| Abstract | ||||
| Lyzimeter experiments were conducted at Sakha Agric. Res. Station during the summer season (2000) and winter season (200012001) to study the effect of the continuous or alternating low quality water (sewage, well and drainage water) with fresh water under surface and sub- surface lirrigation at 25 and SOcm depths on soybean and sugarbeet yield and their components. plant elemental contents, soil salinity and SOIl elemenml contents. The data reveal that the alternative irrigation by low quality water with fresh water achieved the highest yield and yield components for soybean and sugarbeet while the continuous irrigation with low quality water led to significant decrease in the yields of both crops. Also, surface irrigation su assed sub- surface irrigation in increasing total biomas for both crops. It could be observed from the results that fresh water gave the highest yield ollowed by sewage water and drainage water, while well water alone or mixed with sewage water gave the lowest values of yield. The irrigation with sewage and drainage water as well as well water directly or belended with sewage water led to an accumulation of elements in plant tissues but they stil' within the acceptable ranges. On the other hand, the soil salinity contents after harvesting of each crop were clearly increased under all treatments compared to those obtained before planting. On the contrast, SAR values in soil solution after harvesting were lower than the values recorded before planting. The soil contents of available macro, micronutrients and heavy metals were increased by using low quality water for irrigation. | ||||
