Kazova Yöresinde Buğday-Ayçiçeği Münavebesinde Farklı Toprak İşleme Yöntemlerini

Tillage methods of according to climate characteristics of Tokat province Kazova region which located passage climate zone have been made an economical comparision in wheat-sunflower rotations. The study was carried out with 3 replications in randomized block strial design between 2011 and 2014 in Middle Black Sea Transitional Zone Agricultural ResearchInstitute. This study soi ltillage as method; T1: Plow + discharrow + bowed cultivator + seeder, T2: Chisel + discharrow + seeder, T3: Rototiller + seederand, T4: The direct seeding. As a result of the economic analysis, the traditional tillage method in the sun flower and the direct seeding method in wheat have been the most profitable methods. Gross profit in wheat was found to be 957.78 TL ha -1 for T4 as highest and 743.31 TL ha -1 for T1 as lowest. The highest gross profit in the sunflower was obtaiened 1 411.16 TL ha -1 for T1 and the lowest gross profit 1 013.46 TL ha -1 for T4 (direct planting). The direct seeding method is the late strow as gross profit in the sunflower. Indirect sowing method, the use of herbicide due to weed problem increased the input cost and reduced the yield. The method will be more profitable when the weed problem is solved indirect seeding. At result of this study, it can be seen that can be used direct planting in the wheat and reduced tillage systems in the sunflower as suitable method due to labor and energy decreases when the field traffic decreases.
