Determination of root properties of saplings belong to two boxwood species (Buxus sempervirens and Buxus balearica) by image processing technique

The study was carried out to determine the root architectural characteristics of the one-year saplings of two species of boxwood (Buxus sempervirens L. and Buxus balearica Lam.), which are endangered and natural plants of Turkey, in the greenhouse environment using the WinRhizo root analysis program and scanner. Total root length (cm), root surface area (cm2), root volume (cm3), average root diameter (mm), number of tips, number of forks and number of root crossings were determined in the study. According to the results of the study, the increase in temperature and decrease in humidity values in the second year of both species were effective on the root architectural features. As a result of this effect, the second year root length (3810 cm), number of root tips (2299), number of forks (7007) and number of root crossings (696) increased, root diameter (1.4 mm), root surface area (2158 cm2) and root volume (8 cm3) decreased. As a result, it has been concluded that species can make changes in their root parameters to adapt to different conditions and their adaptability is high. In general, the best results in root architectural parameters were obtained from Buxus balearica on the basis of species.

Effect of pollinator cultivars on nutrient content in some Turkish hazelnut cultivars

The main objective of this study was to assess the pollen effects on macro and micro nutrition elements on hazelnut cultivars (Corylus avellana L.). Tombul, Palaz, Çakıldak, Foşa and Allahverdi were used as main cultivars while Tombul, Palaz, Çakıldak, Foşa, Allahverdi, Sivri, Kalınkara and Yassı Badem were used as pollinator cultivars. In the study, it was investigated that the pollinator cultivars caused changes in some nutrition elements. The effects of the applications on nitrogen, phosphorus and potassium content were found to be statistically significant. It was determined that the nutrition element with the highest rate in the examined hazelnut cultivars is potassium. It has been observed that the amount of potassium is high in Tombul-pollinator treatments. The potassium content of Foşa and Çakıldak weres found to be higher than other cultivars. In Palaz and Yassı Badem- pollination treatments, it has been observed that the Ca content is generally lower than other treatments. Fe content was found to be significantly higher in Palaz-pollination treatments. The highest Mn and Zn content was obtained from Çakıldak. As a result, it has been revealed that pollinators may have an effect on nutrient content.

Determination of suitable areas for organic production in Kelkit basin and mapping by geographical information systems

Kelkit Basin contains 17 districts within the boundaries of Tokat, Amasya, Gümüşhane, Giresun, and Sivas provinces. The Basin is located in the Middle Black Sea Region of Anatolia, at 40.9968 North, 30.8491 East, 36.0482 South, and 36.6943 West coordinates. The total area of the basin is 16.244,45 hectares. The altitude of the basin surrounded by high mountains ranged from 200 m (base of the valley) to 1200 m (high plain). The height of the mountains gradually increased from west to east until 2400 m. There is not any major industry establishment limiting the level of organic agriculture in the basin. The main livelihood of the people in the region is agriculture. Our study aimed to determine and mapping the suitable areas for organic agriculture in the basin. For this purpose, land surveys were conducted, point data were collected with GPS and the 1230-point value are calculated. On the calculation of point value, Land Use Capability, land pollution situation, erosion risk groups, and soil groups are used as criteria. In line with the regulation of organic farming practices, in the calculation the amount of pollution; intense agricultural activity, the impact of roads, settlement influence, water resources, the effects of soil pollution, and industrial-mining areas were taken into account. By using these calculated values, maps were created in the program ArcGIS (9.3) by analysis of IDW (Inverse Distance Weighted). According to the generated maps, the organic agricultural potential of the region was put forward.
