Silage corn has an important potential as second crop under irrigated lands of semi-arid regions. This research was conducted to determine silage yield and quality of some corn cultivars (Ada, Cadiz, Donana, Sagunto and Sakarya) grown after barley harvest using different sowing methods (direct and conventional) in 2014 and 2015 years in Eskisehir Plain. Investigated parameters were significantly different between years except for leaf ratio and neutral detergent fiber (NDF) content. In the first year, plant height, fresh forage yield, and Fleig point were higher than the second year but dry matter, crude protein, acid detergent fiber (ADF) content, cob ratio and pH were contrarily higher in the second year. Sowing method significantly affected all parameters except leaf ratio. Using direct sowing method increased cob ratio (40.3 %), dry matter (22.93 %), crude protein content (7.56 %), pH (3,76) and Fleig score (85.82) compared to conventional sowing method. Cultivars significantly varied in terms of plant height, cob ratio, dry matter, crude protein, neutral detergent fiber, acid detergent fiber, pH, and Fleig point. Considering the total silage yield and quality the domestic cultivar Ada, which seeds are common in the market, could be suggested after barley harvest for second crop production as long as sown conventionally in irrigated lands of Central Anatolia.

Boiss., Onobrychis dealbata Stocks, Onobrychis stewartii Baker, and Onobrychis cornuta (L.) Desv. under light microscopy (LM) and scanning electron microscopy (SEM) and made a comparison of shape, apertural types, and exine ornamentation of the pollen morphology of Fabaceae species. The pollen grains of Fabaceae are radially symmetrical, isopolar, mostly tricolporate, and rarely colpate or porate. The shape is commonly prolate to subprolate, or prolate-spheroidal, often prolate. Ornamentation is mostly reticulate, rarely rugulate or foveolate. These researchers defined 10 main pollen types for the family Fabaceae and placed the species Onobrychis in the Onobrychis stewartii type. The pollen morphology of 12 Onobrychis taxa [Onobrychis alba (Waldst. & Kit) Desv. subsp. alba, Onobrychis alba (Waldst. & Kit.) Desv. subsp. calcarea (Vandas) P.W.Ball, Onobrychis alba (Waldst. & Kit.) Desv. subsp. laconica (Orph. ex Boiss.

In this study, karyotype analysis of the species of Onobrychis sp. was undertaken using the squash method. The results showed that the chromosome number of Onobrychis tournefortii (Willd.) Desv., O. gracilis Besser, O. hypargyrea Boiss. is 2n = 14 and O. argyrea Boiss. subsp. argyrea Boiss., 2n = 16. The karyotype formula of O. tournefortii (Willd.) Desv. is 4m+3sm, of O. hypargyrea Boiss. and O. gracilis Besser 3m+4sm, and of O. argyrea Boiss. subsp. argyrea Boiss. 2m+ 5sm+1 st

The aim of this study was to compare a wild population of common vetch (Vicia sativa L.) collected from the Serinyol district of Antakya in the east Mediterranean coastal region of Turkey with a cultivar of common vetch (V. sativa 'Anadolu'), on somatic chromosome number and important agronomic attributes. Somatic chromosome counts from material collected from the wild population of Vicia sativa L. were consistently 2n = 10, while the cultivar had 2n = 12. There were no significant differences between wild and cultivated cytotypes in plant height, seed number or pod number, although the wild cytotype had significantly more branches, smaller seeds, higher hardseededness and lower germination rates.

In this study which was carried out during the 2015 summer season in Eskişehir, the flower, pod and seed characters attributed to yield components were investigated in 12 forage pea genotypes. They showed significant differences in terms of agronomic and morphological (flower, pod, and seed) traits. The highest fresh hay yield with 2171 kg/da and plant height with 106.6 cm were obtained from Populasyon-1. Crackerjack had lower values in some flower traits such as, whereas the higher values of pod and seed traits were obtained from cv. Rose. In addition, Population-1 included in the higher value group for standard petal width, keel petal length, calyx tube and teeth lengths, and flower length. Although cluster analysis did not reflect agronomic traits, the clustering resulted in four groups. The first group consisted of Özkaynak 1, 2, and 3 and Taşkent, Töre, and Population-2, which were the standard petal colour violet, light, and dark violet. Population-1 had both violet and white standard petal; however, it was included in the second group together with white-flowered Ulubatlı and Ürünlü according to cluster analysis. While Rose and Gölyazı were in the third group, Crackerjack was in the fourth group alone. There was a highly significant positive correlation between fresh hay yield and both standard petal width and length and flower length. Consequently, a hopeful result for summer growing in Eskişehir condition was obtained from Population-1. It was suggested that some flower characters can be used for pre-selection of yield-related traits in the evaluation of genetic diversity of pea germplasm through morphological trait.
