The comprehensive effect of water, fertilizers and salt on wheat yield in desalted damp soil in Heilonggang region


, : The comprehensive effect of water, fertilizers and salt on wheat yield in desalted damp soil in Heilonggang region. Research of Agricultural Modernization 15(6): 364-368

In field trials in Heilonggang, wheat was grown in soil with 0.149, 0.180, 0.198 or 0.226% salt, irrigated with 0, 1200 or 2400 msuperscript 3 water/ha and given 210 kg N/ha with 105 or 210 kg P2O5/ha. Grain yields decreased with increasing salt level, were increased by irrigation and increased with increasing rate of P fertilizer. Increasing amounts of salt decreased the K content of leaves and stems but increased the contents of Na and Ca.
