Nitrogen Rate on Root Growth and Heading of Pepper
In order to evaluate the nitrogen (N) rate on root growth and heading of pepper,the experiment was conducted with five N treatments in pots.The five N treatments named N1,N2,N3,N4 and N5 were 0,1,2,3 and 4 g N per pot,respectively.The results showed that appropriate N rate increased SPA D reading,dry matter,root growth,and flower of pepper.Length,surface area,length per volume,and volume of pepper mot increased in appropriate N rate.Appropriate N rate promoted early flowering and more flower spike of popper.However,excessive N rate reduced SPAD reading,dry matter,mot growth,and flower of pepper.Length,surface area,length per volume,and volume of pepper root decreased in excessive N rate.And excessive N rate delayed flowering and reduced the flower spike.Therefore,the appropriate N rate is 1 to 2 g per pot of pepper in this container experiment.
