Climatic conditions of environmental zone Nemoral 2 of Europe are favorable for agricultural development. However, more frequent events of hot air-waves and prolonged droughts occurring as a consequence of climate change lead to soil moisture content reduction down to the plant wilting point. Dry soil conditions may have negative consequences for soil as a habitat. The goal of this study was to evaluate the cumulative after-effect of long-term conventional (CT) and no-tillage (NT) application in combination with or without crop residues on soil physicochemical properties, microbiological activity, and soil respiration (SR) under prolonged dry soil conditions. Long-term CT with residue …

Sensitivity Of Soil Evaporation And Reference Evapotranspirationto Climatic Variables In South Korea, Mehmet Aydin, Yeong-Sang Jung, Jae E. Yang, Su-Jung Kim, Kyung-Dae Kim

Turkish Journal of Agriculture and Forestry

The quantification of evapotranspiration and soil evaporation is crucial for agricultural water management. The FAO-56 Penman-Monteith and E-DiGOR models were used to compute reference evapotranspiration (Eto) and bare soil evaporation, respectively, at 17 meteorological stations of South Korea, from 1980 to 2009. The same soil parameters were assumed for all stations in order to compare actual soil evaporation (Ea) rates jointly dominated by atmospheric evaporative demand and soil water availability, as well as the size of rainfall events. The sensitivity of Penman-Monteith type equations to the major climatic variables was determined based on 1-year dataset. The long-term mean annual precipitation …

Physical And Chemical Properties Of Recently Deposited Sediments In The Reservoir Of The Borçka Dam In Artvin, Turkey, Bülent Turgut, Mehmet Özalp, Bahti̇yar Köse

Turkish Journal of Agriculture and Forestry

Large dams produce important changes in flow regime and sediment deposition and distribution in rivers. When inundation starts with the building of dams, water surface area increases, flow rate decreases, and sediment carried by the river is deposited in the reservoir. However, there is a lack of research on the physical and chemical properties of recently deposited sediment in reservoirs of large dams. We aimed to fill this gap in the literature by providing valuable data on the initial formation of sediment deposition areas in reservoirs. Therefore, the aim of this study conducted within the Borçka Dam reservoir was to …

Turkish Journal of Agriculture and Forestry

Banana (Musa spp.) is an important tropical fruit with high commercial potential. Musa balbisiana (B genome) is a progenitor of one of the most cultivated banana species and exhibits unique traits, including resistance or tolerance to many biotic and abiotic stresses. RNA sequencing of the Musa B genome would provide a vast array of transcriptomic information that could lead to the development of trait-specific markers and the discovery of new genes and regulatory sequences involved in resistance mechanisms. Thus, transcriptome sequencing was performed in Musa B genome accession Attikol using the Ion Torrent platform. This led to the generation of …

Turkish Journal of Agriculture and Forestry

The benefits of silicon (Si) in improving crop fitness by biotic and abiotic stress resistance are widely reported. However, investigations about its protective mechanisms for plants facing multiple stresses are very limited. Two contrasting rice cultivars, KS-282 (salt-tolerant) and IRRI-6 (salt-sensitive), were grown in a pot experiment to study the interrelation between Si supplementation (0 and 150 mg kg-1) and boron (B) toxicity (0 and 2.5 mg kg-1) under salinity stress with emphasis on growth response, mineral contents, physiology, and enzymatic antioxidant system response. The results revealed that adverse growth conditions, particularly the combined stress of salinity and B toxicity, …

Incidence Of Microbial Infections Revealed By Assessing Nodulation Infield-Collected Insects From Adana Province, Hasan Tunaz, Mehmet Kubi̇lay Er, Ali̇ Arda Işikber

Turkish Journal of Agriculture and Forestry

Results of a field study designed to assess the extent of natural microbial infections in insects collected from agrarian fields surrounding Adana, Turkey, are reported. We identified and dissected specimens to assess the numbers of nodules. Formation of darkened melanotic nodules is the predominant cellular immune reaction to microbial and parasitic infection, and once formed, the nodules are permanently attached to internal surfaces. At least some nodules were found in 99% of 1200 examined specimens that were healthy in appearance. The number of nodules ranged approximately from 1 nodule/individual to >120 nodules/individual. We inferred that insects are regularly challenged by …

Turkish Journal of Agriculture and Forestry

Molybdenum cofactor sulfurases (MCSUs) are important enzymes for plant development and response to environmental queues, including processes such as nitrogen metabolism and regulation of the abscisic acid levels in plant tissues. We cloned and sequenced MCSU gene from barley and performed in silico comparison with rice, tomato, and Arabidopsis. Physico-chemical properties and subcellular predictions were found to be similar in different plant species. All MCSUs had three critical domains: aminotransferase class-V (Pfam: PF00266), MOSC N-terminal beta barrel (Pfam: PF03476), and MOSC (Pfam: PF03473). Secondary structure analysis revealed that random coils were the most abundant, followed by α-helices and extended strands. …
