First:
here (
http://lineage2.stratics.com/content/features/manorsystem/) is good manor guide, pretty complex description of what is needed. May be a bit C3 according to images, but basic is still the same. Also do some search on General discussion and Player guides forum on this beard.
Buy seeds from manor manager (they are in every town, but not sure about Dwarven and Orc village). Buy harvester. Check for seed levels - they have their range, your and mob's range has to be within it. Also check for what area you buy it - you cannot use oren seeds on Gludio's mobs and vice versa. Prior to killing a mob, seed the seed you purchased - use it, best to put it on hotbar. Status message will inform you if seeding was successfull or not. After mob dies, use harvester on it. Status message will inform you if harvesting was successfull or not, and how many fruits you obtained. Rince, repeat, until you seed all seeds. Then return to manor manager to exchange fruits for reward Reward is mostly basic materials necessary for crafting.
For details like how to raise success rate, how to get most fruits, how to exchange for materials with best buyback see hints in first paragraph.
Seeding eliminates standard drops - with exception of Alternative seeds. They do
NOT eliminate quest item drops, event items drops including sealstones, spoils and adena.
Second:
It's hard to get some drops in Lineage][ ... I would say they are pretty rare. Speacially full item drops. If you want to get some specific weapon or armour parts, it's best to find what monsters drop them, and try to farm those mobs. Sometimes it takes pretty long time to "farm" for something, sometimes you have all key items collected within one evening. Unfortunately there is no official information on drop tables, you have to relay on third party sites or other sources.
It's hard to get equipment at start ... usually first character is always broke until like 50s or so... sometimes always :-) Making "farming" alt helps - usually dwarf with spoil ability to get extra items, plus utilising manor system to it's max. Do not be dusguised by the fact your first character is broke with crappy equip ... for example my alt dwarves earned me Divine set prior I hit 40, and Blue Wolf just when I hit B grade. Finding clan that keeps you in parties and help gettign equipment always helps. Plus there are more effiient ways of getting adena than farming monsters ad infinitum ... manor system, 7 signs mammon trader and blacksmith, playing market, and do not forget quests.
If you expect to do any pvp, roll mage or archer ...
