Social development is possible with agriculture. With the impact of environmental pollution, natural disasters, climate change, food security, and population growth, interdisciplinary "new agriculture" is becoming an important trend of modern agriculture. Hydrogen (H2) is the most common element on earth, making up more than 75% of the mass of the universe. Hydrogen gas is colorless, odorless, and tasteless and is considered a physiologically inert molecule and a potential source for clean energy in the future. Hydrogenated agriculture including mainly hydrogen-rich water (HRW) focuses on the molecular mechanisms underlying improved agricultural product quality. Studies have shown that H2 does not only affect plant growth and development but also affects the nutritional quality and shelf life of the fruit. Hydrogenated agriculture emerges as a promising technology for the sustainability of agricultural products in modern agricultural practices thanks to the different beneficial effects of H2 such as safety, nutritional and antioxidative properties, and high product productivity. In this review, the roles of H2 in plants, seed germination, seedling growth, root development, stomatal opening and closing, pre-harvest freshness, post-harvest freshness, and the changes caused by hydrogenated agriculture at various stages of the plant such as anthocyanin synthesis have been investigated.

In the study, the growth performances of the Shibot fish (Tor grypus) with an average weight of 2.38 g were evaluated by feeding them with 3 different protein-containing feeds for 45 days. In order to create these evaluations, the experimental groups were designed as G1 (33%), G2 (37%) and G3 (41%) fed with different protein levels. Effects on body weight gain (BWG), Feed conversion rate (FCR), Specific growth rate (SGR), Survival rate, Economic conversion rate (ECR) and Economic profit index (EPI) as growth parameters has been researched. At the end of the study, the offspring reached a weight of 3.42±0.16 g, 4.17±0.06 g and 4.50±0.02 g, respectively. G3 and G2 group individuals showed similar performance in terms of end-trial FCR, EPI and ECR.

Peppermint is one of the valuable medicinal and aromatic plants with its powerful flavour and fragrance. Its leaf and essential oil are used in cosmeceuticals, foods, pharmaceutical and personal care products. It is well known that yield and secondary metabolite biosynthesis in the medicinal and aromatic plants are strongly influenced by abiotic stresses. Salinity is also one of the most important stress factors affecting plants. This study was carried out to determine the effect of salt stress on growth, essential oil content and oil constituents in peppermint plants. For this aim, three different concentrations of sodium chloride NaCl (0, 100 and 150 mM) were applied to peppermint plants. As a result of the study it was determined that all of the investigated parameters were significantly affected by NaCl applications. Shoot length, fresh and dry weights of plants and essential oil content decreased in line with the elevating level of NaCl. Besides, NaCl also caused differences in essential oil composition. Menthol and menthone, the main components of the peppermint oil, reduced significantly when NaCl concentration rose to 150 mM. Based on the results, it may be concluded that NaCl especially at high concentrations considerably and negatively affected plant growth, essential oil content and quality of the essential oil.

The aim of this study was to determine the growth parameters of European Flounder fry (Platichthys flesus luscus L. 1758) caught from the nature in different feeding methods in aquaculture conditions. The study was conducted between April and July 2011, and the fish were collected at the connection point of Sarıkum Lagoon with the Black Sea in Sinop Province using seines and large scoops. A total of 750 European Flounder with the average weight of 0.93±0.01 (0.71-1.21) g were stocked in 5 groups with 3 repetitions. The groups were organized according to the feeding protocols [G1:90 days Chironomid larvae (CL), G2:60 days CL+30 days CL+ granular feed (GY), G3:30 days CL+60 days CL+ GY, G4:90 days CL+GY, G5:90 days GY]. At the end of the study, the weights of the fish were determined as 10.83±0.51, 9.89±0.22, 6.33±0.21, 5.13±0.11, 3.81±0.09, respectively. It was found that feeding preferences of the fish had significant effects on weight gain, specific growth rate, feed conversion ratio and survival rate. European Flounder fry, as in their natural habitat, mostly preferred natural feed moving in the deep in the production site. It was determined that using live feed as the starter feed for the adaptation of European Flounder fry had a significant effect on growth parameters and survival rates.

Uniform description of developmental stages in crops improve communication among producers, researchers and others. A standardized, accurate, and easy system is needed to describe bean (Phaseolus vulgaris L.) plant development. The objective of this study was to develop and describe stages of bean plant development in a manner which is simple but accurate. The biological cycle of the bean plant is divided into two successive phases: the vegetative stage (V) and the reproductive stage (R). Vegetative stages are determined by counting the number of trifoliolate leaves (V1 to VN) on the main stem beginning above the unifoliate leaf. Reproductive stages R1 and R2 are based on flowering, R3 and R4 on pod development, R5 and R6 on seed development, and R7, R8 and R9 on maturation.

This study was aimed to determine the effects of 24-eBL, a steroid growth regulator, on the plant growth, total phenolic content, essential oil content and composition in “Munstead” lavender cultivar belonging to Lavandula angustifolia. For this aim, 24-eBL was applied to plants at four different concentrations (0, 0.75, 1.50 and 2.25 mg/l) twice, at the beginning of budding and 10 days after the first application. The plants harvested during the full bloom period were evaluated for fresh and dry stemmed flower yields, stemless dry flower yield, total phenolic content and essential oil yield and composition. As a result of the study, 24-eBL at concentrations of 0.75 and 1.50 mg/l significantly increased the stemless dry flower yield, total phenolic content and essential oil yield per plant. 24-eBL applications also changed essential oil composition. To conclude, 24-eBL applications can be used to increase the dry flower yield, phenolic and essential oil contents in lavender plants.
