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.
