| ABSTRACT: A field experiment was conducted during 2010-2011 and 2011-2012 seasons at the experimental farm, Dept. of Field Crop, Coll. of Agriculture, Univ. of Baghdad to study the response of wheat Shaam-6 cultivar to boron foliar and potassium application on growth Characters. RCBD with three replications used with split plots. The main plots was rpresented by potassium levels 0, 120 and 240 Kg K.ha.-1, and the sub-plots was rpresented by boron foliar with three concentrations 0, 200 and 400 mg B. L-1. Results showed that significantly effect for Potassium. Potassium application in 120kgk.ha-1 was superior in number of tillers (445.70, 465.00) branch.m-2, dry weight for both seasons (393.20 ,333.20)gm (55) days after sowing,( 958.90 ,970.40)gm (95) day after sowing, plant height (78.02 ,80.68)cm, leaf area (41.80, 43.59)cm-2, dry weight for flag leaf (1.026,1.088)gm, spike length (10.68 ,10.94) cm Als, high Crop growth rate for both periods (55,95) days after sowing was (6.16 ,6.30) ,(10.09 ,10.31) g m-2.day and higher releative growth rate for both periods (55,95) days after sowing was (0.1058 , 0.0722 ) and ( 0.1062, 0.0724 ) (gm.gm-1.day-1) for both seasons resepeaddition. In addition on, the result showed significant different between boron concentration for all growth characteristics. Boron foliar with 200mg.B-1 concentration gave highe rate for all characteristics such as number of tillers (466.80 ,477.40) tiller m-2 and dry weight (55, 95) days after sowing (323.30, 333.20) gm (933.80 ,970.40) gm, plant height (77.42 , 80.69) cm, and leaf avea for flag leaf, (42.39, 44.60) cm-2, dry weight for flag leaf (0.968 ,1,033) gm, spike length (10.38 , 10.62) cm, and high Crop growth rate for both periods. Days after sowing (5.87 ,6.05) and( 9.82 ,10.21)gm. m-2.day-1 and higher releative growth rate for both period (55 ,95) day after sowing (0.1047, 0.0719) (0.1053, 0.0723)gm.gm-1.day-1 for both season respectively. The interaction between both study factors was not significant for most growth characteristics for both season except dry weight for flag leaf for when K1B1 gave higher rate (1.277, 1.343) gm for both season. | ||
