Abstract
This study done in field of agriculture colloge - Tkrit university – Salah AL- deen prirence for the years 2008-2009 at autem season. by sowing the crop of sugar beet kind of Aupole mult-emlryo to study the best centering of Bron and best numbers of spray to get the best greengrocer growth and higbest result in gypseous soils. Fertilizer of boron used as Bori aci d (17%B) with Four centrings which are (0,105,175,200mg.L-1) and two spraying whish are the( first spraying and scond spray) the features that studied. are Fresh weight of leafs and roots ,leaf space total product of roots , product of crude sugar , precent of sugar and total of hard soluble materials , purity and the root content of boron the results shows that the number of sprays have no abstract effect in all of the Features except the features of leaf space and percent of purity but, the centrings of fertilize give abstract differents and the both centrings gives the best abstract different in all of the features but these differences was so littele between the both centrings . but for the overlap –both centrinsg (175,200mg.L-1 ) gives highest abstract different to each the First spray which gives positive resultes to all of the Features of the product and the type and also the root content of boron . according to thes results we can conclude that the best result at the both centring (175 mg.L-1 ) with one spray wich means the used of these contrings with one spray sufficient to give the best result .
