RESPONSE OF DIFFERENT CORN (Zea Mays L) HYBRIDS TO FOLIAR FERTILIZATION DURING THE GRAIN-FILLING PERIOD

Abstract

                                The response of eight com hybrids, ( Wf * 8W * 22 . 17N * 28 B37x W19, B * 37B * 70 B * 70B * 73 873x Mo14, Q97xQ98 and Q51x Q52) to foliar fertilization during the grain- filling period was investigated. Of these eight hybrids, only the hybrid (Q51x052), a two-earred hybrid showed a significant (P < 0.05) positive respone to foliar fertilization, and was therefore recommended as a potential candidate for further foliar fertilization studies and subsequent cultivation, Foliar fertilization had a significant effect (P < 0.1) on mean ear length but this was not associated with grain yields. The effect of foliar fertilization on seed weight was not significant.
