Abstract
Rainfall distribution, water use, yield of onion, water use efficiency (WUE) and water use index (WUI) as affected by four increasing water quantities and three water qualities were studied in field pot experiments during 1991/92 and 1992/93. Results indicated that increasing the water applied, compensated partially for the adverse effect of increasing irrigation water salinity. Salts accumulation in the crop root zone was at the maximum in W3 (W3 = evaporation). With supplemental irrigation, winter onion production per unit area can be increased into two to three times non irrigated onion. Maximum WUE occurred in W3 and W4, while maximum WUI occurred in W1 (0.25 evaporation) and W4 (1.5 evaporation) treatments for irrigation water salinity <2.8 dS/m and more than 2.8 dS/m, respectively. The tolerance threshold soil salinity of relative onion yield varied from 2.43 to 3.6 dS/m, and the rate of relative yields decline above the threshold soil salinity varied from 8.4 to 21.5%. These results place winter onion grown in the Jordan Valley in the moderate sensitive to salinity category.
