 tekerrürlü olarak kurulmuştur. Parsellerde; sıra arası mesafe 70 cm, sıra üzeri mesafe ise 15 cm olacak şekilde her parselde 4 sıra ekim yapılmış olup, parsel ebatları 6 x 2.8 m olarak düzenlenmiştir. Denemelerde bitki boyu, bitki başına yan dal sayısı, bitki başına kapsül sayısı, tohum verimi ve 1000 tane ağırlığı gibi bitkisel özelliklere ait gözlemler yapılmıştır. İki yıllık birleşik analizlerde; genotipler arasındaki farklılıklar incelenen tüm bitkisel özelliklerde % 1 seviyesinde önemli bulunmuştur. Araştırma sonuçlarına göre; en yüksek tohum verimi 1233 kg ha-1 ile Arslanbey çeşidinden elde edilirken, en düşük tohum verimi ise 574 kg ha-1 ile 3 no'lu hattan elde edilmiştirÖğe PERFORMANCES OF SESAME GENOTYPES (SESAMUM INDICUM L.) WITH DIFFERENT SEED SHELL COLORS IN SEMI-ARID CLIMATE CONDITIONS(Fresenius Environmental Bulletin, 2018-12-27) Arslan, Hüseyin; Ekin, Zehra; Hatipoğlu, HasanThis research was conducted to determine the adaptability of some sesame (Sesamum indicum L.) varieties as a second crop under semi-arid climatic conditions during 2014 and 2015. The experiment was conducted on the research area of Agricultural Faculty, Kezer Campus, Siirt University, Turkey. Thirteen registered sesame species were used as material in the experiment. The experiment was carried out in a randomized block design with four replications. Planting of sesame seeds was performed by hand following the harvest of wheat planted as the first crop. The plant height, number of side branches in the plant, the first branch height in the plant, the number of capsules per plant, the number of seeds per capsule, the weight of 1000 seeds, seed yield, fat content, fat yield and protein content were determined in the study. The results of two-year study revealed that 10 out of 13 varieties were not suitable to semi-arid climatic conditions (Siirt province ecological conditions). The varieties which were not adopted to semi-arid climatic conditions (Tan 99, 6DUÕVX 7DQDV g]EHUN .HSVXW 0XJDQOÕ 57, Baydar 2001, Ottoman 99, Orhangazi 99 and Cumhuriyet 99) are widely cultivated sesame cultivars in the Aegean and Mediterranean regions. The other WKUHH YDULHWLHV $UVODQEH\ +DWLSR÷OX DQG %R\GDN are mostly recommended for the Southeastern Anatolia Region. The study clearly revealed the importance of genotype x climate interaction in adaptation of sesame species to a region.
