Since your picklist field is on a Visualforce page, you can use some jQuery magic...

 

Give your field a unique id.

 

<apex:inputField value="{!My_Picklist__c}" id="myPicklist" />

 

Then, remove the option with the blank value as follows:

 

<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.6.4/jquery.js"></script>
<script type="text/javascript">
    $(document).ready(function() {
        $('[id*=myPicklist] option[value=""]').remove();
    }); 
</script>

 We can not remove None option directly becaus this inputfield ( pickiist Type). We need to make our custom pick list .

Here is a way to create custom pick list 

<!-- Page: -->
                        
<apex:page controller="sampleCon">
    <apex:form>
        <apex:selectList value="{!countries}" multiselect="true">
            <apex:selectOptions value="{!items}"/>
        </apex:selectList><p/>

        <apex:commandButton value="Test" action="{!test}" rerender="out" status="status"/>
    </apex:form>

    <apex:outputPanel id="out">
        <apex:actionstatus id="status" startText="testing...">
            <apex:facet name="stop">
                <apex:outputPanel>
                    <p>You have selected:</p>
                    <apex:dataList value="{!countries}" var="c">{!c}</apex:dataList>
                </apex:outputPanel>
            </apex:facet>
        </apex:actionstatus>
    </apex:outputPanel>
</apex:page>
            
/*** Controller: ***/
    public class sampleCon {
        String[] countries = new String[]{};
            
        public PageReference test() {
            return null;
        }
            
        public List<SelectOption> getItems() {
            List<SelectOption> options = new List<SelectOption>();
            options.add(new SelectOption('US','US'));
            options.add(new SelectOption('CANADA','Canada'));
            options.add(new SelectOption('MEXICO','Mexico'));
            return options;
        }
            
        public String[] getCountries() {
            return countries;
        }
            
        public void setCountries(String[] countries) {
            this.countries = countries;
        }
    }

The problem with this is that it works on document.ready but once you pick a value and then if you drop the picklist down again, 'none' shows up again. I am trying to figure out how to handle this. I tried the following but it didn't quite work: $('[id*=myPicklist]').change(function(){
$('[id*=myPicklist] option[value=""]').remove();
});
