The aim of the study was to evaluate appropriate nitrogen rates on some cowpea cultivars in case of no native Rhizobia population in soil or rhizobia inoculant was not applied. The research was ...conducted at Mediterranean climate conditions in Turkey during 2012/2013 and 2013/2014 cropping seasons. The experiment was laid out in randomized block on the basis split plot design with three replications at the end of April in both year. Three registered cowpea cultivars namely Amazon, Srrma, Karagoz with originated Turkey were used as a research material and three rates of nitrogen level (80 kg, 120, 160 kg N ha-1 ) were applied. Plant height (em), branches plant-1 pods m-2 , seeds pod-1 100-grain weight (g), grain yield (kg ha-1) were investigated. Applications of total 12 kg N ha-1 (before sowing and during the stage of seedling) in cultivars Amazon and Karagoz were optimum level for higher grain yield (2629 kg ha-1 and 3070 kg ha-1 respectively).
The present study was conducted to determine appropriate selection criteria in field pea breeding material under Mediterranean conditions. The experimental material was 14 lines obtained with ...selection by us from populations provided ICARDA and 6 registered pea cultivars. The experiment was organized in randomized blocks design with three replications. Genetic variability, heritability, genetic advance and path coefficient analysis were estimated for some quantative traits. High heritability coupled with high genetic advance was observed for plant height and 100-seed weight and seeds number per plant. The highest positive direct effect on seed yield was observed for 100- seed weight followed by seeds per plant and pods per plant. Days to flowering, plant height and harvest index had a great indirect positive effect on seed yield per plant through 100-seed weight and seeds number per plant.100-seed weight and seeds number can be used as a selection criteria for improving seed yield per plant in field pea breeding material.
The present research was conducted to determine the effect on the yield and yield components of different seeding systems of wheat and pea intercropping at the Research Area of Field Crops Department ...of Agricultural Faculty within Cukurova University. Field trails were organized in randomized complete blocks design with four replications at the end of November in 2014 and 2015. Grain yields in the intercropped pea and wheat were less than sole crops. Increasing pea rate in the mixture seeding provided good competition with wheat. The highest grain yield of intercropped pea was found in the intercrops including 85% of pea seeds in alternate row in both years and combined years. Total grain yield of intercrops was higher than sole crop pea, but it was lower than sole crop wheat. Total grain yield of intercrops including 50 % pea at the same row was higher when compared to the other intercrops in both of years and combined years. On the other hand, it was found that generally, LER value for grain in the intercrops was greater than 1 and intercrops use environmental sources such as water, soil, and light for plant growth factors more efficiently than the sole crops for grain production.
The present study was carried out to evaluate appropriate selection criteria for improving seed yield in chickpea breeding material under rainfed condition. For this reason, extent of genetic ...variability, heritability and path coefficient analysis were estimated for chickpea breeding programme. The present study was conducted with twelve genotypes for three years at the Mediterranean climate conditions in Turkey.ôThe experiment was arranged in randomized block design with 3 replications. Genetic parameters and path coefficient analysis were determined for some quantitative characters. The highest broad sense heritability was found for 100-seed weight (86.22%). High heritability for 100-seed weight and height of first podding node coupled with high genetic advance was estimated. The highest direct effect on seed yield per plant was number of seeds/plant (82.1%) followed by 100-seed weight (46.6%). Number of full pods per plant, number of branches per plant had a great indirect effects on seed yield per plant. Conclusions it can be said that yield of chickpea should be improved by selecting plant with higher number of seeds per plant and 100- seed weight.
The aim of the present study was examined for genotype x environment interactions, stability performance and adaptability of 18 chickpea genotypes for grain yield and yield components under ...ecological conditions of the Mediterranean of Turkey. The genotypes were evaluated in randomized complete block design with three replications at two locations during two years. Genotype-environment interactions were significantly found for grain yield and all the yield components. Stability parameters revealed that Cevdetbey and Seçkin were found to be fairly stable for days to flowering under all the environments. None of the genotypes with high mean were highly stable over environment for grain yield and number of pods per plant. The genotype Seçkin was quite stable across all environment for plant height. Canitez was stable for number of grains per plant. Seçkin and Er for 100- grain weight showed relatively stable performance over all environment.
The present experiment was conducted to determine magnitude of genetic variability with fifteen kabuli chickpea genotypes in the 2013/2014 and 2014/2015 growing season under Mediterranean climate ...conditions. In this present study seed yield per plant and yield component were investigated. The experiment was orginazed with three replications in randomized complate blocks design. Data were recorded on plant height, number of branches per plant, height of first podding node, full and total pods number per plant, seeds number per plant, 100-seed weight and seed yield per plant. Analysis of variance for seed yield per plant and its component showed significant differences among all genotypes. Broad-sense heritability ranged from 12.27% (total pod number per plant) to 93.88% (100-seed weight). Moderate and high estimates of broad sense heritability were observed for branches number per plant, harvest index and 100-seed weight. It can be concluded that the seed yield of chickpea can be improved by selecting these characters in breeding chickpea materials.
