    Effects of different types and levels of zinc sulphate applications in vineyards (Vitis vinifera L.) in a semi-arid environment
    Aydin, S; Yagmur, 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 Alasehir, one of the most important viticultural centres in the Western 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 center dot 7H(2)O in the experiment with four replications. One soil application (0-15-30-45 g ZnSO4 center dot 7H(2)O/vine) in addition to foliar application replicated three times (0.0-0.025-0.050-0.10% Zn). Both soil and foliar zinc sulphate (ZnSO4 center dot 7H(2)O) applications increased the amount of fresh grapes per vine. The highest yield was observed at 30 g ZnSO4 center dot 7H(2)O 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 a-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.

    THE EFFECTS OF DIFFERENT LEVELS OF Fe-EDDHA APPLICATIONS IN A VINEYARD (Vitis vinifera L.) IN THE SEMI-ARID ENVIRONMENT
    Aydin, S; Yagmur, B; Yegenoglu, ED; Simsek, H
    Most of the production of seedless grapes ( Vitis vinifera L.) in Turkey is covered by the Aegean region, mainly in Manisa Province. It accounts for a significant part of the export (80%). One of the widespread micro element deficiencies in the soils of the Aegean Region in Turkey is Fe deficiency (Fe chlorosis). The inorganic Fe salts applied into the soils or sprayed on the leaves and organic chelates containing Fe such as FeEDTA or FeEDDHA have been used to correct Fe chlorosis in recent years. The aim of this study was to determine the effects of different FeEDDHA dosages on some yield quality parameters (total soluble solids %, pH, titratable acidity %, total Fe and active Fe content in leaves) of fresh grapes and some macro-and micro elements (N, P, K, Ca, Mg, Fe, Zn, Mn, Cu, active Fe) in leaves. In the study, four different doses of FeEDDHA (0, 20, 40, 60 g(-1)) were applied to the soil. It was found that there was less N deficiency but more P and K deficiency in the vineyard. Moreover, Ca, Mg, total Fe, Zn, Mn, and Cu deficiency were not observed in the vineyard. The yield of fresh grapes increased with the iron content, with the most efficient result obtained at a level of 20 g(-1) FeEDDHA.

    EFFECT OF ORGANIC FERTILIZATION ON FIG LEAF NUTRIENTS AND FRUIT QUALITY
    Mordogan, N; Hakerlerler, H; Ceylan, S; Aydin, S; Yagmur, 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-rimaz in odemi 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.

    QUALITY PARAMETERS OF VINEYARD IRRIGATION WATER IN A SEMI-ARID REGION: THE PLAIN OF ALASEHIR, TURKEY
    Yagmur, B; Aydin, S; Okur, B; Coban, H; Simsek, H
    Production of seedless raisins is extremely important in Aegean Region in Turkey. The Plain of Alasehir in province of Manisa in Aegean Region is extremely important for seedless raisin production since 25% of the seedless raisin has been grown in this area. The irrigation water samples were collected from 13 different water distribution locations in the Plain of Alasehir. Results showed that pH and EC (electrical conductivity) values were in a reasonable range except EC levels from two locations were slightly high. The vineyard irrigation water in the region was classified as type of C3S1. It was suggested that, the salt content might be monitored continuously since salinity might increase in the soil through the end of the irrigation season. The most common cations were Ca++ and Mg++, and anion was HCO3-. Trace elements and heavy metals were under the risk limits except Mn was high in three locations. Boron was high in nine sampling locations. Overall, irrigation waters in the Plain of Alasehir were suitable for vineyard irrigation as long as the contents of boron and salinity were continuously monitored.

    THE NUTRITIONAL CONDITIONS AND SOME HEAVY METAL CONTENTS OF THE VINEYARDS IN A SEMI-ARID AREA
    Aydin, S; Yagmur, B; Coban, H; Simsek, H
    Turkey is one of the most important seedless raisin producers in the world market. Approximately, 82% of the seedless raisin has been produced in the western part of Turkey since the climate (semi-arid) of this region is very appropriate to grow seedless grape. More specifically, the Plain of Alasehir, located in the Gediz Basin in Aegean Region has been known its high quality seedless raisin production. About 25% of the seedless raisin of the entire Aegean Region is produced in the Plain of Alasehir. Therefore, the Plain of Alasehir region was selected to determine some heavy metal contents (Cd, Co, Cr, and Pb) and certain macro and micro element contents (N, P, K, Ca, Mg, Fe, Zn, Mn, and Cu) of the leaf samples obtained from the vineyards in the area. The plant samples from 13 vineyards were analyzed by collecting the samples across the first plant bunch during the veraison period. In terms of nutrition profile, N deficiency was detected in 15% of vineyards while P deficiency was determined in 38.5% of the vineyards. Similarly, Fe deficiency was detected in the 30.8% of the vineyards. The contents of Zn, Mn, Cu, K, Ca, and Mg were sufficient in all of the vineyards. Some heavy metal contents of the leaf samples were analyzed and it was found that there was no pollution for the Cd, Co, and Pb in all the vineyards. Cr pollution was not detected in 93.2% of the samples.
