Effects Of Wheel Traffic Porosity And Compaction Of Soil Profile, Cevdet Şeker, A. Ali̇ Işildar Jan 2000

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 Jan 2000

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.

Adaptation And Stability Analysis In Some Bread Wheat Genotypes, Şevket Meti̇n Kara

Turkish Journal of Agriculture and Forestry

Genotype x environment interaction is a challenging issue to plant breeders in improving high-yielding, stable genotypes for variable environments. Several methods of measuring stability of genotypes tested across a range of environments have been proposed. The grain yields of fifteen bread wheat ( Triticum aestivumL.) genotypes grown at eight different locations were used to assess adaptation and stability characteristics of the genotypes and to study associations among these parameters. According to most of the parameters used in the present study, Kiraç 66, Es-kbvd-15 and Ank-92-1 appeared to have a good level of general adaptation to all environments. Mean yield was …
