Abstract：A “3414” design experiment was carried out to investigate the effect of nitrogen(N),phos-phorus(P) and potassium(K) application amount on the yield,economic benefit and fertilizer efficiency of tartary buckwheat in Jintang county of Chengdu. The results indicated that the yield of tartary buck-wheat of the treatment with fertilizer was significantly higher than that of the treatment without fertilizer, the yield of tartary buckwheat and the net income increased first and then decreased with the increase of N,P and K application amount. The input and output ratio decreased with the increase of P application amount,and increased first and then decreased with the increase of N and K application amount,indicating that appropriate reduction of the P application amount and increase of N and K fertilizer application amount could attain higher economy benefit. The combination of any two of N,P and K was beneficial to improve the fertilizer efficiency for another fertilizer at a low level. Above all,the application of 39. 8—86. 0 kg / ha N,74. 6—161. 2 kg / ha P2 O5 and 29. 8—64. 4 kg / ha K could obtain 2 000—3 500 kg / ha tartary buckwheat at 95 percent probability,and which was worth generalizing and applying.
