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.

Effect of land configuration ways on soil moisture and sesame seed yield in Ethiopia

Sesame is an erect herbaceous annual plant with both single-stemmed and branched growth habits. Sesame seed yield is easily affected by soil moisture stress in semi-arid climate. Good vertisol management options that conserve moisture during dry spell period and drain excess moisture during wet periods is vital. Study area has limited rainfall therefore evidences on effect of land configuration ways on soil moisture and sesame yield is critical. A field investigation was conducted at Humera Agricultural Research Center (HuARC) during 2016 growing season in vertisol soil type. The experiment was laid out by randomized complete block design (RCBD) with three replication that consists of three land configuration ways or methods namely flat, ridge and furrow, and bed furrow. Sesame variety, Setit-1, was sown with 40 cm and 10 cm spacing between rows and plants respectively. The analysis revealed that land configuration methods had a significant effect on soil moisture and agronomic parameter. The highest sesame seed yield (558 kg ha-1) was recorded at ridge and furrow, while the lowest (400 kg ha-1) was found at the flat land configuration method. The ridge and furrow methods conserved best soil moisture for highest plant and seed yield performance.
