Effect of magnetically treated water irrigation and manure on vegetative growth parameters and yield of cauliflower

Abstract

An experiment was conducted in field belong to Plant Production Department / Kufa Technical Institute during the period from 15/9/2011 till 12/1/2012 . The aim was to study the effect of four levels of magnetically treat water irrigation ( i.e.without treatment , 500 , 1000 , and 1500 Gaus ) and three levels of organic fertilizer (i ,e ,without fertilization,100 and 200 g/plant ) on some vegetative growth parameters and curd characteristics at harvesting of cauliflower cv. Ruba . Results showed that irrigation with magnetically treated water in general reduced the values of soil EC and pH ; P , K , and Ca were more or less reduced or increased depending on water treatments . Meanwhile , organic fertilizer that added to the soil reduced the values of P , K , Ca , Na and Cl . and the effect increased with the increase in the level of added organic fertilizer . Soil EC and pH recorded a slight increase with the increase of organic fertilizer . On the other hand , the highest values for vegetative growth parameters and curd characteristics were produced from the use of treated water with 1000 Gause accompanied with the use of 200g/plant of organic fertilizer . The highest values for the measured parameters were : 25.2 leaves , 1155.0g . , 128.0g . , 17.2cm . and 832.0g . for leaf number and its weight , stem fresh weight ; curd diameter and its fresh weight , respectively , compared to 19.0 leaves ; 515.0g .; 50.0g . ; 9.8cm . and 239.7g . respectively , for the above studied parameters obtained from plants of control treatment .
