| Field experiment was conducted at field department of Horticulture at Agriculture of college , The University of Diyala in the autum season of 2007 – 2008 The soil was silty clay Loam , the aim of study the effect of seeding date and phosphate fertilizer on growth and yield of ( Trigonella foenum graecum L) . Twelve treatments included three seeding dates ( 15/11 , 1/12 and 15/12) with four levels phosphate fertilizer (0 , 200 , 300 , and 400 ) Kg P2O5/ha The experiment was factorial arranged in RCBD with three replications . the results show that : significant increased in plant hight , number of branches per plant , number of pods per plant , The dry and wet weight of root and vegetative branches and dry pods yield / ha where resulted from (400) Kg P2O5/ha . while heighest values of pod wet weight , where resulted from (300) Kg P2O5/ha . The early planting on 15 Novemper increased significantly of plant height , number of pods per plant , The dry wet weight of root and vegetative branches , wet pod weight and dry pods yield / ha . The lnteraction showed highly vegetative branches and dry pods yields (14.9) gm / plant and (657.8) Kg /ha respectively which obtanined by seeding date 15/11 and high level of phosphate (400) Kg P2O5/ha , compared with low vegetative branches and pods dry yield (2.8) gm / plant and (43.3) Kg/ha respectively , obtained by seeding date 15/12 and without phosphate fertilization. |
