Abstract
To investigate the response of white mustard Sinapis alba L. sprayed with boron and potassium on growth and yield. Afield experiment was conducted during 2008-2009 and 2009- 2010 seasons at the experimental farm, Department of Field Crop Science, College of Agriculture/University of Baghdad .The layout of the experiment was a split–plot in RCBD with three replications .Boron concentrations (0,100,200,300 mg.L-1) were in the main plots while potassium concentrations (0,2000,3000,4000 mg.L-1) were in sub plots. Results showed that higher concentration of boron was superior in seed yield.ha-1 in increasing 42.14% and 56.36% for both seasons compared to control due to increases in silique. Plant-1 (453.2 and 478.2) and seed .silique-1 ( 11.2,10.8) for both seasons. Higher concentration of boron gave higher branches. Plant-1 ( 23.1 , 19.3 ) and higher plants (121.2,116.9 cm) for both seasons while higher concentration of potassium gave higher yield plant about 12.1 and 10.4 gm and higher seed yield about 1294.2 and 1472.8 Kg.ha-1 , more silique number per plant 447.6 and 480.3 and higher seed number per silique about 10.6 and 10.4 seed. Silique-1 and weight of 1000 seeds about 2.6 and 2.8 gm for both seasons. While the control treatment K0B0 gave least yield about 956.1 and 922.7 kg.ha-1 and least silique number about 320.7 and 310.5 silique.plant-1 and least plant height about 109.7 and 110.3 cm and least branch . plant-1 for both seasons
