Watermelon – weeding and green manure in lowland tropics

Watermelons are commonly grown and some farmers believe weeds are good for the melons.

However, we figure that weeds do three bad things.

  1. Drop lots of weed seeds to become a problem in the future
  2. Compete with melons for water- a real problem in dry season
  3. Compete with melons for soil fertility- a problem year round.

We established a simple trial with 40 plants.

Twenty were weeded and had kedongdong leaves from a nearby tree spread all around the young watermelons.

Twenty were left alone, no weeding.

Within just a few weeks the farmer was convinced of the value of weeding and the green manure tree leaves.
