Government intervention in agriculture is reflected in the persistence of state orders for the two main cash crops, cotton and wheat. Farmers receive binding directives on the area to be cropped to these commodities and are obliged to surrender their harvest to designated marketers at state-fixed prices. The incomes of farmers and agricultural workers are substantially lower than the national average because the government pays them less than the world prices for their cotton and wheat, using the difference to subsidize capital intensive industrial concerns, such as factories producing automobiles, airplanes, and tractors. Consequently, many farmers focus on production of fruits and vegetables on their small household plots, because the prices of these commodities are determined by supply and demand, not by government decrees. Farmers also resort to smuggling cotton and especially wheat across the border with Kazakhstan and Kyrgyzstan in order to obtain higher prices.
