AgriCraft ReReloaded is a fork of AgriCraft Reloaded (fork of AgriCraft), which aims to fix the remaining issues of the port and bring back missing functionality.

Currently supported - 1.21.1.

AgriCraft is a mod which aims to bring crop breeding to Minecraft, this includes both improving your existing crops, or cross-breeding to mutate into new species of crops.

The mod has been entirely rewritten for 1.16.5, so for both the apprentice and the expert, it might be opportune to give this a quick read.

Genetics:
AgriCraft follows mendellian genetics, this means that the genome of a plant consists of a series of genes, where each gene appears as a pair of alleles. Usually, one allele is dominant over the other, the latter being called recessive.

For instance if we consider gene "A", with dominant allele A and recessive allele a, the following holds:

Gene Pair A-A: both dominant, A will be the apparant trait;
Gene Pair: A-a: A is dominant over a, so A will be the apparent trait;
Gene Pair: a-a: both recessive, so a will be the apparent trait.

AgriCraft contains multiple genes by default, examples of genes are the plant species, each of the stats, and attractiveness to certain animals (yes, be careful as a cow might be very curious about that tasty, tasty 10-10 wheat, however this might have certain advantages as well. For instance for stats, a higher stat level is dominant, so a plant with Growth genes 8 - 3 will have an actual growth stat of 8.

When cross-breeding two plants, the child crop will inherit one of the two alleles from each parent, so for instance two 10 - 1 crops can have the following offspring:

10-10: inherit the 10 from both parents: 25% chance
10-1: inherit a 10 from the first and 1 from the second, or vice versa: 50% chance
1-1: inherit the 1 from both parents: 25% chance

Now when this happens, sometimes a mutation can trigger, this means a random change in one of the genes, for instance an existing plant species might mutate into a new one, or a stat might go up or down randomly. Mutations are key to improving your crops and unlocking new ones.

Stats:
AgriCraft contains 6 stats by default:

Growth: affects the growth rate of plants, meaning higher growth stat leads to plants reaching maturity quicker;
Gain: affects the number of fruits that the plant will produce;
Strength: affects where the plant can grow (see Growth Requirements);
Resistance: affects how resistant the plant is to weeds (see: Weeds);
Fertility: affects how likely a plant is to participate in cross-breeding to produce offspring;
Mutativity: increases the likelihood of a positive mutation when cross-breeding;

Weeds:
Ugh, weeds, noone likes weeds.

Well they are back, but not as you know them, instead of randomly killing plants, they will now sprout on existing plants and grow in parallel, competing for precious resources and thus delaying the growth of your crops.

It is recommended not to let them mature, as when weeds reach maturity, they tend to constrict and eventually kill their host plant as well as spread to neighbouring crops.

Growth Requirements:
Plants will now have very specific requirements related to the soil, season, fluids and light. Each soil has certain properties such as humidity, acidity and nutrients, and some crops like very humid soils, while others prefer soils which have very little nutrients. Furthermore, if you have a mod installed that adds seasons, AgriCraft crops will recognize these, and grow only during their favourite seasons.

It is also rumoured that some crops must be cultivated under water to grow.

Irrigation Systems:
AgriCraft adds Irrigation Systems to water and speed up the growth of your crops.
