“…Calcium binding to cell wall components may also reduce the accessibility of cell wall degrading enzymes to their substrates [Vicente et al 2009] and by this way storage and shelf life of fruits can be enhanced. Preharvest calcium sprays are one of the most important practices of the new strategies applied in the Integrated Fruit Production systems [Manganaris et al 2005], improving fruit characteristics and minimizing fungicide sprays towards the end of the harvest period [Sabir et al 2014], since they enhance fruit resistance to brown rot [Conway et al 1994]. Sprays with calcium chloride based formulas are extensively used [Manganaris et al 2005], whereas micronized calcium sources are promoted as alternative sources, characterized by a high absorption capacity [Sabir et al 2012].…”

Demand for fresh grape is increasing globally in accordance with the improvement in living standard since the grape berry contains large amounts of phytochemicals including anthocyanins, phenolics, flavonoids and resveratrol, which have been suggested to be responsible for human health benefits. However, table grapes easily undergo deterioration due to their soft texture and the high water content, which make it difficult to preserve without treatment. This study was thus conducted to evaluate the effect of preharvest calcium sprays on maintenance of postharvest quality of grapes (V. vinifera L. cv. 'Thompson Seedless'). Three preharvest calcium sprays were applied to leaves and developing green berries with or without leaf removal pruning (a traditional practice performed in commercial vineyards worldwide) during berry development stages. After harvest, grapes were cold stored (1°C, 90% R.H.) up to 3 months. Preharvest micronized calcium sprays, with or without leaf removal pruning, markedly extended the postharvest quality of grapes by delaying weight loss, reducing decay, maintaining rachis chlorophyll concentrations and preserving visual quality during the prolonged cold storage. Besides, in calcite-treated grapes, lower titratable acidity decrease courses with a subsequent lower maturity index during prolonged storage indicate that calcite sprays restricted postharvest physiological senescence of grapes. Overall findings indicated that preharvest calcite sprays may be an environmental-friendly, healthy and sustainable viticulture practice for extending postharvest quality of grapes.

“…Rajarajan et al (2014), has stated that seaweed treatments cause to increase in the amount of photosynthetic pigments in plants and Mohamed and ElSehrawy (2013) has claimed that even low doses seaweed treatments can provide high chlorophyll production. It is claimed that this increase in the amount of chlorophyll is caused by the reduction in the degradation of chlorophyll and this is because of betaine found in the seaweed (Sabır et al, 2014;Shahbazi et al, 2015).…”

“…They are valuable organic fertilizer sources because they include growth-promoting hormones such as indole acetic acid, indole butyric acid, cytokinin, auxin and abscisic acid, trace elements (Fe, Cu, Zn, Co, Mo, Mn, Ni), vitamins and amino acids (Sharma et al, 2012;Latique et al, 2013;Peinado et al, 2014;Shahbazi et al, 2015). Many researches have claimed that seaweeds have resistance to bad environment conditions and have effects of enlarging of plant and nutrient uptake and increasing fertility (Arthur et al, 2013;Zamani et al, 2013;Rajarajan et al, 2014;Sabır et al, 2014).…”

This research was conducted to determine the effects of different seaweed doses on yield and nutritional values of hydroponic wheatgrass (Triticum aestivum L.) juice in the climatization chamber of Karabuk University, Eskipazar Vocational School, Department of Crop and Animal Production between the dates of 15. 01.2015 and 15.06.2015. In the research, four different seaweed doses (Control; 0, D1; 150, D2; 300, D3; 450 and D4; 600 ppm) and control were applied to irrigation water and their effects on the content of biomass rate, biomass and grass yield, grass juice yield and pH, plant height and root length, biomass and grass dry matter rate, grass juice energy and macronutrient values (protein, carbohydrate, fat, dietary fiber and ash) were analysed. According to the results, while the highest biomass and grass yield, plant height values were obtained from D1, D2, D3 and D4 treatments, the highest grass juice yield and root length were obtained from D3 treatment. The highest pH, grass dry matter content was obtained from control treatment. Seaweed dose treatments were not had influence on grass juice energy values. However, the rise in the grass juice yield was caused a rise in the total energy values in the unit area. D3 treatments can be recommendable to achieve the highest grass juice yield.

“…Sabir et al (2014) indicated that application of the nano Cabased fertilizer led to a significant increase in foliar development and chlorophyll concentration of the vines. In Moghaddasi et al (2013) experiments, Zn nanoparticles were produced from ground rubber and they were more effective than Zn-sulphate for cucumber.…”

Applications of biological agents intensify the growth of crops, so they more quickly form a maximum leaf area, optimize photosynthesis, increase plant productivity and quality. Chemical producers offer a new generation of bio-organic fertilizers based on nano technologies. Such fertilizers have not been well investigated yet; therefore, the aim of this study was to ascertain the influence of the fertilization rates by bio-organic nano fertilizer, made from cattle manure on the effectiveness of sugar beet crop photosynthesis and productivity parameters. The investigations were carried out in 2011-2012 at Aleksandras Stulginskis University's Research Station, Kaunas district, Lithuania (54º52′ N, 23º49′ E) on a silty loam Luvisol (Calcari-Epihypogleyic Luvisol, LVg-p-w-cc). Sugar beet plants were sprayed with the fertilizer at doses of 0.5 or 1.0 L ha -1 at the BBCH 18 and/or BBCH 31 stages. Single application of the bio-organic fertilizer at single 1 L ha -1 dose was more effective than at single 0.5 L ha -1 or double 0.5 + 0.5 L ha -1 doses. At the beginning of intensive sugar beet development (BBCH 37-38), single 1 L hadose increased the number of leaves by 19.6%, leaf area by 13.4%, root diameter by 11.1%, canopy dry biomass by 29.1%, root biomass by 42.6%, net photosynthetic productivity by 15.8%, root yield by 12.6%, sucrose content by 1.03 percentage points and yield of white sugar by 19.2% in comparison with the untreated beets. Double 1 + 1 L ha -1 dose of fertilizer was slightly more effective but economically less suitable than single (1 L ha -1 ). In general, the application of bio-organic fertilizer revealed a great potential for optimization of sugar beet development, productivity and quality parameters.
