| Abstract : A field experiment was conducted in the fields of a farmer in Mahaweel , 20 km North Hilla , Babylon center during the autumn season 2013 in silt soil in order to study the effect of foliar application of four concentrations of potassium ( 0, 100, 200, 300 mg K.L-1 ) as K0, K1, K2, K3 treatment and four calcium concentrations ( 0, 50, 100,200 mg ca.L-1 ) as Ca0, Ca1, Ca2, Ca3) added as K2SO4 and CaSO4 in growth and yield of maize cv. )Bhoth 106(.applied in accordance with the style of factorial experiments and randomized complet block design (RCBD) with three replicates was used. The results showed that the level 200 mg k.L-1 giving the highest average high plant,leaf area, leaf area index, number of rows per ear, number of grains per earn , grain yield , biological yield , and harvest index , (236.55cm,6188.7cm2 , 3.300,17.232 rowsear,537.1 grain ear,10.183ton.h-1,24.139 ton.h-1 and 42.16%) The treatments had no significant effect on number of ear and 500 grain whereas the concentration300 mg k.L-1 giving the highest content leaves form K 1.724 gmg and concentration 200 mg ca.L-1 giving the highest percentage Ca in leaves 1.442 gmg . Ca application and the interaction between K and Ca had no significant effect . Key words: Maize, foliar application of K , foliar application of Ca | ||
