| Abstract | ||||
| Six field experiments were carried out at EI· Minia, Assiout and Sohag governorates in farmer fierds during 1998 and 1999 seasons. The experiments were conducted to investigate the effeci of tillage systems and N fel'1i1izer combined with biofertilizer on grain yield of maize under farmer fields conditions. The experiments were in a split plot design, with four replications. Main plots devoted to tillage syslems and the sub plots to fertilizer rates. Results showed Ihet most Ihe studied characters were not affected by the tillage systems,however, almost characters under CT tended to increase slightly compared with no·lillage(Nn.while at Sohag the NT produced grain yields equal to those with CT. Results also, showed mat the application of biofertilizer{Cerealine) with mine ret nitrogen fertilizer at rate of 90kgN/fed or 120kgNffed increased growth , yield and yield components as compared to the treatments witho!)t Cereeline. The increment in maize yield by Cerealine+90kgN/fed and C£realin+120kgN/fed were 31.95 and 5.14% at EI·Minia 36.04 and7.53% at Assioul and 35.7 and 3.86% at Schag, respectively compared with the treatments without Cerealine. It could be concluded thot application 01 the biofertilizer Cerealine may be importance to enhancing maize yield with low rate of mineral N (90kg/fed) as compard to the high rete of N under tillage or no-liUage systems. | ||||
