SESSIZ, A., A. ALP and S. GURSOY, 2010. Conservation and conventional tillage methods on selected soil physical properties and corn (Zea mays L.) yield and quality under croppin system in Turkey. Bulg. J. Agric. Sci., 16: 597-608
This study was conducted to determine the effects of conventional and conservation tillage on the some soil physical properties, penetration resistance (PR), seedling emergence rate, yield and yield components under southestern of Turkey conditions. The experiments were carried out at 2003 and 2004 years in a clay loam soil. Six different soil tillage methods in corn production were tested. The experiment was performed in randomized block design with six treatments and each treatment consists of three replications. No significant (p>0.05) treatment differences in seedling emergence were found between the tillage treatments for both years. Plant height was found significant between years while treatment effects were not significant. However, the highest plant height was obtained in 2004 under CT tillage method. The stalk thickness was found significant between years while treatment effects were not significant. The cob length was not found significant between years and treatments. The lowest cob length was obtained under NT method. It was found that yield was significantly (p<0.01) different between years. The yield in the second year was found to be higher than that of the first year. The highest yield was found in CT method as 678.00 kg/da and the lowest yield was found in RT4 method as 535.66 kg/ha in year 2003. The highest yield was found in CT method as 778.66 kg/da and the lowest yield was found in RT4 method as 642.33 kg/ha in year 2004. The highest fuel comsumption was obsorved as 33.48 Lha-1 in conventional method (CT) whereas the lowest value was found in direct seeding method as 6.6 Lha-1.
