Poor crop yield is one of a farmer's worst nightmares.
Worse than him losing his pension. Worse than him losing his wife to another man.
No grower prays to spend so much time, money and energy only to reap just a tiny fraction of what he expected.
It hurts. It irritates. It makes a man feel less than pig.
Harvest is the most exciting period in a farmer's life cycle. It can quickly turn sour however if produce that ought to be full and fat comes out scarce and thin.
Angry ancestors and mean gods used to bring the ill-wind of poor crop yields. But no more.
These days, a lot more boring factors are at fault.
Knowledge is key.
