Raphanus sativus Full Sun Soil pH: 6.0 to 7.0
Lettuce interplanted with radish seems to make radishes more tender, radish which matures much quicker than lettuce will help lure early season pests away, flea beetles in particular.
Onion yield is increased when intercropped with Radish. Rapidly maturing early Radish helps prep the soil for onions and there is negligible competition for nutrients.
and Legumes like plants that produce their crop under the soil surface. The radish precedes the legume in germination and in the same scenario with as with carrots, it preps / loosens the soil for the slower maturing legume.
Although early season radishes will not be able to take advantage of the bean or legume nitrogen fixing attributes in the same season, the mature radish will draw pests from the young bean seedlings - a trap crop.
Avoid planting radish with, or in succession with potatoes , as radishes seem to increase the incidence of potato blights such as scab and Black root
Comfrey leaves are recommended to prevent scab.
Please keep in mind that many inter-actions are also percentage based. If an insect that attacks a certain garden plant is repelled by another type of plant - that doesn't mean that absolutely no insects of the genus in question will go near the plants in question - it simply means a much lower percentage than normally would have attacked the plant will show up.
Radishes deter the Cucumber Beetle, planting near plants that are favored by this voracious garden nuisance are advantageous. Cucumber,melons,squash,and pumpkins all benefit from being interplanted with radishes.
Avoid Fennel which is allelopathic to most garden plants. It exudes compounds designed by nature to eliminate competing plants from its immediate area. Dill is one of the few garden crops that can be grown with it.

1. - Intercropping of cabbage, sweet pepper, onion and radish
2. There is some evidence that inter-planting Radish with some varieties of cabbage may result in a decreased cabbage yield, cause unknown - possibly competition or related variables, possibly random variable. See Footnote # 1 -Same Study
