Wheat is widely grown in Iran as a staple food; therefore, the government there encourages farmers to produce wheat (a common agricultural enterprise) by increasing farm productivity and efficiency. The study compares the efficiency of wheat production for dryland (low input) and irrigated (high input) systems across Iranian provinces by using Data Envelopment Analysis (DEA). The average techni...

Cropcheck developed following the identification of limitations to the Transfer of Technology (TOT) extension model which occurred through the 1970’s and into the early 1980’s (Lacy 2011). Irrigated wheat yields stagnated with high variability from year to year and no understanding as to why this occurred. This was despite several communication methods (farm visits, demonstrations, plot trials,...

iranian farmers are faced with many challenges. they must be economically efficient, produce enough food for the growing population and must be sensitive to environmental concerns. however, there is a growing concern related to the aftermath and side-effect of some agricultural activities on environment. these concerns made researches to consider agricultural activities with profound care in or...

Agriculture has a key role in greenhouse gas emissions.  As such, the present study aimed to evaluate the greenhouse gas emissions from wheat production in irrigated and rain-fed systems. The primary data were collected from 116 wheat farmers. The results showed that the total greenhouse gas emissions from wheat production in irrigated and rain-fed systems were 637.8 and 65.12 kgCO2eq, respecti...

Irrigated crops are produced on 645,000 ha in east-central Washington and northcentral Oregon (1). Approximately 70% of this cropland is irrigated with water diverted from rivers, while water for the remaining hectares is pumped from deep wells. Much of the irrigated cropland is found in areas of less than 200 mm annual precipitation, where dryland farming is difficult or impossible. Wind erosi...
