Effects of water, salt and nitrogen stress on sunflower (Helianthus annuus L.) at different growth stages
2016
Journal of soil science and plant nutrition
Experiments in soil columns were conducted to evaluate the single and interactive effects of water, salt and nitrogen stress at different sunflower (Helianthus annuus L.) growth stages in Hetao Irrigation District, China. The study factors included soil salinity (S 0 : EC e =2.5-3.6 dS m -1 ; S 1 : EC e =9.6-10.7 dS m -1 ), soil moisture (W 0 : 35 %-55% of field water capacity; W 1 : 75%-100% of field water capacity), and nitrogen application rates (N 0 : 0 kg N ha -1 ; N 1 : 135 kg N ha -1 ).
