Ülkemizdeki nüfus artışına bağlı olarak hayvansal proteine duyulan ihtiyaç da artmıştır. Bu ihtiyaçların karşılanabilmesi için eldeki mevcutların iyi bir şekilde değerlendirilmesi gerekir. Herkesin hayvansal kaynaklı proteine kolay ve ucuz olarak ulaşabilmesi ancak hayvancılığın en büyük girdisi olan yemi ucuz olarak sağlayan meraların doğru ve düzenli olarak kullanılmasına ve yem bitkisi üretim alanlarının artırılmasına bağlıdır. Meraları doğru kullanmak için öncelikle merada otlayacak hayvan kapasitesinin bilinmesi, kapasite üstü hayvanlarla otlatmanın yapılmaması ve daha da önemlisi otlatma mevsimine bağlı kalınması gerekir. 2019 yılında Elazığ’da 232.411 BBHB varlığının olduğu, buna karşın yem değeri düşük kaba yemlerde dahil edilse dahi 534.082.634 kg yem açığı olduğu görülmektedir. İl’in toplam tarım alanının %3.6’sında yem bitkisi üretimi yapıldığı, bu oranın gelişmiş ülkelerin çok çok gerisinde kaldığı, yem açığının giderilmesi için acilen yem bitkisi üretim alanlarının artı...

Caperseed has poor germination because of the seed coat dormancy Germination of caperseeds are complex traits affected by a wide range of intemal and environmental influences. The effects of temperature preconditioning and period on germination of Capparis ovata were examined. Experiments were conducted in order to investigate germination behaviour of caperseeds subjected to different temperature and duration. The experiment revealed that the different temperature treatments were effective on mean germination percentage. The highest mean germination were obtained at 0 degree C 29.52% and 10 degrees C with 27.17% and the lowest mean germination were obtained at control seeds with 8.39%. Dry heat treatments effected germination rate, but it was not enough for removing germination obstacle of caper seed completely.

Drought is a major stress factor for agricultural production including alfalfa production. One way to counterbalance the yield losses is the introgression of drought tolerant germplasm into breeding programs. As an effort to exploit such germplasm, 16 individual plants were selected from the Southeastern Turkey from their natural habitat and clonally propagated in field trials with an ultimate goal to use the germplasm as parents for releasing a synthetic cultivar. Forage yield and forage quality traits were evaluated and molecular genetic diversity among genotypes were determined using inter simple sequence repeat markers. Genotypes showed a variation from growth habit to yield and quality traits indicating sufficient phenotypic variation for diverse breeding efforts (for grazing or harvesting) and long term selection schemes. A large amount of genetic variation was observed even with a limited number of marker and genotypes. However, no pattern of spatial genetic structure was obs...

Geliş Tarihi:23/02/2004 ÖZET Bu çalışma, 1998 ve 1999 yıllarında Diyarbakır Övündüler (Yukarı Ervanlı) Köyünde otlatılan ve otlanmayan meraları karşılaştırmak amacıyla yürütülmüştür. Meralar; Karacadağ'da ve Diyarbakır'a 40 km mesafededir. Otlanmayan mera hayvanlardan korumak amacıyla telle çevrilmiştir. Korunan alanda 7 familyaya ait 33 bitki türüne rastlanırken, otlatılan alanda 6 familyaya ait 26 bitki türüne rastlanmıştır. Otlatılmayan alanda bitki ile kaplı alan % 86.48 olurken, bu değer otlatılan alanda %70.82 olarak belirlenmiştir. Araştırma sonuçları değerlendirildiğinde, otlatılan alanda bitki ile kaplı alan, familya tür ve sayıları bakımından korunan alana göre daha düşük bulunmuştur. Familya grupları oransal olarak incelendiğinde ise baklagillerin otlatılan alanda önemli derecede azaldığı, diğer familyalardan olan bitkilerin baklagiller kadar olmamakla beraber azalma gösterdiği, buna karşın buğdaygillerin artış gösterdiği tespit edilmiştir.

