     Some vegetables need a lot of sunshine.A vegetable expert at the University of Marine advised planting these vegetables where they can get eight to ten hours of sunlight a day. Tomatoes, melons, squash and peppers are among those that need the most sunshine.    

     Farmers often feel it needs a lot of sunshine to produce a good crop.  The Rodale Institute in Pennsylvania, however, says that lots of vegetables grow well without much sunshine. The research center published a report about this subject some years ago in its magazine' Organ,ic Garden,in,g. The report says many different kinds of crops from bluebemes to beans can be grown in the shade.      

     The Rodale Institute says a garden should be planned carefully especially if you grow different kinds of vegetables.  For example, rows of vegetables should be planted in an east-west direction.  In that way, as the sun passes overhead, all the plants will receive an equal amount of light.  This is especially important when the plants grow to different heights.
