| Abstract | ||
| Eleven sites with (0-30) and (30-60) cm depth presenting root area were selected to study boron contents in some Ninevah governorate soils. These soils which classified within a calciorthid soils had been analyzed chemically, physically and morphologically where their available boron were calculated by using hot water. Field surveying results showed that available boron of soils ranged between (1.57-9.34) mg B.kg-1. According to the fertility status the soils were considered as an average in boron supply for sugar beet. High significant correlation between available boron values were Ec (r = 0.282*), silt (r = 0.353*) and clay+silt ( r = 0.242*).Field experiment results indicated that there were different root yields according to these locations. The fertility estimation for boron concentration in fresh sugar beet roots and leaves ranged between (31-44.5) and (37-64) mg B.kg-1 respectively. This concentration range was within the low sufficient level which makes these locations lack of boron in the next agricultural seasons. So there is a need to increase boron concentration in soil solution due to application of boron fertilizer in the next agricultural seasons. | ||
