Depending on where you are at and what you are already doing.

You want to use RAMS only plus your Hero

You want to where/when possible only yield ALPHA'S or L6 Tiles (That means hanging in the Dark Forest)

You want to fuse materials/craft hero equipments to help in an indirect way.

Meaning, Craft gear that will enhance; food production (sustain more RAMS per hour)

march speed, sliver production (to buy gear). 

You can fuse and add gems to give you small % gains as well. (very small)

This is doable from a Level 8 castle right up. At lower levels 8-12 Castle. Craft Hero gear at about level 17 Hero, see above.

Yield tiles using 5-10K troops and watch them.

At higher levels, say 18 Castle your Hero will be 40+, craft better gear, as above.

With your Hero and 10K+ RAMS you can Yield 250-400K from an ALPHA Tile in 4-8mins. approx.

At this point you'll have 4 Marches. Yield 1 tile with Hero and Troops, another two tiles as well if you're game and run your Inquisitor.

Speeds from fastest RSS to slowest to yield:

FOOD

LUMBAR/IRON

STONE

SILVER (which is worth 2x points in yield event)

If you don't really need the silver sometimes just for points I'll go for food, which is fastest.

The Ultimate:

Yielding FOOD ALPHA tiles with a Geared up Hero and lots of RAMS.

Two more important areas:

ACADEMY STUDIES:

Go to Economy and Resource Yielding 1 start studying till this starts to fill

and also above that Capacity will increase what your troops can carry

HERO SKILL POINTS:

Go down the right side to Resource Yield 1 and fill

When you get more points go to Resource Yield II & fill.

You might start with the top two Building & Study Speed at 1/10

But get these to at least 5/10 to help build & study.

You can always come back and reset and create profiles, 

One for Yielding/Build/Study

Another for Fighting

RAM is a siege tier I

You should  yield ALPHA'S or L6 Tiles

This is top gear for Yielding & I forgot VIP have increased marches headcount, marches speed & troop capacity, higher VIP lvl more increased

That's capacity, not yield speed. The OP was talking about yield speed. Different beasties. (*) You can always send more troops, you can't otherwise take less time to empty a camp. Don't forget the 75% yield increase (which seems to have little impact on alpha camps), and the +175% troop increase to one-off increase your march size.

(*) About the only time more troops is insufficient is a 5.8M L7 food camp.

As probably said, biggest factor is higher level camps / Alpha camps.

The only time this -REALLY- matters, is during events and yielding Alpha camps - and needing the total duration to be under an hour. So that a single 1h safe conduct will let you breathe in peace. Having to use 2 for 1.5h duration is just annoying! :)

Anything less than alpha camps is just too slow. But then, at least it lets you use up the otherwise pointless 3h safe conducts.

-----

** I really wish Plarium would indicate yield duration when sliding troops for capturing a tile. Then you'd slide up to the 1h  and hit 1h safe conduct once you land. You may not get the entire tile and the extra goodie, but at least you'd come back safe and with the provisions.

This is the equipment cheat sheet on this I made up for myself some while back.

Each list stops at the highest point of some equipment I'm already going to get. I may pursue better, but I will at least have the last. e.g. Amarian Blued Canteens are used with Study gear, so there was no point searching further for high yield gear that would be lower than it. Same with Bec de Corbin.

If there is no % listed, it probably means equipment likely to be on hand and the best of poor choices for that moment. [Early on, with few profiles, needed gear is too expensive to sidetrack oneself with, for the very marginal benefit gained.] Absent yield speed, capacity and march speed seem to be the next best factors to consider.
