Özet

Turkey has an important potential by means of wheat production in the world. Wheat has intensively grown in Central Anatolia which has supported approximately half of wheat production in Turkey for ages. In this research, to estimate the effect of herbicide usage in non-irrigated and irrigated wheat production, a random sample of 152 farmers in the Central Anatolia Region was interviewed in 2004/2005 periods. Farms had averagely 7.49 ha of non-irrigated and 5.46 ha irrigated wheat production land. Herbicide used during wheat production was meanly 1,027.5 g per hectare under non-irrigated conditions and 1,339.2 g per hectare under irrigated conditions. The herbicides are responsible for 2.3-2.8 % of production cost in wheat production. In this paper, a simple relationship between a farm-level wheat output-and farm inputs was searched on collected data from farms in Central Anatolia by using a Cobb-Douglas production function. The models were statistically significant at the 69.0-70.0 % confidence level. It was determined that there were satisfactory effects of fertilizer and herbicide on wheat productivity for non-irrigated conditions and besides of them and also the size of wheat area and machinery equipments for irrigated conditions. The output elasticity of inputs was less than 1. © Eugen Ulmer KG.
