Chemical phosphorus and other chemical fertilizers undergo certain changes in the soil. These changes cause crop yield loss because of changes in soil pH and EC. In addition, other toxic compounds accumulate. They also lead to serious soil contamination and threaten the environment. In this study, vermicompost was developed from raw phosphate rock by using microorganisms and phosphorus solubilizing enzymes (protease, lipase, dehydroge & PRIME;nase, hydrolase, urea, nitrogenesis, cellulose) to eliminate phosphorus deficiency in soil. Two-year greenhouse trials were conducted to determine the effectiveness of the organic phosphorus humus produced after six months of mineralization, and tomato plants were grown. As a result of these experiments, the effects on yield and physicochemical properties of the tomato plant were studied. Earthworm fertilizer at a rate of 4500 kg ha-1 increased the tomato yield of 22.12% compared to the control application, in the two-years means. In addition, the effect on nutrient content of tomato plants resulted in statistically significant increases (p < 0.05). When the macronutrient concentrations in the leaves of the plant were examined, they were considered to have reached the level of sufficiency. It was also found that the content of amino acids, chlorophyll and antioxidants in the tomato plant reached the highest levels compared to the control application. Based on our results, it was concluded that this organic fertilizer will contribute to higher crop yields in plants of cultural and commercial importance and to other plant growth parameters.

For the first time in the world, raw tea waste from tea plants was mineralized by rapid biotechnological methods using beneficial worms, enzymes (protease, lipase, dehydrogenase, hydrolase, urease, nitrogenase, cellulase) and microorganisms (Aspergillus flavus, Bifidobacterium spp. Bacillus subtilis, Rhodotorula spp., Lactobacillus, Rhodopseudomas spp.). Thus, biocompost technology was developed to create an exclusive organic tea fertilizer. The biocompost product was developed in a plant-friendly format for sustainable use of local resources. It was rich in organic material and free from diseases and pathogens, according to organic farming methods. It was also reliable in terms of heavy metal content. In the biocompost study, the application of five different compost mixtures and three different application methods were investigated. Worm + Plant Growth-Promoting Rhizobacteria + enzymes accelerated the mineralization of the compost among the studies, and the lowest C/N and OM % ratio was obtained. The other physical and chemical parameters were also in accordance with the ideal values determined in the literature. Also, the increase of nitrogen without nitrogen loss during the composting process shows that mineralization was successfully completed. In concluded, it can be suggested that the developed organic worm compost fertilizer can be used on agricultural land and in regenerative agriculture.

The aim of this study was to determine the effects of single and combined applications of plant-growth-promoting rhizobacteria (PGPR) bacteria on plant nutrition, biochemical content and fruit characteristics in Albion and Monterey strawberry cultivars. Bacillus subtilis OSU-142, Bacillus megaterium M3 and Paenibacillus polymyx were the PGPR used in the experiment. For each bacterial treatment, 10 mL of a 108 CFU mL-1 suspension was applied to the soil where Albion and Monterey cultivars were grown. PGPR bacteria were applied as single treatments and a mixture of equal amounts of these three bacterial species was applied as a mixed treatment. This study was carried out with a total of four different bacterial treatments and one control group. The highest fruit weight was obtained in the Monterey cultivar with 12.67 g in the Mix treatment and in the Albion cultivar with 11.79 g in the Bacillus megaterium M3 treatment. Regarding biochemical properties, Paenibacillus polymyxa was effective in influencing nutrient element content in fruits, while Bacillus subtilis OSU-142, Paenibacillus polymyxa and Bacillus megaterium M3 applications were more effective in leaf nutrient element content. It has been observed that the Mix treatment resulting from the combined use of bacteria, rather than their separate use, has a greater impact on fruit weight. Consequently, it has been understood that PGPR bacteria are potentially effective in improving the agronomic, pomological, and biochemical characteristics of strawberry cultivars and can be used in studies and breeding programs aimed at increasing strawberry yield and quality.

Deficiency of Boron (B) is widespread in the many parts of region of Turkey. So, the effects of boron and plant growth promoting bacteria (Bio-B) on the fruit yield, antioxidant enzyme activity and plant freeze injury of strawberry cv. Fern were investigated under field conditions between 2013 and 2014. The experimental plot was a completely randomized design with 4 replicates. Control and Bio-B were used as fertilizer agent in the experiment. Bio-B fertilizer was applied in three methods as soil, foliar and soil + foliar application methods to strawberry plants. Data through 2 years showed that the use of Bio-B significantly increased fruit yield, antioxidant enzyme activity and decreased freeze injury of strawberry leaf. Soil + foliar applications of Bio-B fertilizer increased to fruit yield compared to the control by 55.91 %. However, foliar application of Bio-B fertilizer increased to catalase (CAT), peroxidase (POD), and superoxide dismutase (SOD) enzyme activity compared with the control treatment 41.86 %, 48.99 %, and 26.59 %, respectively and decreased freeze injury of strawberry leaves 27.41 %. Overall, the results of this study suggest that Bio-B fertilizer application have the potential to increase the yield, antioxidant enzyme activity and decreased freeze injury of strawberry plants under field conditions.

