Abstract: An experimentation on the N, P, K, and manure fertilizations was conducted in the tea producing areas in Pinghe County for two consecutive years to study the responses of Baiya Qilan tea to the various fertilizations for a recommendation on the cultivation. Based on tea yield, a system clustering analysis divided the plantations into high-, medium-, and low-yield classes. Regardless of their classifications, significant differences were observed on the average leaf yields between the plants under control and balanced fertilization applied on the plantations. The increases on yield over control due to the N, P, K, and manure fertilizations averaged 13.9%, 5.5%, 11.3%, and 11.6%, respectively. Among the plantations of different classes, N or P fertilizer showed a highest effect in the high-yield field. On the other hand, K or manure was more effective in the low-yield than the high-yield field. The net revenue of the high- or medium-yield tea plantation with N fertilization was higher than that of P, K, or manure. At the low-yield plantations, N or K rendered a similar financial return as manure fertilization did; while P, the least among all. Accordingly, it was concluded that, on average, the optimum application rates for the tea plantations on N, P, K, and commercial organic fertilizers were 347 kg N·hm^-2, 105 kg P₂O₅·hm^-2, 116 kg K₂O·hm^-2, and 3,750 kg·hm^-2, respectively. And, for the medium- and low-yield plantations, it would be most effective and desirable to use appropriate applications of N and K; whereas, for the low-yield tea fields, a combination of organic and chemical fertilizers was recommended.
