Abstract

     A field experiment was conducted at educational farm of Nasser's Faculty of Agriculture Sciences – university of Aden – Lahj Governorate, during the two auricular seasons 2014 – 2015 and 2015 – 2016, to study the effect of different of fertilizers and Plows  on the characteristics of crop and its components of (Zea mays  L.) Kanja 36   with 16   treatments , four type of fertilizer ( no fertilization , CYM , urea 110 Kg Nitrogen and FYM), and four tillage systems   i.e. no tillage , tillage with mold board plough ,tillage with disc and tillage with chisel plough). The results showed the Application of different types of fertilizers have been significantly  increased (Cob length , Cob width , Cob weight , number of rows cob،  number of grains per row, weight of grains per Cob, , 1000 Kernel weight, inattention ratio),  while CYM + urea treatment had significant effect on grain yield and husk yield, compared with control one (no fertilization) . Different types of fertilizers had o significant effect on the number of cobs per plant ,The highest values in all apartments under study were observed where CYM + urea  was applied .  and that’s tillage with mold bored disc plough had significant effect an  cob length and different types of plows  mold board , Disk and chisel  had  significant effect on the  width of cob, number of rows per cob, number of  g rain per row cob, 1000 kernel weight.