(Parlar Scientific Publications (p S P), 2019) Horuz, Ayhan; Turan, Metin; Akinoglu, Guney; Ozcan, Cengiz; Gunes, Adem; Korkmaz, Ahmet; Ozlu, Ekrem
The transformation of agro-industrial wastes into value-added commodity is among the best approches to a greener and more sustainable future. The aim of in this study was to examine the effects of phosphogypsum waste (PGW) as fertilizer to improve yield and nutrient content in the grain, stem and leaves of corn (Zea mays L.). A randomized experiment via a complete plot design was applied using four different triplicated doses of PGW (0, 1, 5 and 10 tons ha(-1)). It was shown that improvement in corn yield was proportional to the increase in PGW dose, corresponding to 46.19%, 38.76% and 39.65% for 1, 5, and 10 ton ha(-1) of PGW, respectively. A 5.85 ton ha(-1) PGW dose was optimal in yielding a 8.63 ton ha(-1) of corn despite a 8.26 ton ha(-1) the production yield using 5 ton ha(-1) PGW, as the latter was statistically borderline significant. The approach adopted here also yielded corns with higher macro- and micronutrient contents compared to the control. The analysis of variance data illustrated that the improved contents of N, P, K, Ca, Zn and B per 1 ton ha(-1), and Mg per 5 ton he were also significant (P<0.05). It can be construed that the recommended dose of PGW as fertilizer between 1-5 tons ha(-1) can lead to substantial improvements in yield and nutrient contents in corn.

Lichens contain a sufficient amount of plant nutrients for plant growth. Studies have shown that the characteristic secondary metabolites they produce contain significant amounts of organic acids, amino acids, and hormones. This study aims to examine the effects of 10 different lichen species Aspicilia calcarea (A. calcarea), Cetraria islandica (C. islandica), Cladonia furcate (C. furcate), Flavoparmelia caperata (F. caperata), Lobaria pulmonaria (L. pulmonaria), Pseudevernia furfuracea (P. furfuracea), Rhizoplaca chrsoleuca (R. chrsoleuca), Umbilicaria vellea (U. vellaa), Xanthoparmelia somloensis (X. somloensis), Usnea longissima (U. longissima) on metabolic properties and growth parameters of maize plant for possible use as a plant food source in sustainable and organic agriculture. As a result of the research, it was observed that when lichen species were applied as plant nutrients, there were significant increases in plant height, plant weight, dry matter ratio, some nutrient content and amino acid levels of maize compared to the control group. Among the treatments, Lobaria pulmonaria application at 5 g/kg resulted in the highest values for plant height (145.00 cm), plant weight (187.00 g), and dry matter ratio (19.21%). The research shows that different lichen species significantly affect the amino acid content, nutrient content, and growth parameters of the maize plant at various levels.

(Bmc, 2024) Gurcan, Kahraman; Yilmaz, Kadir Ugurtan; Tunc, Yazgan; Yaman, Mehmet; Gunes, Adem; Yildiz, Ercan; Khadivi, Ali
BackgroundGenetic diversity is a prerequisite for breeding programs, and one of the main goals here is to obtain quality products. Therefore, this study aims to evaluate the genetic diversity in some hybrid individuals of honeyberry (Lonicera caerulea L.) based on fruit characteristics, leaf morphology, vitamin C, antioxidant activity, biochemical, and nutritional content. In this context, superior quality individuals have been identified based on the 42 variables examined in our study. These hybrid individuals can be economically incorporated into production after the registration stages, and their sustainability for use in breeding programs can also be ensured.ResultsThe fruit weight ranged from 0.71 ('H11') to 1.66 g ('H6'). The ascorbic acid varied between 17.13 ('H7') and 20.64 mg AAE/100 g ('H15'). The antioxidant activity changed between 12.59 ('Store') and 15.03 mu mol Trolox g-1 ('Aurea'). The total anthocyanins were found to be highest in 'Borrel Beast' (163.79 mg cyn-3-gluc 100 g-1), followed by 'H8' (163.20 mg cyn-3-gluc 100 g-1). The highest nutrient levels in the fruits were found in the 'H10' individual, with calcium (2445.77 mg kg-1), potassium (2274.36 mg kg-1), phosphorus (2123.27 mg kg-1), magnesium (1263.95 mg kg-1), and sulfur (859.62 mg kg-1), respectively. The highest nutrient levels in the leaves were found in the 'H14' individual for calcium (19,493.21 mg kg-1), 'H5' for magnesium (5643.52 mg kg-1), 'H8' for sulfur (2312.11 mg kg-1), 'H6' for phosphorus (2007.51 mg kg-1), and 'H6' for potassium (1099.32 mg kg-1). In general, the nutrients in the fruit exhibited significant correlations among themselves at different levels (*, **, ***). Within the scope of principal component analysis, the first 8 principal components explained 80.69% of the total variance. According to the cluster and population analyses, it was determined that there was a high variation in subgroup B2. Additionally, although honeyberry is a relatively new fruit in T & uuml;rkiye, efforts have begun to develop new cultivars through hybrid breeding.ConclusionsWhen 42 variables were evaluated together to determine genetic diversity, hybrid individuals 'H14', 'H5', 'H8', and 'H1' were identified as superior individuals, respectively.