The purpose of this study was to examine applied rangeland improvement and management studies carried out from 2004 to 2011 in six provinces of the Southeastern Anatolia Region of Turkey. The aims of the studies were to (1) protect and conserve rangeland soil and water resources, (2) improve and strengthen weakened rangeland vegetation, and (3) increase hay yields and grazing capacities of the rangelands. Additionally, one of the most important goals of these studies was to enhance the cultivation of forage crops in cultivated areas in order to decrease the adverse effects of overgrazing and to supply quality roughage for livestock. To achieve these objectives, different rangeland improvement methods and rangeland management strategies were applied in 40 different rangelands in the region. The results indicated that the average sufficient rangeland area per animal unit was 1.99 ha, whereas the value recorded prior to these studies was 4.80 ha.

The study was conducted to determine seed yield and its affecting components in Hungarian vetch (Vicia pannonica CRANTZ) genotypes in ecological conditions of Kızıltepe Plain, one of the hottest and driest places in the Southeastern Anatolia Region of Turkey, in the scope of forage crops research studies of Rangelands and Forage Crops Unit of Diyarbakır GAP International Agricultural Research and Training Center. For this aim; the research was carried out during 2009-10 growing season with winter sowing in the farmer field of Çağıl Village, Kızıltepe, Mardin, according to randomized block design with three replications. Statistically highly significant differences (P < 0.01) were found among genotypes in terms of all of the examined traits. The examined traits were changed among the genotypes as follows; days to physiological seed maturity 180.7-188.7 days, pod numbers per plant 8.93-24.93 pod plant-1, seed numbers per pod 2.33-4.57 seed pod-1, biological yield 285.0-450.7 kg da-...
In order to break seed dormancy, different temperatures (20, 30, 40, 50, 60, 70, 80 and 90o C) and durations (10, 20 and 30 minutes) were applied to black locust (Robinia pseudoacacia L.) and honey locust (Gleditsia triacanthos L.) seeds,... more
In order to break seed dormancy, different temperatures (20, 30, 40, 50, 60, 70, 80 and 90o C) and durations (10, 20 and 30 minutes) were applied to black locust (Robinia pseudoacacia L.) and honey locust (Gleditsia triacanthos L.) seeds, in the Seed Laboratory of Dicle University - Faculty of Agriculture in 2009. According to the research results, the highest germination rate for black locust seeds was obtained in the case of 90o C for 30 minutes pre-treatment (94.5%), whilst the lowest value was obtained for the 40o C for 10 minutes pre-treatment (7.5.0%). For honey locust the highest value was obtained at 50o C for 30 minutes (25.5%) and the lowest value was obtained in the case of control sample (6.8%).

Native Achillea plants (A. biebersteinii, A. aleppica, A. tenuifolia, A. magnifica, A. cucullata) were collected from nine localities of Southeastern and Eastern of Turkey during the flowering period. The essential oils of five Achillea species were obtained by hydrodistillation and analysed by GC-MS. Generally the principal constituents of the oils were 1,8 cineol+ascaridol, camphor, isoascaridol, 1,8 cineol and camphor as A. biebersteinii, A. aleppica, A. tenuifolia, A. magnifica, A. cucullata, respectively. Chemical composition of essential oils of Achillea species are highly variable, which may be due to the differences in their chemical polymorphic structure and environmental conditions.

ABSTRACT In the present study, some agricultural characteristics were investigated on 6 red clover cultivars obtained from various resources, between 1999 and 2001, under irrigated conditions in Diyarbakir. The average values of the three years for red clover cultivars showed that the green herbage yield varied from 3615.9 to 4649.9 kg da-1; dry herbage yield from 868.5 to 1254.2 kg da-1; the height of the plants from 26.78 to 32.20 cm and their protein ratio from 15.82 to 17.43%. Among all the cultivars, D-282 had the highest herbage yield and plant height, followed by Colenso, G-27 and Pawera. The lowest herbage yield was obtained from D-259 and Turoa cultivars. The highest protein content was obtained from Turoa (17.43%) although there was no significant differences among the cultivars.
