The Effect of Potassium Application on Sugar Beet (Beta vulgaris L.) under Salt Stress

Salt stress is an important type of abiotic stress that limits vegetative production in the world, particularly in arid and semi-arid climatic areas. The aim of this study is to mitigate salt stress damage in the sugar beet plant, which is an important part of crop production, with potassium application. An experiment was designed according to a design of random blocks with 4 different doses (10, 20, 40, 80 mg kg-1 K) of potassium and 3 different salt levels (0, 100, 150 mM NaCl) and 3 replicates. Leaf length, leaf width, fresh weight, malondialdehyde (MDA) content, membrane damage, relative water content was determined after harvest. The data obtained from the experiment were evaluated by one-way analysis of variance (One-Way ANOVA). According to the results of variance analysis, leaf width, leaf length, fresh weight, MDA content, membrane damage, relative water content were found to be statistically significant in salt x potassium interaction. Due to the positive effects of potassium on the parameters known to increase the plants%252339%253B stress tolerance, it is thought that it may be beneficial in reducing the salt stress in order to make the sugar beet less affected by salt stress

Potasyumun Domateste Kök-Ur Nematodu (Meloidogyne İncognita) Üzerine Etkisi

DergiPark: 791859tujesBu çalışmada; kök-ur nematodunun, domates bitkisi üzerindeki zararının potasyumla azaltılması amaçlanmıştır. Deneme bitki yetiştirme odasında; potasyumun 4 farklı dozu (10, 20, 40, 80 mg kg-1 K) ve 2 farklı nematod durumuyla (var, yok) 4 tekerrürlü olarak tesadüf blokları deneme desenine göre kurulmuştur. Bitkiler kum kültüründe, Hoagland besin solüsyonuyla yetiştirilmiştir. Bitkinin stresten etkilenme seviyesini değerlendirmek için hasattan sonra yaprak oransal su içeriği, membran zararlanması, klorofil a, klorofil b, toplam klorofil ve karotenoid içerikleri belirlenmiştir. Denemeden elde edilen veriler MINITAB 17.0 istatistik programıyla değerlendirilmiştir.Sonuçlara göre; köklerde ki urlanmalar, 0-10 ur skalasına göre düşük potasyum dozlarında (10, 20 mg kg-1 K) yüksek potasyum dozlarına (40, 80 mg kg-1 K) göre artmıştır. Potasyum uygulamaları ölçümleri yapılan parametreleri istatistiksel olarak etkilememiştir. Nematodun her iki (evet, hayır) durumunda da, potasyum dozu arttıkça, yaprak oransal su içeriği artarken, membran zararı azalmıştır. Elde edilen sonuçlara göre potasyum uygulamasının domates bitkilerinde kök-ur nematodunun (Meloidogyne incognita) verdiği zararı hafifletebileceği söylenebilmektedir

Fire induced changes in soil characteristics in Keşan, Turkey

This research was conducted in Ke an (Çınarlıdere) area (1689 ha) of Thrace region, Turkey. The forest area was burned naturally in 2000. The aim of this research was to determine the effects of forest fire on some soil characteristics two year after the fire. Soil samples were collected from three locations as replicates from both burned and nearby unburnt sites. According to the study results, urease activity and soil organic carbon values (P<0.001), organic nitrogen and total porosity (P<0.01), aggregate stability, microbial biomass carbon values (P<0.05) were lower in burned soils than those of unburned soils. On the other hand, hydraulic conductivity and available phosphorus in unburned soil was not significantly higher than that of burned soils. This research showed negative effects of fire on some soil characteristics after two years

L’immigration turque en France et en Allemagne

Numéro consacré à ces deux communautés turques, l'une, en Allemagne, nombreuse (environ 1 600 000 personnes) et l'autre, en France, en croissance rapide (entre 200 et 250 000). Analyse comparée de leurs modes d'intégration et des problèmes qu'elles rencontrent, notamment en raison de la montée du racisme, le rôle des associations politiques et religieuses, l'évolution des envois de fonds des travailleurs immigrés.
