Effect of Sewage Sludge , Humic acid and mineral sepray of some traits of Califlower

Abstract

Abstract : This experiment was conducted at research center of Babylon to study effect of sewage sludge that add 20 tan .ha-1 , humic acid that add 2 and 4ml.L-1 and mineral spray that spray 2gm.L-1 on some traits of Califlower and lees of chemical fertilizer . The experiment was conducted by Randomized Complete Block Design ( RCBD ) . The results showed that : The sewage sludge was increased significantly on control at per of head show after 4 months' from planting(86.73 %) , rate weight of siresh head(427gm) , rate whigt fresh and dry of vegetative growth(3.17km,564gm) and Ca % (1.24%) .The humic acid treatment 2ml increased significantly on control treatment at chlorophyll spad (57.88 spad).The mineral elements spray non increase significantly on control in this study traits .
