Turkish Journal of Agriculture and Forestry
The most beneficial and appropriate method for sludge resulting from food industry waste water treatment is composting with various kinds of bulking agents. During composting, the organic material in the sludge is degraded to a humus-like material that makes an excellent soil conditioner. In this investigation, sludge from yeast manifactured in the Pakmaya-D.zce Plant was composted with peat moss and corn stalk chips and used as plant growing media in containers. According to the results obtained from the investigation; 2 parts composted corn stalk chips with sludge + 1 part sandy loam soil and 20 % agricultural perlite mixture gave …

Effects Of Wheel Traffic Porosity And Compaction Of Soil Profile, Cevdet Şeker, A. Ali̇ Işildar
Turkish Journal of Agriculture and Forestry
The aim of this experimental study was to determine the effect on soil porosity and compaction of the number of the tractor passes on the soil surface. The soil has a sandy loam texture. A tractor passed once, twice, and four times while the water content of soil was near field capacity. Numbers of tractings increased soil bulk density and compaction, and decreased total porosity, void ratio, air porosity and drainage porosity. One and two tractor passes did not markedly affect the percentage of porosity kept at field capacity porosity, but four tractor passes improved it.

Herbicide-Induced Resistance To Fusarium Wilt In Cotton And Gossypol Production Of Host Cells, Yeter Canihoş, Şener Kurt, Hülya Özgönen
Herbicide-Induced Resistance To Fusarium Wilt In Cotton And Gossypol Production Of Host Cells, Yeter Canihoş, Şener Kurt, Hülya Özgönen
Turkish Journal of Agriculture and Forestry
Pretreating cotton seeds with some herbicidies used in cotton-growing areas of the Çukurova region markedly increased cotton resistance to Fusarium wilt caused by Fusarium oxysporum f. sp. vasinfectum. Haloxyfob and linuron reduced the mycelial growth of the pathogen in both solid and liquid cultures. However, prometryn was more effective in plant development than linuron and haloxyfob. Synthesis of Phytoalexin gossypol was significantly produced in inoculated cotton plants compared with uninoculated control plants. Maximum amounts of gossypol production were obtained in herbicide-treated and inoculated cotton plants. Gossypol extracted from herbicide-treated plants markedly reduced the mycelial growth of the pathogen in vitro.
