This code is for my lemon seed which is created in my Items Class with all my other items. Posted lines seperatly so you could see which line(s) i'm talking about.

lemon_seed = new ItemSeeds(SlurpiesDonglesBlocks.lemon_crop, Blocks.FARMLAND).setCreativeTab(SlurpiesDongles.tabSlurpiesDongles).setUnlocalizedName("lemon_seed");

GameRegistry.registerItem(lemon_seed, lemon_seed.getUnlocalizedName().substring(5));

registerRender(lemon_seed);
