This p per g ve brief introduction on t he concept of redund ncy, its hypothesis nd redund ncy degree, nd briefly reviewed t he rese rch dv nces in redund ncy theory nd in the methodologies bout species redund ncy, l yer redund ncy , gene redund ncy , nd growth redun d ncy. A hypothesis of optim l growth redund ncy degree ( OGRD) w s proposed, i. e. , under cert in cultiv tion nd m n gement conditions, there existed growth redund ncy degree corresponding to t he highest crop yield, nd high y ield would be obt ined if OGRD could be chieved through the regul tion of m n gement pr ctices. The hypothesis w s tested by using the d t from highyielding rice cultiv tion c ses. Key words Redund ncy, Redund ncy degree, Optim l growth redund ncy degree, Agroecosystems m n gement. , ,
