Title

EFFECT OF IRRIGATION METHODS ON YIELD AND AGRONOMIC CHARACTERISTICS OF LONG-DAYS ONION CULTIVARS

Pages

  251-259

Abstract

 In order to study the effect of three IRRIGATION METHODS (drip, and furrow and basin) on four CULTIVARS of edible ONION long-days, during an experiment was carried out in Neyshabur Agricultural Research Station for two years (2004 and 2005). The main-plots were three methods of irrigation and the sub-plots were four CULTIVARS of ONION (red, Azarshahr Kashan white, red and white Neyshabour). That thay were studied in the strip-plot design based on the randomized complete block with three replications, and means of results based on a Duncan multiple range tests were evaluated. The results showed that, the percentage of seeds what were green in drip irrigation method was better than other methods of irrigation. The basin irrigation method had the lowest percentage of green product, but the percentage of green CULTIVARS was no significant difference. In three methods of irrigation, change the ratio of length to width of bulb was similar to others and during the growing season, with a ratio decreased to approximately. The number of multifetal ONIONs in the basin irrigation method had a significant increase to other methods of irrigation and drip irrigation method had the lowest number of multifetal ONIONs. In different methods of irrigation and CULTIVARS, thickness of ONION bulb was significant differences with each other and in drip irrigation method, the thickness of the layers of union bulb increased. In basin irrigation, ONIONs had lowest thichness of layer. In the Study of interactions, the yield of Kashan white variety in furrow irrigation to basin irrigation method increased about 47%. And the average yield of white Kashan variety, in drip irrigation was 30% more than basin irrigation method. The average yield of drip irrigation method was 7.2% less than the yield of furrow irrigation method and 27% higher than furrow irrigation method. Water use efficiency in drip irrigation to basin and furrow IRRIGATION METHODS, was higher about 28 and 52 percent respectively. Generally, drip irrigation method was the best treatment for all ONION CULTIVARS.
