    Effects of different types and levels of zinc sulphate applications in vineyards (Vitis vinifera L.) in a semi-arid environment
    (Chemical Publishing Co., 2007) Aydin Ş.; Yaǧmur B.; Hakerlerler H.; Çoban H.
    The present study was carried out to determine the effect of soil and foliar applications of different rates of zinc in the vicinity of Alaşehir, one of the most important viticultural centres in the Westem Aegean Region where the round seedless grape cultivar (Vitis vinifera L.) is widely grown, on productivity and some chemical quality characteristics as well as leaf primary and secondary elements. Zinc was applied to soil and foliage as ZnSO4·7H2O in the experiment with four replications. One soil application (0-15-30-45 g ZnSO4·7H 2O/vine) in addition to foliar application replicated three times (0.0-0.025-0.050-0.10% Zn). Both soil and foliar zinc sulphate (ZnSO 4·7H2O) applications increased the amount of fresh grapes per vine.The highest yield was observed at 30 g ZnSO4· 7H2O level per vine in soil application and at the rate of 0.05% Zn in foliar application. Zinc sulphate produced a significant positive effect on the contents of primary and secondary elements (N, P, K, Ca, Mg, Fe, Zn, Mn, Cu) of the leaf (lamina and petiole) with the exception of the leaf petiole manganese content in the soil application and the leaf petiole copper content in the foliar application. Soil and foliar applications of zinc sulphate negatively affected the firmness of the berry flesh. The only fruit quality characteristic positively affected by soil and foliar applications of zinc sulphate was the amount of total soluble solids. Despite the fact that the soil application of zinc sulphate did not have any significant effect on some sugar fractions, the foliar application increased only the fructose and α-glucose significantly. In conclusion, it was established that foliar application of zinc sulphate was slightly more effective on yield as well as some quality characteristics as compared to soil application. Therefore, it was concluded that foliar application could be preferred as it is more economical and easier to apply.

    EFFECT OF ORGANIC FERTILIZATION ON FIG LEAF NUTRIENTS AND FRUIT QUALITY
    (2013) Mordoǧan N.; Hakerlerler H.; Ceylan Ş.; Aydin Ş.; Yaǧmur B.; Aksoy U.
    Turkish dried fig (Ficus carica L.) production plays a major role in the world trade due to its volume and quality. The production is generally realized from orchards on steep slopes under rain-fed conditions. Birgi-İrimaǧzi{dotless} in Ödemiş has peculiarities in respect to dried fig production. In this region, colluvial soils require additional late-winter irrigation by flooding especially in years because of inadequate winter rainfall. Organic dried fig production has gained importance since mid 1980s. The research work aimed at testing the effect of sheep and cow manure mixtures (at two different ratios: 1:1 and 2:1) on leaf and fruit nutrient contents, vigor, and fruit quality. The results proved that tree vigor and fruit quality were improved with the applied rates of farmyard manure, where as the effect on nutrient content of the leaf was not marked. © 2013 Copyright Taylor and Francis Group, LLC.
