RESPONSE OF RED CABBAGE TO THE ADDING WHEAT PEATAND SPRAYING WITH ITS EXTRACT AND ORGANIC NUTRIENT VEGEAMINO ON QUALITATIVE CHARACTERISTICS OF HEADS

Abstract

A field experiment was carried out at the Horticulture Dept. Fild– Coll. Agric,University of Baghdad , to study the response of  red cabbage to the adding  wheat peat  and spraying its extract and organic nutrient vegeamino on qualitative characteristics of  heads , using Raissa hybrid , during winter season of  2015-2016 . Afactorial experiment using Randomized Complete Block Design(RCBD) with threere plicaes were canducted , The  First fatcor includes five levels of  fertilizers , wethout-fertilizer (P0) , recommended chemical fertilizer ( 100 N ,120P205and120K2O  kg . h ^-1(  (P1) , organic fertilizer 7.5 tan.h^-1(P2) , organic fertilizer 15 tan.h^-1(P3) and organic fertilizer 30 tan.h^-1(P4), The second factor includes  four treatments  , spraying  only weter (E0)  , extracts wheat peat (E1) at a concentration  2 ml.L^-1 , organic nutrient vegeamino (E2) at 1 ml.L^-1  and  Interaction E1 + E2 (E3)  , The results showed superiority of organic fertilizer treatment P4 in  Vitamin C  content (76.0mg .100 gm^-1 ) , Folic acid (123.14µg.100gm^-1 ) , percentage oftotai  carbohydrates (4.593 %  ) , protein (18.823 %  ) , fiber (9.130%   ) and lowest content of nitrate in the head (0.390 mg.gm^-1 ) , E3  treatment showed a significant increase in the characteristicsaboveand gave greatest value  reached 71.50mg . 100gm^-1, 119.54µg.100gm^–1  , 4.257 %  , 17.702 %  , 9.190  %andlowest content of nitrate inE0treatment (0.449 mg.gm^–1), Interaction treatment of  P4E3 gave the greatest value   reached82.34mg.100gm^1-, 145.79µg.100gm^1-, 4.983 % , 20.516% , 11.790 %andlowest content of nitrate was  inP0E0 treatment (0.332mg.gm^–1 ).
