Things to Do on a Rainy Day (IV): Crop Rotation Sudoku

Hours of fun....

Here is your Grid:

It is divided into two smaller internal four-square grids with an addititonal four-square row along the side and three squares left over along the bottom.

The game is to create a four-year rotation cycle using this grid, four times (one for each year).

Each square must be filled with your choice of vegetable crop from one of the five groups listed below, according to the following rules:

1)No square should contain the same crop as the one next to it.
2) You do not have to use all the individual crops suggested, and may if you wish, use some of them more than once - but there should be no more than two individual squares of the same crop in the whole grid.
3) To ensure healthy plants and good yields, these crops should rotate over the four years through the smaller internal grids/rows in the following order:

a) Nightshade Family
b) Pea Family
c) Brassica Family
d) Roots/Alliums

*If the crop you start with in Year 1 is from Group c) on the list, then your Year 2 crop will be from Group d), then it's back to the top so that your Year 3 crop is from Group a) and so on.

4) The following should not be planted in adjacent squares, as proximity may damage the yield of one or both crops:

Peas and Alliums

5) You may at any point choose to play a "Joker" by filling a square with one of the suggested salad crops, as these may be safely placed anywhere in the rotation scheme. There is no limit on the number of jokers you may play. Just bear in mind that there is only so much lettuce a normal human being can eat in one summer.

Nightshade family
Potatoes
Chillies
Cherry Tomatoes

Roots and Alliums
Parsnips

Tip: Try to account for the expected height of your selected plants, the amount of shade they will create on the squares around them, and which of your other crops will need lots of sunlight.

Enjoy!
