Abstract:
A pot experiment was conducted to study the improving results of iron deficiency symptom and effects on yield for Soybean plants applying different correction techniques in calcareous soil.The results showed that the period from before flowering to flourishing flowering was serious stage for soybean plants lack iron,which was the best stage of applying iron fertilizer.Organic fertilizer+ferrous sulfate(proportion 10 ∶ 1)as basal fertilizer was the best technique among all correction techniques which improved the symptom of lack iron nutrition and increased yield per plant also.Spraying chelate iron as dress fertilizer achieved higher yield and better improved the symptom of lack iron nutrition for Soybean than spraying ferrous sulfate treatment.
