The Effects of Reducing Nitrogen Fertilizer Application on the Yield and Quality of Super Rice Weiliangyou 8612
To investigate the impact of reducing nitrogen fertilizer application on the yield and rice quality of Weiliangyou 8612,and to determine the feasibility of reducing nitrogen fertilizer application in production,five levels of nitrogen fertilizer application were set at 0(N0),50(N50),100(N100),150(N150,general nitrogen fertilizer application amount),and 200 kg/ha(N200),a three-year field experiment was conducted to test its yield,yield-related traits,and rice quality.The results showed that compared with N150,appropriate increases(N200)and reductions(N100)in nitrogen fertilizer application did not significantly increase or decrease the yield of Weiliangyou 8612,nor did it have a significant impact on rice processing,appearance,and cooking quality.However,reducing nitrogen fertilizer application reduced the protein content of rice,which was helpful for improving the taste quality.In conclusion,under the condition of medium to above soil fertility,super rice Weiliangyou 8612 had no significant yield reduction under the treatment of nitrogen reduction(N100).Furthermore,processing and appearance quality indicators were not sensitive to nitrogen application rate,and a reduction in nitrogen fertilizer application leaded to a decrease in protein content,which could improve its taste quality.
