The Effects of Different Application Rates of Organic Fertilizer on Maize Yield
In order to study the effect of different organic fertilizer application rates on maize yield,'Zhengdan 958'was used as the test material,with single application of chemical fertilizer as the control(CK).Five treatments were set up:T1 treatment with 1000 kg/hm2 of organic fertilizer,T2 treatment with 1500 kg/hm2 of organic fertilizer,T3 treatment with 2000 kg/hm2 of organic fertilizer,T4 treatment with 2500 kg/hm2 of organic fertilizer,T5 treatment with 3000 kg/hm2 of organic fertilizer.The study examined the effects on agronomic traits,ear traits,and maize yield.The results showed that compared with CK,the application of organic fertilizer significantly increased the plant height,ear height and stem diameter,reduced the bald tip length and empty stem rate,and improved the seed setting rate,grain number per ear and thousand grain number.The yield of T4 treatment was the highest,which was 27.61%higher than that of CK.It's evident that adding 2500 kg/hm2 of organic fertilizer to conventional fertilization could significantly promote the maize growth and increase the yield of maize.
