Abstract
The study were conducted at 2001-2002 to study the effect of fertilization and early clipping on yield and its components of four bread wheat varieties (IPA - 95 , Abu - Graib ,
Rabia , Adnania ) . The plants were fertilized with 60Kg/ha of compound fertilizer NPK(27:27:0) and clipping once during the tillering stage . Result indicated the superiority of fertilizer in plant high , on of spikes/m2,seed index , grain and straw yield and harvest index , high significant value in grain and straw yield found in IPA-95 variety . The interaction between fertilizer with clipping and Non clipping treatment was significant for plant high , no of spike /m2 no of grains/spike , seed index , grain and straw yield and harvest index , IPA-95 variety with fertilizer and with clipping and non clipping gave high grain and straw yield the interaction between (IPA-95) X clipping X fertilizer treatments gave superiority grain and straw yield production .
