تحديد المساحة المثلى للقمح باستخدام الري بالرش

Abstract EN

The aim of the research is to study the nature of wheat production cost in Saladhin province by using sprinkler irrigation and comparing it with gravity irrigation.

From costs data costs function could be estimated in order to derive optimum area of wheat by using sprinkler irrigation and comparing it with the optimum area of the crop by using traditional irrigation.

This research depended on data derived from stratified random sample for wheat farmers in Saladhin province for the production season 2001-2002.

The sample included 223 farmers using traditional irrigation representing 77% of the total population and 65 farmers using sprinkler irrigation representing 23% of the total population which amounted to 288 farmers.

The results showed that 63.27% of farm labour in the province depended on family labour before harvesting while this percentage decreased during and after harvesting to about 36.73%.

The hired labour employed before harvesting formed 27.66% and during and after harvesting formed 72.34% of total labour.

The results of gravity irrigation for IPA cultivar that the optimum area is 39.5 hectares while the percentage of the cultivar farms while achieved economies of scale were 79%.

The results of sprinkler irrigation for the same cultivar showed that the optimum area was 36.5 hectares while the percentage of the cultivar farms which achieved economies of scale were 88%.

The results also showed that the economic efficiency of the sprinkler irrigation farmers was better than the gravity irrigation farmers as the IPA cultivar using sprinkler irrigation a level of economic efficiency of 89% of total farms, while it achieved on economic efficiency of 64% in gravity.