GAP (Güney-doğu Anadolu Projesi) ve Çukurova bölgelerinde artan hayvan populasyonu için yem bitkileri üretiminin artırılması
zorunludur. Yüksek verimli yaygın fiğ (Vicia sativa L.) çeşitlerinin ekim ...nöbeti sistemleri içerisinde yetiştirilmesi, özellikle kış
dönemlerinde belirgin olan yem açığını azaltacaktır. Bu araştırmanın amacı 15 yaygın fiğ hat ve çeşidinde ot verimi bakımından genotip
çevre interaksiyonu ve stabil genotipleri saptamaktır. Fiğ genotipleri, Çukurova bölgesinde 2 lokasyonda (Balcalı ve Doğankent) 3 yıl,
GAP bölgesinde bir lokasyonda (Akçakale) 2 yıl süreyle denenmiştir. Çukurova bölgesi çok daha iyi toprak ve iklim koşullarına sahipken,
GAP bölgesinde yağış bitki büyümesini sınırlandırmıştır. Lokal iklim değişikleri önemli olduğundan, her yıl ve her lokasyon ayrı bir çevre
olarak kabul edilerek toplam 8 çevre oluşturulmuştur. Genotip × çevre interaksiyonlarının analizi için linear regresyon teknikleri
kullanılmıştır. Genotip çevre interaksiyonu mevcut olduğunda, ot verimleri bakımından genotipler ve çevreler arasındaki farklılıklar
önemli bulunmuştur. Çevreler arasında varyasyon yüksek düzeyde önemli olup, ortalama kuru ot verimi 7453 kg ha-1 (Doğankent,
2002-03) ile 2687 kg ha-1 (Balcalı, 2003-04) arasında değişmiştir. V7 ve V12 genotipleri, regresyon katsayılarının 1'den ve
verimlerinin de genel ortalamadan daha yüksek olması nedeniyle iyi koşullara iyi adapte olmuştur. V5, V9 ve V10 genotiplerinin,
regresyon katsayıları 1'in altında, ortalama verimleri genel ortalamadan yüksek olması, bu genotiplerin kötü koşullara daha iyi adapte
olabileceğini ve çevre değişiklerine karşı hassas olmadıklarını göstermiştir. Çalışmamız, daha önceden seçilen genotip ve çeşitlerin GAP
ve Çukurova koşullarında başarılı bir şekilde yetiştirilebileceğini ve yem üretimine önemli katkı sağlayacağını göstermiştir.
Improving forage production for an expanding livestock population is essential in the Çukurova and GAP (South-eastern
Anatolia Project) regions of Turkey. Feed shortages, especially evident during winter, can be alleviated by introducing high yielding
common vetch (Vicia sativa L.) cultivars into crop rotations. The objectives of this research were to determine the genotype ×
environment interactions and stability parameters for hay yield of 15 vetch lines and cultivars. The vetch genotypes were evaluated
in the Çukurova (2 locations for 3 years) and South-eastern Anatolia (1 location for 2 years) regions. In the South-eastern Anatolia
region, the rainfall limits plant growth, while the Çukurova region has much better soil and climatic conditions. Since local climatic
variation is significant, each location in each year is treated as a separate environment, to give 8 environments. Linear regression
techniques were used to analyse genotype × environment interactions (G × E). The hay yield was significantly different between
genotypes and environments, while a genotype × environment interaction was present. The variation amongst environments was
highly significant, and the mean hay yield ranged from 7453 kg ha-1, in Doğankent (2002-03), to 2687 kg ha-1, in Balcalı (2003-
04). The genotypes 'V7' and 'V12', which had regression coefficients significantly greater than 1.0 and produced mean hay yields
above the overall mean, were well adapted to favourable environments. Three entries (V5, V9, and V10) possessed regression
coefficients significantly less than 1.0, with hay yield above the grand mean, suggesting that these genotypes were better adapted
to poor environments and insensitive to environmental change. Our study demonstrated that previously selected genotypes and
cultivars can be successfully grown and make a significantly positive contribution to animal husbandry in the Çukurova and Southeastern
Anatolia regions.

Alfalfa is one of the most important crops mainly grown for forage and hay production in the world. Present study was aimed to investigate the green herbage and hay yield as well as some quality ...parameters such as acid detergent fiber (ADF), neutral detergent fiber (NDF), digestible dry matter (DDM), crude protein, dry matter contents, organic matter, crude oil and raw fiber of 9 different alfalfa cultivars. This study was conducted during two consecutive years (2015 and 2016) at two locations in Turkey (Sivas-Center and Sivas-Altinoluk). The mean values of ADF, NDF, DDM, crude protein (CP), green forage yield and dry forage yield were 43.73%, 52.69%, 50.70%,19.71%, 59163 kg ha-1 and 13866 kg ha-1 respectively. Dry forage yield reflected a positive and highly significant correlation with plant height, number of tillers and fresh forage yield. The varieties called Delta and Azzura performed very well for both locations during the whole period of study and also expressed a great level of winter resistance. Kayseri is a local cultivar in Turkey and it is revealed to be poor in terms of all the studied traits. According to the results of the study, it was concluded that the cultivars, Delta and Azzura, could be successfully grown in the continental climate regions of Turkey, and they could be also used in the breeding program of alfalfa to develop alfalfa varieties with high winter resistance and high yield and quality of forage.
