    Effect of Plant Growth Promoting Rhizobacteria on Growth, Nutrient Uptake and Physiological Parameters in Sugar Beet under Different Irrigation Levels
    (2020) Çakmakçı, Ramazan; Karagöz, Halit
    Two experiments were conducted to investigate the of nine ACC deaminase-containing, IAAproducing, N2-fixing and/or P-solubilizing bacteria, on the growth, yield, chlorophyll, macro- and micro-nutrientcontent, and selected morpho-physiological parameters of sugar beet, under five irrigation levels (150%, 100%,75%, 50%, and 25% of water-holding capacity). The research was established according to factorial arrangementin randomized block experimental design of five water regimes, eleven treatments and five replications. Theexperiment was set up in two sets; and the first set was harvested after 65 days and the second set was done after130 days. Inoculation with multi-traits bacteria stimulated overall plant growth, including sugar content, root andleaf yield and the leaf chlorophyll contents, and macro- and micro-nutrient uptake, which might partly contributeto the activation of the processes involved in the alleviation of the effect of water stress. According to the results,under water constraint at the level of 75, 50 and 25% of water-holding capacity, beet yield parameters BF4, BF6,Bio-organic and mineral fertilizer was found effective. As an average of the five water regimes, bacterialformulations increased dry storage root weight by 6.5-27.7% and 9.1-27.3% and dry leaf weight by 6.1-26.7%and 3.9-25.8% at the first and second trials, whereas, mineral fertilizers (NP) and bio-organic fertilizersincreased dry storage root weight by 24.5% and 9.3-15.5% and 20.2 and 9.2-15.2%, and dry leaf weight by23.5% and 11.7-23.2% and 22.2% and 3.3-21.9%, respectively, compared with control. Moreover, water stressin sugar beet plants was alleviated partially by the inoculation with bacterial strains. Our results provide strongevidence that the role of bacteria in the performance of sugar beet plants in the stressful environment of soils notonly the improved plant growth, yield, and macro- and micro-nutrient content, but also the alleviation of waterdeficit and waterlogging stress.

    Flavor in a Tea Glass to Present from Past: Safely Organic Production and Health Effects of Tea
    (2021) Karagöz, Halit; Erduran, Erdim; Çakmakçı, Ramazan; Karagöz, Fazilet Parlakova
    Tea (Camellia sinensis (L.) O. Kuntze) is the second most-consumed non-alcoholic beverage in the\rworld after water. The health-beneficial properties of tea, known to contain more than 4000\rbioactive substances, of which about one-third consist of polyphenols, are increasingly well\runderstood. The medicinal properties of the tea plant have been proven by laboratory and clinical\rstudies to have an anti-cancer effect, benefits for dental health, protect against Alzheimer with antiparalytic, anti-diabetic, and antiparkinson properties, and its use against skin diseases. However, it\ris known that the tea plant, which requires plenty of fertilizer, can cause excessive pollution of the\rgroundwater when chemical fertilizers are washed away with precipitation in the areas where it is\rgrown. In order to eliminate this negative situation, studies regarding organic and microbial\rfertilizers that are more environmentally friendly and do not harm the soil and human health that\rcould be substituted for chemical fertilizers as much as possible or mitigate their use and enable to\rgrow products of adequate amount and quality should be accelerated. The aim of this review is to\rbring together scientific information about the characteristics and health effects of tea and organic\rtea cultivation
