In 2012 and 2013, to investigate the effects of N, P, K fertilizer to rice yield on Crop system of spring rice- summer rice-winter maize on degraded soil , the field experiments were conducted at Luong Phong, Hiep Hoa, Bac Giang. The experiment included 5 treatments with 3 replicates: (1) No fertilizer; (2) NPK; (3) PK; (4) NK; (5) NP; the fertilizer for spring rice (100N +70P2Os + 100K2O) per ha and (8ON + 8OK2O + 60P2O5) per ha. The research results showed that on spring rice- summer rice-winter maize, with 3 N,P,K elements for rice, N is the most influential factor to yield rice then to K, the nutrients from P nearby not affect yield rice, to the fourth crop, fertilizer use efficiency descending order N K P.
