摘 要：The individual and combined effects of biochar(B)and inorganic fertiliser(F)have all been widely proofed to improve soil fertility and enhance crop growth and yield under irrigation(I)and rain fed ***,the strength of their individual and combined effects on crop productivity has been scarcely *** addition,few studies have assessed their individual and co-application effects on economic ***,a 2-year field experiment which consisted of factorial combination of irrigation(I)[100%full irrigation(FI),80%FI and 60%FI],biochar(0 and 20 t/ha)and fertiliser(0 and 300 kg/ha)was *** to the results,irrigation was the dominant factor that influences maize grain yield,followed by inorganic fertiliser and biochar,and they were all significant in their main *** strength of interaction effects among,I,F and B on maize grain yield follow the sequence F×IB×FB×*** economic analysis showed that the ternary combination of B,F and I was more economical than the binary combination of B plus I,and F plus I(in that order),when compared with the standalone application of I at maximum production in the field *** addition,combined applications of biochar and fertiliser improved soil nutrients,nutrient uptake in all irrigation treatments,compared to the standalone applications of biochar or *** research is,therefore,recommended for long-term evaluation of the economic viability of integrating biochar with fertiliser under irrigation.
