Study on Fertilization of Jobstears‘Puyi No.6’

In order to find out the effect of different fertilization levels on the yield of jobstears, an experiment with different fertilization levels was conducted with jobstears ‘Puyi No.6’ as material. The results showed that the yield of jobstears increased with the increase of fertilization amount, but decreased with the increase of fertilization amount when fertilizer amount increased to a certain level. The maximum yield and the best economic benefit per 667 m² were received by 264.8 kg and 704.8 RMB yuan of net income under the condition of applying N, P₂O₅ and K₂O were 20 kg, 20 kg and 20 kg, respectively.
