[READ] Weeds do not reduce yield 20 percent

Post by FarmDemAcres » Mon Jun 10, 2019 1:20 am

Any news from this original report? I still don't see a 20% reduction in yield with weeds present. Just curious, as a work around I simply don't weed :/

PC/Mac/PS4/XB1: xb1
- Vehicle/Tool/Model/Object: any
- Issue: Crops yields are not reduced when 100% weeds are indicated at harvest
- Single- or Multiplayer: single
- Steps to reproduce: Ravenport lot 21 (.99 ha) as an example. Harvest soybean with 100% fertilizer and lime with 0% weeds is 8890, with 100% weeds is 8882.
- Does it happen on a standard map without mods yes/no yes

Did you turn off weeding in the game options?
I guess weed will still grow, but has no effect.

Weeds are on. Prior to harvest confirmed that field info indicates 100% weeds. Also this occurs with weeds in full flower, not just small growth stage.

I just tested this on PC - Steam Version.
Felsbrunn field 21.

100% weed is giving expected yield loss of 20% on the base yield. This ends up in 10% total yield loss compared to a "perfect" field in the end.

Edit:
Test was done for WHEAT.

Perhaps this is a console issue? To confirm I just ran a test on PNW (my current favorite map!)
Lot 22 soy is at last growth stage, 100% weeds and fertilizer, lime and plow are not needed. 100% repair on harvester and header. Save game and wait for harvest time. Afterwards the in-game stats page indicates 1.63 ha of soy harvested, actual yield is 14397 liters. After quit and reload (autosave off) then spraying with small tractor on care wheels. In game stats page reports 1.63 ha "fertilized" and harvested, actual yield 14534 liters. Let's see, at my current market prices that's an increase of 137 liters netting me a whopping $217 additional income. The "perfect" harvest of 14670 is rarely achieved I expect, but even so this amounts to about a 2% decrease with weeds at most.

But oops, I sprayed 511 liters of herbicide, costing me $818.

I think I will still let the pretty flowers grow for now :)

Ok, final testing on my end.
PC - Steam Version - 1.3.0.1
No Mods, Felsbrunn, Fresh start on Farm Manager

1. Test fields were fully fertlized and limed. Some needed plowing, see below.
2. I prepared the fields and set up the harvesters (one per each field) and saves the game before weeds coming up.
3. Weeds are removed with sprayer, time accelerated to first harvesting stage
4. All fields harvested, yield documented
5. Game reloaded, weeds not removed, time accelerated to first harvesting stage
6. All fields harvested, yield documented

As the weed influence of 20% (like all other influences) is calculated against the base yield (see maps_fruitTypes.xml), expected yield difference is 10% for a perfect field, while 10.81% for a perfect field needed plowing.

As you can see below, only wheat is behaving as expected when it comes to weed influence.
