Yaylacılık ülkemizde önemli bir gelenek olup, bu araştırma, 2014-2015 vejetasyon döneminde, Trabzon İli Düzköy İlçesi Yaylası (Kamema)’nın yaş ot ve botanik kompozisyonları ile birlikte florası incelenmiştir. Yayla (Kamena) çayırlarının verimleri 2.450-3.275 kg da-1 arasında değişmiş ağırlık esasına göre ise % 73 buğdaygiller + 12 baklagiller 15 diğer familyalardan oluşmuştur. Yapılan floristik...

unshaded sites in southern USA when exposed to high summer temperatures (Van Santen and Sleper, 1996). The design of agroforestry systems requires a thorough understandNeither orchardgrass nor tall fescue had significant ing of biological interactions that might complement or constrain yield reduction in pots exposed to 50% shade, and orproduction. The objective of this study was to examine eff...

Although cool-season grasses increase DM yield at high N rates, N recovery (kg plant N kg 1 N applied) Nitrogen removal by cool-season grasses may aid in capturing exgenerally declines as N rate increases. Ramage et al. cess N from animal confinement operations or phytoremediation. (1958) reported fertilizer N recovery of 0.59 and 0.59 kg Limited information exists on the N dynamics of these gr...

Aphids feed on plant phloem sap, rich in sugars but poor in essential amino acids. However, sugars cause osmotic regulation problems for aphids, which they overcome by hydrolysing the sugars in their gut and polymerising the hydrolysis products into oligosaccharides, excreted with honeydew. Aphids harbour primary bacterial endosymbionts, which supply them with essential amino acids necessary fo...

Agricultural practices, including tillage, fertilization, and residue management, can affect surface runoff, soil erosion, and nutrient cycling. These processes, in turn, may adversely affect (1) quality of aquatic resources as habitat for amphibians, fish, and invertebrates, (2) costs of treating surface and ground water to meet drinking water standards, and (3) large-scale biogeochemistry. Th...

Arabinogalactan-proteins (AGPs) are widely distributed in higher plants and play multiple roles in various processes associated with plant growth and development, including cell expansion, cell proliferation and embryogenesis. Soluble extracellular AGPs are also abundant in the growth medium of suspension. Levels of cell wall bound and extracellular AGPs were measured spectrophotometrically usi...

Since grass will likely be a dominant feedstock for on-farm anaerobic digestion in Northwest Europe, changes in the chemical composition of five common grass species with advancing harvest date in the primary growth were investigated and related to specific CH(4) yields. The increase in fibre components with advancing harvest date had a negative impact on the specific CH(4) yield (253 and 225 N...
