Let F be a nonformally real field, n, r be positive integers. Suppose that for any prime number pn, the quotient group F */F *p is finite. We prove that if N is large enough, then any system of r forms of degree in N variables over F has a nonzero solution. Also we show that if, in addition, F is infinite, then any diagonal form with nonzero coefficients of degree n in |F */F*n| variables is universal, i.e,, its set of nonzero values coincides with F * Bibliography: 4 titles.
