Sarilop) leaves Şahin, Berrin; Çobanoğlu, Ferit; Ertan, Birgül; Konak, Ramazan; Tutmuş, Eşref; Belge, Aytekin; Çokuysal, Burçin In that project, it has been aimed to determine method of using that olive oil vegetation water as on organic manure in dried fig production and to obtain positive solution for environmental pollution. Fig and olive are important agricultural products in Aydin province. It has been accepted that reducing of crop nutritient quantities in agricultural lands is caused negative effect on dried fig product quality and yield. The oil vegetation water which is occurred in olive oil factory is caused very serious environment pollution. That project will be carried out in 2006-2012 years. The study is conducted in a farmer orchard which has 80 ‘Sarilop’ dried fig trees, located in Isafakilar village, Incirliova, Turkey. This experiment was designed in respect of randomized blocks with four replications and each replication was consisted of two trees. Totally five applications are on the carpet, those olive oil vegetation water applications include control, 25, 50, 75, 100 kg/per tree, respectively. In addition, there are two groups that determined implementing olive oil vegetation waters in every year and every two years (implementing one year and no implementing one year). According to 2006-2007 periods results; it has been defined that olive oil vegetation water applications are composed some dissimilarities on some physical and chemical properties in the soil. However, similar variations weren’t seen on leaf analysis.

However, in the absence of proper management, it’s excessive in the water resources could have negative impact on water quality and may cause environmental as well as health complications. To evaluate the nitrate concentrations in groundwater resources in Gorgan area, north of Iran, 47 water samples were taken from different groundwater resources of shallow and deep wells as well as streams. The results showed that nitrate concentrations varied from 0.44 to more that 36 mgL- 1showing different pattern in different resources. In deep wells (wells with the depth of more than 50 meter), nitrate concentrations varied from 1.77 to 12.4 mgL-1 with an average of 5.8 while nitrate concentrations in shallow wells (wells with the depth of less than 50 meter) varied from 0.44 to 36.32 with an average of 13.37 mgL-1 . The corresponding data for streams was found to be varied from 3.54 to 27.9 mgL-1 with an average of 15.84. The results showed that nitrate concentrations was clearly greater in shallower groundwater resources compared to deeper ones showing increase of nitrate accumulation risks due to intensive agricultural activities in these area. The trends of nitrate accumulation showed that water resources is becoming more susceptible since they are the main drinking as well as agricultural source of water in the area. It seems that proper management in terms of fertilizers use and irrigation would be necessary to decrease the risk of nitrate accumulation in water with more emphasis to shallow water resources in the area.

For this purpose, the heavy metal level of the leave and soil samples taken in each season from olives is stated. The minimum heavy metal level is found in Yatagan, and the maximum in Yeniköy. The heavy metal level of the soil samples generally increases in autumn. The level of the leave samples has generally its highest levels in winter. Because Lignite includes low calorie and high sulphur and ash and especially Yatagan becomes demoded, the pollution continues to pose a serious threat in the precinct.

A.; Haq, A. A pot experiment was conducted in green house to evaluate the performance of two maize genotypes using saline or / sodic water with and with out amendments. There were eight treatments T1 (control with EC 1.07 dS m-1, SAR 1.63, and RSC 0 me L-1), T2 (EC 2.4 dS m-1, SAR 16 (mmol L-1)1/2, and RSC 2.25 meL-1 ), T3 (EC 3.6 dS m-1, SAR 24 (mmol L-1)1/2, and RSC 4.5 meL-1), T4 (T2+ Gypsum on irrigation water basis), T5 (T3+ Gypsum on irrigation water basis),T6 (T1+ FYM @ 20 Mg ha-1),T7 (T2+FYM @ 20 Mg ha-1),T8 (T3+ FYM @ 20 Mg ha-1) . Saline or/ sodic water were prepared with the help of quadratic equation and recommended doses of NPK fertilizers were used. Chlorophyll content was recorded after 40 days of sowing and fully expanded younger leaf were collected and stored in separate polypropylene tubes for sap extraction. The experimental results showed that chlorophyll content, Leaf area plant-1, plant height, fresh weight of plant, dry weight of plant of all genotypes decreased significantly with increasing levels of saline or /sodic water but this decrease was minimum when gypsum and FYM was applied. Na+ concentration of all genotypes increased significantly and decreased with gypsum and FYM application. Potassium and K+: Na+ ratio of all genotypes decreased significantly with increasing levels of saline or / sodic water but increased when gypsum and FYM was applied. ECe, SAR and pHs in soils after harvesting of crop increased also significantly. The application of FYM and gypsum proved to much helpful in improving soil quality and crop productivity.
