Abstract

In order to study the effects of different amount of nitrogen, phosphorus, potassium and all the fertilization ratio on sweet corn yield "3414" design theory was applied to set sweet corn fertilizer efficiency test in Wuhan city modern agricultural experiment and demonstration garden. Result showed that the yield of sweet corn was significantly affected by different amounts of fertilizer and different fertilization ratio. The yield of treatment7 (N2P3K2) was the highest, reaching 13477.5 kg/hm2 when that of no fertilizer (N0P0K0) treatment was 10870.5 kg/hm2. The difference of yield was significant. Compared with the different dosage of nitrogen and phosphorus and potassium, it found that while the other two fertilizes kept unchanged only increased a single use of another fertilizer, the sweet corn yields increased with the fertilizer at first and then decreased when continued to improve the amount of the fertilizer treatments. Results showed that the treatment of no potassium had a notable effect on sweet corn yield. Contrasted with the nutrients deficiency no phosphorus treatment had less effect on sweet corn yield and no nitrogen treatment had minimal effect on sweet corn yield. Potassium fertilizer is the key factors. It should be consideration of the reasonable application of fertilizer in fields.
