A
Study on Irrigation Scheduling of Onion (Allium cepa L.) in Turkey
Abstract:
This study was conducted to analyze the response
of onion (Allium cepa L.) to different irrigation scheduling
and subjected to four irrigation treatments during the years of 1997
and 1998 according to available soil water depletion fractions of 0.30,
0.50, 0.70 and no irrigation. The yield and yield components except
solids soluble in bulbs were affected by irrigation and soil water depletion
fractions. The highest yield was obtained from the plots in which irrigation
water was applied at soil water fraction level of 0.30. Maintenance
of soil moisture depletion level at 0.30 required 339.4 mm and 227.2
mm of irrigation water in 1997 and 1998, respectively. The seasonal
evapotranspiration of onion was 420.0 mm in 1997 and 351.2 mm in 1998.
