Abstract

In order to optimize irrigation water use in a sustainable agriculture different approaches are implemented. One of these methods is based upon the water extraction from soil. This methos is applicable if the amount of water needed by plant is measured by lysimeter or calculated by real time climatic data. In order to compare the differences between using 1- on farm real time data, 2- real time data from a climatic station outside and far from the field, and 3- using average data of meteorological data of the region an experiment was conducted on fodder CORN crop in Karaj. Farms of cron were selected close to each other and were irrigated by similar centerpivots. In one the systems sencors were placed and meteorological parametes were measured. The system itself calculated evapotranspiration durin one cycle and replaced the same amount of water which has been evaporated. In other system this action was manually don by daily meteorological data of Karaj climatic station. The third farm was irrigated based on regional average data of meteorological station of Karaj. The results showed that in first trial 6838 cubic meter of water was used and and 78 tons.ha of CORNwas harvested. Therefore water applicatioc was 11.4 kg/mÙ3. The results for second and third trial were 7640, 78.2, 10.2 and 9350, 79.9, 8.5, respectively. This showed that if real time and on farm data of meteorological parametes are used for calcuilating irrigatin needs, yield could be increased by 27 percent.
