The results obtained on 2 chernozems in southern Romania, by applying N, P and K fertilizers alone or together, for increasing the maize for kernel yield were discussed. A yield increase of over 12 q/ha was obtained by applying N fertilizers; the P and K fertilizers gave a 2-3 q/ha yield increase. N-P interaction was higher on the chocolate chernozem, as compared to the leached chernozem, and oscillated from yr to yr, from very positive to very negative.
