Grain yield and yield components of triticale upon application of different foliar fertilizers

En las estaciones de crecimiento de 2000-2001 y 2001-2002 se llevaron a cabo experimentos de campo para investigar los efectos de varios fertilizadores foliares comerciales contentivos de N, P, K y micronutrientes sobre el rendimientos variados entre años debido a la estación seca. Los resultados mostraron que los tratamientos foliares tuvieron efectos positivos significativos en ambos años sobre el rendimiento de grano, número de ramillas por rama, número de granos por rama, peso de 1000 granos e índice de cosecha. El fertilizador foliar más efectivo en rendimiento y componentes durante el estrés por sequía fue el Zn-15, una forma quelada ( EDTA) del xinc. Tanto NZN como ZnSO4 incrementaron el rendimiento de grano del tritical bajo condiciones sin estrés.

Microfungi in cultivated fields in Eskisehir provience (Turkey).

The soil microfungi flora was investigated in four locations of Eskisehir (Turkey). 56 soil samples were seasonaly collected from 14 stations in the areas of Karacahöyük, Bahçecik, OGU I, and OGU II. A total of 110 species belonging to 32 genera were encountered including Absidia, Acremonium, Alternaria, Aspergillus, Beauveria, Botryoderma, Chaetomium, Chrysosporium, Cladosporium, Eupenicillium, Eurotium, Fusarium, Geotrichum, Gliocladium, Gonytrichum, Metarrhizium, Mucor, Myrothecium, Paecilomyces, Penicillium, Phoma, Plectosphaerella, Rhizoctania, Rhizopus, Scopulariopsis, Septonema, Stachybotrys, Trichocladium, Trichoderma, Ulocladium, Verticillium, and Wardomyces. Twenty five species were more frequent (all locations) while twenty seven species were rare (only one sample). Mainly, Acremonium kiliense, Aspergillus ochraceus, A. terricola var. americanus, A. versicolor, Cladosporium cladosporioides, Fusarium oxysporum, F. solani, Gliocladium roseum, Penicillium chrysogenum, P. corylophum, P. expansum, P. griseofulvum, P. implicatum, P. restrictum, and Stachybotrys chartarum were the most common and abundant microfungi in all locations. Five species Aspergillus subsessilis, A. terreus var. africanus, Eupenicillium egyptiacum, Paecilomyces ramosus, and Penicillium novae-zeelandiae are likely to be newly recorded for Turkey. The microfungi number in Eskisehir soils was between 25,000-234,000 CFU/g (mean value at 126,375 CFU/g).
